ABSTRACT:
A method for converting data received in either a Level A or Level B SMPTE 425M compliant format into either a Level B or a Level A compliant format, respectively, includes receiving and processing data in one of a Level A or a Level B SMPTE 425M compliant format. Inputting the received Level A formatted data into a storage device and reading out Level B formatted data at an output of the storage device, or inputting Level B formatted data into the storage device and reading out Level A formatted data at an output of the storage device. Back-end circuitry further processes the Level A formatted data when Level B formatted data is received or further processes the Level B formatted data when Level A formatted data is received. The storage device is operated as a line multiplexer to convert data in a Level B format to data in a Level A format and is operated as a line demultiplexer to convert data in a Level A format to data in a Level B format. Receivers and transmitters capable of performing the method are also disclosed.
