Video image encoding and decoding device and method thereof, transmission system and method thereof

Abstract

A video image encoding and decoding device and method thereof, transmission system and method thereof, wherein the transmission system includes: a segmentation module, an encoding module, a decoding module and a splicing module, and the segmentation module includes a read-write control circuit, a first line buffer, a second Line buffer, output control circuit, encoding module includes multiple encoding engines, decoding module includes multiple decoding engines, the number of decoding engines and the number of encoding engines are the same as the multiple value, where the multiple value is the video image resolution and encoding The multiple of the module resolution; the first line buffer, the second line buffer and the read-write control circuit are respectively connected to the signal source, and the read-write control circuit is respectively connected to the first line buffer, the second line buffer and the output control circuit , the output control circuit is respectively connected with the first row buffer, the second row buffer and the coding module, and the coding module, the decoding module and the splicing module are connected in sequence. In this way, the encoding, decoding and transmission of video images are realized, and the cost is low and the efficiency is high.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a video image codec device and its method, a transmission system and its method. Background technique [0002] Existing video codec systems generally include a signal source, an encoding module, a decoding module, and a display connected in sequence, and the encoding module and the decoding module are connected through a network. The video signal source outputs a video image, and the encoding module receives the image signal with full resolution and encodes it. The coded video code stream is transmitted to the decoder through the network, and then output to the display after being decoded. Existing video codec systems are suitable for systems with a maximum resolution of 1080p (ie 1920*1080). [0003] With the development of technology, the resolution of video images is getting larger and larger, especially exceeding high-definition images (typical resolution is ...
