In the embodiment of the invention, when the television end plays the target channel, the electronic program guide navigation information of the target channel can be inquired through an inquiry instruction, wherein the inquiry instruction can be sent by control equipment of the terminal, such as a remote controller or a set top box; the query instruction can also be sent by a third-party device, for example, a mobile phone and a computer have the control authority of the terminal, and send the query instruction to the terminal; the query instruction may also be receiving voice information, and the query instruction is received by recognizing the voice information. The query instruction comprises a channel identification, a query start time and a query end time.
Specifically, step S4 includes:
and S41, determining a target channel corresponding to the channel identifier, and acquiring all event units corresponding to the target channel.
In the embodiment of the present invention, after step S3, the obtained event unit and the association of the channel identifier, which is the number of the target channel identifier, are saved in the database. And when receiving a query instruction, selecting all event units corresponding to the target channel in a database according to the channel identification.
And S42, determining each target event unit in all event units corresponding to the target channel, wherein the event start time of any event unit in each target event unit is greater than or equal to the query start time, and the event end time of any event unit in each target event unit is less than or equal to the query end time.
In the embodiment of the invention, event units with the event starting time and the event ending time both being in the interval from the query starting time to the query ending time are selected from all event units corresponding to the target channel, so as to obtain the target event units. That is, in each target event unit, the event start time of any target event unit is greater than or equal to the query start time, and the event end time of any target event unit is less than or equal to the query end time.
In the embodiment of the present invention, two event start times within 24 hours (00:00 to 24:00) indicate that the first event start time is greater than (equal to \ less than) the second event start time if the value corresponding to the first event start time is greater than (equal to \ less than) the value corresponding to the second event start time.
For example, if the first event start time of the two event start times is 11:01, the second event start time of the two event start times is 11:36, the value corresponding to the first event start time is 1101, and the value corresponding to the second event start time is 1136, then the first event start time is less than the second event start time.
In the embodiment of the present invention, it is assumed that the query start time is 12:00 and the value corresponding to the query start time is 1200, the value corresponding to the event start time of any target event unit is not less than 1200, otherwise, the value corresponding to the event start time of an event unit is less than 1200, and the event unit is not the target event unit.
Similarly, if the query end time is 22:00 and the value corresponding to the query end time is 2200, the value corresponding to the event end time of any target event unit is not greater than 2200, otherwise, the value corresponding to the event end time of an event unit is greater than 2200, and the event unit is not the target event unit.
For example, the query start time is 12:00 (corresponding to a value of 1200), the query end time is 22:00 (corresponding to a value of 2200); assuming that the event start time of an event unit is 10:00, the corresponding value of the event start time of the event unit is 1000, and 1000 is less than 1200, the event unit is not the target event unit; assuming that the time end time of an event unit is 22:01, the time end time of the event unit is 2201, and 2201 is greater than 2200, then the event unit is not the target event unit.
And S43, generating electronic program guide navigation information corresponding to the query instruction according to each target event unit.
In the embodiment of the present invention, after each target event unit is queried, in order to more intuitively and clearly display the situation of each event in the time period to be queried, each target event unit is sorted.
In the embodiment of the present invention, the target event units may be sorted according to the start times of the events respectively corresponding to the target event units, so as to obtain a target event unit list. For example, the target events may be sorted in the order of the event start time of the target event unit from front to back.
For example, for two event start times within one 24 hour period (00:00 to 24:00), assuming that the first of the two event start times is 4:00 and the second of the two event start times is 5:00, the time reaches 4:00 first and then 5:00, 4:00 before 5:00, then the first event start time is before the second event start time and the second event start time is after the first event start time; the target event unit corresponding to the first event start time may be arranged before the target time unit corresponding to the second event start time in the order from the first event start time to the second event start time.
Specifically, for two target event units, if the event start time of the first target event unit in the two target event units is before the event start time of the second target event unit in the two target event units, the first target event unit is arranged before the second target event unit; since two different programs cannot be played simultaneously at the same time, the event end time of the first target event cell is not after the event start time of the second target event cell.
For example, if the event start time of the first target event unit is 8:00 and the event start time of the second target event unit is 9:00, the first target event unit is arranged before the second target event unit in the target event unit list.
In the embodiment of the present invention, the target event units may also be sorted according to the event end times corresponding to the target event units, so as to obtain a target event unit list. For example, the target events may be sorted in the order from the front to the back of the event end time of the target event unit to obtain a target event unit list.
Specifically, for two target event units in the target event unit list, if the event end time of a first target event unit in the two target event units is before the event end time of a second target event unit in the two target event units, the first target event unit is arranged before the second target event unit.
For example, if the event end time of the first target event unit is 15:00 and the event end time of the second target event unit is 16:00, the first target event unit is arranged before the second target event unit in the target event unit list.
In the embodiment of the invention, the event name, the event start time, the event name and the event description information which correspond to each target event unit are displayed in the target event unit list so as to obtain the navigation information of the electronic program list.
In the embodiment of the invention, the electronic program guide navigation information displays all target event units between the query starting time and the query ending time according to the time sequence, and displays the specific content of each target event unit. For example, the time name of a target event unit is "ghost house", the event start time is 9:00, and the event end time is: 11:00, the event description information is: a movie.
In the prior art, different EPG systems correspond to different electronic program guide navigation data with different data formats, and different query modes are required for different EPG systems when querying the electronic program guide navigation information. In the embodiment of the invention, the electronic program guide navigation data respectively corresponding to different EPG systems are all stored in the form of event units, so that different EPG systems can adopt the same query mode to generate the electronic program guide navigation information through the event units, and the compatibility with different EPG systems is realized.
