Embodiment Construction

[0035] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0036] In the following description, unless indicated otherwise, various embodiments of the present application are described with reference to acts and symbolic representations of operations that are performed by one or more computers. Among them, computers include various products such as personal computers, servers, and mobile terminals, and devices that use processing chips such as central processing units (CPUs), single-chip microcomputers, and digital signal processors (DSPs) can all be called computers. It will thus be appreciated that such acts and operations, which are sometimes referred to as computer-implemented, include the manipulation of electrical signals representing data in a structu...

Abstract

The invention discloses a video image data processing method and an apparatus thereof. The method is characterized by according to a current network state, adjusting a sending strategy of video image data stored in a shared buffer area, wherein the sending strategy is used for determining a frame loss proportion corresponding to the shared buffer area according to the current network state; and according to the sending strategy, sending the video image data. By using the technical scheme provided in the invention, an image can be played normally under the condition that a network environment is poor; normal data flow forwarding is realized and frame fluency is ensured.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a method and device for processing video image data. Background technique [0002] At present, Scalable Video Coding (Scalable Video Coding, referred to as SVC) technology is usually used to achieve one-time encoding to generate video compression streams with different frame rates and resolutions, and then according to different network bandwidths, different display screens and terminals The decoding capability selects the amount of video information that needs to be transmitted, so as to realize the adaptive adjustment of video quality. [0003] I frame, which means a key frame, can be understood as a complete reservation of this frame; when decoding, it only needs to have the data of this frame (because it contains a complete picture, and the I frame is a key frame). [0004] The P frame represents the difference between this frame and a previous key frame (or P frame)....
