EN91 HD Video Encoder

The Adtec commercial broadcast quality EN91 is an industry leading high definition video encoder that provides ultra-low delay MPEG 4 AVC/H.264 high definition encoding for professional content distribution and delivery applications. The ultra-low delay mode requires the use of Adtec’s RD60 IRD and delivers picture-to-picture services in 100 milliseconds; The EN91 standard delay mode is fully interoperable with other IRDs making it ideal for mission critical trunking and ad-hoc applications. MPEG 4 AVC/H.264 is significantly more efficient than JPEG making it the CODEC of choice for multiplexed and bandwidth sensitive applications; AVCs inherent interoperability significantly adds to the value of solutions based on this industry standard.
