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...

Problems solved by technology

Therefore, these encoders need to install additional transmission equipment behind the encoder, which makes the system equipment and management more complicated

In addition, sometimes an independent external IP network is difficult to guarantee the reliability of the network. For example, when a point-to-point fiber optic transceiver is used for transmission, when the fiber is broken, the network will be paralyzed
