Method, apparatus, and system for notifying real-time streaming protocol events

An apparatus for notifying a Real-Time Streaming Protocol (RTSP) event, comprises a hardware processor and a non-transitory storage medium, the apparatus is configured to perform operations comprising:

• monitor an RTSP event state for an RTSP event, wherein the RTSP event comprises at least transmission of real-time audio or video data streaming on demand;
• and
• send a notification indicative of a change of the RTSP event state to an RTSP event state receiving device, when the RTSP event state monitoring unit detects that there is a change of the RTSP event state, so as to enable the RTSP event state receiving device to update its RTSP event state to be consistent with the apparatus,
• wherein if the RTSP event occurs at time of monitoring the RTSP event state, the notification carries the information about the occurrence of the RTSP event, and
• if the RTSP event occurs before start of monitoring the RTSP event state and the RTSP event state has changed, the notification carries the information about the changed state of the RTSP event;
• wherein the RTSP event comprises one of a state of playing streaming media and a network state.

A system for notifying a Real-Time Streaming Protocol (RTSP) event, comprising:

• an RTSP event notifying apparatus, configured to monitor an RTSP event state for an RTSP event which comprises at least transmission of real-time audio or video data streaming on demand, and send a notification indicative of a change of the RTSP event state to an RTSP event notification receiving apparatus upon detecting the change of the RTSP event state;
• and
• the RTSP event notification receiving apparatus, configured to receive the notification, and update its RTSP event state to be consistent with the RTSP event notifying apparatus,
• wherein if the RTSP event occurs at time of monitoring the RTSP event state, the notification carries the information about the occurrence of the RTSP event;
• wherein if the RTSP event occurs before start of monitoring the RTSP event state and the RTSP event state has changed, the notification carries the information about the changed state of the RTSP event;
• and
• wherein the RTSP event comprises one of a state of playing streaming media and a network state.
