Product Description

ENC3445 has proven itself as the most advanced encoding platform for DVB-C QAM Cable, USA ATSC Off Air, DVB-T, DVB-C, DMBT, ISDB-T Clear Modulation applications available today. The hardware platform has been widely deployed for MPEG-2 and MPEG-4 AVC HD broadcasting applications with Low latency and D Digital AC-3 Audio, closed captioning and redundant AC power supplies support.

ENC3445 supports the most demanding video applications. It offers codec and transport flexibility, interoperability and feature richness, and equipped with 4 channels HD MI or HD-SDI inputs and multiple codec standard (MPEG-2 and MPEG-4 AVC/H.264 video encoding and MPEG1 Layer II, HE-AAC, LC-AAC, D AC3 audio encoding). It provides ultra-high quality video for your contribution workflows, IP as well as the DVB ASI output that meets MPEG-TS stream standard. The product is ideal for a broad range of applications including contribution and distribution.
