Abstract

The invention provides a method and device for transmitting a high-definition video, and the method comprises the steps: carrying out the separation of brightness and chromaticity components of a source image; carrying out the grouping of the brightness and chromaticity components of each row or column of the source image according to the bit level; packaging corresponding groups (4 bits more) according to the values of bits in all groups; packaging the corresponding groups (4 bits lower) according to the distribution condition of numerical values corresponding to bits in the groups; enabling an Ethernet package corresponding to the source image to be placed in a data field of an Ethernet frame in a preset transmission sequence, and enabling the Ethernet frame to be transmitted to the receiving end. According to the embodiment of the invention, the method can improve the transmission efficiency of data, can achieve the lossless transmission of 1080p@60YUV422(16bits) videos.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a high-definition video transmission method and device. Background technique [0002] Ethernet is currently the most widely used LAN technology, and it has largely replaced other LAN standards. Nowadays, Gigabit Ethernet and even 10G Ethernet are continuously expanding the scope of application under the impetus of international organizations and leading enterprises. [0003] For long-distance high-definition image transmission, Ethernet is generally used for transmission at present. The sending end generally uses a dedicated compression chip, and at the same time, the receiving end uses a dedicated decoding chip to compress through standard protocols (such as H.264, H.265 protocols). decoding. [0004] For the transmission of high-definition lossless images of 1080p (a video display format), it is generally limited to the transmission of 1080p30 (30 frames per ...
