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

Abstract

The invention discloses a video image encoding and decoding device and method thereof and a transmission system and method. The transmission system comprises a segmenting module, an encoding module, a decoding module and a splicing module. The segmenting module comprises a read-write control circuit, a first-line buffer, a second-line buffer and an output control circuit. The encoding module comprises a plurality of encoding engines. The decoding module comprises a plurality of decoding engines. The number of the decoding engine and the number of the encoding engines are the same as multiple values. The multiple values are the multiples of a video image resolution ratio and an encoding module resolution ratio. The first-line buffer, the second-line buffer and the read-write control circuit are respectively connected with a signal source. The read-write control circuit is respectively connected with the first-line buffer, the second-line buffer and the output control circuit. The output control circuit is respectively connected with the first-line buffer, the second-line buffer and the encoding module. The encoding module, the decoding module and the splicing module are sequentially connected. Therefore, video images are encoded, decoded and transmitted, the cost is low, and 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 ...
