SunVTS 3.0 Test Reference Manual

Chapter 28 SunVideo Test (`rtvctest`)

rtvctest verifies the functionality of the SunVideo(TM) SBus card. SunVideo technology captures and compresses video input in realtime, making it possible to have realtime video conferencing over standard Ethernet networks.

rtvctest is available as a customtest. To display the test on the SunVTS user interface, you must:

Edit the .customtest_OtherDevices file in the SunVTS bin directory.
Uncomment the line starting with the label SunVideo.

The rtvctest was originally written for Sundiag(TM) and the messages from the test are displayed on the SunVTS console within a SunVTS INFO message wrapper.

The rtvctest is available under the OtherDevices group, and is only available in the Functional Test mode.

`rtvctest` Subtests

rtvctest is divided into four subtests: PROMCheck, Memory, Jalapeno, and CL4000. The PROMCheck subtest verifies the SunVideo card's programmable read-only memory. The memory test verifies all of the memory on the card, including the 2 Mbytes of memory on the CL4000 compression engine and the memory on the Jalapeno application-specific integrated circuit (ASIC). The Jalapeno subtest verifies the interface logic between the SBus, A/D conversion chips, and the CL4000 compression engine. The CL400 subtest verifies that the compression engine ASIC is able to compress digitized video data from the A/D chips and send this data to the SBus through the Jalapeno ASIC.

The rtvctest is composed of 49 verification test modules. The table below lists these modules and their associated test sequence numbers.

`rtvctest` Options

Figure 28-1 `rtvctest Option Window`

You may test the SunVideo card without any video device (camera, video disc player, or VCR) connected to an input port. However, if you connect a video device to the card, then you must state the format of the video source and the input port to which the device is connected.

Note -

If you do not state both the video source and the input port, the rtvctest prints an error and terminates testing.

Source Format

Select the format of the video source used for testing. You may select from the sources shown in Table 28-2.:

Table 28-2 rtvctest Source Format Options


Video Source	Definition
None	No video source.
NTSC	National Television System Committee (NTSC) video source, which is the video standard in the United States and Japan.
PAL	Phase alternate line video source, which is the video standard in Europe.

Ports

If you have selected a video source for testing, then you must state which input port you have used to connect the source to the SunVideo card. You may select from the ports shown in Table 28-3:

Table 28-3 rtvctest Port Options


Input Port	Definition
None	No input port used.
CV1	Composite video input Port 1 (RCA type input).
CV2	Composite video input Port 2 (RCA type input).
SVHS	Super VHS input port.

`rtvctest` Command Line Syntax

Table 28-4 rtvctest Command Line Syntax


Arguments	Description
`fmt`	Select the format of the video source used for testing. Select either `ntsc` (video standard in the United States and Japan) or `pal` (video standard in Europe).
`port`	If you have selected a video source for testing, then you must state which input port you have used to connect the source to the SunVideo card. You may select from the following ports: o `cv1` Composite video input port 1 (RCA type) o `cv2` Composite video input port 2 (RCA type) o `svhs` Super VHS port
`dev`	You are required to state the SunVideo device when running the `rtvctest` from the command line. Replace `rtvc_device` with `rtvc``n`, where `n` is the device number (from 0 to 31) of the SunVideo card being tested.

Note -

64-bit tests are located in the sparcv9 subdirectory: /opt/SUNWvts/bin/sparcv9/testname. If a test is not present in this directory, then it may only be available as a 32-bit test. For more information refer to "32-Bit and 64-Bit Tests".
