EN91 Ultra Low Delay Encoder
The EN91 is a ultra-low delay MPEG 4 AVC/H.264 high definition encoder. 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.
The lightweight, 10 pound or 4.5 Kilo EN91 offers amazing features and specifications in its 1 RU chassis, including redundant AC power supplies, enhanced control and monitoring via its front-panel, a browser and SNMP; video support includes SD, 2D-HD and 3D AVC 422, sixteen channels of phase aligned audio, robust VBI support, reliability and easy of use all for an extraordinary value. In addition to encoding phase aligned audio, the EN91 pass-through support includes PCM, DolbyE (16 and 20 Bit) and Dolby AC3 (2.0 and 5.1).
The EN91 encodes and concurrently transports services via ASI, IP and DVBS/S2. The DVBS/S2 modulator is available in IF or L-band with modulation modes ranging from QPSK up to 32APSK based on software licenses.
