Video serializer/deserializer with embedded audio support

A video serializer fabricated on a single integrated circuit, comprising:

• an audio core that receives a parallel video input signal having ancillary space, an audio data input signal, and one or more configuration signals, and that embeds the audio data input signal into a location within the ancillary space of the parallel video input signal to generate a parallel video signal with embedded audio, wherein the configuration signals are processed by the audio core to identify the location within the ancillary space of the parallel video input signal;
• a video core coupled to the audio core that receives the parallel video signal with embedded audio from the audio core and receives a video clock signal, and that converts the parallel video signal with embedded audio into a serial video signal and synchronizes the serial video signal with the video clock signal to generate a reclocked serial video signal;
• and
• a cable driver coupled to the video core that receives the reclocked serial video signal from the video core and receives one or more configuration signals, wherein the configuration signals are processed by the cable driver to generate a serial video output signal from the reclocked serial video signal that complies with a pre-selected video standard.

A method of automatically extracting audio data from a serial video signal of an unknown video standard, comprising the steps of:

• receiving a serial video signal having embedded audio data;
• converting the serial video signal into a parallel video signal;
• automatically decoding the parallel video signal to identify a unique characteristic associated with a particular video standard;
• automatically identifying a video formatting scheme based on the particular video standard;
• automatically identifying a location of embedded audio data within the parallel video signal based on the identified video formatting scheme;
• and
• extracting the embedded audio data from the parallel video signal using the identified location.

A video deserializer, comprising:

• a video core that receives a serial video signal and converts the serial video signal into a parallel video signal;
• a clock generator that generates an audio clock signal as a function of a known reference clock signal;
• and
• an audio core coupled to the video core and the clock generator that receives the parallel video signal from the video core and receives the audio clock signal from the clock generator, wherein the audio core locates and extracts audio data from within ancillary space of the parallel video signal and synchronizes the extracted audio data with the audio clock signal to generate an audio output signal;
• wherein the video deserializer is fabricated on a single integrated circuit.
