a typical menu screen used in television receivers. It should
be noted that in this document, commands are written as ei-
ther a one- or two-byte HEX value, separated by a comma,
within curly braces (that is, a sample two-byte OSD com-
mand: {A1,00}).
In the sample programs below, a comment field can be writ-
ten following the command to describe the action of the
command or sequence of commands, where appropriate.
The comment field is identified by an asterisk (*), and any
text following the * is taken as a “comment”. Therefore, to
include a comment in the program, simply add the * at the
beginning of the function description.
