NETWORK NAME PADDED TO 4 CHARACTERS

Panasonic VCRs require that the network name XDS packet contain either the string “<sp>PBS” or
“PBS<sp>” where <sp> is the space character.  As of Firmware revision R020726 the 8084 will
automatically add a <sp> character to the end of 3 character Network Name packets in order to satisfy
this requirement.

8085 CAPTION TRANSLATOR ‘0 BASED’ INDEX (8085 Only)

Starting with firmware version R020618, the 8085 caption translator has been modified to comply with
the CEB-10-A clarification to EIA-708B rules for the 

Define Windows

 and 

Set Pen Location

 commands.

Previously the top left co-ordinates of the raster were defined as “1,1’. CEB-10-A has clarified that the
top left of the raster should be defined as ‘0,0’.
