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.

Claims (26)

1. A receiver 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, said receiver comprising:

front-end circuitry for receiving and processing data in one of a Level A or a Level B SMPTE 425M compliant format;

a storage device for receiving Level A formatted data and for reading out Level B formatted data or for receiving Level B formatted data and for reading out Level A formatted data; and

back-end circuitry for further processing and outputting Level A formatted data when Level B formatted data is received or Level B formatted data when Level A formatted data is received.

2. The receiver of claim 1 wherein said storage device is a FIFO register having a capacity of at least two lines of video data.

3. The receiver of claim 1 wherein said storage device is operated as a line multiplexer to convert data in a Level B format to data in a Level A format.

4. The receiver of claim 1 wherein said storage device is operated as a line demultiplexer to convert data in a Level A format to data in a Level B format.

5. A transmitter 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, said transmitter comprising:

front-end circuitry for receiving and processing data in one of a Level A or a Level B SMPTE 425M compliant format;

a storage device for receiving Level A formatted data and for reading out Level B formatted data or for receiving Level B formatted data and for reading out Level A formatted data; and

back-end circuitry for preparing Level A formatted data for transmission when Level B formatted data is received or for preparing Level B formatted data for transmission when Level A formatted data is received.

6. The transmitter of claim 5 wherein said storage device is a FIFO register having a capacity of at least two lines of video data.

7. The transmitter of claim 5 wherein said storage device is operated as a line multiplexer to convert data in a Level B format to data in a Level A format.

8. The transmitter of claim 5 wherein said storage device is operated as a line demultiplexer to convert data in a Level A format to data in a Level B format.

9. A method performed in a single device 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, said method comprising:

receiving and processing data in one of a Level A or a Level B SMPTE 425M compliant format;

inputting 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 said storage device; and

further processing of Level A formatted data when Level B formatted data is received or Level B formatted data when Level A formatted data is received.

10. The method of claim 9 wherein said method is preformed in a video transmitter.

11. The method of claim 10 wherein said inputting and reading out is performed in a FIFO register having a capacity of at least two lines of video data.

12. The method of claim 10 wherein said storage device is operated as a line multiplexer to convert data in a Level B format to data in a Level A format.

13. The method of claim 10 wherein said storage device is operated as a line demultiplexer to convert data in a Level A format to data in a Level B format.

14. The method of claim 9 wherein said method is preformed in a video receiver.

15. The method of claim 14 wherein said inputting and reading out is performed in a FIFO register having a capacity of at least two lines of video data.

16. The method of claim 14 wherein said storage device is operated as a line multiplexer to convert data in a Level B format to data in a Level A format.

17. The method of claim 14 wherein said storage device is operated as a line demultiplexer to convert data in a Level A format to data in a Level B format.
