IPTV STB (SD / MPEG2) -zapper

Our company is broadband provider and for our (already deployed) IPTV service we need
an IPTV STB for low cost and/or multiroom service (SD / MPEG2).

The only service that the box must do is zapping between multicast channels.

Specification:
- inputs: fast ethernet for network connectivity,
- outputs: EURO/SCART and/or S-Video with EURO/SCART compatible cable,
- codec: MPEG2 transport stream,
- optionally: USB.

Software functionality:
- DHCP support,
- must enable operator to set channellist (via TFTP or via DHCP config)
- SDK should be provided or vendor should declare to integrate with software CAS
provider (Latens / Verimatrix),
- decoding of multicast MPEG2/TS reception (live channels),
- decoding of unicast RTSP MPEG2/TS (vod) would be a plus.
