Router
Router provides LAN connectivity to all devices. Issues DHCP IP addresses to all devices
on the network.
MPEG2-4
Transcoder
Transcoders change signal from native DIRECTV MPEG4 to MPEG2 for use in RLHD+
systems.
NTSC transcoder
NTSC devices ingest HD digital streams and output 6MHz analog channels.
Encoders
Encoders are used for local channel insertion (LCI). They ingest A/V from a variety of
sources and output ethernet to the QAM or RF to be combined with other video sources.
Pro:Idiom TVs
Pro:Idiom enabled TVs will decrypt Pro:Idiom encrypted HD signals from the COM3000
RLHD+
DIRECTV authorizes some
institutions to use an unencrypted signal. The “Clear HD”
signal is MPEG4. Not all consumer TVs will tune MPEG4 video in which case a transcoder,
or set top box is required
