SIOUX FALLS, S.D.—Sencore has unveiled its Sencore TXS 3800 transcoder appliance that converts multiple ATSC 3.0 services into ATSC 1.0-like formats for reuse and retransmission by existing cable TV, TV translator and MVPD systems.

A dense terrestrial transcoder, the TXS 3800 can transcode up to four ATSC 3.0 services in a single chassis, Sencore said.

Video features include MPEG-2 and H.264 compression, along with downscaling, transrating and caption conversion. Audio is transcoded to either AC-3 or AAC, and service names are mapped into standard TVCT format, it said.

Once transcoded, all elements are packaged into an MPEG transport stream and output as traditional MPEG/IP for downstream use.

The TXS 3800 seamlessly integrates ATSC 3.0 signals into existing signal paths with minimal impact on architecture and processes, the company said.

The new product is backed by Sencore’s ProCare support engineers.

More information is available on the company’s website.

SUNNYVALE, CALIF.—Vitec has unveiled the latest version of its IPTV transcoding platform, the MGW Prism. The new version adds HEVC (H.265) transcoding and a redesigned management interface with clustering support.

MGW Prism

The MGW Prism is able to transcode video streams to H.264 or HEVC SD/HD streams for delivery to CDNs, remote locations, or other IPTV viewers using less bandwidth. The system can also generate up to 16 profiles per video source and a combiner for generating adaptive bit rate streams using containers like Apple HTTP Live Streaming, Adobe HTTP Dynamic Streaming, and MPEG-DASH without having to offload to external servers.

The Prism also features KLV 0601/STANAG 4609 metadata pass-through, which allows satellite companies to ingest IP streams from airborne vehicles and relay them with lower bit rates using H.265 or H.264, while retaining metadata on the output stream.

VITEC, a provider of video encoding and streaming technology, demonstrated the new MGW Prism at IBC 2015.
