Adtec Digital’s ultra-low delay endoder/modulator

Primary markets for the EN-91 includes DSNG, SD, HD and 3D contribution, distribution and fixed circuit trunking.

Adtec Digital has launched a high definition DSNG/contribution encoder/modulator, and multi-CODEC ultra-low, low and normal delay MPEG 2 and MPEG 4 AVC/H.264 high definition IRD. Primary markets for the EN-91 include DSNG, SD, HD and 3D contribution, distribution and fixed circuit trunking.

“Our EN-91 ultra-low delay DSNG contribution encoder/modulator can send contribution quality HD video around the globe using IP based networks, ASI Fibre, or DVBS/S2 satellite delivery,” stated Kevin Ancelin, senior vice president of sales for Adtec Digital. This device reportedly combines high-efficiency AVC 4:2:2 compression with processing for flexible delivery of video for time sensitive and bandwidth-limited applications. “Paired with Adtec’s RD-60 IRD, the EN-91 can deliver HD Video and sixteen channels of audio with an end-to-end latency under 100 milliseconds,” he added.

The EN-91, according to the manufacturer, supports high definition and standard definition MPEG 4 AVC/H.264 video with 4:2:0 and 4:2:2 Chroma sampling, boasting up to eight pairs of audio, VANC/HANC VBI pass-through and more as standard features. “Why choose JPEG?” asked Ancelin. “It is an indisputable fact that AVC 4:2:2 is far more efficient than JPEG based CODEC’s, regardless of your platform, DSNG Satellite, ASI Fibre or IP delivery. Adtec’s proven compression and decoding solutions are the choice for broadcast professionals globally.”

The EN-91, AVC 4:2:2 and RD-60 receiver can deliver HD-SDI with end-to-end delays of only 100 milliseconds with no dedicated fibre link needed like Motion JPEG. Both the EN-91 and RD-60 are fully interoperable with leading third-party receivers and encoders. Standards included are redundant power supplies, SNMP control and monitoring, an intuitive web control interface, and a push-button front panel interface.

“For price, performance and operator ease of use you will not find a better solution,” added Michael Armstrong, sales manager at Adtec Digital.
