Description

Method and device for realizing local recording service

Technical field

The present invention relates to the field of communication network technologies, and in particular, to an implementation method and corresponding apparatus for a local recording service.

Background technique

Two kinds of local recording services, namely, c ient Persona l Video Recording (cPVR) service and local time shift service, are carried out in the interactive Internet TV (Internet Protoco l Te levi s ion, IPTV).

The cPVR service is a personalized program recording service based on the channel. During the process of watching the live channel, the user can start recording according to the user operation, for example, pressing the recording button or according to the preset time set by the user, and the set top box records the current time. After watching the channel content, you can keep it, and the recorded content can be saved for a long time until the user deletes it manually.

The local time shift service means that the user can start recording according to the user operation, for example, pressing the pause button during the process of watching the live channel, and the set top box records the currently viewed channel content and temporarily saves the time shifting content in the set top box, usually local time shifting. The method of segmented loop recording is to delete the segments outside the time shift range according to the time shifting duration, so that the total length of the locally saved recorded content is always less than or equal to the time shifting duration. After the local time shift service is started, pause, fast rewind, fast forward and other time shift operations can be realized within the time shift period. When the channel is switched or the power is turned off, the system will stop recording and automatically delete the recorded content. Typically, the system has a preset default time shift, such as 2 hours. In the prior art, when a user views a live channel, after starting the cPVR service or the local time shift service, the content after the current time can only be recorded locally, and the content before the current time cannot be recorded, for example, in the middle of a certain program. The cPVR is started, and the content of the past part of the program cannot be recorded. For example, after the local time shift is started, the content before the startup point cannot be time-shifted.

Step 202: Determine whether the second local recording service is running, in this embodiment, the local time shift service. If yes, go to step 203. If not, go to step 209.

Specifically, the terminal may determine, according to the task manager or the service state machine, whether the local time shift service is currently running.

The second local recording service that is currently running also includes the second local recording service that ends at the current time.

Step 203: Obtain a recording time range and an instantaneous shift range of the local time shift service.

Specifically, the recording time range, that is, the time shift range, may be obtained from the service state machine of the local time shift service.

For example, in this embodiment, the current time is 10: 00, and the time shift range of the local time shift service is 8: 00-10: 00.

The following step 204 is an optional step.

Step 204: Acquire broadcast time information of a program included in a recording time range of the local time shift service.

Specifically, the method is implemented as follows: According to the playing time information of the program in the program list, the playing time information of the program included in the recording time range of the local time shift service is obtained.

For example, in the first example of the embodiment, the content of the two programs P1 and P2 is included in the recording time range, wherein the playing time of the program P1 is 7:30-9:40, and the playing time of the program P2 is 9. : 40-11: 00.

For example, in the second example of the embodiment, the part of the content of the program P1 and the program P3 is included in the recording time range, and the complete content of the program P2, wherein the program P1 is played at a time of 7: 00-8: 10, the program The playback time of P2 is 8: 10-9: 50, and the playback time of program P3 is 9: 50-11: 00.

For example, in the third example of the embodiment, the recording time range includes only part of the content of the program P1, and the playing time of the program P1 is 7: 40-11: 00. Step 205: Presenting prompt information, the prompt information is used to prompt the user to specify the recording start time from the current time or specify the recording start time in the recording time range of the local time shift service or specify the recording time period in the recording time range.

Specifically, the terminal can present the recording time range of the local time shift service, and present recording options such as user-specified recording from the current time, selecting the recording start time in the recording time range, and selecting the recording time period in the recording time range.

Optionally, after the step 204 obtains the play time information of the program included in the recording time range of the local time shift service, the step 205 may be: displaying the play time information of the acquired program and the prompt information, where the prompt information is used. The user is prompted to specify the recording start time from the current time or the recording start time in the recording time range or the recording time period in the recording time range according to the playing time information of the program included in the recording time range of the local time shift service.

For example, in the first example of the embodiment, the time shift range of the terminal presenting the local time shift service is 8: 00-10: 00, the play time of the program P1 is 7: 30-9: 40, and the play time of the program P2. 9: 40-11: 00, and provide a recording option that the user specifies to start recording from the current time, select the recording start time in the recording time range, and select the recording time period in the recording time range. Specifically, four buttons can be presented. They are "recording from the start time of P2", "recording from current time", "custom recording start time in time shift range" and "custom recording time period in time shift range", when the user selects "at" After the time shift range custom recording start time " or "time shift range custom recording start time" button, the input box or draggable time bar will appear further to specify the recording start time or recording time period. The valid input value or draggable time bar of the input box is between 8: 00-10: 00.

For example, in the second example of the embodiment, the time shift range of the terminal presenting the local time shift service is 8: 00-10: 00, the play time of the program P1 is 7: 00-8: 10, and the play time of the program P2 is For 8: 10-9: 50, the playback time of program P3 is 9: 50-11: 00, and the user is specified to start recording from the current time, select the recording start time in the recording time range, and select the recording time in the recording time range. The recording options of the segment, specifically, can be provided with five buttons, namely "recording program P2", "recording from the start time of P3" and "recording from the current time", "custom recording in the time shift range" Start time "and" in the time shift range custom recording time period", will appear further when the user selects "Custom recording start time in time shift range" or "Custom recording start time in time shift range" button Input box or draggable time bar for specifying the recording start time Or the recording time period, the valid input value of the input box or the draggable time bar is between 8: 00-10: 00. For example, in the third example of the embodiment, the terminal presents a time shift range of the local time shift service of 8: 00-10: 00, a play time of the program P1 of 7: 40-11: 00, and provides a user designation from The current time starts recording, selects the recording start time in the recording time range, and selects the recording time of the recording time period in the recording time range. Specifically, four buttons can be provided, which are "recording from the left edge of the time shift", " Recording from the current time ", "In the time shift range Custom recording start time" and "In the time shift range Custom recording time period", when the user selects "In the time shift range Custom recording start time" or "At After the time shift range custom recording start time" button, the input box or draggable time bar will appear further, which is used to specify the recording start time or recording time period, the valid input value of the input box or the draggable time bar is 8: 00-10: 00.

Step 206: Receiving a selection made by the user according to the prompt information, determining a recording option selected by the user. If the user selects to start recording from the current time, the process proceeds to step 209, and if the user specifies the recording start time in the recording time range, Proceeding to step 208, if the user specifies the selected recording time period in the recording time range, the process proceeds to step 207.

For example, in the first, second, and third examples of the embodiment, the user clicks the button "record from the current time", and then determines that the user selects to start recording from the current time, and proceeds to step 209.

For example, in the first, second, and third examples of the embodiment, the user clicks the button "Customize the recording time period in the time shift range" and an input box or a draggable time bar appears, allowing the user to be in time. Two values are specified in the shift range as the recording start time and the recording end time, and the user proceeds to step 207 after inputting or dragging to select the recording start time and the recording end time; or in the second example, the user clicks the button" Recording the program P2", it is determined that the user selects the recording time period in the recording time range, and the recording time period is P2, the playing time is 8:10-9:50, and the process proceeds to step 207.

For example, in the first, second, and third examples of the embodiment, the user clicks the button "Customize recording start time in the time shift range" to appear an input box or a draggable time bar, allowing the user to A value is specified as the recording start time in the time shift range, and the user proceeds to step 208 after inputting or dragging to select the recording start time; or in the first example of the embodiment, the user clicks "start time from P2" Start recording", determine that the user selects the recording start time in the recording time range, and the recording start time is 9:40 of the start time of P2, proceeds to step 208; Or in the second example of the embodiment, the user clicks "record from the start time of P3", determines that the user selects the recording start time in the recording time range, and the recording start time is the start of P3. Time 9:50, proceeding to step 208; or in the third example of the embodiment, the user clicks "record from the time shift left border" to determine that the user selects the recording start time in the recording time range, and The recording start time is the time shift left boundary 8: 00, and proceeds to step 208.

Step 207: Convert the content recorded by the local time shift service in the recording period specified by the user into the recorded content of the cPVR service.

After the step 207 is finished, because the content of the recording period specified by the user has been converted, the first local recording service, that is, the cPVR process ends; according to the user selection or the system setting, the second local recording service, that is, the local time shift service can continue, Can be terminated.

Step 208: Convert the content recorded by the local time shift service between the recording start time and the current time specified by the user into the recording content of the cPVR service, and further continue to record from the current time, and therefore proceeds to step 209.

The recording of the content recorded by the local time shift service in the recording period specified by the user into the recording content of the cPVR service in the step 207 may be: saving the content recorded by the local time shift service in the recording period specified by the user to In the recording directory of the cPVR service, the step 208 converts the content recorded by the local time shift service between the recording start time and the current time specified by the user into the recorded content of the cPVR service, which may be: The recorded content from the recording start time to the current time is saved to the recording directory of the cP VR service.

In order to enable the cPVR service recording content and the local time-shift service recording content to be easily converted, the content is usually recorded in a fragmented manner, and may be sliced according to time or size, and an index file is created for each fragment. The index file records the playback start time and end time of each slice, for example, the broadcast of the slice 1.ts; the start time is 9:00:00, and the playback end time is 9:00:10. Usually, the recording duration of a slice is about 10s.

The local time-shift service records the fragmented loops. The clips outside the time-shift range are deleted according to the time-shift duration. The clips of the cPVR service are saved in the directory and are not deleted unless the user manually deletes the files corresponding to the recording task. Moreover, the content recorded by the local time shift service is stored in a fixed directory, and the recorded content of each cPVR service recording task is stored in a separate directory.

When playing a local time shift service or a file recorded by a cPVR service, the terminal first indexes the file according to the index. The piece calculates the total duration of the current recording file, and adds the recording file and the corresponding index file to the playlist, and automatically plays it in series.

For the step 207, the content recorded by the local time shift service in the recording period specified by the user is converted into the recorded content of the cPVR service. The implementation manner is as follows: The terminal parses the index file generated by the local time shift recording service, so as to find the local time shift. Record all the shards corresponding to the user-specified recording time period recorded by the service; copy the found shards and corresponding index files to the directory corresponding to the cPVR recording task. Optionally, the copied fragment can be renamed, for example, the fragment 1. ts is named pre l . ts , which is convenient for the system to identify the fragment as a fragment converted from the local time-shifted service, and to avoid generation. The fragment is renamed. After the copy is finished, when the user chooses to play the file recorded by the cPVR recording task, the set-top box plays each slice according to the index file sequence, which is the same as the normal cPVR recording and playback. Optionally, if the copied fragment is renamed, the fragment with the prefix pre is played first.

Similarly, the step 208 converts the content recorded by the local time shift service between the recording start time and the current time of the user into the recorded content of the cPVR service, and the implementation manner is as follows: The terminal parses the index generated by the local time shift recording service. File, so as to find all the fragments recorded by the local time shift recording service corresponding to the user-specified recording start time to the current time range; copy the found fragment and the corresponding index file to the directory corresponding to the current cPVR recording task. in.

Step 209: Start the cPVR service.

This step specifically starts recording from the current time and stores the recorded content in the corresponding directory of the cPVR service.

The local time-shift service can continue or terminate depending on user selection or system settings. After the cPVR service is started, the recording may be stopped after receiving the user's instruction to end the cPVR service. For example, the user ends the cPVR service by pressing the recording button again, or automatically stops the recording after the current program ends.

For example, the system setting may be: when the judgment result in step 202 is that the local time shift service is not currently running, or when the user selects to start recording from the current time in step 206, after receiving the user's instruction to end the cPVR service, The recording is stopped; when the step c208 is entered to start the cPVR service step, the recording is automatically stopped after the current program ends.

With this embodiment, the user can share cPVR and local time shift recording while watching the live channel. After the cPVR service is started, the content recorded in the local time shift service that has been started can be converted into the content of the cPVR service, thereby expanding the content of the past recording. For example, when cPVR is started during the playback of the live program, the content that has been played before the current time can be supplemented to record to the complete program, or cPVR can be started after the live program ends, and the completely finished program can be supplemented, thereby improving user experience.

A further embodiment of the present invention provides a flowchart for implementing a local recording service. Referring to FIG. 3, the specific process includes:

Step 301: In the process of playing the live broadcast program, the terminal receives the first local recording service initiated by the user, which is specifically an instruction of the local time shift service in this embodiment.

Specifically, the user may be interested in the current program during the process of watching the live program. When the user wants to watch the current program repeatedly by looking back, the local time shift service is started in real time by pressing the pause button.

Step 302: Determine whether the second local recording service, that is, the cPVR service, is running, if yes, proceed to step 303, and if no, proceed to step 308.

Specifically, the terminal may determine, according to the task manager or the service state machine, whether the cPVR service is currently running.

Step 303: Obtain a recording time range of the cPVR service.

Specifically, the recording time range of the cPVR service is obtained from the service state machine of the cPVR service.

The following step 304 is an optional step.

Step 304: Acquire broadcast time information of the program included in the recording time range of the cPVR service.

Specifically, the method is implemented as follows: According to the playing time information of the program in the program list, the playing time information of the program included in the recording time range of the cPVR service is obtained.

For example, in the first example of the embodiment, the current time is 1 0: 00, the time shift duration is 2 hours, and the current recording time range of the cPVR service is 6: 00-1 0: 00, and the recording time range is included. The content of the two programs PI and P2, wherein the playing time of the program P1 is 6: 00-9: 00, and the playing time of the P2 is 9: 00-11: 00.

For example, in the second example of the embodiment, the current time is 10: 00, the time shift period is 2 hours, and the current recording time range of the cPVR service is 9: 00-10: 00, and the program includes the program within the recording time range. Part of the content of P1, wherein the playing time of the program P1 is 8: 00-11: 00.

Step 305: Presenting prompt information, the prompt information is used to prompt the user to select a recording start time from the current time or specify a distance in the recording time range of the cPVR service that is less than the current time.

Specifically, the terminal can display the recording time range and the time shift duration of the cPVR service, and present the recording for the user to select to start recording from the current time, specify the distance from the current time d in the recording time range of the cPVR service, and the time shift duration. Recording options for the beginning time.

Optionally, after the step 304 obtains the play time information of the program included in the recording time range of the cPVR service, the step 305 may be: displaying the played time information of the acquired program and the prompt information, where the prompt information is used to prompt the user. The recording start time from the current time is selected according to the play time information of the program included in the recording time range of the cPVR service or the recording start time is shorter than the current time in the current recording time range.

For example, in the first example of the embodiment, the recording time range of the terminal presenting the cPVR service is 6: 00-10: 00, the playing time of the program P1 is 6: 00-9: 00, and the playing time of the program P2 is 9: 00-11: 00, and a recording option that provides a user to select a recording start time that is recorded from the current time and specifies a distance from the current recording time range that is less than the current time. Specifically, three buttons may be presented. They are "recording from current time", "recording from P2 start time", "custom recording start time in time shift range", when the user selects "custom recording start time in time shift range" button , the input box or draggable time bar will be further displayed to specify the recording start time, the valid input value of the input box or the draggable time bar is between 8: 00-10: 00.

For example, in the second example of the embodiment, the recording time range of the terminal presenting the cPVR service is 9: 00-10: 00, the playing time of the program P1 is 8: 00-11: 00, and the user selection is provided from the current The time starts recording, and the recording time is specified in the current recording time range. The recording time is shorter than the recording time of the recording time. Specifically, three buttons can be displayed, which are "recording from the current time" and "from the cPVR left". Boundary starts recording "," custom recording in time shift range Start time", when the user selects the "Customize recording start time in time shift range" button, the input box or draggable time bar will appear further, which is used to specify the recording start time, the valid input value of the input box or The draggable time bar is between 9: 00-10: 00.

Step 306: Receiving a selection made by the user according to the prompt information, determining whether the user selects to start recording from the current time, and if yes, proceeding to step 308, and if not, proceeding to step 307.

Specifically, it may be determined according to the recording option selected by the user that the user selects to start recording from the current time or specify a recording start time in which the current time is less than the time shift duration in the recording time range of the cPVR service.

For example, in the first and second examples of the embodiment, the user clicks the button "record from the current time", and proceeds to step 308.

For example, in the first and second examples of the embodiment, the user clicks the button "Customize the recording start time in the time shift range" and an input box or a draggable time bar appears, allowing the user to be within the time shift range. Specifying a value that is less than the current time from the current time as the recording start time, and after the user selects the recording start time by inputting or dragging, proceeds to step 307; or in the first example of the embodiment, the user clicks "from "P2 start time starts recording", it is determined that the recording start time selected by the user is 9:00 of the start time of P2, and proceeds to step 307; or in the second example of the embodiment, the user clicks "starts from the left boundary of cPVR" Recording, determining that the recording start time specified by the user is the recording start time of the cPVR 9: 00, proceeds to step 307;

Step 307: Convert the content recorded by the cPVR service between the recording start time and the current time specified by the user into the recording content of the local time shift service.

The step may specifically be: saving the content recorded by the cPVR service between the recording start time and the current time specified by the user into the recording directory of the local time shift service.

In order to facilitate the conversion between the recorded content of the cPVR service and the recorded content of the local time-shifted service, the content is usually recorded in a fragmented manner, and an index file is created for each fragment. The step can be implemented as follows: The terminal parses the index file generated by the cPVR service, and searches for all the fragments recorded by the cPVR service corresponding to the user-specified recording start time to the current time range; The index file is copied to the directory corresponding to the local time shift service. For a detailed description, reference may be made to the description of steps 207 and 208 of the corresponding embodiment of FIG. 2. Step 308: Start the local time shift service.

This step specifically starts recording from the current time and stores the recorded content in the directory corresponding to the local time shift service.

The cPVR service can continue or terminate depending on user selection or system settings.

After the local time shift service is started, it can be automatically stopped after the user switches channels or after power off.

With this embodiment, when the user watches the live channel, the user can share the cPVR and the local time-shifted recording content, and after the local time-shift service is started, the content recorded in the activated cPVR service can be converted into the content of the local time-shift service, thereby supplementing Recording the past content, expanding the time shift range. For example, when the local time shift service is started during the playback of the live program, the content that has been played before the current time can be supplemented, so that the user can start from the starting point of the current program. Move to improve the user experience.
