Abstract
An apparatus and a method for providing serialized HDMI data from an HDMI source to an HDMI sink. An HDMI transmitter may include inputs including control inputs, a deserializer, and a parser. The inputs may receive serialized HDMI data from an HDMI data source. A deserializer may deserialize the serialized HDMI data received on each of the respective inputs and outputting parallel data for each of the inputs. A parser may parse the parallel data output from the deserializer from each of the respective inputs into serial video data at a first clock rate and audio data at a second clock rate. Control inputs of the transmitter may be set to a first mode in which from the deserializer is caused to bypass the parser, and the parallel data is output from the HDMI transmitter.
