• CC3 – Secondary synchronous caption service (608 or 708)

The default caption service is OFF. Selecting CC1 or CC3 with an EIA-708 embedded

signal will decode the derived 608 data, if present. The 608 captioning data and 708

data is extracted at the same time.

Closed captioning supports 112 characters as per EIA/CEA-608B 6.4.1:

Upper and Lower Case Characters ABCDEFGHIJKLMNOPQRSTUVWXYZ

abcdefghijklmnopqrstuvwxyz

Accented Characters àáâçèéêíîÑñóôúû

Punctuation Characters ! , . ; : ’ ” # % & @ / ( ) [ ] + - ÷ < > ? ° ¢ $ £ ®

Some characters are not available such as the “e” with the dieresis above it. The

French word Noël uses this character. The ë in Noël would appear differently on the

screen. Also, Ñ is the only capital accented letter as shown above.
