how does the first mentioned communication channel take place?
HDMI specifically requires the device implement the E-DDC, which is used by the HDMI source device to read the E-EDID data from the HDMI sink device to learn what audio/video formats it can take.

HDMI specifically requires the device implement the Enhanced Display Data Channel (E-DDC), which is used by the HDMI source device to read the E-EDID data from the HDMI sink device to learn what audio/video formats it can take. HDMI requires that the E-DDC implement I²C standard mode speed (100 kbit/s) and allows it to optionally implement fast mode speed (400 kbit/s).
when did high speed hdmi cables come out The development started on April 16, 2002. what is the full form of this abbreviation? High-Definition Multimedia Interface what is the function of this cable? It is used for transmitting uncompressed video data and compressed or uncompressed digital audio data from an HDMI-compliant source device, such as a display controller, to a compatible computer monitor, video projector, digital television, or digital audio device. who all were involved in the development of this mentioned interface? The founders were Hitachi, Panasonic, Philips, Silicon Image, Sony, Thomson, RCA, and Toshiba. what are some of the communication channels of this interface? It has three physically separate communication channels, which are the DDC, TMDS and the optional CEC.

HDMI [SEP] Display Data Channel (DDC)
The Display Data Channel (DDC) is a communication channel based on the I²C bus specification. HDMI specifically requires the device implement the Enhanced Display Data Channel (E-DDC), which is used by the HDMI source device to read the E-EDID data from the HDMI sink device to learn what audio/video formats it can take. HDMI requires that the E-DDC implement I²C standard mode speed (100 kbit/s) and allows it to optionally implement fast mode speed (400 kbit/s). The DDC channel is actively used for High-bandwidth Digital Content Protection (HDCP).
