The Safe Title Area
Normal consumer TV’s do not display the whole video picture, and each TV is a little
different, so SMPTE defined a standard called the “safe title area”. The SMPTE
document defining the safe title area is: SMPTE RP 27.3.
The safe title area is the area of the middle of the TV screen that is guaranteed to be
displayed on all TV sets. In order to stay within the safe title area, you must be careful
when calculating your xOffset and yOffset parameters so that your subtitles stay within
the safe title area. The following table defines the safe title area for the HDE-3000
parameters.

The viewUYC Utility
The viewUYC utility is a graphics viewer program for viewing uyc files. It is a single
executable file, and it is a Windows application that will run under Windows
98/NT/2000/XP.
To execute viewUYC just double click viewUYC.exe from within Windows Explorer.
You can associate uyc files with viewUYC.exe in Windows Explorer, and then you can
just double click on uyc files and viewUYC will automatically be executed.
6.7 Graphics Files
HDE-3000 displays bit mapped graphics files in a format known as “YCrCb”. YCrCb is
the component video format inherent in serial digital video. ULTECH created a YCrCb file
format known as “YC” format. Section 6.8 provides details about this file format. Software
developers may choose to produce graphics files directly in YC format. Other HDE-3000
users may create files in several industry formats, then convert them to YC format. A future
version of HDE-3000 software will convert all of the popular formats to YC format as the files
are transferred to the HDE-3000. The current version of software requires a separate
conversion step on a PC using graphics file converters supplied by LINK. LINK provides a
Microsoft Windows program that lets you view YC files on a PC without requiring HDE-3000
hardware.
