Generating DVD Catalyst benchmark Screen Rating values


Applies To

  • Handheld PC Professional
  • HPC2000
  • Windows CE 2.11
  • Windows CE 3.0
  • Windows CE .net 4.x


The DVD Catalyst Screen Rating benchmark was developed by DVD Catalyst in conjunction with HPC:Factor to provide a data metric by which legacy device users could use the interface in the PocketDVD and DVD Catalyst products to produce optimised video files for their devices.

Before optimised video files can be generated, DVD Catalyst must be given enough information to produce the Screen Rating metric for the device. HPC:Factor records screen ratings for devices in the Devices & Specifications system, however this list is not complete and recent advances in graphical hardware driver models have in many cases improved performance over and above the original values recorded on the system.

This article discusses how to generate an optimised screen rating value for your Handheld PC and how to submit it for inclusion into the Devices & Specifications database.


More Info

The information in this article is written for use against devices which support the GAPI graphical sub-system or a variant of it. Parts of the information will be directly relevant to devices outside of the support sphere of GAPI however instructions for benchmarking on such devices are not covered specifically in the following section.

How-to Guide

Before you begin you must ensure that you have all of the necessary prerequisites to complete the benchmark

  • A Handheld PC
  • WinCESoft's GAPI 3.10 or higher, compatible GX or Direct Draw CE compatible graphics adapter and driver for your Hardware
  • TCPMP version 0.70 or higher (available from the HPC:Factor downloads section)
  • DVD Catalyst 2.4 or higher
  • The DVD Catalyst benchmark file (mirrored here or available from dvdcatalyst.com)

Getting Started

  1. Copy the GAPI driver CAB, TCPMP CAB or GX or driver and the DVD Catalyst benchmark file to your Handheld PC
  2. Install GAPI or the driver / GX file as per the instructions

    Configuration For GAPI

    1. Configure the GAPI driver against the make and model of your Handheld PC. If the device selection does not appear towards the end of setup or during first run open GAPI Setup from the start menu, tap the Set Device button and from the list carefully chose your Handheld PC.
      GAPI Select Device
    2. It is recommended for performance reasons that you attempt to run GAPI with the setting 'Enable framebuffer - cache' enabled. If your device exhibits any instability you should disable this setting.

  3. Install TCPMP

    Configuration For TCPMP

    1. Run TCPMP and ensure that GAPI (or your GX/Direct Draw driver) is configured as the primary driver. To do this, choose the Options menu
    2. Select Video
    3. Tap Video Driver
    4. Ensure that the correct/most efficient driver is ticked
      TCPMI Select Video Driver
    5. Restart TCPMP if needed

  4. Tap File and select Open file...
  5. Browse to and open the DVD Catalyst benchmark file
  6. To begin the benchmark tap File and choose Benchmark

Overview of the Benchmark Process

The benchmark process is designed to push the hardware in your Handheld PC to its limits in order to statistically assess its capabilities.

During the benchmark process your device may exhibit the following expected behaviours

  • Your Handheld PC may appear to freeze
  • The video will fill the screen, masking the TCPMP interface
  • The video on screen will speed up, slow down and jump
  • The audio playback may sound garbled, speed up, slowed down or out of pitch

Generating the DVD Catalyst Screen Rating

Once the benchmark is complete, TCPMP will display the results of the benchmark process on the screen

TCPMP Results Preview

  1. Tap 'Save Results' in the top left of the screen
  2. TCPMP will report that it has saved the results in the root folder of the devices storage system

  3. Copy the file to your desktop PC
  4. Open DVD Catalyst
  5. Select either Video or DVD to begin

    Note: If you do not have a video file or a DVD to hand look for clock.avi in the Windows Folder on your PC
  6. No settings need to be changed on the initial configuration screen, simply click Next
    DVD Catalyst Settings
  7. On the profile screen click on the Advanced button and then click Calculate

  8. Click on the Import benchmark file button and browse to the benchmark file that you created on your Handheld PC

    Note: Due to a bug in DVD Catalyst 2.5 under some conditions you may need to resize the window in order to see the Import button
  9. Click Calculate and close the window
  10. The DVD Catalyst Screen Rating will automatically be displayed in the screen rating box and can be copied by right clicking the text and selecting copy

Submitting your Screen Rating to HPC:Factor

Once you have generated your screen rating why not submit the information in to HPC:Factor so that other may benefit from the information.

Please ensure that you have performed your benchmark using the benchmark file available to download from this page. Benchmarks generated using other video files will produce different results so it is important that only the one file is used.

Once we receive your screen rating we will add it to the devices & specifications database as soon as possible so that other members of the community can benefit from faster and more efficient video conversion and playback for use with their Handheld PC.
