SunVideo Test (rtvctest)

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

The rtvctest is available in SunVTS2.0 as a customtest. To enable the test to show up on the SunVTS user interface, you must:

1. edit the .customtest_OtherDevices file in the SunVTS bin directory

2. uncomment the line starting with the label SunVideo.

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

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

rtvctest Subtests

The rtvctest is divided into four sub-tests: PROMCheck, memory, Jalapeno, and CL4000. The PROMCheck sub-test 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 sub-test verifies the interface logic between the SBus, A/D conversion chips, and the CL4000 compression engine. The CL400 sub-test 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. Table 21-1 lists these modules and their associated test sequence numbers.

rtvctest Options

Figure 21-1 rtvctest

You may test the SunVideo card without any video device (camera, video disc player, or VCR) connected to a 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 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 following sources:

Video Source	Definition
None	No video source.
NTSC	A National Television System Committee (NTSC) video source, which is the video standard in the United States and Japan.
PAL	A 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 following ports:

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

rtvctest Command Line Syntax

/opt/SUNWvts/bin/rtvctest [fmt=none|ntsc|pal]
[port=none|cv1|cv2|svhs] dev=rtvc_device

Arguments
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: cv1 Composite video input port 1 (RCA type) cv2 Composite video input port 2 (RCA type) 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 rtvcn, where n is the device number (from 0 to 31) of the SunVideo card under test.
