4.13.1.5 Gemstar Features
4.13.2 Data Output Format (DOF)
The Data Output Format stage will add the following data items to those received from the VBI
Formatting unit:
It will then perform the following operations:
The data output flow issued by the Data Output Format is inserted into an ITU-R BT.656-type
digitized stream which complies with specifications ITU-R BT.656, ITU-R BT.1364 and SMPTE
291M.
In particular, the data flow follows the 8-bit data coding convention. Ancillary data is coded as “Type
2" 8-bit data items (as defined in both ITU.1364 and SMPTE 291M specifications).
A maximum of 100 bytes are used in the Blanking Interval for ancillary data. For more information,

Generation of Per-byte Parity check flags.
Search of Gemstar data during the line 21 (NTSC) or line 22 (PAL), regardless of the field
information.
Optional Extended slicing during all the VBI (line 5 to 25 /NTSC or 2 to 25 /PAL), regardless of
the field information.
Recognition and check of usual Gemstar Frame code (x011x1x1b)
Recognition and check of tighter Gemstar Frame code (10110111b)
