Blonder Tongue In STEP with Video-Over-IP at NAB

Blonder Tongue Laboratories will launch a new Scalable Transcoder-Encoder Platform (STEP) at NAB 2015. STEP will provide broadcasters a cost-effective approach to video-over-IP distribution.

“Broadcasters need cost-effective, versatile solutions in order to adapt to today’s fast-paced and competitive environment,” said Walt Davis, senior director of product management and technical services at Blonder Tongue. “STEP features a flexible software architecture that allows users to overcome the technical challenges of multivendor products, constantly changing design requirements, and the introduction of new standards. By providing superior-quality encoding, transcoding, downscaling, and streaming functionality, all in a single software-based package, STEP makes video-over-IP distribution affordable, scalable, and easy.”

STEP is capable of HD/SD MPEG-2 or H.264 encoding; HD/SD MPEG-2 to H.264 and H.264 to MPEG-2 transcoding; HD to SD downscaling as well as creating adaptive bit rate live profiles supporting HTTP streaming protocols such as HLS, HDS, and IIS. 


Available as a 1RU, 2RU, or 3RU integrated system, the platform supports multiple video quality encoding bit rates, multiple audio formats, and text scrolling. In addition, STEP is compatible with any industry media server or digital rights management software, and can be easily integrated into CDN providers, offering users a tailored solution based on customer needs.

At the heart of STEP are three separate components: a splitter block capable of splitting incoming ASI- or IP-based MPEG-2-TS streams and rerouting them, or the individual programs, into a multiprogram transport stream (MPTS); a media processing engine that provides comprehensive video and audio processing functions required for applications such as decoding, encoding, transcoding, and format conversion as well as AES scrambling and logo insertion; and a mux functionality that can pass through and/or merge single program transport streams (SPTS) into an MPTS.

STEP’s low-latency MPEG-2/H.264 encoder utilizes multicore video encoding technology to perform real-time transmission of content at low bit rates over broadband IP networks. The encoder also supports on-screen text scrolling for a variety of applications including advertising, company logos, symbols, and stock tickers. In addition, the STEP solution supports various input options including analog baseband, VSB, and clear QAM programs, as well as a PIP output and Pro-MPEG CoP3 forward error correction.
