Switch between SDI & ASI

Epoch | Neutron and Epoch | 4K Neutron developer cards can capture, play through and playout raw transport DVB ASI streams in addition to supporting SDI I/O. Epoch | Neutron offers the flexibility to choose between capturing 2K/HD/SD SDI or ASI and similarly the flexibility to choose to playback either 2K/HD/SD SDI or ASI. Epoch | 4K Neutron offers the flexibility to choose between capturing 4K/2K/HD/SD SDI or ASI and similarly the flexibility to choose to playback either 4K/2K/HD/SD SDI or ASI. That’s maximum transport flexibility for either live or file-based workflows.
