Abstract

A method for interfacing a digital set-top box with a digital television in accordance with Electronics Industries Association standard 775A. According to one embodiment, a multiple program transport stream is received and filtered. The filtering process produces a single program transport stream based on a program selected by a user. The single program transport stream is provided to the digital television over a 1394 bus in accordance with EIA standard 775A. The program association information associated with the single program transport stream is also provided to the digital television. In one embodiment, the invention contains a component performing on-screen display function for user interface information displayed on a DTV.

Claims

1. A method comprising:

receiving a multiple program transport stream;

filtering the multiple program transport steam to a single program transport stream based on a program selected by a user; and

2. The method of claim 1, further comprising:

determining the network topology of consumer electronic devices such that the program transport stream is directed to one or more specified consumer electronic devices.

3. The method of claim 1, further comprising:

directing a module that is not IEEE standard 775A compliant to access an application program interface such that the module transmits bitmap information to an IEEE standard 775A compliant remote device for display.

4. The method of claim 3, wherein the module is a Home Audio-Visual interoperability module that may exist locally or remotely.

5. The method of claim 1, further comprising:

tailoring program association information in accordance with Electronics Industries Association standard 775A; and

providing the tailored program association information to the remote device.
