Abstract

This invention provides a collection and transmission system for high clear video signals characterizing in including a PC machine of the transmission end, a PC at the receiving end and TS flow transfer device interconnected by networks, in which, said TS flow transfer device has an input interface and an output interface with high clear video signals, said input interface is connected with high clear video collection device, said output interface is connected with the PC machine of the transmission end, which decodes the TS flow to get the original video data via the decode module and codes the original video data by the code module to be decoded and displayed by the PC device, which can realize collection and transmission of high clear video signals.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a high-definition video signal collection and transmission system and method. Background technique [0002] High-definition video is an emerging market demand with broad development prospects and huge market capacity. The standard-definition video signal in the prior art generally has a resolution of 4CIF. Due to its low resolution and insufficient definition, it can no longer meet people's increasing experience needs and some applications that require higher definition. . [0003] The acquisition of high-definition video signals involves a variety of different technologies such as collection, transmission, and encoding and decoding. Due to the characteristics of high-definition video signals with large data volumes and high real-time requirements, the collection and transmission of high-definition video signals are technically difficult. , so it has become a key factor ...
