BE8700 Multi-Channel HD/SD Encoders

The Telairity BE8700 multichannel system (available in configurations of 1 to 4 channels) is a scalable, fully programmable broadcast quality encoder for high and standard definition video formats; able to autosense input type and select a corresponding HD/SD encoding mode automatically. Telairity’s uniquely powerful technology generates leading-edge H.264/AVC video compression to achieve industry-leading video quality at very low bit rates for maximum transmission and storage efficiency. The 1RU BE8700 multi-channel platform also minimizes rack space to further reduce per-channel costs. The BE8700 can be readily upgraded via a software download to add new features or enhance performance. image
