VPS
Video Programming System (VPS) data is used for program delivery control
signaling. VPS is a scheme for controlling VCR recording. VPS is used only with the
PAL standard and it is received during line 16 of the VBI comprising a total of 13
bytes per frame.

WSS
In MPEG domain, Wide Screen Signaling (WSS) data is carried as aspect ratio in
the sequence header of the video stream. IRDs construct WSS signaling from this
field, requiring them to reorder. WSS can also be delivered inside the PES data.
WSS is used to indicate the aspect ratio of the picture. The IRD inserts WSS on line
23 in PAL standard only.

VPS Stream Status – Displays the presence of VPS data in the VBI PES.
VPS Output Status – Displays the presence of VPS data in the VBI output
signal.
VPS Insertion – Enables or disables insertion of Video Program System data in
to the VBI output signal.
WSS Stream Status – Displays the presence of WSS information in the
incoming VBI PES. If the insertion type is selected as from Video AR, then the
WSS is generated using the aspect ratio of the incoming video. In this case, the
WSS stream status indicates the presence of this type of WSS.
WSS Output Status – Displays the presence of WSS information in the VBI on
the output.
WSS Insertion – Enables or disables the insertion of the WSS signal in the
video output signal. The following options are available:
DISABLE – Stops the RX8000 inserting WSS on the video output signal.
-
ENABLE – VBI PID – Enables insertion of WSS in to the video output signal
-
where the WSS data is sourced from the VBI PID.
