- Ten optimized hardware pipes (5x Rx, 5x Tx), designed for superior performance.
- Intuitive AV FIFO API, purpose-built to streamline and simplify IP streaming tasks.
- SFP+ slot for 25G and 10G modules, catering for both electrical and optical connections.
Applications
-
Ideal for new software-based SMPTE 2110 solutions, and for modernizing
applications that previously used SDI for SMPTE 2110:
- Software encoders, decoders, transcoders
- Playout and live production mixers
- Monitoring and multiviewer systems
- All kind of recording solutions
- Adaptable to your unique needs
- The DTA-2125 makes such transitions easy, ensuring efficiency and performance.
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.
