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.:
