QV codecs were especially designed for the purpose of transporting video/audio signals via any IP networks, including wireless networks and the public Internet.
The QV codecs have proprietary patented advanced Error Correction – ARQ (Automatic Retransmission Request).
It is a dynamically adjusting feedback error correction mechanism designed specifically to enable the highest quality video transport over unconditional IP networks, including wireless networks and the public Internet.
ARQ detects packet loss at the receiver (decoder) and requests the retransmission of only those lost packets from the transmitter (encoder). A user-configurable buffer at the decoder delays the video stream just long enough to allow the system to replace any missing packets and re-insert them in their proper order without disturbing play out of the video stream.
Because ARQ senses actual packet loss, rather than attempt to predict packet loss (as FEC does), it can precisely and completely restore all lost packets without disturbing timing of the video play out. ARQ can provide nearly flawless reproduction of a video stream even through extremely lossy or congested networks. This allows sending and receiving video/audio over nearly any IP network and across the world, including the public Internet.
A140-ARQ is Amino A140 IPTV set-top box with preloaded ARQ software.
This software allows A140 to work with QV encoders in ARQ mode.
