HDCP
Terra devices fully support HDCP.
Color-space Conversion
When in Genlock mode, the RX outputs the HDMI video in the exact same format as received by the
TX connected to the source.
But when the RX is in any other mode (processing mode) the RX output is always in 8-bit RGB color
space.
Chroma resampling is available for YUV 422 and YUV 420 source to RGB as well as conversion of both
10- and 12-bit sources into 8 bit.
HDMI Audio Routing
•
By default, HDMI audio follows the HDMI video; if video is routed from TX 1 to RX 1, the audio
follows automatically.
•
If the RX unit is in Genlock mode, then the audio that follows the video is unchanged
regardless of the audio format (LPCM, Dolby, DTS, Stereo, and Surround).
•
If the RX unit is receiving, both the original multichannel (up to 8 channels) audio and
downmixed 2-channel (stereo) is to the RX.
•
If the HDMI audio received from the source is in LPCM format, it is possible to locally breakout
the audio as downmixed 2-channel and output it as ancillary audio stream.
•
An RX receiving HDMI audio can embed the audio into the HDMI output signal or output the 2-
channel downmixed audio as 2-channel ancillary audio.
IR Control
IR control has two modes:
•
Transport mode: IR signals are transported between end devices; from any end device RX or
TX to any other RX or TX device. Once the routing is configured, any IR signal received from
an infrared remote by the IR receiver on the transmitting device comes from the IR
transmitter on the receiver device.
•
Injection mode: IR data is injected into the Transmitters and Receivers system through the
control layer. The IR data is routed from the control layer to the target end point where it is
sent out as IR signal using the IR transmitter embedded into the end device to turn on. The
opposite is also true. It is possible to route IR data received by Transmitters and Receivers
end point to the control layer.
In Transport mode the IR output carrier frequency is not necessarily the same as the IR input carrier
frequency. The IR receiver will strip the carrier before it is transported and then the IR transmitter will
add a fixed 38 KHz signal carrier.
