Wireless Connection (Circuit Explanation)

The signal is wirelessly transmitted in 2 different frequencies.
The video and audio signal are converted to TMDS (Transition Minimized Differential Signaling) in
the DH board of the Tuner Box.
The TMDS data is converted to RF signal and is transmitted as a 60GHz RF signal from the WT
circuit in the WiHD transmitter module.
The control CEC signal is transmitted at 2.4GHz by the RF module (RM) in the transmitter unit.
The RF signals from the transmitter are picked up by the (2.4GHz and 60GHz) RF IF modules in
the receiver unit.
The 60GHz signal from the transmitter is decoded to TMDS format and DDC-IIC.
The CEC, TMDS, and DDC-IIC are connected to the HDMI In (GH) board in the Display Unit.
The TMDS data and the DDC-IIC are provided to an Equalizer circuit in the GH board to
compensate for signal decay and degradation due to cables and connectors.
CEC enables the Tuner Box and the Display Unit to control each other. CEC stands for Consumer
Electronics Control.
CEC, a one-wire bidirectional line allows he Tuner and the Display to share a communication
channel.
The TMDS data and the DDC-IIC are applied to IC24510 for processing.
The video signal and the audio signal are separated in IC24510.
