1 Functional 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.

1.1 Description 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.

2 Board Level Description

Board Level Description
The TVP5154EVM consists of the TVP5154EVM module and the encoder EVM module. A 4-row 120-pin connector connects the boards. The block diagram of the EVM set is shown in Figure 1 .

2.1 Test Points and Jumpers

The TVP5154EVM was designed with test points and jumpers to help in evaluation and troubleshooting. Each jumper is set by default in its preferred state for the TVP5154EVM. There are test points for SCL, SDA, 3.3 V, and 1.8 V. All digital video data for each decoder core are brought out to a dual-row header, which allows easy hookup to test equipment. The I2C address selection is made with two shunt jumpers, which are only read after a reset or at power up. The default address is 0xB8. If the address needs to be changed, the TVP5154 must receive a reset.

Note: If the I2C address is changed on either the TVP5154 board or the encoder board while the

2.2 Common Board Interface

The TVP5154EVM uses a 4-row 120-pin connector to share common signals and the 5-V power supply between the boards. This connection allows multiple backends to be connected to the TVP5154EVM. The EVM package is shipped with an encoder module. This connector shares all digital video bits (Y[7:0]), all video clocks (VS, HS, GLCO/FID, and DATACLK), 5 V, ground, I2C bus (SCL and SDA), and reset.

2.3 Video Input Description

The TVP5154EVM decoder has an analog input channel that accepts two video inputs for each decoder core. The decoder supports a maximum input voltage range of 0.75 V, therefore, an attenuation of one-half is needed for most input signals with a peak-to-peak variation of 1.5 V. The parallel termination before the input to the device is 75 Ω . The two analog inputs can be connected as either two selectable composite video inputs, or one S-video input.
The TVP5154EVM allows the user to have up to two composite inputs or one S-video input for each of the four-channels. The EVM software sets up and controls this input selection. The S-video input uses two connectors, one for the luma channel and one for the chroma channel.
The EVM has a resistor network on each of the inputs. These networks attenuate the signal and allow a 75- Ω resistor to ground to be placed after the anti-alias filter for termination.
Each input has an anti-alias filter that can be in-circuit or bypassed by jumpers (JP1–JP8). To select the filter, the shunts need to be positioned to short positions 1-3 and 2-4. To bypass the filter, the shunts need to be moved to short positions 1-2 and 3-4 as shown in Figure 2 . The boards are shipped with the filter bypassed.
TVP5154EVM is powered up, that device will not recognize the new I2C address. The reset button on the TVP5154EVM must be pressed and WinVCC must be reconfigured for the new I2C address.
Figure 2. Anti-Aliasing Filter Selection

2.4 Video Output Description

The 8-bit digital video outputs of the TVP5154 are routed to the four 32-pin headers (H2–H5), the DM642, and finally to the 120-pin edge connector along with all video clocks on the TVP5154 module. The encoder module connects to the 120-pin connector, and is capable of receiving digital video with or without embedded syncs. The analog outputs of the encoder module are composite, S-video, and component. For the user’s convenience, all of these outputs come out of the encoder module simultaneously.

Software Installation

6 Software Installation

The system comes with the anti-alias filters bypassed. To connect the filters, you must rotate the appropriate jumpers (JP1–JP8) as described in section 2.3.
The I2C slave address can be selected with jumpers JP9 and JP10. There are four possible addresses: B8, BA, BC, and BE. The default setting for these jumpers is for the shunt to short pins 2-3, which selects 0xB8. These are connected to pins 117 and 118, which are read at power up. If you move both the jumpers to positions 1-2 and reset the board, the video decoder now responds to I2C slave address 0xBE. If you choose to change the address, you must exit, restart WinVCC, and configure the software to use the new I2C slave address.
WinVCC is a Windows application that uses the PC parallel port to emulate I2C, providing access to each device on the I2C bus. WinVCC makes use of CMD files, a text editable file that allows preset video setups to be programmed easily.
This feature allows the user to easily set multiple I2C registers with the press of a button. WinVCC also has property sheets for the TVP5154, which allows the user to control the I2C registers with a GUI.
All necessary software for the TVP5154EVM is provided on the enclosed CD. Perform the following steps to install WinVCC:
1. Explore the provided TVP5154EVM Software CD.
2. Install Port95NT.exe. This is the parallel port driver used by WinVCC. This driver must be installed and
the PC must be rebooted before WinVCC operates correctly. This does not affect normal parallel port operation.
3. Install Setup.exe. Click Next at all prompts and click Finish to complete the installation process. This
installs WinVCC onto the PC. No reboot is required.
4. Run WinVCC.exe.

8.2 WinVCC Configuration Dialog Box

The WinVCC Configuration dialog box (see Figure 10 ) should now be visible. This dialog box configures the I2C bus on the TVP5154EVM. All settings from this dialog box are stored in the Windows registry and are restored the next time the program is started. After initial installation, VID_DEC is set to TVP5154 and VID_ENC is set to 7311 Encoder.
The I2C slave address for each device must match the I2C slave address selected by jumpers on the TVP5154EVM. These jumpers are set by the factory to use 0xB8 for the TVP5154 and 0x54 for the Encoder. It is also important to select the correct Specific Device type for the video decoder. TVP5154 and 7311 Encoder must be selected for this EVM.
All Program Options must be enabled. Disabling these options is only required if debugging a problem with the I2C bus.
Clicking OK begins I2C communication with the selected devices.

8.4 Real-Time Polling

Real-time polling provides polling functions that execute continuously in the background, when enabled via the Real-Time Polling dialog. There are two polling functions. The function that applies to the TVP5154 is VIDEO-STANDARD AUTO-SWITCH POLLING.
When the TVP5154 detects a change in the input video standard, it automatically switches to operation in the detected standard (which includes all necessary I2C register initialization) for proper decoding of the input video. To enable auto-switch on the TVP5154, the Set Video Standard register must be set to auto-switch mode (Reg 0x28 = 0x00).
If the WinVCC auto-switch polling function is enabled, the detected video standard status from the TVP5154 is polled until a change in the input video standard (or in the TVP5154 sampling mode) is detected. When a change is detected, the video encoder is reprogrammed as needed for the detected standard. Using this feature, the video source can change its video standard and the system displays using the new standard, without user intervention.
When using the TVP5154 EVM with the DM642 and a composite output from the 7311 encoder, it is required to disable auto-switch polling by clicking on the ENABLED button in the Real-Time Polling dialog box as shown in Figure 12 .
The real-time polling dialog can also be accessed once WinVCC is up and running by clicking Real-Time Polling in the Tools menu.
