Product Description

3G-SDI HEVC encoder 4K H.264 converter pluggable encoding

With the significant increase in UHD TV hitting the market, this new professional UHD/4K video encoder for a solution to address the needs of early adopters of the premium TV standard. ENC3515 a high-quality UHD H.265 (HEVC) encoder, delivers UHD/4K for an immersive experience with high-resolution and high-framerate. 1RU modular design, it supporting up to 5 pluggable encoding and one output modules, ENC3745 provides a best-of-class encoder platform for Digital TV Owners and TV stations.


The encoder, it can receive and encode four SD/HD/FHD or one 4K into a Transport Stream (TS), combined with its significant HEVC bitrate savings, content in real-time via HEVC (H.265), today’s most advanced compression standard. It is equipped with 3G-SDI interface, built-in Time Base Correction functional block ensures the stability of encoding process from audio and video intermittence.


The ENC3515 encoder employs 4:2:2 10-bit precision encoding technology originally designed for professional transmission. The internal re- multiplexing function allows creation of a new TS formed with the TS internally encoded and the TS from IP input. The final TS can be multiple SPTS or MPTS over IP, as well as over ASI.
