Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0036] The main idea of ​​the present invention is: under the situation that decoder and network equipment are all controllable (this requirement can satisfy usually, because solution provider usually can require decoder and network to be provided by oneself, and front-end coder or IPC (IP Network encoder) and other third-party devices), when the decoder finds that it is currently receiving a video stream encoded using the SVC layered coding technology (hereinafter referred to as the SVC video stream), it sends a message. The message includes: a 4-tuple of source IP address, source port number, destination IP address and destination port number of the video stream, and SVC layered decoding package type information. After receiving the message, each netw...

Abstract

The invention provides a method and equipment capable of improving switching virtual circuit (SVC) video flow transmission service quality. The method comprises the steps: an SVC video flow decoder sends a tetrad carrying an SVC video flow and SVC layering decoding combo type information to enable along-the-way network equipment to be capable of learning the tetrad and the SVC layering decoding combo type information of the SVC video flow, and internet protocol (IP) message according with the tetrad is detected in deep layer message mode. Thus, service quality of the SVC video flow transmission is improved without affecting transmission performance of network equipment or increasing network bandwidth consumption.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a method and equipment for improving the service quality of SVC video stream transmission. Background technique [0002] IP video surveillance has become the mainstream and future of the security field. Making full use of the characteristics of the IP network can bring many unexpected benefits to the monitoring business. Due to the existence of different networks and different terminals, customers have more and more urgent requirements on the scalability of video coding. Therefore, SVC technology emerges as the times require. [0003] SVC (Scalable Video Coding) is a technology that splits a video stream into multiple layers of resolution, quality and frame rate. [0004] figure 1 It is a schematic diagram of the H.264 SVC layered structure. The SVC layered coding technology realizes the layered coding of space domain and time domain. Among them, hierarchical coding in the ...
