Barco Silex Integrates New Video Coding Technique from the Latest VC-2 HQ Standard

Barco Silex, leading provider of video compression technology and OEM solutions in the broadcast and pro A/V market, has announced an upgraded version of its VC-2 HQ codec for high quality broadcast applications.

This new version of our implementation of the codec is completely in-line with the recent update of VC-2 HQ open standard (SMPTE ST 2042-1:2017).

The VC-2 HQ codec is a high quality codec for professional applications. Its primary use is the light compression of high pixel rate video (4K, 8K) content to lower bandwidth in order to ease the real-time transport over networked IP infrastructure. The VC-2 HQ compression is essentially visually lossless, and does not add any noticeable latency to the system which is important for applications such as broadcast contribution.

Our new implementation of the VC-2 standard is compliant with the latest version of the SMPTE standard. The latest revision (SMPTE ST 2042-1:2017), released in June 2017, introduced the option of using asymmetrical wavelet transform for the VC-2 processing, instead of the usual symmetrical wavelet. Asymmetrical wavelets allow a better trade-off between the complexity of the codec and its efficiency. The new standard has also been updated to support latest and future video formats.

In order to provide our customers with a state of the art lightweight codec for ASIC and FPGA, we decided to upgrade our VC-2 HQ IP cores to support the asymmetrical wavelet filtering according to the standard. Our implementation uses the LeGall filter with 5 horizontal levels and 1 vertical level, guaranteeing a compression without artefacts with very low FPGA/ASIC area.

In the broadcast industry, it is important to develop systems around open standards in order to reach interoperability between the different vendors. The new version of the VC-2 standard enables manufacturers of video over IP equipment’s to benefit from the latest coding techniques. Barco Silex will demonstrate its VC-2 HQ codec at IBC show in Amsterdam, booth 10.D31.
