This section introduces a reference design for programming the on-board ADV7513 HDMI encoder.
The entire reference is composed of two parts -- the hardware design and the software control
program. A set of pre-built video patterns will be sent out through the HDMI interface and
presented on the LCD monitor as the user launches the provided executable binaries. The design
incorporates certain activities the user could perform to interact with the on-board HDMI TX
encoder.
System Block Diagram
shows the system block diagram of this reference design. The module “Video Pattern
Generator” copes with generating video patterns to be presented on the LCD monitor. The pattern is
composed in the way of 24-bit RGB 4:4:4 (RGB888 per color pixel without sub-sampling) color
encoding, which corresponds to the parallel encoding format defined in Table 5 of the "ADV7513
Hardware User's Guide," as shown below.
