DEFINITION

Classification: 348/555

For receiving more than one format at will (e.g., NTSC/PAL):

(under subclass 554) Subject matter including a specific circuitry that enables the receiver to receive and display

two or more signal formats.

(1) Note. A conventional receiver receives and displays only on signal standard. A standard is limited to the number of lines, frame rate, and aspect ratio. Signals which have the same number of lines, frame rate, and aspect ratio wherein the only difference is the stage of signal development, such as R, G, B, or composite or SVHSs luminance and chrominance components are classified in subclass 554.
