Full Steam Ahead for Haivision's SRT-Optimized HEVC

Full Steam Ahead for Haivision's SRT-Optimized HEVC | Video Breakthroughs | Scoop.it

The first commercial implementations of Haivision's HEVC encoding allied with the company's Secure Reliable Transport (SRT) protocol, are due in the new year.

 

HEVC was perhaps the hottest topic at this year's IBC show in September, but while most demos sought to showcase 4K HEVC in a controlled environment,Haivision took a different tack. The company showed off its HEVC encoding delivered via Haivision's proprietary Secure Reliable Transport (SRT) protocol—sent over the public internet from a hotel close to the conference venue.

SMPTE, VSF announce pair of video-over-IP standards

SMPTE, VSF announce pair of video-over-IP standards | Video Breakthroughs | Scoop.it

The Society of Motion Picture and Television Engineers (SMPTE) and the Video Services Forum (VSF) on Dec. 10 announced the latest two standards in a series that creates a standardized framework for the transport of video-over-Internet-Protocol (IP) networks. 

 

The documents, including the latest additions known officially as SMPTE ST 2022-5:2012 “Forward Error Correction for High Bit Rate Media Transport Over IP Networks” and SMPTE ST 2022-6:2012 “Transport of High Bit Rate Media Signals over IP Networks (HBRMT),” are now available via the SMPTE digital library.

 

SMPTE ST 2022-5:2012 defines a methodology that can be used to provide forward error correction for the recovery from network transmission errors. SMPTE ST 2022-6:2012 defines a uniform data mapping format that supports a wide variety of HD-SDI and 3G-SDI video signal formats.

Brevity's V3 combines multipoint transport and transcoding

Brevity's V3 combines multipoint transport and transcoding | Video Breakthroughs | Scoop.it

When it comes to video, more data translates to better quality. However, the large size of a typical video file in today's HD world also translates into transcode and transfer bottlenecks for broadcasters and production houses. It often becomes a trade-off between preserving quality and resolution versus limiting file sizes or bit rates to meet workflow deadlines.

 

For example, a master file for just one and a half hours of 1080p video could be as large as 540GB. This large file would require many hours to transcode into various formats for editing, broadcasting and archiving purposes. And at 540GB, this digital file would take longer to transfer from one facility to another over the Internet than it would take to ship a physical hard drive across the country overnight. With every project, the workflow comes to a halt as the team waits for files to be transcoded into different formats and then transferred between systems.

 

Brevity, a start-up based in New York City with offices in Los Angeles and Vancouver, WA, is taking a new approach to video transport and transcoding that streamlines the workflow and eliminates the bottlenecks, yet preserves or even improves on quality by avoiding cumulative loss in production and distribution workflows. The Brevity system relies on a combination of licensed software per location and Brevity or third-party certified hardware that has the necessary teraflops of graphical processing power.

 

The service relies on unique algorithms that model and compress information, breaking down a video file into a much smaller “blueprint,” or set of instructions, for rebuilding the file into any format. This computationally intensive GPU-based approach is integrated into Brevity's enterprise video management tool, V3, which provides automated workflows with simultaneous transcode and transfer over a network.

NAB: Brevity Introduces Transport Technology That Transforms File-Based Workflows

NAB: Brevity Introduces Transport Technology That Transforms File-Based Workflows | Video Breakthroughs | Scoop.it

Brevity announced at the NAB convention today V3, a technology that delivers simultaneous transcoding and accelerated transport of high-resolution video as an integrated process on any network.

 

V3 delivers its transport capabilities through a Web-based enterprise video management solution that utilizes automated project-driven workflows, advanced algorithms, virtual storage, Web-based interfaces, and teraflops of computing power. The technology moves securely encrypted files over Internet, fiber, or data satellite up to 30 times faster than otherwise possible, while maintaining high quality resolution and support for leading industry codecs and formats such as Avid DNxHD, EVS MXF, Final Cut Pro, Sony camera formats, and others. Brevity says that V3 has been tested successfully on uncompressed, high bit rate video, 2k and 4k DPX files, as well as on compressed HD and SD files.

Open Source DPP creation

Open Source DPP creation | Video Breakthroughs | Scoop.it

From time to time we work on other things beyond DVB broadcast encoding where Open Source can be used to transform closed broadcast workflows. The file delivery specification from the Digital Production Partnership (DPP) is one such area. However, the AVC-Intra codec used in DPP is effectively a proprietary codec with implementation in the real world being more complex than the SMPTE RP2027 that AS-11 recommends and in a number of areas implemented incorrectly. However, we have now successfully reverse engineered AVC-Intra from available samples which allows a fully open source DPP creation workflow. Along with existing Open Source projects for manipulation and creation of mxf files, a fully compliant DPP file can be delivered to UK broadcasters.

TranSPORT: HEVC, JPEG 2000 Could Build Bridge to Future of Video

TranSPORT: HEVC, JPEG 2000 Could Build Bridge to Future of Video | Video Breakthroughs | Scoop.it

The world of sports-video contribution, backhaul, and distribution looks to be on the brink of a major leap forward. New technologies like HEVC (high-efficiency video coding) are set to enter the market, and others, particularly JPEG 2000, continue to carve out a larger share of it. Compression standards and formats like these hold the promise of paving the way for the delivery of next-gen formats like 1080p, 4K, and 8K.

 

An afternoon session moderated by CBS Director of Broadcast Distribution Chris Ehrenbard at SVG’s TranSPORT in New York on Tuesday focused on the evolution of these bleeding-edge technologies and their place in the sports-video landscape.

BBC R&D embeds Xilinx FPGAs into New Stagebox Camera-Back Mount to Support Transmission of Video Over IP

BBC R&D embeds Xilinx FPGAs into New Stagebox Camera-Back Mount to Support Transmission of Video Over IP | Video Breakthroughs | Scoop.it

BBC R&D and Xilinx, Inc. have demonstrated a prototype camera-back device (Stagebox) at the National Association of Broadcasters Show (NAB) that enables the transport of professional quality video over internet protocol (IP)-based networks. The BBC R&D Stagebox can be attached to the back of any broadcast-quality camera. Due to the integration of more system functionality onto a Xilinx field programmable gate array (FPGA), expensive and cumbersome SDI/audio/talkback and ancillary cabling can be replaced with a single network cable (fiber or Cat6). The small form factor device effectively expands the reach of video networks to remote production sites and studios using IP networks.
