Embodiment 1

[0069] This embodiment describes a live monitoring process that does not use the MS to forward the media stream and does not need to be centrally managed by the VM.

[0070] In this embodiment, the media stream message priority adjustment event is configured on the EC corresponding to the media stream of the live monitoring service between the EC and the client in advance, and the media stream message priority adjustment is performed when the set conditions are met. event will be fired. In addition, the policy for adjusting the priority of media stream packets is pre-configured on the EC, so that when the media stream packet priority adjustment event is triggered, the EC adjusts the corresponding media stream according to the policy for adjusting the priority of media stream packets The priority of the packet.

[0071] Media stream packet priority adjustment events may include one or any combination of the following:

[0072] The area alarm event A is triggered when the imag...

Embodiment 2

[0102] This embodiment describes a live monitoring process that does not use the MS to forward the media stream, but needs to use the VM for centralized management.

[0103] In this embodiment, a media stream message priority adjustment event is configured on the EC corresponding to the media stream of the live monitoring service in advance, and the media stream message priority adjustment event will be triggered when the set condition is met. In addition, the policy for adjusting the priority of media stream packets is pre-configured on the VM, so that when a media stream packet priority adjustment event is triggered, the VM instructs the EC to adjust the corresponding media stream according to the policy for adjusting the priority of media stream packets The priority of the packet. Wherein, the type of the media stream packet priority adjustment event may be the same as that in the first embodiment. For the configuration method of the media stream message priority adjustmen...

Embodiment 3

[0126] This embodiment describes a live monitoring process that does not use MS for media stream forwarding but requires centralized management through VM. The difference from Embodiment 2 is that VM can also perform more accurate message priority adjustment according to client information.

[0127] see Figure 4A , which is a schematic diagram of a live monitoring process for forwarding media streams without using an MS provided in an embodiment of the present invention. As shown in the figure, the process may include:

[0128] Step 401 , during the live monitoring service, the EC monitors in real time the media stream packet priority adjustment event corresponding to the media stream setting of the live monitoring service.

[0129] Step 402, when the EC detects that a media stream message priority adjustment event is triggered, it sends a priority adjustment request or an alarm message to the VM, which carries event-related information.

[0130] Step 403, the VM adjusts the...

Abstract

The invention discloses a video monitoring and playback service realization method and video monitoring and playback service realization equipment, which are applied to a video monitoring system. In the method, a media stream message priority regulation event is set corresponding to a media stream of a video monitoring service on a video encoder. The video monitoring and playback service realization method comprises that: the video encoder transmits media stream message priority regulation event related information when the media stream message priority regulation event is monitored to be triggered in a video monitoring service process; and a video management server makes a judgment in regulation over the priority of a media stream message of the corresponding video monitoring service according to the event related information, and transmits indication information to the video encoder or a media switch server according to a judgment result to indicate the video encoder or the media switch server to regulate the priority of the corresponding media stream message according to the judgment result. By the method and the equipment, the media stream message priority can be dynamically regulated.

Description

technical field [0001] The invention relates to video monitoring technology in the field of communication technology, in particular to a method and equipment for realizing video monitoring and playback services. Background technique [0002] With the development of video and audio coding and decoding technology and network storage technology, the image data of the camera is digitized, and transmitted and stored on the Internet network to form a digital video surveillance technology. [0003] Video surveillance technology is a key technology in urban security systems. After several years of development, video monitoring technology has formed an integrated monitoring method of "analog monitoring + network monitoring storage + comprehensive management". The video surveillance system is mainly composed of analog surveillance cameras, video encoders (Encoder, EC), software / hardware decoders, video management servers (Video Management, VM), storage devices, media exchange servers...
