Embodiment Construction

[0099] see figure 1 , is a flow chart of the first embodiment of a method for obtaining video coding compression quality in the present invention.

[0100] The method in the embodiment of the present invention can be applied to the sending end for sending video streams, can also be applied to the network side for transmitting video streams, and can also be applied to the receiving end for receiving video streams. The method can include:

[0101] Step 101, acquire video stream information, where the video stream information includes video frame type, video frame size, frame rate and bit rate.

[0102] In the embodiment of the present invention, the video stream information is first obtained, which may include video frame type and size, frame rate and bit rate, and of course may also include other information, such as video frame quantization parameters.

[0103] Among them, the video frame type can specifically be determined by the size of the video frame in the video stream. ...

Abstract

An embodiment of the invention discloses a method and apparatus for obtaining video coding compression quality. The method may include obtaining video stream information including a video frame type, a video frame size, a frame rate and a bit rate; according to the video stream information, calculating video content complexity including time complexity or space complexity or time complexity and space complexity; and calculating video coding compression quality according to the bit rate, the frame rate and the video content complexity. In the embodiment of the invention, the video coding compression quality is obtained requiring only the video frame information, the bit rate, the frame rate and the video content complexity of a video stream, the video coding compression quality is available for use in subsequent video quality assessment, the complexity of the video quality assessment is greatly reduced and real-time assessment can be achieved. Furthermore, with the influence of video content characteristics (i.e. video content complexity) and the frame rate being considered, the assessed coding compression quality accords better with subjective visual feelings of humans.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for obtaining video coding compression quality. Background technique [0002] With the development of network technology, video-on-demand, Internet TV, and videophone have become the main services of broadband networks, and these services will also become the main services of the third generation (3G, the 3rd Generation) wireless network. In the context of the rapid development of network video, how to evaluate the quality of network video conveniently and effectively has become an important problem that needs to be solved urgently in the application of network video. [0003] The network video quality assessment method in the prior art includes a full-reference video quality assessment method, which evaluates the video quality by calculating the peak signal-to-noise ratio (PSNR, Peak Signal to Noise Ratio), and the method generally includes: obtaining...
