APTION ACQUISITION
The US Closed Caption data is transmitted on line 21
(525-line timings) and is used for Captioning information,
Text information and Extended Data Services. Full details
can be found in the document “Recommended Practise for
Line 21 Data Service EIA-608”
Closed Caption data is only acquired when TXT21.CC ON
bit is set.
Two bytes of data are stored per field in SFRs the first bye
is stored in CCDAT1 and the second byte is stored in
CCDAT2. The value in the CCDAT registers are reset to
00H at the start of the Closed Caption line defined by
CCLIN.CS<4:0>. At the end of the Closed Caption line an
interrupt is generated if IE.ECC is active.
The processing of the Closed Caption data to convert into
a displayable format is performed by software.
19 DISPLAY
The display section is based on the requirements for a
Level 1.5WSTTeletextandUSClosedCaption.Thereare
some enhancements for use with locally generated
On-Screen Displays.
The display section reads the contents of the Display
memory and interprets the control/character codes.
From this information and other global settings, the display
produces the required RGB signals and Video/Data (Fast
Blanking) signal for a TV signal processing device.
The display is synchronized to the TV signal processing
device by way of horizontal and vertical sync signals
provided by external circuits (Slave Sync mode). From
these signals all display timings are derived.
