Abstract

An apparatus includes a network receiver for receiving an over-the-air in-band on-channel broadcast signal and extracting broadcast content from the broadcast signal, and an output for delivering the content by way of a first receiver output signal to a plurality of network player devices. A method performed by the apparatus is also included.

Claims

1. An apparatus comprising:

a network receiver for receiving an over-the-air in-band on-channel broadcast signal on a channel selected by a first network player device and extracting encoded broadcast content from the broadcast signal, wherein the network receiver includes;

a front end for converting the broadcast signal to a baseband signal;

a processor for processing the baseband signal according to a portion of a protocol stack to produce an intermediate signal representing encoded broadcast content; and

a network receiver interface for formatting the intermediate signal according to a network access protocol to produce formatted and encoded broadcast content; and

means for delivering the formatted and encoded broadcast content to the first network player device and one or more additional network player devices, wherein the network player devices complete processing of the intermediate signal according to the protocol stack to recover the broadcast content.

2. The apparatus of claim 1, wherein the intermediate signal is encrypted.

3. The apparatus of claim 1, wherein the processor processes the baseband signal according to the protocol stack if the broadcast signal is a digital audio broadcast signal or produces a pulse code modulated signal if the broadcast signal is an analog signal.

4. The apparatus of claim 1, wherein the content includes multiple programs and/or data received in a single broadcast channel and each of the network player devices completes processing of the intermediate signal according to the protocol stack to recover one of the programs and/or data.

5. The apparatus of claim 1,

wherein the network player devices include a network player interface for receiving the formatted and encoded broadcast content, and a processor for processing the formatted and encoded broadcast content receiver output signal according to the protocol stack to recover the content.

6. The apparatus of claim 1, wherein the first network player exchanges command and status information with the network receiver.

7. The apparatus of claim 1, wherein the first network player further includes:

a user interface having controls for activating functions of the network receiver.

8. The apparatus of claim 1, wherein the means for delivering the formatted and encoded broadcast content comprises:

a network router for receiving the formatted and encoded broadcast content and distributing the content to one or more network players.

9. The apparatus of claim 8, further comprising:

a second network receiver for receiving a second over-the-air in-band on-channel broadcast signal and extracting second broadcast content from the second broadcast signal; and

a second output for delivering the second content to the means for delivering the formatted and encoded broadcast content.

10. The network player of claim 1, wherein the protocol stack comprises an in-band on-channel protocol stack.

11. The network player of claim 1, further comprising:

a storage device for storing protocol data units in the intermediate signal.

12. A method comprising:

using a network receiver to receive an over-the-air in-band on-channel broadcast signal on a channel selected by a first network player device and extracting encoded broadcast content from the broadcast signal;

converting the broadcast signal to a baseband signal;

processing the baseband signal according to a portion of a protocol stack to produce an intermediate signal representing encoded broadcast content;

formatting the intermediate signal according to a network access protocol to produce a formatted and encoded broadcast content;

delivering the formatted and encoded broadcast content to the first network player device and one or more additional network player devices; and

using the network player devices to complete processing of the intermediate signal in accordance with the protocol stack to recover the content.

13. The method of claim 12, further comprising:

encrypting the intermediate signal.

14. The method of claim 12, wherein the baseband signal is processed according to the protocol stack if the broadcast signal is a digital audio broadcast signal or converted to a pulse code modulated signal if the broadcast signal is an analog signal.

15. The method of claim 12, wherein the content includes multiple programs and/or data received in the single broadcast channel and each of the network player devices completes processing of the intermediate signal according to the protocol stack to recover one of the programs and/or data.

16. The method of claim 12, further comprising:

exchanging command and status information between the network receiver and the first network player device.

17. The method of claim 12, wherein the first network player device includes:

a user interface having controls for activating functions of the network receiver.

18. The method of claim 12, further comprising:

using a network router to distribute the formatted and encoded broadcast content to the network player devices.
