The IC also contains closed caption and extended data services encoding (line 21), and
supports teletext insertion for the appropriate bit stream format at a 27 MHz clock rate
(see Figure 66). It is also possible to load data for the copy generation management
system into line 20 of every field (525/60 line counting).
A number of possibilities are provided for setting different video parameters such as:
• Black and blanking level control
• Color subcarrier frequency
• Variable burst amplitude etc.
