Up and Down Conversion
Standard-deinition video resolution employs a 4:3 aspect ratio, and high-deinition video resolution
employs a 16:9 aspect ratio. Up-conversion is the process of iting standard-deinition video (with a
4:3 aspect ratio) into a high-deinition, 16:9 frame. Down-conversion is the opposite process.
PIX recorders have various options for up and down conversion:
