Field Mode
Issuing the 17RG command puts the player into Video Memory Mode, Field Mode.
In this mode, both banks always contain Field 1. Each bank can contain field one
from the same frame of video or field one from two different frames of video. Only
one bank outputs a field at any given time. ODM stores Field 1 in Bank 0. 1DM
stores Field 1 of the same frame or another frame in Bank 1. The VM command
selects the bank from which video is to be displayed: 0VM displays the Field 1
stored in Bank 0; 1VM displays Field 1 stored in Bank 1. Use the 0EM command
to enable continuous video to again pass through Bank 0 or use the 1EM
command to allow continuous video to again pass through Bank 1.
Here is a sequence of commands that can be used to capture a field of video into
memory, display it, then release it:
