H.264, also known as MPEG-4 AVC (Advanced Video Coding), is a video compression standard that offers significantly greater compression than its predecessors. The standard is expected to offer up to twice the compression of the current MPEG-4 ASP (Advanced Simple Profile), in addition to improvements in perceptual quality. The H.264 standard can provide DVD-quality video at under 1 Mbps, and is considered promising for full-motion video over wireless, satellite, and ADSL Internet connections.

DVR USA Technologies utilizes the latest industry standard (ISO/ITU) video compression technology known as H.264. H.264 use s a fully optimized algorithm based on Digital Signal Processor ( DSP ) technology. Display and recording of video and audio are in real-time and fully synchronized in both modes. Video feeds are directly transmitted from the video capture card to the display frame buffer and the compressed stream data is directly sent to the host's memory. The transmission process doesn't need any intervention from the host computer's CPU, greatly saving resources of the host computers processor. The result is flawless images and sound regardless of how many channels being monitored or reviewed.

Compared to the prior generation MPEG4 and MPEG2 technologies, the H.264 video quality is significantly better. Despite the higher quality enhanced video the h.264 file size is 25% smaller than MPEG4, 50% smaller than MPEG2 and exponentially smaller than MJPEG.

As opposed to the 10 year old MPEG2 and 7 year old MPEG4 standards the H.264 codec used by DVR USA was designed with security in mind. So read on and experience the power of H.264. Seeing and hearing truly is believing.

*2x more efficient than MPEG-4 Part 2 (natural video) encoding:

*3x smaller file size than comparable MPEG-2 encoders:

*Faster download time:

*Substantially higher quality video (SNR)

*No fast motion blurring inherent in MPEG-4 (advanced motion compensation)

H.264 offers dramatically lower bit rates and better picture quality than MPEG-2, MPEG-4, H.263+ etc.
