Description

A kind of system and method for timed recording TV programme

Technical field

The invention belongs to multimedia technology field, relate in particular to a kind of system and method for timed recording TV programme.

Background technology

Along with Web TV constantly develops, nowadays the function of TV is more and more, become increasingly complex, and the hardware resource of TV itself is limited, at synchronization, can only accomplish one or a few task.When TV when a functional status switches to the another one functional status, possibly stop current functional status, discharge resource.Because the switching of functional status needs the regular hour, the inaccurate problem of recording time occurs for traditional timed recording meeting in red-letter day.And when the user carries out a certain feature operation,, cause the problem of TV resource mutual exclusion because the timed recording of TV need take a certain limited resources of current use and need stop current functional status.Such as: manually recording of user carried out, and the frequency of timed recording and current frequency are different, at this moment can have the use mutual exclusion of signal tuning unit, influence user's experience greatly.

Summary of the invention

The invention provides a kind of system and method for timed recording TV programme, be intended to solve in the prior art because the switching of functional status causes the inaccurate and timed recording of timed recording Pgmtime to take current use resource and cause the TV resource to use the problem of mutual exclusion.

The present invention is achieved in that a kind of system of timed recording TV programme, comprises system peripheral interface, display unit, time system, signal tuning device, controller and user preset information management unit; Said system peripheral Interface and Controler link to each other, and be used for the user reserved recorded information is set, and said display unit links to each other with controller; The information that is used for display system; Said time system links to each other with controller, is used to manage the time of whole system, and said signal tuning device links to each other with controller; Be used for programme signal is carried out code stream packing and shunting; Accomplish the tuning of signal, the work that said controller is used to control user's operation and coordinates other module, said user preset information management unit links to each other with controller; Be used for the reserved recorded information that leading subscriber is provided with, and monitor the current time in the acquisition time system to the time of program recording.

Technical scheme of the present invention also comprises: the system of said timed recording TV programme also comprises data storage cell, and said data storage cell links to each other with controller, is used to preserve reserved recorded information and the recorded program content that the user is provided with.

Technical scheme of the present invention also comprises: whether said reserved recorded information continues to record etc. when comprising time period and the resource contention of program channel, pre-recording of pre-recording.

Another technical scheme that the present invention takes is: a kind of method of timed recording TV programme may further comprise the steps:

Step a: start the timed recording function, reserved recorded information is set;

Step b: the frequency P1 that obtains current visual tuning reaches the tuning frequency P2 from a nearest pre-recording of current time;

Step c: whether the frequency P1 that judges current visual tuning is the same with the tuning frequency P2 of pre-recording, if the same, changes steps d over to;

Steps d: begin recording of TV programme.

Technical scheme of the present invention also comprises: in said step a, whether said reserved recorded information continues to record when comprising time period, the resource contention of subscription channel, pre-recording.

Technical scheme of the present invention also comprises: in said step a, the user is provided with reserved recorded information and specifically comprises: obtain current available channel information; The user selects subscription channel, information such as whether continues to record when time period and the resource contention of pre-recording is set; The newly-installed pre-recording of user time and pre-recording time of having stored are done the repeatability inspection; Judge whether newly-installed pre-recording time and the pre-recording time of having stored repeat; If newly-installed pre-recording time and the pre-recording time of having stored repeat; Reselect subscription channel; The pre-recording time is set,, then preserves the reserved recorded information that the user is provided with if the newly-installed pre-recording time did not repeat with the pre-recording time of having stored.

Technical scheme of the present invention also comprises: said step c also comprises: the tuning frequency P2 of the frequency P1 of current visual tuning and pre-recording is different, and certain hour prompting user pre-recording will begin before pre-recording begins, and stop current visual tuning.

Technical scheme of the present invention also comprises: said step c also comprises: whether judges selects to continue to carry out pre-recording; If the user selects to continue to carry out pre-recording; Stop the tuning frequency P1 of current TV; Change the tuning frequency P2 of pre-recording over to,, then finish this and record if the user selects cancellation to carry out pre-recording.

Technical scheme of the present invention also comprises: also comprise between said step c and the d: begin to record for the previous period, and the operational order of limited subscriber, and prompting user pre-recording begins.

Technical scheme of the present invention also comprises: said steps d also comprises: remove the restriction to user instruction.

Technical scheme of the present invention has following advantage or beneficial effect: the present invention is through analyzing comparison to current visual tuning and pre-recording are tuning before pre-recording begins; Carry out tuning conversion according to user's request; In the pre-recording process; TV functions state to current TV functions state and user's pre-recording carries out the analysis of resource alternative; And carry out function according to user's request and switch, improved the time accuracy of timed recording function, avoid because the TV resource that the switching of functional status causes is used the problem of mutual exclusion.In addition, the present invention is simple to operate, and is easy to use, improves user's experience greatly.
