2.3 Configuring Packet Transport & Error Correction
The QVidium H.264 SD Video Codec™ features some of the most powerful and advanced error
correction capabilities found in any video over IP product. The QVidium H.264 SD Video Codec™
implements QVidium ‟s patented ARQ error correction and clock synchronization (US Patents
#7,551,647 and #7,522,528) for the more robust video transmission with the lowest delay.
QVidium‟s ARQ (Automatic Retransmission Request) is a dynamically adjusting feedback error
correction mechanism designed specifically to enable the highest quality video transport over
wireless networks and the Internet. ARQ senses packet loss at the receiver and requests
replacement packets from the server. ARQ can provide nearly flawless reproduction of a video
stream even through extremely lossy or congested networks.
The QVSD H.264 SD Video
Codec™ minimizes network bandwidth and loading due to its
extremely efficient encoding and video transport. The SD Video Codec™ implements MPEG4-AVC
(H.264) High Profile (Levels 4 and 4.1) video encoding, providing advanced coding techniques in
hardware, such as CABAC processing, not normally found in other MPEG4 codecs. Our codec
