R&S®SMCVB-KS18
1 Welcome to the R&S SMCVB-KS18 option
The R&S SMCVB-KS18 is a stream library that provides stream files for testing standard-definition television (SDTV) of the systems DVB, ATSC and ISDB-T. The files are
additional to the SDTV stream files provided in the Basic Streams library R&S SMCVBKS17.
This user manual contains a reference description of the functionality that the stream
library provides. All functions not discussed in this manual are described in the
R&S SMCV100B user manual. The latest version is available at:
www.rohde-schwarz.com/manual/SMCV100B
1.1 Key features
The R&S SMCVB-KS18 stream library consists of the following signals to provide a
comprehensive functional testing on the receivers:
●
●
Welcome to the R&S SMCVB-KS18 option
Key features
Moving and video test pattern signals
Audio and video synchronization signals
Transport streams with moving scenes
Moving picture scenes can be used for a basic functional test of decoders, multiplexers
and terminals. For example, use moving picture scenes for testing set-top boxes
(STBs) in final production. Due to the movement of the picture scenes, any interruption
or transmission error in the data stream or any processing error in the decoder is
immediately recognizable. Due to digital processing, the last frame that was received is
always output in the decoder, even if there are transmission errors. The limitations
imply that images are less useful in functional testing.
Monitor test pattern scenes/still test patterns
Besides checking the transmission of transport streams, it is also necessary to test the
analog processing that occurs in the terminal equipment. Testing the D/A conversion in
decoders and alignment of the picture in television sets generally involves the use of
still images. The analog signal path for audio must also be tested and aligned.
Synchronization between video and audio
These sequences make it possible to detect a delay between picture and sound in
transmission and decoding.

2.1.8 SMPTEBARS (29 Hz)
SMPTEBARS consists of color bar and "reversal blue bar" information and an IWQB
plus pluge signal for TV test signal.
Example of use: The "reversal blue bar" is arranged such below the regular color bars
that the blue channel is at full amplitude in both signals at the same time. For correct
adjustment of the color reproduction on a monitor, the red and green channels are disabled. Also. the monitor is set such that the two bars cyan/magenta and magenta/cyan
appear with the same brightness. The lower part of the signal contains a white pulse
and a black signal with ±4 IRE steps (pluge). The composed signal is useful for adjusting the monitor brightness and contrast. Also, it is useful for the color reference signals
-1 and +Q for adjusting the correct phase relationship with the aid of a vector scope.

2.1.13 HSWEEP (25 Hz)
The whole video frequency range is swept over a line. The sweep starts with 5.5 MHz
at the beginning of the line down to 0 Hz in the middle of the line. It increases again to
5.5 MHz at the end of the line. The signal is generated with an amplitude of 100%. It
has a constant frequency response over the whole frequency range at a high energy
density. Also, it is superimposed to a grey level of 50% HSWEEP1 is generated with a
phase of 180 degrees.
Example of use: Amplitude-frequency response and frequency-dependent phase distortions are visible through the evaluation in the time domain. If distortions are present
purely from the amplitude-frequency response, the sweep envelope is distorted symmetrically about the middle of the line. Exclusively for group-delay distortion, an asymmetrical ripple of the sweep envelope regarding the middle of the line is obtained.
