Predictive frame; contains motion-compensated difference information from

the preceding frame

PID

RS232

Recommended Standard 232 is a serial binary single-ended data and

control standard for serial ports.

Standard Definition refers digital video resolution not exceeding 480 lines in

an interlaced format. The aspect ratio may be 4:3 or 16:9.
