7 1 Introduction 1 Introduction 1.1 HDMI Frame Generator Overview The HDMI (High-Definition Multimedia Interface) Frame Generator software (short: Frame Generator or software ) is a stand-alone software utility. It provides semi-automatic control of different Keysight Technologies (formerly Agilent Technologies) HDMI TMDS (Transition-Minimized Differential Signaling) Signal Generator configurations for physical layer tests. It is a flexible tool for trouble-shooting and debugging. The Frame Generator complements the full Test Automation Software (Keysight N5990A opt. 010, 150, 151 and 250, depending on the configuration), which provides automated physical layer compliance tests and device characterization. It allows a wide range of HDMI video formats to be generated and provides control over parameters such as color depth and color code. It comprises jitter insertion for jitter tolerance tests, to set the skew and other key parameters. The software runs on a standard Windows XP or Windows 7 PC and controls the hardware test resources through appropriate interfaces such as LAN (Local Area Network). The HDMI Frame Generator software is able to drive the following Keysight HDMI TMDS Signal Generator configurations: the E4887A platform which is based on a ParBERT 81250A and external jitter sources and test accessories such as cable emulators (for short: ParBERT configuration). See Figure 1. The compact Arbitrary Waveform Generator (AWG) configuration which is based on M8190A. See Figure 2. Figure 1: Keysight ParBERT and accessories Figure 2: Keysight M8190A and accessories 7

21 5 Using the Software 4. Specify and select Power Supply in the section Power Supply. It is available and recommended, if Bias-Tees are used. 5. Clicking on the Show Connection... button, shows the basic connection set-up for the selected configuration. 6. After setting the desired configuration click on the Connect button. When the Connect button is pressed, the desired connections will be checked and, if available, established. After successfully establishing the instrument connections and returning to the main window, the labelling and functionality of the Connect button will change to Set. Pressing the Set button will apply the selected video format etc. to the connected instruments. 7. Unless you are an advanced AWG user and have created and loaded your HDMI settings individually, leave the Connection Dialog window by selecting the Apply HMDI Setting and Close button. The necessary HDMI settings the AWG system will be applied automatically. Note that it is necessary to start the AWG setup specific firmware(s) on the Host PC first. 8. Use the Cancel button to terminate the Connection Dialog window without connecting. CAUTION If no Bias-Tees are used, the M8195 hardware will take care of offsets required by the HDMI Standard. This requires, that all channels always have correct terminations applied. Removing its termination or applying a wrong termination will result in a safety disabling of the M8195A outputs. It is very important that all channels are properly terminated and an over-voltage condition is always avoided. If not correctly performed, this could result in damage to the M8195A hardware and any products connected to it. Modifying the connections from the recommended set-up is done at your own risk and might cause over-voltage conditions, wrong terminations and interfere accurate run of the HDMI Frame Generator software. Always follow instructions as given. 5.2 Main Window After the connection to the instruments has been established the main window appears again as shown in Figure 14. It offers basic functionality as well as access to top-level test parameters and status information. The properties of the video frame are divided into three sections: 1. Video Format 2. Packets 3. Video Content 21

22 5 Using the Software Figure 14: HDMI Frame Generator Main Window (Instruments connected) After the desired parameters have been selected, the following steps can be carried out: The Connect/Set button. The Connect button starts a dialog box that establishes the connection to the userselectable instruments such as the signal generator. For details, refer to the section Connecting to the Instruments. The Connect button will turn into the Set button after the Frame Generator is connected to the instruments. Use the Set button to download the pattern and set the clock frequency for the selected video mode. After the Frame Generator has been connected to the instruments the Align... button will be available to the left of the Set button. The Align... button is only available for AWG-based setups. Use it to align the two M8190A blades or to show the alignment values again. Use the Create button to save a HDMI video frame pattern in a user-selectable location and in a ParBERT-ready format, i.e. on the disk of the PC that runs the HDMI Frame Generator software. The pattern file can then be loaded into the ParBERT manually at any time. The Create button is only available for ParBERT based setups. Use the Setting button to save current settings of the Frame Generator to a file. This file can then be loaded back into the Frame Generator to assign the saved settings in the current state of the Frame Generator software. The settings file is able to contain multiple settings. For details, refer to the section Setting Dialog. 22

23 5 Using the Software Selecting Close will terminate the HDMI Frame Generator software. The status line indicates the action which has been performed last, for example loading a pattern into the instrument or, in the case of a ParBERT based setup, saving a pattern to a file Video Format The Video Format section in the upper part of the main window allows the user to select several parameters: Video Mode The desired Video Mode can be selected from a broad choice of CEA-861 video modes by means of a drop-down selection box. Color Depth A Color Depth of 24, 30, 36 or 48 bits can be chosen. Color Mode The Color Mode is user-selectable, too, and includes RGB as well as multiple YCbCr modes. The quantification can be Full Range or, Limited Range. Content The Content flag can be selected (Not specified, Graphics, Photo, Cinema and Game), in either 2D or 3D formats (Frame Packing, Side-by-Side (half), Top-Bottom). Check box selections are available for: DVI Compatibility Mode Check this option to enable the DVI interface which transfers only video. Audio Audio Output will be accessible if supported by the hardware. Null Packets Selecting Null Packets will fill up the blanking periods to achieve balanced pattern. Scrambled HDMI 2.0 introduces scrambling to reduce the EMI and to improve the DC balancing. To send scrambled video select the Scrambled check box. Before performing the test with scrambling an extra step is required. It is necessary to enable the scrambling in the sink using the HDMI SCDC Controller. TMDS Clock 1:40 If the TMDS Clock 1:40 property is selected, the TMDS data bit rate is changed to 40 times the TMDS clock rate instead of 10. Just as for scrambling, it is necessary to use the HDMI SCDC Controller to inform the sink of the relationship between the TMDS clock rate and the TMDS data bit rate. This function is only available for HDMI 2.0. TMDS Information Some information about the current frame format is shown in a table. The table comprises TMDS Signal Generator specific information, such as the memory usage. 23

24 5 Using the Software Restrictions when using a ParBERT configuration: The most important information is whether the selected sequence can be generated with the ParBERT sub-system of the TMDS Signal Generator or not. If the sequence can be generated, this is indicated by Valid for ParBERT True at the bottom of the Parameter List in the main window. All available video modes can be generated with 24 and 48 bit color depth. In addition, 36 bit color depth can be generated for most video modes. Some 30 bit color depth formats cannot be generated. For details, see the E4887A data sheet. Another important parameter is the ParBERT Frequency Multiplier. The following relationship holds: ParBERT Bit Clock = TMDS Clock x Frequency Multiplier Restrictions when using an AWG configuration: None Packets On the right side of the main menu, several Info Packets can be selected. They will be sent with each frame during the blanking period. Packet Position Offset The position of the desired packets in the blanking can be selected. The offset of the packet position is relative to the Hsync Active Start. A value of 0 will place the packets directly after the Hsync Active Start. Any value above 0 will shift the first and all residual packets by the amount of symbols as given in this field. For example, a value of 2 will shift the appearance of the first packet by 2 symbols from the Hsync Active Start. The possible empty parts between the Hsync Active Start and the first packet position will be filled with control characters. Packet Viewer/Editor The desired packets content can be shown and edited. Press the Edit... button to edit the packets with the Packet Viewer/Editor as shown in Figure 15. Figure 15: HDMI Frame Generator Packet Viewer/Editor In this window every bit of each packet can be modified. To edit a packet, select it in the combo box in the top left-hand 24

25 5 Using the Software corner of the dialog. Then click the Binary Value or Hex Value of a packet in one of the lists. The check box Send Packet determines whether the packet is actually transmitted in the video stream or not. Packet configurations can also be saved to and loaded from a file using the buttons Export... and Import... After closing the dialog with Close, it is necessary to click the Set button in the main window to make the changes take effect. NOTE When a parameter is changed in the main window which affects the packet contents (e.g. video mode, color mode, 3D mode, etc.), all packets are reset to their defaults values in order to reflect the parameter change Video Content In the middle of the right-hand side of the Frame Generator main window, the video content can be set. This section provides control of the parameters that define the horizontal color gradient. It offers the following basic choices: Default A gray bar will be created according to the rules in the Compliance Test Specification (CTS). See Figure 16. Color Bar A color bar with 8 bars is created, starting from white at the left and ending with black at the right and with an intensity of 75%. See Figure 17. Figure 16: Preview for Default Video Content Figure 17: Preview for Color Bar Video Content Parametric A parametric color scale will be created. If this content is selected a dialog will be opened that allows the user to set the parameters for the color scale. It is the same dialog as will be opened if the Edit->Color Gradient Setup menu is selected. For more details see Color Gradient Setup. Range Marker A special pattern to determine the correct display of full and limited range colors. The three black bars should appear as a single bar when the display is limited range, or as a black bar between two dark gray bars when the display is full range. The same applies to the three white bars. See Figure 18. Chess board A simple chess board pattern with 8 6 fields as shown in Figure

26 5 Using the Software Figure 18: Preview for Range Marker Video Content Figure 19: Preview for Chess Board Video Content Y420 Test Image A special pattern combining Y420 B&W Bar and Y420 Color Bar according to the HDMI 2.0 CTS. This test image is used to verify that a DUT shows YCbCr 4:2:0 content correctly. It is only available for HDMI 2.0. See Figure 20. Figure 20: Preview for Y420 B&W Bar Video Content Y420 B&W Bar A special black and white pattern defined in the HDMI 2.0 CTS. This test image is used to verify that a DUT shows YCbCr 4:2:0 content correctly. See Figure 21.

27 5 Using the Software 21:9 Test Img Figure 23: Preview for 21:9 Test Image A special widescreen pattern to determine the correctness of the aspect ratio. The aspect ratio is correct, if displayed black portion is a square and not stretched or deformed. See Figure 23. Images Images are loaded from disk directories to the image list by selecting Add... If multiple images were added to the image list, you can toggle between them. Note that the image will not be stretched! Hence if the image is smaller than the screen resolution the image line and the image row will be repeated until the screen is covered. If the image is bigger than the screen resolution the image is truncated. Delete images from the image list with Remove. 5.3 File Menu The File menu offers the following choices: Selecting Connect will start a dialog box which establishes the connection to the user-selectable instruments. For details, refer to the section 5.1Connecting to the Instruments. Once a connection has been established, it can be disconnected at any time by selecting Disconnect. Set Settings will download the pattern and set the clock frequency for the selected video. Save Segments At will save a HDMI video frame pattern in a user-selectable location and in a ParBERT-ready format. Exit terminates the HDMI Frame Generator software. 5.4 Edit Menu The Edit menu includes the following options: 1. Frame Timing Setup 2. Color Gradient Setup 3. Instrument Parameters Setup Frame Timing Setup The Frame Timing Setup window allows advanced users access to all relevant timing parameters. The parameters are listed in a table and can be set individually, as shown in Figure

28 5 Using the Software Figure 24: Frame Timing Setup Dialog Use this window, for example to stress your device by applying deviations from the standard format or to generate your own video pattern by starting with a reasonably close standard pattern. Some of the parameters influence the data rate. If a data rate deviation is to be generated, this can be achieved by changing the Frame Rate. The data rate can be computed by: DataRate = (Hblank + Hresolution) (Vblank + Vresolution) Bits per pixel Frame Rate Select Ok if you want to apply the selected parameters or simply close this window to close this window without changes Color Gradient Setup This sub-menu provides additional options that are not available from the Video Content group of the main window. It is shown in Figure 25 and offers the following choices: 28

29 5 Using the Software Figure 25: Color Gradient Setup Dialog Compliance Mode Only for ParBERT In Compliance Mode a gray scale wedge is generated. It is the same video content as the Default option in the main Window. The color value is incremented by one per pixel from 0 to 255. For Video Formats with more than 256 pixels of horizontal resolution, multiple wedges will be generated. For the entire sub menu, the Preview button displays the pattern on the PC monitor as shown in Figure 26. Figure 26: Preview for Compliance Mode Video Content Parametric Gradient The Parametric mode allows you to define independent start and stop values for the three colors. In addition, a Bit Mask can be set for each color. It is used to blank specific locations in the pattern and has to be entered in hexadecimal format. The parameters shown in Figure 25 will generate the frame in Figure 27. Figure 27: Preview for Parametric Video Content Adjustable Color Bar 29

30 5 Using the Software Color Bar generates the SMPTE (Society of Motion Picture and Television Engineers) pattern shown in Figure 28. Figure 28: Preview for Adjustable Color Bar Video Content Load from File This will read frame data from a file. PRBS-Function The pseudo-random binary sequence (PRBS) function generates a pseudo-random color scheme as shown in Figure 29. Figure 29: Preview for PRBS Video Content After selecting the video content: Pressing Apply will calculate the selected pattern, load it into the instrument and leave the Color Gradient Setup window open for further changes or tests. Depending the PC processing power and on the selected parameter combinations, the pattern calculation and loading can take up to a few minutes. OK will adopt and save the selected parameters without applying them and close the window. The changes will only become effective when the Set button in the main menu is selected. Multiple parameter changes can thus be combined and calculation and loading time minimized by advanced users. Cancel will close the Color Gradient Setup window and discard any changes Instrument Parameter Setup The Instrument Parameter Setup allows the relevant instrument parameters to be controlled. The selection window comprises four groups for a ParBERT configuration (see Figure 30): 1. Clock 2. Clock Jitter 3. Data Jitter 4. Output Additionally AWG-based setups include two more groups (see Figure 31): 5. Signal Controls 6. Filter Clock 30

31 5 Using the Software The Clock group allows to modify the HDMI clock setup, either by means of the Data Rate, the corresponding Pixel Clock, Frame Rate or Deviation. Changing any of these parameters will auto-calculate the others. Figure 30: Instrument Parameter Setup Dialog for ParBERT configuration Figure 31: Instrument Parameter Setup for AWG configuration 31

32 5 Using the Software Clock and Data Jitter The Clock Jitter setup group shows the values of the sinusoidal (periodic) jitter Amplitude, Frequency and Phase parameters which are generated either by the clock jitter source of the TMDS generator (ParBERT) or calculated into the waveform (AWG). Check the Enable box and set the required jitter values to use this specific jitter. The same applies to the Data Jitter. Note that the clock and data jitter parameters can be selected independently (default). Alternatively, the clock jitter parameter settings can be applied to the data jitter (Same as Clock). For both, clock and data jitter, an independent 2nd Jitter Component can be selected and specified. Output The Output setup group provides access to the TMDS signal generator output channels (clock and data) in terms of amplitudes and delay. Signal Controls The Signal Control group allows the sequence to be started and stopped. Filter The Filter allows you to set Filter parameters such as transition times and cable emulators, which are calculated into the waveform and downloaded to the AWG. If you are using a ParBERT based setup the selected parameters can be applied individually for instant validation by selecting the adjacent Apply buttons. Apply All Settings will set all parameters at the same time. For an AWG-based setup only the Apply All Settings is available since specific parameters are calculated into the waveform and cannot be set in real-time. Close terminates the window without changes. 5.5 Setting Dialog Once all parameters are set as wanted, the Setting Dialog can be used to manage settings, either as single setting or as setting lists as shown in Figure

33 5 Using the Software Figure 32: Settings Dialog The Setting Name contains the name of the actual setting and can be modified by the user. This name will be replaced by a default name if one of the controls on the main window changes the mode. The user can add a comment in the Comment text box. A setting contains all setting values that are visible in the main window and the frame timing setup dialog. It does not contain the images itself but the file names of the images. The setting can then be: added to the setting list (press the Add button) or saved on the hard disk as a setting file (press the Save button), or a setting can be loaded from the hard disk (press the Load button). The setting list contain all the settings that have been added via the Add button above. This setting list can be managed as follows: A setting can be activate by means of the Activate Entry button or just by double clicking on an entry. The activation will set all parameters in the main window to the values of the setting and activates the setting on the instrument. A setting can be removed from the settings list by means of the Remove Entry button. The Load List and Save List buttons are for loading and saving a settings list. End the dialog with Close. 5.6 Tools Menu Color Coding This menu provides a tool for converting color code data and is shown in Figure

34 5 Using the Software Figure 33: Color Code Conversion Tool It allows the RGB Unlimited color mode with different color depths to be converted to several output color modes such as RGB restricted and YCbCr ITU-R SCDC Controller Figure 34: SCDC Controller Software For HDMI 2.0., before sending out scrambled video or it a different clock ratio is to be used, it is necessary to set the TMDS configuration register in the sink. That is possible by using the SCDC Controller Software which is available in the Tools Menu of the Frame Generator. Clicking on Tools->SCDC Controller a window like that shown in Figure 34 will 34
