Technology Overview

VSS is a leading provider of video and audio compression technology. As broadcasting and communications technologies evolve, new audio/video compression standards immerge, VSS has consistently been the first to develop commercial real-time H.264 encoder technology for the Pentium architecture.

VSS continues to provide the highest quality and performance in H.264; AAC and now HEVC compression technologies. In the past 3 years VSS has expanded its implementations to include PC, ARM, FPGA and DSP architectures. VSS implementations focus on applications in broadcast, web streaming (OTT), Video Communications, and Video Publishing markets.

VSS Core Technology Overview

• Patented and patent-pending video compression algorithms, including for motion estimation, deblocking, scalability, noise suppression, wavelet transforms, rate control
• Software architecture designed for performance
• Best quality in tight real-time constraints
• Encoder engine achieves best quality-performance balance on PC and embedded architectures
• Hardware acceleration IP core designs for AVC-Intra and CABAC processing
• Highly modular ThruCode™ codebase architecture allows easy software maintenance, upgrades, and quick portability to new platforms. This flexibility has led to:
• "smart" transcoders by simple integration with other codecs like H.263 and MPEG-2
• high quality H.264<->H.264 smart transraters and transcoders
• integration of codec engine with external prediction modules (for example, FPGA-based inter and intra search engines)
• high quality real-time control to precisely regulate decision quality (and therefore output video quality) depending on available CPU clocks
• VSS ParallelStream is an H.264/AVC patent pending implementation of single video stream transcoding to many GOP aligned streams
  • Up to 8 different streams encoded in a single pass, from single input
  • Up to 50% more efficient Transcoding then traditional multi-pass methods.
