Functional Description  
The MOS circuit SDA 5642 is used to retrieve the required data for the Video Program System  
(VPS) service from the data line No. 16 which is included in the CVBS signal. These data are  
decoded according to the specification given in "Richtlinie ARD/ZDF Nr. 8 R 2".  
This circuit incorporates the digital functions of the VPS decoder SDA 5640 and the analog  
functions of the video processor SDA 5232 on one chip. Together with a reduced number of  
external components this chip is a low cost solution for the VPS detector. The single chip  
solution can retrieve the data from line 16 of the CVBS signal. These data are decoded,  
checked for transmission errors and are stored in registers for further processing by a  
microcontroller. The I2C-Bus interface is used for communication of a microcontroller with the  
VPS-decoder.  
The recording of programs by a VTR is controlled by the VPS label, a program related dataco-  
de which accompanies each TV program during its transmission.  
As a result the circuit prevents errors in the recording, as can be seen when using the timer  
control, when programs are delayed, or are longer than expected.
