- Custom AV-over-IP applications tailored to your needs
Block Diagram
Outlined below is the block diagram of the DTA-2125's firmware, organized into two pathways: transmission (upper section) and reception (lower section).
The transmission path incorporate three hardware pipes that directly interface with the user application, resulting in excellent performance. Packets from these hardware pipes are multiplexed with those from the software pipes and the standard network stack. A scheduler ensures that each packet is transmitted precisely according to its PTP timestamp.
Conversely, the receive path also integrates 5 hardware pipes directly interfaced with the user application. All remaining packets are dispatched to a software router. This router channels real-time AV streams to the software pipes, while normal standard network traffic is forwarded to the conventional network stack.
