SMAC-M is specially designed for TeleEye RX Series Video Recording Transmitters. It is a multi-rate vector quantization based video coder that output 5 independent digital video streams at different bit rates to cover all commercial communication channels in the market.
The first video stream of an SMAC-M coder is reserved for real-time video recording. The other 4 video streams are designed for efficient transmission through LAN, broadband Internet, phone line and mobile channels. The separate data streams for recording & transmission lead to optimum performance on both aspects. The independent video streams also ensure that the recording performance will not be affected by remote surveillance through bursty channels.
Dr. Cliff Chan, CEO of the Group said, "We compared several DVRs using various compression technologies in terms of recording and remote surveillance performances. For the same HDD, TeleEye RX Series incorporated with SMAC-M can record 40% more days than MPEG-4 and 4 times more than MJPEG or JPEG2000 at the same picture resolution, quality and frame rate. For transmission, SMAC-M is about 50% faster than MPEG-4 under ADSL environment. The TeleEye RX DVR using SMAC-M technology can achieve high quality video recording and efficient remote video surveillance at the same time."
The SMAC-M shows superior compression performance than standard MPEG compression techniques. The resulting TeleEye RX series of DVR outperforms all other DVRs in terms of recording duration and video transmission efficiency. The SMAC-M video coding technology places TeleEye at leading edge of remote surveillance and recording technology.
