1Functional Description

The TVP5154EVM evaluation module is a printed circuit board designed for evaluation of the TVP5154 quad video decoder. The board includes the TMS320DM642 digital signal processor (DSP) and is designed with a 120-pin connector, which allows a connection to multiple backends; the evaluation module (EVM) is shipped with a professional encoder module. The board is designed to provide ease of use, while allowing full evaluation of the video decoder.

1.1Description Overview

The TVP5154EVM uses the PC parallel port to emulate the I2C bus, which provides communication with

the TVP5154 video decoder, DM642, and the video encoder. The Windows™ Video Control Center (WinVCC) application software that communicates with the devices via the I2C is provided on the EVM CD-ROM.

The analog video inputs supported by the TVP5154EVM include composite video and S-video. More detail about the video inputs is discussed in section 2.3 Video Input Description. In general, the video decoder converts the analog video input signal into digital component data. This data and the associated clocks

from the video decoder are sent to the DM642, which provides various image capture and display modes. The DM642 is setup in I2C slave mode and is controlled through virtual I2C registers. The video encoder then converts the digital data from the DM642 back into analog video. The analog video outputs supported by the EVM include composite video, S-video, and component video. These are all output simultaneously.

To experiment with the programmable features of the TVP5154 video decoder and the video encoder, the parallel port of the TVP5154 is connected to the parallel port of a PC. WinVCC, a Windows-compatible application provides the user interface for performing register-level and high-level control of the TVP5154 video decoder and the video encoder.
