METHOD AND APPARATUS FOR CONTENT NAVIGATION IN DIGITAL BROADCAST RADIO
First Claim
1. A multichannel receiver, comprising:
- a receiver for receiving content from a multichannel signal that is broadcast containing commercial content and non-commercial content on multiple broadcast streams contained within a single channel and wherein one or more of the broadcast streams among the multiple broadcast streams contains supplemental content;
at least one circular buffer for storing at least portions of a Layer 1 service data stream containing the commercial content, non-commercial content, and the supplemental content; and
a processor coupled to the receiver, wherein the processor is operable to;
selectively navigate among the commercial content, the non-commercial content and the supplemental content without changing a channel; and
time shift triggers for commercial content play based on the selective navigation.

Abstract
A low cost DAB multichannel receiver comprising a simplified buffering method for buffering content segments from multiple streams contained within the DAB channel, where the receiver enables the listener to navigate buffered content segments from multiple streams within the DAB channel while enabling the broadcaster to control the timeshift of commercial content to the receiver output stream. The receiver'"'"'s buffered content grows over time and is cleared when tuning away from the channel, thus encouraging listeners desiring to tune in to new content to instead navigate to new buffered segments. Broadcaster control of the listener experience may be enabled by setting content control fields which are observed in the broadcast by the multichannel receivers. Additional embodiments are disclosed.

23. A multichannel broadcast system, comprising:
-
a transmitter; at least one encoder coupled to the transmitter, wherein commercial audio, non-commercial audio, supplemental content and control information are multiplexed on each in-band on-channel (IBOC) channel of a multichannel digital audio broadcast (DAB); and wherein the multichannel broadcast once demodulated and decoded enables selective navigation among the commercial content, the non-commercial content and the supplemental content without changing an IBOC channel and uses the control information to control the time shift playing of commercial content based on the selective navigation. - View Dependent Claims (24, 25, 26)

27. A non-transitory computer readable storage medium at a multichannel receiver unit comprising computer instructions to:
-
selectively navigate among commercial content, non-commercial content and supplemental content without changing a channel after receiving and decoding content from a multichannel signal that is broadcast containing the commercial content and the non-commercial content on multiple broadcast streams contained within a single channel and wherein one of the broadcast streams among the multiple broadcast streams contains the supplemental content; and time shift triggers for commercial content play based on the selective navigation. - View Dependent Claims (28)

29. A method of content navigation in a digital audio broadcast radio, comprising:
-
receiving content from a multichannel signal that is broadcast containing commercial content and non-commercial content on multiple broadcast streams contained within a single channel and wherein one or more of the broadcast streams among the multiple broadcast streams contains supplemental content; buffering in a circular buffer at least portions of a Layer 1 service data stream containing the commercial content, non-commercial content, and the supplemental content; selectively navigating among the commercial content, the non-commercial content and the supplemental content without changing a channel; and time shifting triggers for commercial content play based on the selective navigation.

30. A method of content navigation in a digital audio broadcast radio, comprising:
-
receiving content from a multichannel signal, wherein the multichannel signal is broadcast containing commercial content and non-commercial content on multiple broadcast streams for a single channel and wherein one or more of the broadcast streams among the multiple broadcast streams contains supplemental content; and navigating among the commercial content, the non-commercial content and the supplemental content without changing a channel; and time shifting the play of commercial content based on the navigation among the commercial content, the non-commercial content and the supplemental content.

31. A method of broadcasting a digital audio broadcast, comprising:
-
encoding and multiplexing on each in-band on-channel (IBOC) channel of a multichannel digital audio broadcast (DAB) commercial audio, non-commercial audio, supplemental content and control information; and wherein the multichannel broadcast once demodulated and decoded enables selective navigation among the commercial content, the non-commercial content and the supplemental content without changing an IBOC channel and uses the control information to control the time shift playing of commercial content based on the selective navigation and a pre-set number of content selection algorithms used for navigation selected by the control information.
