Embodiment Construction

[0043] In the prior art, the method for a server to embed a video image encoded in a pre-encoding manner into a video image encoded in a real-time encoding manner is to superimpose the two video images together according to a certain rule, and the The video image is encoded in real time. Therefore, in the prior art, the server needs to encode the entire frame of the superimposed video image in real time. However, the real-time encoding method requires a higher encoding rate and requires a large amount of calculation. Consuming a lot of system resources for calculations, resulting in excessive server pressure, and when providing services to multiple users at the same time, the number of concurrent channels that the server can provide is small. The embodiment of the present invention aims to reduce the area in the video image that needs to be encoded by real-time encoding, so as to reduce the amount of calculation required for real-time encoding, thereby reducing the pressure on t...

Abstract

The invention discloses a processing method and a processing device of a video image, and aims to solve the problem of heavy server pressure and little concurrent path number in the prior art. The method comprises the following steps: a second video image to be embedded to a first video image is encoded by adopting a predictive encoding method; when the first video image is encoded, the images located out of the embedded zone in the first video image are encoded by adopting a real-time encoding manner; as for the image located in the embedded zone in the first video image, a second video image encoding is directly used as the encoding located in the embedded zone in the first video image. With the adoption of the method, the zones required to be encoded by adopting the real-time encoding method in the first video image are reduced, so that the calculations of the real-time encoding are reduced, the pressure of the server is lightened, and the concurrent path number of the server is improved.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for processing video images. Background technique [0002] Digital video conversion box, also known as set-top box, its basic function is to decode video stream, convert it into video image and display it on TV. [0003] With the development of technology, the needs of users have become more and more diversified. Expanding the functions that TVs can provide so that users can use TVs like computers have become the goals pursued by service providers. [0004] Since the basic function of the TV is to display video images, and the basic function of the set-top box is to decode the video stream, the current method for expanding the functions that the TV can provide is: set up a server with a communication link with the set-top box, The server expands the function of the TV. [0005] When using the above method to expand the function of the TV, the server can ...
