Video Insight Now Supports WMV9 Compression

Video Insight now supports Microsoft high performance Windows Media Video (WMV) as a compression option for recording and streaming surveillance video. WMV is a cutting-edge codec that offers very high image quality with excellent compression efficiency. The quality of the reconstructed content that WMV produces has been deemed superior to competing video compression standards in independent tests (1). At the same time, it can encode content with up to three times the compression efficiency of MPEG-2. WMV is also capable of delivering high-definition video at bit rates as low as 6 to 8 Mbps.

The WMV9 format allows Video Insight to archive longer on the same disk space, and requires less bandwidth to transmit over a network. This means WMV can save you money by reducing your storage and network bandwidth costs. You can also adjust the quality of the recording using 5 levels of quality definition. WMV compression is stored in industry standard AVI formats and can be played back on a variety of devices.

About Windows Media Video 9 Series Codecs

VC-1 is a video codec specification that has been standardized by the Society of Motion Picture and Television Engineers (SMPTE) and implemented by Microsoft as Windows Media Video (WMV) 9. Formal standardization of VC-1 represents the culmination of years of technical scrutiny by over 75 companies, leading to a codec that is well-documented, extremely stable, easily licensable, and accepted by the industry.

The emphasis during development on reducing the computational power required by the VC-1 decoder provides advantages for a broad range of media consumers. Personal computer users can decode full 1080i/p resolution video with off-the-shelf hardware, making HD video delivery a reality for the home computer. Perhaps more important than the benefits of VC-1 to the personal computer market is its value in the consumer electronics space. Hardware supporting VC-1 includes next generation DVD players, set-top boxes, portable media devices, wireless phones, and more. Major industry players are selecting VC-1 for its scalability and quality.

VC-1 is leading the next wave of digital video. It is a high-quality codec that benefits from the resources of Microsoft® while being an open standard. Adopters can choose to develop custom implementations and solutions or to use the existing support provided by Windows Media technologies. VC-1 offers something for every digital video solution.
