And the monitoring information is reported to the service validity identification module 213; the service validity identification module 213 is configured to request the streaming terminal processing module 214 to play the streaming media terminal, or request to resume streaming media playback from the breakpoint; the service breakpoint processing module 214 is configured to send a service interruption request of the streaming media to the service request access module, or a service recovery request of the streaming media; the service request accessing module 221 is configured to forward the service interruption request of the streaming media to the service control module 222, or the streaming media a service recovery module; the service control module 222 is configured to send a control command for releasing the network resource or allocating the network resource to the network resource management module 223, and sending a control command for releasing the service resource or allocating the service resource to the service resource management module 224, and the flow to the flow Media service module 225 Interrupt streaming media player, a control command or restored from a streaming media at designated time points; streaming media service module 225 for playing the media stream to the user terminal 210 service.

In the embodiment of the present invention, by modifying the function of the user service terminal without using the existing architecture, the method for monitoring the operation behavior of the user terminal is used to determine the validity of the streaming media service. In this way, when the user only closes the playing terminal (such as a television, a display) without closing the user's business terminal (such as a set-top box, a PC host or a service client), or the user does not watch the streaming media content for a long time, the streaming service can be determined. Invalid and timely release of resources allocated for the streaming media service, thereby avoiding long-term unreasonable occupation of resources.

In order to further improve the user experience, when it is determined that the resource needs to be released and the streaming media is terminated, the user service terminal increases the processing of recording the current streaming media playback point information (for the live channel recording channel number, for the on-demand recording program number and the time point), In this way, when the user reopens the playing terminal (such as a television, a display) to continue watching the streaming content, or when the user returns to the streaming content, the monitoring of the user operation according to the service terminal (such as the operation of the set-top box remote control, touch screen operation, etc.) And determining that the streaming media service is re-effective. At this time, the streaming media service is re-allocated resources. If the live channel is broadcasted before the interruption, the live channel is continuously broadcasted. If the on-demand program is broadcasted before the interruption, The on-demand program continues to be played from the location where the broadcast was last terminated, so that the user can continue to watch the last viewed channel or on-demand program. 3 is a flowchart of a third embodiment of a resource configuration method for a streaming media service according to the present invention. This embodiment, in conjunction with FIG. 2, describes a process of invalidation and resource release of a streaming media service, where a user service terminal is assumed to be a set top box. Terminal, the headend system is a VOD system:

Step 301: The user operates the set top box remote controller to drive the input/output interface module in the set top box terminal to switch channels or on-demand programs.

Step 302: The input/output interface module reports the user's playing operation through the set top box remote controller to the user operation monitoring module.

Step 303: When the user operation monitoring module determines that it is a playback operation, requesting to start the streaming service from the service validity identification module.

Step 304: The service validity identification module sets the service state of the current streaming media to a valid state, sets a service invalidation time, and starts a service validity processing timer.

The service expiration time is the time obtained by the current system time plus the service failure duration. The service failure duration is the duration (in seconds) that the user configures through the set-top box configuration function, and can also be written to the interface setting through the set-top box configuration parameters in the VOD system EPG page. In the set-top box, for example, the default service failure time is 10800 seconds (3 hours); the service validity processing timer period is the duration configured by the user through the set-top box system configuration function, and the default period is 600 seconds (10 minutes). Step 305: The input/output interface module sends an advertisement request to the VOD system, requesting the VOD system to play the media stream of the channel or the media stream of the on-demand program.

Step 306: The VOD system allocates resources, receives the media stream of the channel or acquires the media file of the on-demand program, and then broadcasts the media stream to the input/output interface module.
