SigmaTel chip provides video function for PMP

SigmaTel is changing the way portable entertainment lets users convert ordinary PC video files into formats that can be played on portable multimedia players (PMPs). SigmaTel's Active Video (SMV) technology is provided as an extension of the SigmaTel STMP3500 Software Development Kit (SDK).

The key to SigmaTel's latest technology is its ability to compress video at higher speeds while maintaining a relatively high frame rate and resolution. This function has been applied to its products by leading manufacturers in the PMP market including Zhongyu, Jinghua, ACE, Songri and Meizu.

Ron Edgerton, President and CEO of SigmaTel, said: "Today, entertainment means a full-featured multimedia experience that people want to enjoy anywhere, anytime, whether in a car, bus, plane, or train. SigmaTel's portable multimedia semiconductor solutions enable manufacturers to create new designs that take PMP's performance to the next level – with a new player that can play music TV or TV with the touch of a button program."

SigmaTel's SDK also includes PC code conversion software that converts ordinary PC video files into SMV file format. Frame image processing can be implemented during the transcoding process, and the style or logo coverage of the video speech can also be applied to the generated file. Using a proprietary active video file format, SigmaTel's portable multimedia solutions enable 128x128 resolution at 10 frames per second (fps) or resolution at 15 frames per second (fps) The rate is 96x64 video. A regular 128 MB SMV file can store up to an hour of video content, and if you choose a higher compression ratio, you can also store longer video files.
