A DEVICE FOR RECEIVING OF HIGH-DEFINITION VIDEO SIGNAL WITH LOW-LATENCY TRANSMISSION OVER AN ASYNCHRONOUS PACKET NETWORK

摘要

A device based on the proposed solution allows high-definition video transmissions with low latency over an asynchronous packet computer network such as Ethernet. The transmitter and receiver comprise a video input or output module (1), an FPGA board (3), and an optical transceiver (5) for transmission and reception of a signal over the Ethernet network. The principle of the new device is that the receiver comprises one or more tunable oscillators (9) connected to the FPGA board (3) comprising a module (7) for packet reception, and one or more sets (4) of modules for video data processing. These sets (4) of modules adjust the data rate onto video outputs (2) to the data generation rate on the transmitter's side and enable to display the beginning of a frame at the correct position, even though the transmitter and receiver are interconnected by an asynchronous packet network such as Ethernet, which cannot be used for receiver clock recovery in line with a transmission data rate, and this is all possible without the need for a large frame memory increasing the delay.
