Problems solved by technology

[0010] In the process of realizing the present invention, the inventor found that in the prior art method of determining the priority of each scheduling packet of each frame of the image group, the importance of each scheduling packet is obtained by traversing and decoding different packet loss methods, which requires After many times of decoding, the priority of each scheduling packet of each frame of the image group can be finally determined. The process of determining the priority of the scheduling packet is relatively complicated.

Embodiment 3

[0140] In order to better implement the above method, the embodiment of the present invention also provides a device for determining the priority of scheduling packets, please refer to Figure 4 An apparatus for determining the priority of scheduling packets according to Embodiment 3 of the present invention may specifically include: a frame distortion acquisition module 410 , a code stream interception module 420 , a total distortion acquisition module 430 , a weight acquisition module 440 and a priority determination module 450 .

[0141] The current frame distortion acquisition module 410 is configured to respectively acquire the current frame distortion of the frame image caused by the absence of each enhancement layer in each frame of the first image group.

[0142] The code stream interception module 420 is used to intercept the code stream of the first group of pictures according to the first interception method and the second interception method, and the total number of...

Abstract

The embodiment of the invention discloses a method and a device for determining a priority to schedule packets. In the embodiment of the invention, two different interception modes are adopted to intercept code streams of groups of pictures (GOP), total distortion of each frame of the pictures is obtained by decoding twice under two different interception modes, and the total distortion of each frame of the groups of pictures under different interception modes and current frame distortion of each frame of the pictures in the groups are adopted to obtain the influence weight of each scheduled packet on the group of pictures in each frame to the groups of pictures, thus having relatively less decoding times and greatly lowering the complexity for determining the priority to schedule packets.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and a device for determining the priority of a scheduling packet. Background technique [0002] With the development and widespread application of network technology, the transmission of video information has become one of the important services of network transmission. When performing video transmission on the Internet or mobile network, on the one hand, it is necessary to consider the unstable transmission bandwidth caused by network congestion and channel noise; In the transmission process, the coding and transmission of video information are required to have the characteristics of scalability. [0003] Scalable Video Coding (SVC, Scalable Video Coding) is a video coding scheme developed from the high-compression efficiency video standard H.264 / AVC. SVC can not only provide video space (resolution), quality and time domain (frame rate) It can also provide pack...
