Embodiment Construction

[0034] Fig. 3 shows a kind of video monitoring system that adopts codec device of the present invention, comprises camera device 310, is used for collecting video picture and gathers / encoder 320, network sender 330, network equipment that are coded to gathering video picture 340, a network receiver 350, a decoder / display 360 and a display screen 370 for decoding encoded data and displaying decoded video images. The codec device of the present invention combines the video collector and the encoder of the traditional digital video signal codec device into one in operation to form a collection / encoder, and combines the decoder and the display of the traditional digital video signal codec device in operation. Two into one becomes the decoder / display.

[0035] Fig. 4 shows the detailed operation flowchart of the acquisition / encoder of the present invention.

[0036] As shown in the figure, the video picture to be encoded is first divided into L groups of video clips, each group of...

Abstract

A low delay coding / decoding device of digital video signal consists of collection-coder for collecting video image and for coding said image, decoding-display for decoding coded data and for displaying decoded video image. It is featured as transmitting data by said coder and said display through network sender and network device as well as network receiver.

Description

technical field [0001] The invention relates to the field of encoding and decoding of digital video signals, in particular to a device for collecting and encoding digital video signals and decoding and displaying digital video signals in a low-delay manner. Background technique [0002] With the development of digital technology, the traditional analog-based video signal processing methods are gradually being replaced by digital-based video signal processing methods. This is even more evident in the field of video surveillance technology. Compared with analog video surveillance technology, digital video surveillance has many advantages such as low transmission bandwidth, easy storage and management, easy encryption and content protection, and low implementation cost. However, some defects are also introduced in the digitization process of the video signal, and one of the important defects is the increase of end-to-end delay. In the analog video surveillance technology, vid...
