It should be understood that the specific embodiments described here are only used to explain the present application, and are not used to limit the present application.

PVR recording in a display device or set-top box usually starts recording according to user settings. For example, the user sets to record the playback content of a certain channel for a certain period of time, and when the set recording start time is reached, the recording of the playback content of a certain channel is started. Until the user completes the recording of the broadcast content of a certain channel during the time period set by the user, the target recording file is obtained and the target recording file is stored.

In the embodiments of the present application, it is collectively referred to as the target recording file that the user sets to enroll the broadcast content of a certain channel during a certain period of time. Because the user sets the content to be played in a certain period of time, the target recording file usually includes multiple TV programs, that is, the target recording file includes multiple event contents. For example, the broadcast content of a certain period of time includes different types of programs such as TV dramas and variety shows, or the broadcast content of a certain period of time includes TV programs of different dramas.

In order to display the icon of the target recording file as a thumbnail of the event corresponding to the playback progress, an embodiment of the present application provides a PVR file management method. The PVR file management method provided in the embodiments of the present application is mainly used for display devices or set-top boxes with PVR recording functions, such as smart TVs. Fig. 1 is a flowchart of a PVR file management method provided in the first embodiment of the application.

As shown in FIG. 1, the PVR file management method provided in the first embodiment of the present application includes:

S100: Monitor the playback progress of the target recording file.

S200: Obtain event information corresponding to the playback progress according to the playback progress of the target recording file, and extract clear stream data from the event information, and the icon of the target recording file is displayed as a thumbnail of the clear stream data.

Record the target recording file based on the PVR recording function of the display device or set-top box. Monitor the playback progress of the target recording file, obtain the clear stream data corresponding to the playback progress according to the playback progress of the target recording file, set the thumbnail of the clear stream data as the icon of the target recording file, and display the icon of the target recording file as the clear stream data Thumbnails. The PVR file management method provided in the embodiments of the present application realizes the replacement of the target recording file icon in combination with the playback progress of the target recording file, so that the target recording file icon can intuitively reflect the event corresponding to the playback progress.

In the embodiment of this application, when the recording of the target recording file is completed, in addition to the target recording file generated in the display device or set-top box, a series of other files will be generated, such as event information of each event in the target recording file, such as the event information of each event. Clear stream data, etc. 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 a series of other files related to the target recording file are stored in the folder.

In the embodiments of the present application, before recording the target recording file, the basic event information of each event in the file to be recorded is obtained. The basic event information of each event refers to the event name and event start time of the event included in the target recording file. Optionally, obtain the PVR recording request set by the user, obtain the electronic program guide related to the PVR recording request, and obtain the event basic information of each event of the target recording file in the PVR recording request according to the electronic program guide.

Suppose the user sets to record the TV program in channel N on XX date 13:00-16:00, before starting to record the TV program, according to the PVR recording request related electronic program guide to obtain XX date channel N at 13:00-16:00 The user of the broadcast TV program sets the basic event information in the corresponding target recording file, and records each event and the start time of each event. For example, the file to be recorded corresponding to the user settings obtained through the electronic program guide includes event 1, event 2, and event 3. The start time of event 1 is 13:00, the start time of event 2 is 14:30, and the start time of event 3 It's 15:00.

When the time for the TV program to start playing in the PVR recording request is reached, the PVR recording module starts to record the TV program corresponding to the setting. In the process of recording a TV program, according to the acquired basic event information, the clear stream data of each event in the target recording file is extracted. In the embodiment of the present application, the extracted clear stream data is usually a certain frame of data in the video data in each event. The clear stream data of each event is used to characterize each corresponding event.

Optionally, based on the acquired basic event information, set the time to extract the clear stream data in each event, and extract the clear stream data at that time when the recording of the TV program reaches the moment when the event clear stream data is extracted.

Optionally, in the process of recording a TV program, the clear stream data at the start time of each event in the target recording file is extracted based on the acquired basic event information. In some embodiments of the present application, according to the acquired event basic information of each event in the target recording file, the event changes in the process of acquiring the target recording file are monitored for recording; when the event changes, the first frame of the event is extracted Clear stream data. Usually, the clear stream data at the beginning of each event can better characterize each event. In this way, when recording the TV program in channel N from 13:00-16:00 on XX date, extract the clear stream data corresponding to 13:00 in the recording file according to the start time of the event as the clear stream data of event 1, and extract the target recording file The clear stream data at the corresponding time at 14:30 is used as the clear stream data for event 2 and the clear stream data at the corresponding time at 15:00 in the extracted target recording file is used as the clear stream data for event 3.

In the embodiment of the present application, saving the obtained event clearing data in the format of a cache file is convenient for the use of clearing data on the one hand, and for ensuring the storage security of the clearing data on the other hand. For example, the clear data of event 1, event 2, and event 3 can be named event1.cache, event2.cache, and event3.cache.

In the process of recording a TV program, when the clear stream data of an event is extracted, the event is recorded, such as recording the event number, event start position, event name, and clear stream data. For example, the first event is defined as event1, and the recording start position 0 and the name of the event are saved at the same time; when the event changes after 30 seconds, the second event is defined as event2, the saving start position is 30, and the event name. The event information corresponding to each event is stored for centralized management of each event in the recording file, thereby facilitating the application of the content in the event information in subsequent steps.

Optionally, extract the clear stream data of the first event, record the event number event1, the event start position 0 (the unit can be selected in seconds), the file name1, and the clear stream data event1.cache.

In this way, in the process of completing the recording of the TV program in channel N on XX date 13:00-16:00, the following event information will be obtained:

After recording the target recording file, if the target recording file is played, according to the playback progress of the target recording file, extract the clear stream data from the event information of the event corresponding to the playback progress, and set the clear stream data as the icon of the target recording file. Furthermore, the icon of the target recording file is displayed as the clear stream data. In the embodiments of the present application, it is usually necessary to process the clear stream data before it can be used as the icon of the target recording file, such as adjusting the size and pixels of the clear stream data. Usually, the thumbnail of the clear stream data is set as the icon of the target recording file, so that the icon of the target recording file is displayed as the thumbnail of the clear stream data. For example, when playing a recorded file to the second event in the recording file, the clear stream data in the event information corresponding to the second event is selected as the thumbnail of the recording file. In this way, it is realized that when the recording of the target recording file ends or when the user looks back at the end, the icon of the target recording file is displayed as the content of the event corresponding to the playback progress based on the playback progress of the recording file.

The PVR file management method provided by the embodiment of the application obtains the basic event information of each event in the target recording file before performing the PVR recording of the target recording file; during the PVR recording process of the target recording file, according to the event of each event in the target recording file Basic information, extract the clear stream data corresponding to each event, combine the clear stream data corresponding to each event to form event information corresponding to each event; monitor the playback progress of the target recording file, according to the playback progress of the recording file, the event information corresponding to the event from the playback progress Extract the clear stream data in the, set the thumbnail processing of the clear stream data as the icon of the target recording file, and the icon of the target recording file is displayed as the thumbnail of the clear stream data. In this way, when the recording of the recording file ends or the user looks back and exits, the icon of the target recording file will be displayed as a thumbnail of the event corresponding to the playback progress based on the playback progress of the target recording file. Therefore, the PVR file management method provided by this application can realize the replacement of the target recording file icon in combination with the playback progress such as real-time playback progress or historical playback progress, so that the target recording file icon can intuitively reflect the event corresponding to the playback progress, which is convenient for users A more intuitive understanding of the content of the recorded file based on the playback progress and enhance the user experience.
