2 Detailed Description
The TVP6000 is a digital video encoder designed for systems requiring high-quality display of computer
graphics, video, video conferencing, and Internet content. It is designed to convert a digital video input data
stream into NTSC or PAL composite video output. Digital input formats include 8 or 16 bit YUV 4:2:2 or 8
bit CCIR–656 YUV. Analog output formats are NTSC and PAL.
The encoder provides picture quality enhancement features such as overscan compensation, which allows
up to a 12.5% down scaling of pixels (horizontal) and lines (vertical) to allow fitting a VGA frame on a NTSC.
A 3-tap antiflicker filter greatly reduces annoying flicker associated with displaying progressive scan
graphics data or text on an interlace display, like TV. The output has simultaneous S-video and composite
baseband video (CVBS) via three 10-bit DACs. Programmable features such as blank levels, color burst
amplitude, luminance and chrominance gains, subcarrier frequency, luminance delay allow for easy
optimization of picture quality and subcarrier genlock capability when used with a compatible video decoder
provides accurate color reproduction even with nonstandard or unstable video sources such as a VCR.
See Figure 2–1 for an overview of the major functional blocks of the TVP6000.
2.1
Initialization
Upon power up, the TVP6000 is initialized by the internal logic to display a color bar. With this feature, the
TVP6000 is able to demonstrate basic functionality while using only a 27-MHz clock signal at the LLC pin
or the XTAL1 and XTAL2 crystal pins. No software programming is required for this initial operation. This
serves as a quick diagnostic tool during the initial debug of a system.
The DACs can also be optionally turned off immediately after reset by connecting the XDAC pin (pin 64) to
VDD if the initial color bar display is not desired. In this case, video is not output after reset. See Section 2.11,
Register Descriptions for details about the default values immediately after power up.
