Abstract

The invention discloses an optical fiber self-healing ring network video encoder which adopts an optical fiber self-healing ring network technology. The video encoder comprises a video input module, a video compression encoding module and an optical fiber self-healing ring network module, wherein the video input module is used for inputting an analog video and carrying out A/D conversion; the video compression encoding module is used for carrying out compression encoding for the video obtained from the video input module and encapsulating the video into an IP packet signal; the optical fiber self-healing ring network module is used for receiving the IP packet signal sent by the video compression encoding module and finishing the self-healing ring network optical fiber access of the IP packet signal; and the output end of the video input module is connected with the input end of the video compression encoding module, and the output end of the video compression encoding module is connected with the input end of the optical fiber self-healing ring network module. The optical fiber self-healing ring network video encoder is adapted to the long-distance high-reliability networking transmission and control requirements of a large-scale high-definition encoder and has the functions of Ethernet access and long-distance image transmission through an optical fiber.

Description

technical field [0001] The invention relates to a video encoder, in particular to an optical fiber self-healing ring network video encoder using optical fiber self-healing ring network technology. Background technique [0002] There are two main types of existing video compression encoders: one is E1 video encoder, and the other is IP video encoder. The E1 video encoder converts the compressed video stream into E1 signal for long-distance transmission; the IP video encoder encapsulates the compressed video stream into IP packets, and communicates with the external Ethernet through the i0M / 100M Ethernet port Connect and then transmit over long distances via Ethernet. [0003] Whether it is an E1 video encoder or an IP video encoder, they all need an external network (E1 transmission network or IP network) for transmission. Therefore, these encoders need to install additional transmission equipment behind the encoder, which makes the system equipment and management more comp...
