Hi Linux media folks,
We are considering putting an advanced HDMI receiver chip on our SoC,
to allow reception of HDMI audio and video. The chip receives HDMI data
from a host like a set-up box or DVD player. It provides a video data interface
and SPDIF/I2S audio data interface.
We plan to
this issue.
Do we require a Audio-Video Bridge kind of utility/mechanism?
