XDS Display Modes (Z86129 only)
Two preprogrammed XDS display modes are provided.
One provides information about the current program that
would be of interest for “channel grazing”. The second
display shows the grazing packets plus additional XDS
packets which will inform the viewer about the program
content. Information will be displayed as it is received. The
displays use drop shadow mode with 15 scan lines per
row.
The XDSG mode is the GRAZE (channel grazing) display
(Figure 7). The display will contain three rows of
information at the top of the screen, formatted for easy
reading. They will contain the following XDS packet
information:
The XDSF mode is the FULL (information) display (Figure
8). This display shows the same information as the
GRAZE display and adds the program type as well the first
four program description rows (if transmitted). Although
XDS defines eight program description rows, the first four
are identified as containing the most important information.
The display of Program Description is limited to the first
four rows because eight rows would obscure much of the
screen and because more than four rows is not likely to be
sent due to the time required for transmission.
Since 15 scan lines per row mode is being used, rows 10-
13 will appear at the bottom of the screen.
When an XDS display mode has been selected, the
information will be displayed as the appropriate packets
are received. The display will remain on screen as long as
valid XDS data continues to be received. If the 16 Second
Erase Timer is enabled (the default condition), the XDS
display will be erased when no valid XDS data has been
received for 16 Seconds. If subsequent XDS data is
received with displayable packets, that information will
reappear on the screen. XDS data recovery can be active
in the XDS display mode.
The XDS display mode is turned off by selecting a different
display mode.
