Transceiver enables multi-channel HD video over 10G Ethernet links

Macnica Americas (San Diego) has released its MAI3140, a silicon transceiver that allows up to 8 channels of high-definition video to be transported over a 10G Ethernet link.

Macnica Americas (San Diego) has released its MAI3140, a silicon transceiver capable of transporting up to 8 channels of SDI video over a standard 10 Gigabit Ethernet (10-GbE) network. The device comes in transmit and receive versions to allow a complete Ethernet link to be implemented. According to the company, forward error correction is added to the transmitted data making the link lossless -- important to prevent dropped video frames and video flickering and / or freezing.

The MAI3140 device accepts video in the form of 3G-SDI, HD-SDI or SD-SDI, encapsulates the video streams in UDP/IP + RTP, adds error correction, and transmits the traffic through a standard XAUI 10-GbE interface. A companion device receives the data, performs any needed error correction and outputs the video streams in the format received. The device is fully compliant with SMPTE2022 clause 1/2 and 5/6 ensuring compatibility with any third party equipment also using the standard. The amount of forward error correction can be varied by increasing the FEC matrix stored in external memory and a per-channel basis.

Applications include broadcast video transport equipment, video switching in studios, remote surgical applications, surveillance and aggregation of multiple HD camera streams to a single storage device or display. The MAI3140 is available immediately. For more information contact Macnica Americas' John Burton at +1 (858) 771-0846 or
