Component Processor - Analog Devices Advantiv ADV7604 Hardware Manual

ADV7604
With the inclusion of HDCP, displays can receive encrypted video content. The HDMI interface of
the ADV7604 allows for authentication of a video receiver, decryption of encoded data at the
receiver, and renewability of that authentication during transmission, as specified by the HDCP
v1.3b protocol.
The HDMI receiver offers audio functionality. The receiver contains an audio mute controller, which
can detect a variety of conditions that could result in audible extraneous noise in the audio output.
Upon detection of these conditions, the audio data can be muted to prevent audio clicks or pops.

Component Processor

The CP section is capable of decoding a wide range of component video formats in any color space.
Component video standards supported by the CP are 525i, 625i, 525p, 625p, 720p, 1080i, 1080p,
1250i, VGA up to UXGA at 60 Hz, and many other standards.
Two fully programmable any-to-any 3 × 3 color space conversion matrices are placed in the front
end and the back end of the CP section. Either of the two color space converters can be used to
implement YPrPb to RGB and RGB to YCrCb conversions. Many other standards of color space can
be implemented using the color space converter.
The output section of the CP is highly flexible. It can be configured in Single Data Rate (SDR) mode
with one data packet per clock cycle or in a Double Data Rate (DDR) mode where data is presented
on the rising and falling edge of the clock. In SDR mode, a 16/20/24-bit 4:2:2 or 24/30/36-bit 4:4:4
output is possible. In these modes, HSync, VSync/FIELD, and FIELD/DE (where applicable) timing
reference signals are provided. In DDR mode, the ADV7604 can be configured in an 8/10/12-bit
4:2:2 YCrCb or 12-bit 4:4:4 RGB/YCrCb pixel output interface with corresponding timing signals.
The CP section contains circuitry to enable the detection of Macrovision encoded YPrPb signals for
525i, 625i, 525p, and 625p. It is designed to be fully robust when decoding these types of signals.
VBI extraction of CGMS data is performed by the VDP section of the ADV7604 for interlaced,
2
progressive, and high definition scanning rates. The data extracted can be read back over the I C
interface.
