The ARG 8000 ARQ can ingest ASI or IP transport streams and adds advanced Automatic Retransmission Request (ARQ) and intelligent buffer management to establish a high quality of service between multiple locations suffering from packet loss and poor jitter performance. Each ARG 8000 is supplied with one transmitter (TX) or receive (RX) license and can support multiple TX and or RX licenses per unit. Each license enables one transport stream (TS) to be broadcast/ received with ARQ.
Being scalable in single stream increments, broadcasters can quickly add extra ARQ licenses to deliver multiple IP UDP unicast and multicast services.
The ARG ARQ TX license takes a standard TS from any encoder as ASI or IP and adds additional overhead to a standard UDP IP Packet which is sent onto the ARG ARQ RX. The RX uses this additional overhead to check the integrity of the stream. Any jitter, out of order packets, corrupt packets or lost packets will be re-established with packet resends and intelligent buffer management. All packets sent between TX and RX ARQ units are UDP. At each TX and RX site a single configurable UDP port per TS will need to be open for normal operation. All management is http on port 80.
