The PVR file management method provided by the embodiment of the application realizes the replacement of the target recording file icon by combining the playing progress of the target recording file, so that the target recording file icon can visually embody the event corresponding to the playing progress.
In the embodiment of the present application, when the recording of the target recording file is completed, in addition to the generation of the target recording file in the display device or the set-top box, a series of files are generated, such as event information of each event in the target recording file, for example, the clear stream data of each event, and the like. Therefore, when the PVR recording request set by the user is completed, a folder corresponding to the PVR recording request is generated, and the target recording file and other series of files related to the target recording file are stored in the folder.
In the embodiment of the application, before a target recording file is recorded, event basic information of each event in the file to be recorded is acquired, wherein the event basic information of each event refers to an event name and an event start time of the event included in the target recording file. Optionally, a PVR recording request set by the user is obtained, an electronic program guide related to the PVR recording request is obtained, and event basis information of each event of the target recording file in the PVR recording request is obtained according to the electronic program guide.
Assuming that a user sets and records a television program in a channel N with XX date of 13:00-16:00, before the television program is recorded, acquiring event basic information in a target recording file corresponding to the television program played by the channel N with XX date of 13:00-16:00 according to an electronic program guide related to a PVR recording request, and recording each event and the starting time of each event. For example, the user sets that the corresponding file to be recorded includes event1, event2 and event3 through the electronic program guide, and the start time of event1 is 13:00, the start time of event2 is 14:30, and the start time of event3 is 15: 00.

And in the process of recording the television program, extracting clear stream data of each event in the target recording file according to the acquired event basic information. In the embodiment of the present application, the extracted clear stream data is generally a certain frame data in the video data of each event. Each event inventory data is used to characterize each corresponding event.
Optionally, the time for extracting the clear stream data in each event is set according to the acquired event basic information, and when the recorded television program reaches the time for extracting the event clear stream data, the clear stream data at the time is extracted.
Optionally, in the process of recording the television program, the clear stream data of the start time of each event in the target recording file is extracted according to the acquired event basic information. Preferably, according to the acquired event basic information of each event in the target recording file, monitoring and recording event changes in the process of acquiring the target recording file; when an event changes, first frame streamcast data for the event is extracted. Generally, the clear stream data at the starting time of each event can be more characteristic of each event. Thus, when recording a television program on channel N on XX date 13:00-16:00, 13 of the recording file is extracted according to the start time of the event: the purge data corresponding to the time 00 is used as the purge data of the event1, the purge data corresponding to the time 14:30 in the extraction target recording file is used as the purge data of the event2, and the purge data corresponding to the time 15:00 in the extraction target recording file is used as the purge data of the event3.
In the embodiment of the application, the obtained clear stream data of each event is stored in the format of a cache file, so that on one hand, the clear stream data is convenient to use, and on the other hand, the storage safety of the clear stream data is convenient to guarantee. For example, the purge data for event1, event2, and event3 may be named event1.cache, event2.cache, event3. cache.
During the recording of a television program, when the clear stream data of an event is extracted, the event is recorded, such as recording the number of the event, the start position of the event, the name of the event and the clear stream data. If the first event is defined as event1, and simultaneously, the video recording initial position 0 and the event name are saved; when the event changes after similar 30 seconds, event two is defined as event2, saving the starting location 30, the event name. And storing the event information corresponding to each event for centralized management of each event in the recorded file, thereby facilitating application of the content in the event information in subsequent steps.
Optionally, the clearinghouse data of the first event is extracted, and the number event1, the event starting position 0 (the unit can be selected from seconds), the title name1, and the clearinghouse data event1.cache of the event are recorded.
Thus, in the process of completing recording the television program in channel N on XX date 13:00-16:00, the following event information is obtained:
