SLEU063 1 Functional Description The TVP5160EVM refers to both the TVP5160 board and the ADV7311 board when they are connected together. Both boards share a common interface via a 120-pin connector. This interface provides all data, clocks, I2C communication, and 5-V power to each board. The ADV7311 is a professional grade, 12-bit, 216-MHz, video encoder. This device minimizes potential artifacts caused by the re-encode process.

SLEU063 2.5 VBI Decoder Interface This interface provides a method of connecting an external VBI decoder module to the TVP5160EVM via the H3 and H4 headers. The VBI decoder may be a closed-caption decoder, teletext decoder, or any other VBI decoder currently available on the market that provides the same signals. The pinout of the VBI decoder interface is provided below. Table 3.
SLEU063 2.7 SDRAM On the TVP5160EVM, there are three SDRAM footprints: 50-pin, 54-pin, and 86-pin. These are provided to accommodate the user’s choice of SDRAM that will be used in their final product. By default, the TVP5160EVM is provided with 64-Mbit SDRAM (54TSOPII). If the SDRAM is changed, then the SDRAM configuration register (0x59) will also need to be updated with the correct memory size. This must be programmed before 3DYC or 3DNR is enabled. 2.
SLEU063 3 System Level Description The system block diagram illustrated in Figure 2 provides an example of how the TVP5160EVM may be used for evaluation. Typically, the analog input is a CVBS signal provided by a video source such as a pattern generator or a DVD player running a test DVD. The TVP5160EVM itself is configured with the provided 5-V supply and the parallel port cable. The analog output is typically YPbPr to reduce the number of artifacts caused by backend processing or re-encoding.
SLEU063 4 Required Hardware and Equipment The following lists the required hardware and equipment necessary to use the TVP5160EVM: - TVP5160EVM (provided) - Universal 5-V power supply (provided) - Parallel cable (provided) - Windows-based PC - 1 composite RCA video cable - 1 YPbPr component RCA video cable - Video source (pattern generator, DVD player, etc) - TV or display monitor that supports YPbPr component video inputs TVP5160EVM User’s Guide 9
SLEU063 5 Hardware Setup The following describes how to set up the hardware for the TVP5160EVM. 1. Connect the TVP5160EVM boards together using the 120-pin board connector on each board. 2. Connect a CVBS input to the TVP5160 board and a component cable to the YPbPr outputs of the ADV7311 board. NOTE: For evaluation it is recommended that the YPbPr component video outputs be used in order to bypass the internal video decoder of the TV or video display. 3.
SLEU063 6 Software Installation WinVCC4 is a Windows application that uses the PC parallel port to emulate I2C, providing access to each device on the I2C bus. WinVCC4 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. WinVCC4 also has “Property Sheets” for the TVP5160 which allows the user to control the I2C registers with a GUI.
SLEU063 7 WinVCC4 Quick Start The following describes the steps to take within WinVCC4 in order to get video out of the TVP5160EVM. 1. Once WinVCC4 is executed, the WinVCC4 Configuration screen appears. This dialog box is used to configure the I2C bus. Next to VID_DEC, select the TVP5160 and ensure the I2C address is set to 0xB8. This should match the I2C ADDR jumper on the TVP5160 board. NOTE: If WinVCC4 is running and the TVP5160 board I2C address is changed, power must be cycled on the EVM. Figure 3.
SLEU063 5. At the Real-Time Polling window, ensure that VIDEO-STANDARD AUTO_SWITCH POLLING is enabled and click OK. Figure 4. WinVCC4 – Real Time Polling Screen 6. Load the provided TVP5160EVM.CMD file into WinVCC4 by clicking on Tools -> System Initialization -> Browse. The CMD should be available by default as seen below. Figure 5. WinVCC4 – Main Screen 7. Click the “TVP5160 (SD) + ADV7311” dataset in the window and then click the Program Dataset button to initialize the TVP5160EVM. Figure 6.
SLEU063 8. With a video source provided at the composite video input, video should be viewable on the TV/display monitor. All ADV7311 outputs are enabled simultaneously. NOTE: To ensure the TVP5160 is working properly, go to Video Status by clicking on Edit -> Property Sheets -> TVP5160PNP -> Video Decoder Status and check the H/V/C lock status and the video standard. This is only a check on the TVP5160 board and not the ADV7311 board or the TV/display monitor.
SLEU063 8 WinVCC4 in Depth The following describes how to use WinVCC4 in depth. It discusses various features and screens which the user m ay encounter while evaluating the TVP5160EVM. 8.1 Starting WinVCC4 The Port95NT parallel port driver must be installed before using WinVCC4. WinVCC4 may be started by clicking on Start->All Programs->TVP5160EVM Software->WinVCC4. If the dialog shown in the figure below is displayed, it means one of two things: 1.
SLEU063 8.2 WinVCC4 Configuration Dialog Box The WinVCC4 Configuration dialog box, as seen in Figure 8, should now be visible. This dialog configures the I2C bus on the TVP5160EVM. 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_DECTM will be set to TVP5160 and VID_ENC will be set to ADV7311. The I2C slave address for each device must match the I2C slave address selected by jumpers on the TVP5160EVM.
SLEU063 8.3 I2C System Test The I2C system test of selected registers runs immediately after closing the WinVCC4 Configuration dialog box with OK (unless the I2C system test program options button was disabled). If the I2C system test passes, then only a PASS message will appear. If the test failed, then a dialog box like Figure 9 will appear. See Section 9, Troubleshooting, for details on how to resolve this issue.
SLEU063 If the WinVCC4 autoswitch polling function is enabled, then the detected video standard status from the TVP5160 decoder is polled until a change in the input video standard (or in the TVP5160 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 will display using the new standard without user intervention.
SLEU063 8.5 Main Menu After closing the Real–Time Polling dialog, the main menu is displayed as shown in Figure 11. The menus, which are used to operate WinVCC4, are File, Edit, Tools, Window, and Help. The File menu’s only function is Exit, which terminates the program. The following table summarizes the main menu contents. Figure 11. WinVCC4 – Main Screen Table 4.
SLEU063 8.5.1 System Initialization Clicking System Initialization in the Tools menu displays the dialog shown below. This provides the means for initializing the video decoder and/or video encoder for a particular video mode. The details of the initialization are contained in the command file (with a CMD file extension). The command file is loaded using the Browse… button. Once the command file is opened, a text list displays descriptions of the individual data sets contained within the command file.
SLEU063 8.5.1.1 Adding a Custom Data Set After you program the EVM via the System Initialization tool using the factory-supplied command file, and by using the Property Sheets tool, you can customize the device register settings to suit your needs. To save your custom settings: 1. Reopen the System Initialization dialog via the Tools menu. 2. Click the Append Current Device Settings to Command File button. A dialog requesting a description of the new data set appears. 3.

SLEU063 8.5.2 Register Editing The next section describes the four available modes of register editing: Register Map Editor, Encoder Module Editor, Generic I2C Register Editor, and Property Sheets. Each of these functions can be selected from the Edit menu. 8.5.2.1 Register Map Editor The register map editor, as shown in Figure 13, allows the display and editing of the entire used register space of the device within a simple scrolling text box.
SLEU063 Table 5. Control Register Map Editor Controls Definition Register Window Scrolling text box that displays the address and data for the I2C registers that are defined for the device. Address Edit Box This contains the I2C subaddress that will be accessed using the Write and Read buttons. Clicking on a row selects an address, which then appears in the address edit box. NOTE: After clicking on a row, the Data Edit box contains the data that was in the register window.
SLEU063 8.5.2.2 Encoder Module Editor The encoder module editor, as shown in Figure 14, allows the display and editing of the video encoder registers. This editor works like the Register Map Editor. To open this, click on Edit Register Map in the Edit menu and click on Encoder Module. Figure 14.
SLEU063 8.5.2.3 Generic I2C Register Editor The Generic I2C Editor, as shown in Figure 15, allows the display and editing of any device on the I2C bus. This editor works like the Register Map Editor, except that the I2C slave address must be entered and the Read All button is disabled. To open this, click on Edit Register Map in the Edit menu and then click on Generic I2C.
SLEU063 8.5.2.4 Indirect Register Editor The indirect register editor, as shown in Figure 16, allows the display and editing of the indirect registers (or hardware registers) of the device. To open this, first open the register map editor in the Edit menu for the TVP5160. Then, click the Edit Indirect Registers button. The operation of the controls of the indirect register editor is explained in Table 6. Figure 16. Indirect Register Editor Table 6.
SLEU063 8.5.3 Property Sheets The Property Sheets represent the register data in a user-friendly format. The data is organized by function, with each function having its own page and being selectable via tabs at the top. To open this, click on Edit Property Sheets in the Edit menu and select the device type to edit. When the property sheet function is started or whenever you tab to a different page, all readable registers in the device are read from hardware to initialize the dialog pages.
SLEU063 8.5.3.2 Auto–Update from Device Items 4 and 5 above are referred to as the Auto–Update feature. Auto–Update can be disabled by setting its program option button to DISABLED. This button is located on the initial dialog box (WinVCC4 Configuration). With Auto–Update enabled (default), the user can open both the Property Sheets and the Register Map Editor at the same time.
