Detailed ways

Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

Figure 1 is a schematic diagram of the implementation process of the recording method of the IPTV broadcast program. As shown in the figure, the following steps can be included when recording the program:

Step 101, the user terminal sends a reservation recording request to the program list server, and the reservation recording request includes: the program to be played by the IPTV that the user terminal needs to record;

Step 102, the user terminal receives the scheduled recording request response sent by the program list server, and the scheduled recording request response carries the playback information of the programs included in the scheduled 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.

During implementation, when solving the problem that the IPTV system cannot realize the user's scheduled recording, when the user determines to record a program that has not started to be played through the program list, the user terminal can send the reserved program to the program list server in step 101. For the recording request, the program list server sends a reservation recording request response to the user terminal, and the response carries the playback information of the program to be recorded, so that in step 102, after the user terminal receives the reservation recording request response sent by the program list server, in step 103, The user terminal can record the program played by the IPTV according to the broadcast information in the scheduled 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 present. In this process, the user only needs to determine the program to be recorded through the user terminal, without the user needing to participate in the program recording in real time, and the scheduled recording of the program can be completed. Since the user does not need to intervene when recording starts, if the user is using other services at this time, such as playing games, the user terminal can record the reserved program for the user without affecting the user.

In implementation, it may further include:

After the user terminal is started, determine the time when the program in the broadcast information of the program starts to play, and the time shift duration of the program;

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

Due to the time-shifting function of the IPTV system, complete recording can also be achieved for programs that have started to be played but have not exceeded the time-shifting range, such as user terminals that have been shut down and restarted. Since the user terminal cannot record after power off, it is necessary to check whether each recording task is overdue after starting up. Due to the time-shifting function of the IPTV system, recording can still be performed for some expired programs within the time-shifting range. At this time, you need to perform the following operations 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 scheduled program < the current system time, it means that the program has started to play, but the video stream is still intact It exists on the server. In this case, the user terminal establishes a connection with the server, requests to start playing and recording from the start time of the program, and starts the timer at the same time; if the start time of the scheduled program < the current system time - the time shift duration of the program, It means that the program has expired, and the recording task will not be executed; if the current system time is < the start time of the reserved program, it means that the program has not started yet, and recording can be performed according to the task.

In implementation, it may further include:

When recording the program, start the timer;

When the timing length of the timer is not less than the playing time of the program in the playing information of the program, the recording of the program is stopped, and the resources required for recording the program are released.

Specifically, the recording timer may be regularly detected, and if the timer time is greater than or equal to the playing duration of the corresponding program, the recording is stopped and corresponding resources are released.

In implementation, it may further include:

Determine the length of time required for the user terminal to establish a connection with the media server;

Determine the time when the program in the broadcast information of the program starts to play;

When recording a program, according to the start time of the program, the connection with the media server is established in advance according to the time required for establishing the connection.

Specifically, the recording task can be queried regularly. If 0<the start time of the reserved program - the current system time ≤ the 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, and the user terminal immediately establishes a connection with the media server. Connect and start recording.

During implementation, before the user terminal sends the scheduled recording request to the program list server, it may further include: storing a scheduled recording task table in the user terminal, the scheduled recording task table including the program recording tasks to be performed by the user terminal;

After receiving the scheduled recording request response sent by the program list server, the user terminal may further include: storing the playback information in the scheduled recording request response into the scheduled recording task table;

When the user terminal records the program played by the IPTV according to the playback information in the scheduled recording request response, it can regularly query the scheduled recording task table, and record according to the scheduled recording task table.

The implementation of recording IPTV broadcast programs will be described below by taking the scheduled recording task table as an example and the implementation of a user terminal using a set-top box as an example. In the implementation, the scheduled recording task table is used as an example because it is easier to manage the tasks of recording programs in this way, and it is also a relatively common management method; however, in theory, it is also possible to use other methods. When a program recording task needs to be managed, any method can be used as long as these tasks can be coordinated and managed. The implementation of establishing the scheduled 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 The method of making an appointment recording task table can be used, and the corresponding method can be determined in combination with practical needs during the implementation process.

In the process of browsing the program list, the user selects the program that needs 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's recording request, the program list server will send the relevant playing information of the scheduled recording program, such as the program name, program URL (Uniform Resource Locator, uniform resource locator), the time when the program starts to play, and the duration of the program to the set top box.

After the set-top box receives the information sent by the program list server, it compares with the records in the local scheduled recording task table. If the recording task already exists in the scheduled recording task table, a prompt box will pop up to remind the user whether to delete it. , or updating, if there is no such recording task, record the information of the program into the scheduled recording task table, and update the scheduled recording record to the local storage device. The scheduled recording task list in the set-top box may be established by the set-top box according to the scheduled recording records in the local storage device every time the power is turned on.

The set-top box regularly queries the recording task list of reserved users. If 0<the start time of the reserved program - the current system time ≤ the experience value 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 establishes a connection with the media server. Start recording and start the timer;

The machine reservation box regularly detects the recording timer, if the timer time is greater than or equal to the playing time of the corresponding program, stop recording, release the corresponding resources, and delete the scheduled recording record from the task table and local storage device;

If the set-top box is powered off and then restarted, you can first create a scheduled recording task list through the scheduled program information in the local storage; because the set-top box cannot record after a power failure, so after starting up and recreating the task list, first check whether each task is expired . Due to the time-shifting function of the IPTV system, recording can still be performed for some expired programs within the time-shifting range. At this time, you need to perform the following operations 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 scheduled program < the current system time, it means that the program has started to play, but the video stream is still intact It exists on the server. In this case, the set-top box establishes a connection with the server, requests to start playing and recording from the start time of the program, and starts the timer at the same time; If the program has expired, delete the record from the local storage device and the task list; if the current system time < the start time of the reserved program, it means that the program has not started yet;

For programs that have not yet started recording and have already started recording, regularly query the reservation user's recording task table and regularly detect the recording timer.

In order to better understand the embodiments of the present invention, examples are given below to illustrate.

Figure 2 is a schematic diagram of the implementation process of the recording method of the IPTV broadcast program of the set-top box. As shown in the figure, the following steps can be included when recording the program:

Step 201, the user makes an appointment to record a certain program;

Specifically, when the user browses the program list, he selects the program required to be recorded, and presses the "schedule recording" button set on the set-top box to indicate that the user chooses to record the program;

Step 202, the set-top box sends a program reservation and recording request to the program list server;

Specifically, the set-top box can report the key value to the program list server, and the program list server determines the program requested by the user to record according to the position of the current page focus;

Step 203, the program list server sends the broadcast information of the reserved program to the set-top box;

Specifically, the set-top box receives the program information sent by the program server, and the message format may be as follows: URL=xxxxxxxxx#prgname=program name#prgtype=movie#prgactor=aaa bbb#prgintro=This story is about xXxxxxx, xxxx. Xxxx#Timelength=XXXXXX! #starttime=XXXXXXX#TimeShittURL=XXXXXXX;

Among them, Timelength represents the duration of the program, starttime represents the time when the program starts, and TimeShiftURL represents the time shift length that the program can provide;

Step 204, the STB parses the broadcasting information of the program;

Specifically, the set-top box can analyze the broadcast information from the received reserved program information, such as: program start time, name, broadcast duration, URL, duration that can be time-shifted, and other information;

Step 205, judging whether the program already exists in the scheduled recording task list, if yes, proceed to step 206, otherwise proceed to step 207;

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

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

Step 207, storing the program information in the scheduled recording task table and the local storage device;

Step 208, judging whether to start recording according to the program start time, if yes, proceed to step 210, otherwise proceed to step 209;

Specifically, you can regularly query the recording task list of reserved users. If 0<the start time of the reserved program-the current system time≤the experience value (t1) 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 communicates with the media. The media server establishes a connection, executes step 210 to start recording, and starts the timer Q1 to time;

Step 290, judge whether to stop recording according to the timer, if yes, proceed to step 211, otherwise proceed to step 208;

Specifically, the timer Q1 that has been started by the set-top box can be queried regularly, and if the time of the timer ≥ the playing duration of the corresponding program, then perform step 211 to stop recording and release the corresponding media resources;

Step 210, start recording, and start timer Q1 to time;

Step 211, stop recording, terminate timer Q1, and release corresponding media resources.

Fig. 3 is a schematic diagram of the implementation process of the recording method of the IPTV broadcast program after the set-top box is turned off and turned on again, as shown in the figure, may include the following steps:

Step 301, the set-top box creates an appointment recording task list;

Specifically, after the set-top box is turned off and restarted, the reserved program information is first obtained from the local storage device, and a scheduled recording task list is established;

Step 302, judging whether the current system time-time shift duration of the program<the start time of the reserved program<the current system time is satisfied, 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 - the time shift duration of the program < the start time of the scheduled program < the current system time, perform step 305 to establish a connection between the set-top box and the server, and request to start time from the program Start playing, start recording, and start the timer at the same time;

Step 303, judging whether the start time of the reserved program < the current system time - the time shift duration of the program is satisfied, if yes, proceed to step 307, otherwise proceed to step 304;

Specifically, if the start time of the scheduled program < the current system time - the time shift duration of the program, it means that the program has expired, then delete the record from the local storage device and the task list;

Step 304, judging whether the current system time<the start time of the reserved program is satisfied, if so, proceed to step 308, otherwise proceed to step 307;

If the current system time is less than the start time of the scheduled program, it means that the program has not started yet, perform regular query, and wait for the program to start recording, otherwise it means that the program has expired, then delete the record from the local storage device and the task table;

Step 305, establish a connection with the media server according to the program URL, start recording, start the timer, and proceed 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 the timer at the same time;

Step 306, periodically check the timer;

Step 307, delete the program information from the scheduled recording task table and the local storage device;

Step 308, Periodic Query.
