Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0036] The invention provides a novel multi-channel video transmission system, which can realize multi-channel transmission of high-definition video with a resolution of 1920×1080i or 1920×1080p. The system can meet the transmission requirements of real-time high-definition video. Compared with the commonly used compression transmission systems such as H.264 / AVC and MPEG-4, the system has the characteristics of low cost and low complexity of system development.

[0037] The multi-channel video transmission system of the present invention includes: a sending end and a receiving end.

[0038] The sending end includes: a video source, which provides original video; a video preprocessing device, which is used to complete the ...

Abstract

The invention discloses a multi-channel video transmitting system and method. The method comprises a transmitting end and a receiving end. The transmitting end comprises a video source and a video code flow transmitting device. The receiving end comprises a video code flow receiving device. The transmitting end of the invention further comprises a multi-channel JPEG coder for performing JPEG compression to the video code flow to generate a coded image sequence. The receiving end further comprises a multi-channel JPEG decoder for performing JPEG decompression to the video coded image sequence to generate the video code flow. The invention can fully utilize the parallelism and low complexity of JPEG to compress the high definition video and can make the transmitting bandwidth based on the IP network satisfy the real-time requirement of the high definition video in order to realize the optimal transmitting effect of the high definition video with comparatively low development cost under limited network bandwidth.

Description

technical field [0001] The invention belongs to the technical field of video transmission, in particular to the technical field of multi-channel video transmission, in particular to a multi-channel high-definition video transmission system and method. Background technique [0002] With the development of technical fields such as high-definition video conferencing systems, high-definition video surveillance storage systems, and cable high-definition TV playback systems, high-definition video has penetrated into every corner of society. Excellent high-definition image quality and display characteristics enhance the customer's visual experience and provide more information. The ensuing problems are the sharp increase of storage space and the shortage of transmission bandwidth. Taking 1080p30Hz high-definition video as an example, the amount of data that needs to be transmitted per second is as high as 177 megabytes, while taking Gigabit Ethernet as an example, the theoretical ...
