Network video image processing method and device

Abstract

The invention provides a network video image processing method and device. The network video image processing method includes the steps that S1, a server encodes one or more images in a video program; S2, the server receives and responds to a playing request for the video program of a playing terminal, wherein the S2 includes the following steps that S100, the server receives the playing request of the playing terminal, and the playing terminal designates a viewing image Sa or the server designates the viewing image Sa; S200, the server selects one or more coding code streams related to the image Sa from the coding code streams; S300, interaction behaviors of users are collected to form playing behavior information PA, and the playing behavior information PA is fed back to the server; S400, if the playing behavior information PA is received, a viewing image range UV or a viewing object UO is obtained through the playing behavior information PA; S500, if the viewing image range UV or the viewing object UO is obtained, an image Sb is obtained on the basis of the UV or the UO; if the video program does not contain the image Sb, the video program is made to contain the image Sb; then the Sa is made to be equal to Sb, and the step S200 is returned.

Description

technical field [0001] The invention relates to the technical field of Internet video information, in particular to a method and device for processing network video images. Background technique [0002] In recent years, with the vigorous development of Internet video services at home and abroad, users have put forward higher and higher requirements for video picture quality and interactivity during viewing. [0003] The playback capabilities of various playback terminals used to watch video content are limited, especially for various smart mobile terminals facing the mobile Internet, their display resolution and decoding capabilities also have upper limits, and when acquiring videos through the network and performing When playing, the network access bandwidth is also limited. When adaptive multi-bit rate, the playback terminal can select the appropriate bit stream according to its decoding capability and network bandwidth. For example, when the network bandwidth is low, sel...

Problems solved by technology

However, this method has many problems: if the code rate or resolution of the encoded code stream is low, the image details are already quite different from the original signal source, so that a better image effect cannot be achieved after directly enlarging the local area; If the coded stream directly uses a high-bit-rate, high-resolution coded stream, it will occupy a relatively high network bandwidth, and the decoding resource overhead will be large. If the network bandwidth or display resolution and decoding capabilities of the playback terminal are limited , you will not be able to receive or play the above coded stream

[0008] If the code stream transmitted to the playback terminal adopts a code stream with a code rate of 1Mbps, a resolution of 720x576, and a code stream that encodes a complete picture, after the playback terminal zooms in on a local area, the zooming process will result in more distortion and poor picture details;

[0009] If the code stream transmitted to the playback terminal adopts a code stream with a code rate of 1Mbps, a resolution of 1920x1080, and a code stream that encodes a complete picture, the image encoding process will cause more distortion. After the playback terminal zooms in on a local area, the picture details will also be poor. , and some playback terminals may not be able to support the decoding and playback of encoded streams with a resolution of 1920x1080;

[0010] If the coded stream transmitted to the playback terminal is encoded with a bit rate of 8Mbps and a resolution of 1920x1080, the network bandwidth of the playback terminal may not be able to carry it, resulting in playback freezes and other phenomena, and some playback terminals may not be able to support the resolution 1920x1080 encoded stream decoding playback

[0011] To sum up, we need to find a way to watch different images of the video and improve the quality of the video image under the condition of limited playback terminal resources, so as to avoid the video image quality from being significantly reduced due to the adjustment of the image
