The above embodiments introduce the content such as the hardware/software architecture and the function implementation of the display device, where the display device may be configured with a video recording function, where a user may start the video recording function at any time when watching a program played in a current period of a certain channel, where the video recording function is to record audio and video data of a program, and store the audio and video data of the program in a local storage space, where the storage space may be a disk or a memory built in the display device, or may also be a storage device externally connected through a USB interface, for example, a USB disk, a hard disk, a card reader, etc., and the user may access the storage space through a specified path, so that the user may play the recorded program resource, thereby watching the previously missed played program, or review the interesting wonderful program many times, without waiting for the program to be rebroadcast.
In one embodiment, program data of a current channel may be transmitted in a code Stream form, after a display device decodes a program code Stream of the current channel and sends the decoded program code Stream to a display to perform foreground display, a time when a video recording function is started is taken as a starting node, a time when the video recording function is stopped is taken as a stopping node, the starting node is taken as a recording period, the display device demodulates a radio frequency signal of the current program received in the recording period to obtain Transport Stream (TS) Stream data, the TS Stream data is processed by a demultiplexer to obtain PES (Packetized Elementary Stream) data, and then the display device stores the PES data in a designated storage space, thereby performing a recording task to realize a video-on-audio mode.
In an exemplary implementation, referring to the channel program playing interface illustrated in fig. 5, to facilitate the user to quickly start the recording function, a recording control 51 may be set on the interface, and if the user is interested in the currently playing program, the user wants to review again later, or if the user is temporarily away and cannot watch the complete program in the current period, the recording control 51 may be triggered to start the recording function, and create a new recording task.
In an exemplary implementation, after the user triggers the video control 51, optionally, a video setting pop-up window 60 as illustrated in fig. 6 is popped up, and several recording modes are provided in the video setting pop-up window 60 for the user to select, where the recording setting page 60 further includes a confirmation control 61 and a first cancel control 62. The confirmation control 61 is used for confirming and submitting the recording mode selected by the user when triggered, the first cancellation control 62 is used for canceling the creation of the recording task when triggered, i.e. the recording function is not started, and setting the first cancellation control 62 can avoid the situation of erroneous recording caused by the user triggering the recording control 51 by mistake.
In an exemplary implementation manner, referring to fig. 7, for example, the first recording mode is "recording only the current program", the channel signal received by the display device may further include channel information, including but not limited to a channel number, a channel name, and current on-playing program information, where the channel information includes but not limited to a program name, a program playing period (which may define a program duration and a start-stop time of the program playing), if the first recording mode is selected by the user, the change presented by the UI layer is that the selection control corresponding to the first recording mode is turned on, and then the user triggers the confirmation control 61, on one hand, the bottom layer of the display device detects the playing progress of the current program according to the program information parsed from the channel signal, and if it is detected that the current program playing is ended, that is, the system clock reaches a timestamp corresponding to the current program playing dead center, the recording task is automatically stopped, the recording function is turned off, and the recording progress is exited, that is, the first recording mode records and stores only the audio and video data of the current program; meanwhile, on the other hand, after the user triggers the confirmation control 61, the UI layer may change to the sub-picture (b) effect of fig. 7, that is, close the recording setting pop-up window 60, and display the recording status identifier 52 on the current channel program playing interface, where the recording status identifier 52 in the mode one is, for example, "recording the current program", "recording completed", etc., so that the user can know the recording status and progress of the program when watching the current program.
In an exemplary implementation, referring to fig. 8, the sub-picture (a), for example, the recording mode two is "custom recording end time", where the recording mode supports that the user sets the end time of recording according to his actual situation, for example, the user needs to go out temporarily and estimates the departure time to be one hour, then the video content to be played in the next hour of recording the current channel may be selected from the current time, and the video content recorded in this mode may relate to one or more programs because each channel program has a designated playing duration and time period requirement. If the user selects the second recording mode, the UI layer presents a change that the selection control corresponding to the second recording mode is turned on.
In an exemplary implementation, after the user selects the selection control of the recording mode two, a time input control is presented, and the first time input control 63 is illustrated in the sub-graph (b) of fig. 8, and the user inputs the recording end time, specifically, the year, month, date and minute, through the time input control 63, so that the time unit can be further thinned to seconds; alternatively, subplot (c) of fig. 8 illustrates a second time input control 64, where the user directly inputs the recording duration, which is the time interval between the start and end of recording, through the time input control 64, and the recording duration is, for example, minutes, and may be input in the time input control 64 if the user needs to go out for one hour60min, recording end time=start time+recording duration. User input control 63 via timeOr the time input control 64, after inputting the desired recording end time, triggers the confirmation control 61, on the one hand, the UI layer may change to the sub-graph (d) effect of fig. 8, that is, close the recording setting popup window 60, and display the recording status identifier 52 on the current channel program playing interface, where the recording status identifier 52 in the second mode is, for example, "recording the program of the current channel, predicting the xxx time", "completing the recording this time", etc.; meanwhile, on the other hand, the display equipment creates and starts to execute a corresponding recording task according to a recording mode II selected by a user and defined recording end time, automatically stops executing the recording task when detecting that a system clock reaches the recording end time, closes a recording function, exits a recording process, and changes a prompt of a recording state identifier 52 to be 'complete the recording'.
In an exemplary implementation, referring to fig. 9, the sub-graph (a), for example, the third recording mode is "trigger the recording button again to stop recording", when the user triggers the recording control 51 once, the display device displays the recording setting popup 60, and generates and starts to execute the recording task according to the setting and confirmation operation of the user in the recording setting popup 60, and during the execution of the recording task, the user can trigger the recording control 51 twice at any time to end recording. After the user selects the third recording mode, the UI layer in the subpicture (a) of fig. 9 shows that the selection control corresponding to the third recording mode is turned on, and then the user triggers the confirmation control 61, on one hand, the UI layer can switch to the subpicture (b) effect of fig. 9, that is, close the recording setting popup window 60, and display the recording status identifier 52 on the current channel program playing interface, where the recording status identifier 52 in the third mode is, for example, "recording the current program, you can click the recording button at any time to finish recording", "recording is completed at this time", and so on; meanwhile, on the other hand, the display device creates and starts to execute a corresponding recording task according to the recording mode III selected by the user, and automatically stops executing the recording task when receiving an operation instruction of triggering the recording control 51 for the second time, closes the recording function, exits the recording process, and changes the prompt of the recording state identifier 52 to 'complete the recording'.
In an exemplary implementation manner, for example, due to factors such as a tuner fault and communication abnormality, the display device cannot receive the radio frequency signal of the current channel, the current program cannot be normally played, and the current program cannot be effectively recorded naturally, so if a failure of recording start is detected, a user can be prompted to fail to record, and a recording task of the current program is canceled.
Because the display device is mostly configured with only one tuner, the limitation of the hardware configuration can cause conflict between program recording and channel switching, referring to the operation logic of program recording and channel switching illustrated in fig. 10 (a), firstly, a user switches to channel 1, channel 1 is currently broadcasting program a, then the user triggers a video recording control to start video recording of program a, and at the moment, program a is in a video-on-video state; before the recording of the program a is finished, if the user wants to switch to the channel 2, he or she has to stop recording of the program a, after the recording process of the program a is terminated, the display device can respond to the channel switching instruction and switch to the channel 2, and display the currently on-broadcasting program B of the channel 2, at this time, the display device does not execute any recording task, and the user can continue to watch the program B, or can switch to other channels again.
Referring to the UI example provided in fig. 10 (b), in the scenario where the program a is currently being recorded, if the display device receives an operation instruction to switch to channel 2, the display is controlled to display a prompt pop-up window 100, in which query information 101, a second cancel control 102, a save control 103, and a delete control 104 are displayed in the prompt pop-up window 100. The inquiry information 101 is used for inquiring whether to store the recorded file before stopping recording, if the user triggers the second cancellation control 102 after browsing the inquiry information, the stopping action of the recording task of the program a is cancelled, and the program a is not responded to the channel switching instruction, namely the broadcasting-recording-while-recording state of the program a is still maintained, and the channel 2 is not switched; if the user triggers the save control 103, immediately stopping recording the program A, saving part of audio and video data of the program A which is recorded until the current time in a designated storage space, and then switching to a channel 2 in response to a channel switching instruction; if the user triggers delete control 104, recording of program A is immediately stopped, the recorded file is deleted (i.e., not saved), and then zapping to channel 2 in response to the channel switch instruction.
As can be seen from fig. 10 (a) and fig. 10 (b), for the display device with single tuner configuration, only the recording task being performed is terminated to switch channels, which results in insufficient recording, the recorded file does not cover the complete program content, if the recording task is naturally ended and then the channel is switched, the user may miss the wonderful program of watching other channels, that is, the recording and the switching cannot be compatible under the single tuner hardware configuration, and the user can only select one of the two channel programs played in the same time period to watch. Although the tuner is additionally arranged for the display device, so that the number of the tuner is two, the problems can be overcome, the hardware configuration of the display device is required to be modified, the hardware cost is increased, and the problem solving mode is not universal.
To overcome the problem of conflict between video recording and channel switching, in one embodiment, fig. 11 illustrates a method of channel switching in a video recording state, which is performed by the controller 250 of the display device, comprising the following program steps:
step S01, displaying the first program currently on the channel.
For convenience of description, the program played in the current time period of the current channel is called a first program, and the first program may be in a play state only or in a recording-while-playing state.
Step S02, receiving a channel switching instruction.
The Channel switching instruction may be generated according to a triggering operation of a user on a Channel switching key, where the Channel switching key includes a channel+ and a Channel-, where the channel+ may be switched to a next Channel of a current Channel when triggered, and the Channel-may be switched to a previous Channel of the current Channel when triggered, and the Channel switching key may be disposed on a body of the display device, or the Channel switching key is a key disposed on a remote controller in communication with the display device. Or the user calls out the full channel list on the channel program playing interface, and quickly selects the interested target channel from the full channel list, and thus generates a channel switching instruction pointing to the target channel. The full channel list comprises all channels transmitted by a plurality of frequency points which can be received by the display equipment.
Step S03, detecting whether the first program is in a recording state. If the first program is in the recording state, executing step S04; if the first program is only in the play state and not in the record state, step S07 is executed.
Step S04, detecting whether the current channel and the target channel indicated by the channel switching instruction are in the same frequency point. If the current channel and the target channel are in the same frequency point, executing step S05 and step S06; if the current channel and the target channel do not belong to the same frequency point, step S08 is executed.
And step S05, continuing recording the first program in a background mode.
Step S06, responding to the channel switching instruction and displaying the second program on the target channel. For convenience of description, the program played in the current time period of the target channel after switching is called a second program.
Step S07, immediately responding to the channel switching instruction, and displaying the second program on the target channel.
Step S08, prompting that the target channel cannot be switched, and returning to step S02.
In this embodiment, since a frequency point transmits signals of multiple channels at the same time, if the current channel and the target channel belong to the same frequency point, the display device may receive program code stream data of the two channels before and after channel switching in the current period from the frequency point at the same time, even if the user switches from the current channel to the target channel, the code stream data of the original channel before channel switching in the channel will not interrupt transmission, so the display device may perform background recording on the first program, that is, record and store only the first program, stop decoding and foreground display audio and video data of the first program, then switch to the target channel in response to the channel switching instruction, and decode and display audio and video data of the second program.
Referring to the program recording and channel switching operation logic illustrated in fig. 12, firstly, a user switches to channel 1, channel 1 is currently broadcasting program a, then the user triggers a recording control to start recording of program a, and at this time, program a is in a broadcasting-while-recording state; before the recording of the program a is finished, if the user requests to switch to the channel 2 at the same frequency point as the channel 1, the prompt popup window 100 of fig. 10 (B) is not displayed, that is, the recording process of the program a does not need to be exited, only the background is needed to continue recording the program a, and the switching to the channel 2 is allowed, at this time, the program a is in the state of only the background recording but the foreground is stopped, the program B of the channel 2 in the current period is in the state of the foreground playing, the user can continue to watch the program B, and the user can also select to switch to other channels at the same frequency point as the channel 1. Whether any one of the first recording mode to the third recording mode is implemented, the recording process of the program A can be terminated as long as the recording finishing condition of the proper matching mode is met, the user is prompted that the program A is recorded, the subsequent user can access the designated storage path at any time to check the recorded file, and the recorded program resource can be repeatedly reviewed.
As can be seen from a comparison between fig. 12 and fig. 10 (a) and fig. 10 (b), the present application does not need to terminate the recording process of the first program before channel change, and supports switching to the target channel of the same frequency point in the recording scene of the program, so as to avoid the user missing the second program played in the same time period of the target channel, and after the user finishes watching the second program, the user can review the recorded first program in the local storage, thereby overcoming the defect that the user can only watch the program of one channel due to the playing time conflict. According to the application, under the single tuner hardware configuration, the compatibility of program recording tasks and channel switching operation is realized through the innovation of the bottom software program, the limitation of the hardware configuration of the display equipment is broken through, more tuner is not needed, the hardware cost of the display equipment is not increased, and the functional experience of video recording service is improved.
For the foregoing method embodiment, when switching channels in the first catalog scene, it is necessary to detect whether the target channel 1 and the current channel belong to the same frequency point, and if so, the channel can be switched to the target channel 1 directly; if the channel is not in the same frequency point, the user is prompted that the user cannot switch to the target channel 1, the user switches to the target channel 2, the display device detects whether the target channel 2 and the current channel belong to the same frequency point, and the user can input one or more channel switching instructions to finally locate the switchable/playable channel in the same frequency point as the current channel.
In practical application, the channel list may include tens or even hundreds of channels, which is affected by factors such as signal quality and ordering rules, and the position distribution of N channels supported by the same frequency point in the channel list is irregular, for example, the positions of N channels are not adjacent, not concentrated, and are far apart, so that the following problems are encountered when a user switches a channel: (1) when a user switches channels by Channel +/-, the user can position the Channel closest to the current Channel through a series of intermediate channels, the operation of the user is complicated, and the Channel positioning and switching efficiency is low; (2) when a user changes channels through a full channel list, the number of channels in the list is numerous, the position distribution of switchable/playable channels which are in the same frequency point with the current channel is irregular, the user cannot accurately identify the channels with the same frequency point and the channels with different frequency points in the list, the user does not know which channels in the list are switchable, the time consumption of channel-by-channel trial is long, and the problems can influence the experience of the user when switching channels.
Based on a further improvement of the foregoing method embodiment, in another embodiment, a method for switching channels in a video recording state is illustrated with reference to fig. 13, which is also executed by the controller 250 of the display device, comprising the following program steps:
step S11, displaying the first program currently broadcast by the channel.
Step S12, when receiving a recording request for the first program, starting recording and storing the audio and video data of the first program, and generating a sub-channel list.
The sub-channel list comprises channel information of a current channel and a plurality of switchable channels which are positioned at the same frequency point as the current channel, namely all channels which can be transmitted by the frequency point where the current channel is positioned are gathered in the sub-channel list, and the channel information of the channels with the same frequency point is recorded, wherein the channel information comprises but is not limited to channel numbers, channel names, program information and the like. The sub-channel list corresponds to a subset of the full channel list.
After the sub-Channel list is generated, the user can switch channels by two operation modes, one through a Channel +/-key and the other through tuning out of the full Channel list and quickly selecting a target Channel to switch to in the full Channel list, so that a zapping mode one or a zapping mode two can be performed after step S12.
The channel switching mode corresponds to switching channels through the channel list, and comprises the steps S13 to S16:
step S13, receiving a channel list display instruction.
Step S14, displaying a full channel list at a preset position on the playing interface of the first program, setting the channel information in the sub channel list to be in a selectable state, and setting the other channel information except the sub channel list in the full channel list to be in an unselected state.
In an exemplary implementation, referring to the UI effect diagram of displaying the full channel list in the first catalog scene illustrated in fig. 14, the full channel list may be displayed in a preset plate at a preset position of the program playing interface, for example, the full channel list is displayed on the right side of the screen in fig. 14, and the channel information items in the full channel list are sorted in columns. The full channel list comprises the generated sub-channel list, and also comprises channels and channel information thereof which are transmitted by other frequency points except the sub-channel list and can be received by the display equipment. Since the present application supports the user to arbitrarily switch channels in the sub-channel list, the channels in the sub-channel list are in a selectable state, and the channels included in the (full-channel list-sub-channel list) are in an unselected state. In the actual UI display, referring to fig. 14, for example, each item of channel information included in the sub-channel list may be set to be highlighted or added with an effect such as color, so that the sub-channel list is more striking and highlighted, and the non-selectable channel information is gray, so that the user can know which channels can be switched to through the significant difference and contrast between the same-frequency channel and the non-same-frequency channel in the display effect.
In an exemplary implementation manner, referring to fig. 14, in order to facilitate channel switching for a user, a position may be selected from a full channel list to directly insert a sub channel list, so that channel information included in the sub channel list may be displayed in a centralized manner, channels of the same frequency point may be adjacent and continuously distributed, and a gap between switchable channels in the same frequency point may be reduced to the greatest extent, which is more beneficial for the user to switch channels quickly.
In an exemplary implementation, the insertion position of the sub-channel list is defined by taking the relative position of the current channel in the full channel list as a reference and combining the sub-channel sorting rule (e.g. sorting from small to large according to channel numbers, etc.), referring to fig. 14, it is assumed that the sub-channel list includes channel 9, channel 11, channel 12 and channel 34, where channel 11 is the current channel, and the program of channel 11 is in a recorded-while-broadcast state, and when the user tunes out the full channel list in this scenario, based on channel 11, the positions of channel 11 and channel 12 in the full channel list are unchanged, channel 9 is swapped with original channel 10 (grey), channel 34 is swapped with original channel 13 (grey), so that the channels in the sub-channel list can be swapped together for display through simple replacement between the channel positions.
In an exemplary implementation, for example, the sub-channel list is also sorted in ascending channel numbers, and the channel sorted first in the sub-channel list is used as a reference channel, then the order i of the reference channel is used as the head of the sub-channel list, then the sub-channel list occupies the ith to the (i+n) -1 th order, then other channels originally sorted after the reference channel in the whole channel list are synchronously down-tuned, and N is the number of channels included in the sub-channel list. Assuming that the sub-channel list includes channel 9, channel 11, channel 12 and channel 34, taking channel 9 as the reference channel, i.e. i equals 9,N equals 4, then the 9 th to 12 th order bits in the full channel list are occupied by channel 9, channel 11, channel 12 and channel 34 in turn, original channel 10 (gray) is down-turned to 13 th order bit, original channel 13 (gray) is down-turned to 14 th order bit, and so on, refreshing the channel arrangement of the full channel list, completing the insertion of the sub-channel list, and because the current same-frequency channels are adjacent, the user does not need to turn pages or slide the channel list to search for the optional channels.
In an exemplary implementation, when the channel list is tuned out in the first catalog scenario, only channels with the same frequency point in the sub-channel list are supported to be switched, so when the channel list display instruction is received, only the sub-channel list can be displayed, and other non-switchable channels in the full channel list are not displayed any more. The setting of the related content such as the display effect and the display position of the sub-channel list is not limited to the embodiments of the present application.
Step S15, when receiving the selection operation of the target channel in the sub-channel list, generating a channel switching instruction according to the channel information of the target channel.
The user can select the interested target channel by referring to the channel information and the program information displayed in the sub-channel list, and the channel switching instruction can be generated by triggering the jump link of the target channel, and the channel switching instruction is used for switching to the target channel pointed by the user after being responded.
And step S16, continuing to record the first program in a background mode, and responding to the channel switching instruction, and displaying a second program on the target channel.
The Channel switching mode II corresponds to Channel switching by clicking a Channel +/-key and comprises the following steps of S17 to S19:
step S17, receiving a triggering instruction of a user to a channel switching key.
The Channel switching key comprises a channel+ key and a Channel-key, and the channel+ key needs to be switched to a Channel which is sequenced at the next sequence position of the current Channel when a user presses/clicks once every short time; every time the user presses/clicks the Channel-key a short time, it is necessary to switch to the Channel ordered in the previous order of the current Channel. If the user presses the Channel +/-key for a long time, the duration of the key duration can be converted into the number of single-click times, and the Channel to which the user triggering instruction is switched is positioned by combining the switching direction indicated by the Channel switching key type.
And step S18, continuing recording the first program in a background mode.
And S19, positioning the target channel in the sub-channel list according to the switching direction indicated by the channel switching key by taking the current channel as a reference, and displaying the second programs which are batched to be broadcast by the target.
For the Channel +/-key triggered by the user, the Channel is positioned and switched in the sub-Channel list until the user selects and watches the interested Channel program, and the Channel which cannot be switched in the full-Channel list is automatically filtered, so that the Channel switching efficiency of the user is greatly improved, invalid Channel switching (namely, the condition that the prompt cannot be switched to the target Channel) is avoided, and better operation experience is provided for the user.
It should be noted that, the mode, the setting option, the creating and executing modes, and the channel cutting mode of the recording task are not limited to the implementation manner provided by the present application, and the screen UI layer presentation associated with the recording function and the channel switching is also merely exemplary, and does not constitute limitation on the UI display and the user operation of the actual product, specifically, the design and the application of the actual product should be in control.
