Preferred embodiment of the invention

Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a schematic diagram of an implementation process of a recording method of an IPTV broadcast program. As shown in the figure, the following steps may be included in the section directory system:

Step 101: The user terminal sends a reservation recording request to the program list server, where the reservation recording request includes: a program that the user terminal needs to record and that the IPTV will play;

Step 102: The user terminal receives a reservation recording request response sent by the program ticket server, where the reservation recording request response carries the playing information of the program included in the reservation recording request.

Step 103: The user terminal records the program played by the IPTV according to the play information in the reservation recording request response.

In the implementation, when the problem that the IPTV system cannot realize the user reservation recording is solved, when the user determines to select a program that has not started to be played through the program list, the user terminal may send an appointment to the program ticket server in step 101. The recording request server sends a reservation recording request response to the user terminal, and the response carries the playback information of the program to be recorded. After the user terminal receives the reservation recording request response sent by the program list server in step 102, in step 103, The user terminal can record the program played by the IPTV according to the play information in the reservation recording request response, so that when the program to be recorded starts to play, the recording can be realized even if the user is not in the scene. In this process, the user only needs to determine the program to be recorded through the user terminal, and the reservation recording for the program can be completed without the user participating in the program recording in real time. Since user intervention is not required when starting recording, if the user is using other services, such as playing a game, the user terminal can record the reserved program for the user without affecting the user.

In the implementation, it may further include:

The program is recorded when the current time minus the time shift period is before the time the program starts playing.

Since the IPTV system has a time shift function, a complete recording can also be realized for a program that has started to play but does not exceed the time shift range, such as a user terminal after a shutdown and restart. Because the user terminal cannot record after power off, after booting, first check whether each recording task has expired. Due to the time shifting function of the IPTV system, recording can still be performed for certain programs that are out of date but in the time shift range. At this time, the following operations need to be performed to check the programs in the task table one by one: If the current system time - the time shift duration of the program < the start time of the reserved program < current system time, it means that the program has started playing, but the video stream is still completely intact. Existing on the server, in this case, the user terminal establishes a connection with the server, requests to start playing the recording from the start time of the program, and starts the timer at the same time; if the start time of the reserved program <current system time-time shift of the program, If the program has expired, the recording task is not executed; if the current system time <the starting time of the reserved program, it means that the program has not started yet, and the recording can be performed according to the task.

In the implementation, it may further include:

When the program is recorded, the timer is started;

Specifically, the recording timer can be detected periodically. If the timer time ≥ the playing duration of the corresponding program, the recording is stopped, and the corresponding resource is released.

In the implementation, it may further include:

When recording a program, the time at which the program starts playing is established in advance to establish a connection with the media server according to the length of time required to establish the connection.

Specifically, the recording task can be periodically queried. If 0 <start time of the reserved program-current system time ≤ experience value of the time required for the user terminal to establish a connection with the media, it means that the program is about to start playing, then the user terminal immediately establishes with the media server. Connect, start recording. In the implementation, before the user terminal sends the reservation recording request to the program list server, the method further includes: storing, in the user terminal, a reservation recording task table, where the scheduled recording task table includes a program recording task to be performed by the user terminal;

After receiving the reservation recording request response sent by the program ticket server, the user terminal may further include: storing the play information in the reservation recording request response to the reserved recording task table;

When the user terminal records the program played by the IPTV according to the play information in the reservation recording request response, the user can periodically query the reserved recording task table and record according to the reserved recording task table.

The following takes the reservation recording task table as an example, and the user terminal uses the set top box as an example to describe the recording implementation of the IPTV broadcast program. In the implementation, the reservation recording task table is taken as an example because it is easier to manage the tasks of recording programs in this mode, and it is also a relatively common management method; however, in theory, other methods are also possible, in existence When the program recording task needs to be managed, as long as the tasks can be coordinated and managed, the implementation of the reservation recording task table is only used to teach those skilled in the art how to implement the present invention, but it does not mean that only You can use the appointment recording task table. In the implementation process, you can determine the corresponding method according to the practical needs.

During the process of browsing the program list, the user selects the program to be recorded, and the set top box sends a reservation recording request for the program to the program list server;

After receiving the user recording request, the program ticket server sends the related playing information of the reserved recording program, such as the program name, the Uniform Resource Locator (URL) of the program, the time when the program starts playing, and the duration of the program playing. Set-top box.

After receiving the information sent by the program list server, the set-top box compares with the records in the local scheduled recording task table. If the recording task is already in the scheduled recording task list, a prompt box is displayed to remind the user whether to delete the information. Or, update, etc. If there is no such recording task, the information of the program is recorded in the reserved recording task table, and the scheduled recording record is updated to the local storage device. The reservation recording task list in the set top box can be established each time the power is turned on, and the set top box is based on the reserved recording record in the local storage device.

The set-top box periodically queries the reserved user recording task table. If 0 <start time of the reserved program-current system time ≤ experience value of the time required for the set-top box to establish a connection with the media, the program is about to start. During playback, the set-top box immediately establishes a connection with the media server, starts recording, and starts timer counting; the set-top box periodically detects the recording timer, and if the timer time ≥ corresponds to the playing duration of the program, the recording is stopped, the corresponding resource is released, and the task is released from the task. Delete the reserved recording record in the table and the local storage device;

If the set-top box is powered off and then turned back on, you can first create a reservation recording task list by using the reserved program information in the local memory. Because the set-top box cannot be recorded after power-off, after restarting the task table, you must first check whether each task has expired. . Due to the time shifting function of the IPTV system, recording can still be performed for certain programs that are out of date but in the time shift range. At this time, the following operations need to be performed to check the programs in the task table one by one: If the current system time - the time shift duration of the program < the start time of the reserved program < current system time, it means that the program has started playing, but the video stream is still intact. Exists on the server. In this case, the set-top box establishes a connection with the server, requests to start recording from the start time of the program, and starts the timer at the same time; if the start time of the reserved program <current system time-time shift of the program, indicating If the program has expired, the record is deleted from the local storage device and the task table; if the current system time <the start time of the reserved program, it indicates that the program has not started yet;

For programs that have not started recording and have started recording, the scheduled user recording task table and the timing detection recording timer are periodically checked.

For a better understanding of embodiments of the invention, the following description is by way of example.

FIG. 2 is a schematic diagram of a process for implementing a recording method of an IPTV broadcast program of a set top box. As shown in the figure, the following steps may be included when performing program recording:

Step 205, it is determined whether the program already exists in the scheduled recording task table, if yes, go to step 206, otherwise go to step 207;

Specifically, the set-top box can compare the parsed program name and URL with the related information in the scheduled recording task table to see if it already exists in the task table, if it already exists, then proceeds to step 206, otherwise proceeds to step 207;

Step 206, prompting the user that the program has been reserved;

Step 207, the program information is stored in the reservation recording task table and the local storage device; Step 208, according to the program start time to determine whether to start recording, if yes, go to step 210, otherwise go to step 209;

Specifically, the scheduled user record task table can be periodically queried. If 0 <start time of the reserved program-current system time ≤ experience value (tl) of the time required for the set-top box to establish a connection with the media, it means that the program is about to start playing, and the set-top box immediately The media server establishes a connection, performs step 210 to start recording, and starts timer Q1 timing;

Step 209, according to the timer to determine whether to stop recording, if yes, go to step 211, otherwise go to step 208;

Specifically, the timer Q1 that the set top box has been started may be periodically queried. If the time of the timer is ≥ the playing duration of the corresponding program, step 211 is executed to stop the recording, and the corresponding media resource is released; Step 210, start recording, and start the timer Q1. Timing

Step 211: Stop recording, terminate the timer Q1, and release the corresponding media resource. FIG. 3 is a schematic diagram of an implementation process of a recording method of an IPTV broadcast program after the set-top box is powered off and then turned on. As shown in the figure, the following steps may be included:

Step 301: The set top box establishes a reservation recording task table.

Specifically, after the set-top box is powered off and restarted, the reserved program information is obtained from the local storage device, and a reservation recording task table is established;

Step 302: Determine whether the current system time is met - the time shift duration of the program < the start time of the reserved program < current system time, if yes, go to step 305, otherwise go to step 303;

Specifically, the set top box can query each program in the scheduled recording task table. If the current system time-time shift duration of the program <starting time of the reserved program <current system time, perform step 305 to establish a connection between the set top box and the server, requesting the start time from the program. Start playing, start recording, and start the timer at the same time;

Step 303, determining whether the start time of the reserved program is satisfied <current system time - the time delay of the program, if yes, go to step 307, otherwise go to step 304;

Specifically, if the start time of the reserved program <current system time-time shift duration of the program indicates that the program has expired, the record is deleted from the local storage device and the task table;

Step 304, determining whether the current system time is satisfied <the scheduled start time of the program, if yes, go to step 308, otherwise go to step 307;

If the current system time <the start time of the reserved program, it means that the program has not started yet, perform a regular inquiry, and wait for the program to start recording again, otherwise the program has expired, and the record is deleted from the local storage device and the task table;

Step 305, establishing a connection with the media server according to the program URL, starting recording, starting the timer, and proceeding to step 306;

Specifically, the set top box establishes a connection with the server, requests to start playing from the start time of the program, starts recording, and starts a timer at the same time;

Step 306: Regularly check the timer.

Step 307: Delete the program information from the reserved recording task table and the local storage device. Step 308: Regularly query.
