TV Energy Assessment System

You can download the latest version of the NEEA TV EASY here: 

Download TV Energy Assessment System beta.

Second, unzip the file, and run "install.bat" as Administrator.

This download link will be updated as new updates are released. beta (September 22, 2023)

  1. Tolerates typical non-numeric power meter values like "NaN" beta (September 5, 2023)

  1. Updates to VA_data.csv contents, primarily to eliminate limit levels. beta (July 19, 2023)

  1. Change the file names of report and data spreadsheet outputs to clarify that they are intended for VA collection. In particular, VA reports are now called VA_report_<make>_<model>.pdf and the VA data CSV file is now called VA_data.csv.

  2. Reduce lag during power meter initialization. TV EASY now tries to connect to power meters repeatedly with short timeouts rather than once with a long timeout.

  3. Tweak power meter logging code to reduce the risk of a memory leak in rare cases. beta (July 7, 2023)

  1. Support has been added for Yokogawa WT1800-series power meters.

  2. TV EASY now supports fixed range modes in Yokogawa WT200-, WT300-, and WT1800-series power meters.

  3. This release also fixes issues many have experienced with TV EASY's Yokogawa power meter integrations.

We give special thanks to Intertek Hong Kong for providing extensive access to their Yokogawa power meters for software testing, and further thanks to all the labs that have tried out pre-release versions of TV EASY and provided feedback.

v4.0.1.8 beta (May 29, 2023)

  1. TV EASY now supports generating reports for the soon-to-be-released draft ENERGY STAR Televisions v9.1 policy. ​​Draft ENERGY STAR Televisions v9.1 reports are labeled with "CFR" in reference to 10 CFR Part 430 which contains the TV test method newly required in v9.1.

  2. CSV spreadsheets that include all information required to be reported by ANSI/CTA-2037-D are now generated alongside PDF reports. The new data sheets generated with reports are labeled "estar_data.csv" for ENERGY STAR sheets and "neaa_data.csv" for NEEA Policy Proposal sheets.

  3. For exploratory purposes, TV EASY now allows the Standby Power compliance level to be customized when generating NEEA Policy Proposal reports.

  4. Beta support has been added for Yokogawa WT310 power meters (i.e. WT3xx family) to allow for customer testing before full support is confirmed.

v3.19.0.16 beta (Apr 16, 2023)

  1. Fixes a bug causing the Brightest SDR PPS candidates to be reordered if a user navigates from the end of New Test Setup back to the beginning.

  2. Adds a command to reset screen config: useful in custom sequences.

  3. Fixes a bug which caused video to stop recording after a screen configuration step.

  4. Fixes a bug which caused the wrong framerate to be represented in video output files.

  5. Applies image brightening factor to setup images included in reports: this makes them more readable

  6. Sets the video recording rate to 3 frames per second

  7. Fixes a bug which infrequently caused an error message when closing video output files.

  8. Adds a notice popup when backing up to page 2 of New Test Setup that a new data output folder will be created

v3.19.0.10 beta (April 5, 2023)

  1. Fixed critical bugs in v3.19.0.9 beta, which:

  • assigns a 5-minute test time to SDR tests and a 10-minute time to HDR tests, which is the opposite of what it should be. 

  • skips the screen configuration (dots video) step for reloaded tests. 

v3.19.0.9 beta (March 16, 2023)

  1. TV EASY now keeps a video record of each TV test, replacing large number of the individual images previously saved. Complete video records can take a few gigabytes of storage space, but can be significantly compressed after the fact. In the updated manual, we provide illustrated instructions for using VLC media player to compress TV EASY's video outputs. Archiving these video files is more manageable than archiving large numbers of separate image files (which, for example, can hit cloud storage file count limits).

  2. This release adds support for Basler USB 3.0 cameras.

  3. When generating a report, this release uses existing device metadata in the data folder rather than storing the current device metadata loaded in TV EASY.

v3.18.13.6 beta (February 16, 2023)

  1. This minor release removes an automated mode license restriction which prevented licenses from being activated if less than 1 year remained before their expiration. In this and subsequent releases, automated mode licenses can be activated any time before their expiration date.

v3.18.13.5 beta (January 31, 2023)

  1. When a quickstart feature was recorded as available or enabled, TV EASY would fail to create a test sequence.

  2. When loading a previous test, if any steps were excluded from the test by switching them off, data for later steps would be associated with the wrong test step in a generated report.

v3.18.13.4 beta (January 17, 2023)

  1. Makes Automated Test Mode license status visible without having to open the Licensing popup window.

  2. Adds instructions to the user manual for obtaining and activating Automated Test licenses.

  3. Provides better instructions for configuring a TV before testing, both in TV EASY and in the user manual.

  4. Reorders automated test setup steps so that the camera is focused on the TV when making configuration choices.

  5. Fixes issues with Automated Test Mode license “remaining use” count.

v3.18.12.1 beta (January 9, 2023)

  1. Simplify test sequences. Each test step is now represented by one entry in a sequence.

  2. Give test steps descriptive names throughout TV EASY. For example, "brightest_low_backlight" is now "Brightest SDR - 20% Backlight".

  3. Automatically scroll the Test Status box to show the current step.

  4. Add icons to the Test Status box to quickly communicate steps' statuses.

  5. Simplify navigation controls in the Live View screen. "Skip" and "Rewind" buttons are available when reading an instruction prompt as well as while a step is running. These allow testers to easily navigate to any test step while testing.

  6. Add instructions and exposition to the step selection page.

  7. Make the "power meter make, model, and serial number" metadata field persist between tests. beta (November 7, 2022)

  1. Allows users to set the packet size used to connect to GigE cameras. Different computers have different optimal packet sizes, so this update enables improved performance and avoids potential data loss in worst cases. The default packet size works on all installations. 

  2. Fixes a bug in which the values for dynamic luminance and on mode power were reversed in the explanation of the equations. (This did not affect actual compliance calculations, only explanatory text.) beta (October 13, 2022)

  1. Restored the cross-hairs feature after inadvertently removing it in beta (October 10, 2022)

  1. Gives additional instructions for warming up cameras. Following these expanded instructions will result in more accurate results.

  2. Adds Dark Current Compensation to all Automated Mode tests. This 60-second step corrects for dark current in the camera sensor, improving the accuracy of results.

  3. Moves test instructions popup to the right of the camera view. This makes it easier to view the countdown timer on dynamic video clips.

  4. Adds page numbers to Create New Test pages. beta (October 2, 2022)

  1. Infer camera aperture from framerate to correctly calculate focus distance.

  2. Enable tester to check if camera is warmed up with a live data plot on camera config page.

  3. Add notice before creating a new test or loading an old test telling user to warm up the camera.

  4. Add "reset plot scale" button to Live View.

  5. Add "Generate Report" page separate from testing process.

  6. Add NEEA Policy Proposal reports including option to set the parameters used in determining compliance to that proposal.

  7. Overhaul start/stop/pause/rewind controls in live view mode to work in all cases and make sense.

  8. Add support for PPSs without backlight control.

  9. Add "Demo Mode" which shortens test times for training and software evaluation purposes.

  10. Update licensing code.

  11. Suppress spurious camera connection alarms when first starting software.

  12. Add notice to warm up the camera to the automated test mode page.

  13. Fix missing "Back" button on some pages.

  14. Enable tester to record power meter make/model/serial number.

  15. Reduce camera image save rate from choice of 3 or 6 frames per image to choice of 6 or 12, which means that the new 12 fps cameras will save an image every ½ (i.e. 6/12) or whole (i.e. 12/12) second.

  16. Enable tester to easily record whether TV was factory reset or not via toggle.

  17. Save TV setup images before starting a test. (Note: setup images are still lost if you change camera devices midway through capturing them.)

  18. Allow tester to input numeric values for PPS luminances without measuring them with the camera, for software eval.

  19. Enable tester to record the name of the backlight control and the default backlight level of each important PPS.

  20. Clarify wording of quickstart instructions.

  21. Remove MDD instructions. (2037-D drops rules related to not being able to disable MDD.)

  22. Add busy indicators (spinning wheels) when TV EASY takes more than a moment to do something.

  23. Add explanation of test sequences next to the subsequence selection panel.

  24. Add instructions to log network traffic during testing and save network traffic log file.

  25. Clarify pre-test notice.

  26. Enable tester to record minimum and maximum temperatures and humidities.

  27. Add option to omit all supplemental sections.

  28. Narrow TV EASY window to fit on lower resolution screens.

  29. Under the hood, update the Python code to use Python 3.10, which extends the horizon for support for the Python libraries we use.

  30. Remove unused columns from the report.

  31. Clean up the compliance summary tables.

  32. Add plots of camera temperature.

  33. Ensure UI elements in TV EASY with a scroll bar reset when launching TV EASY.
