Abstract
A method is provided for receiving and processing a digital radio broadcasting signal. The method includes the steps of receiving a digital radio broadcasting signal including content, storing encoded content, and decoding the stored encoded content to recover decoded content. The stored encoded content can include protocol data units or packets. The stored encoded content can be recovered by decoding the encoded content according to a logical protocol stack.
Claims53
A method for receiving and processing a digital radio broadcasting signal, the method comprising the steps of:
- receiving a digital radio broadcasting signal including content;
- storing encoded content;
- using a processor to decode the stored encoded content to recover decoded content;
- specifying a dropout tolerance parameter;
- and
- stopping the storing step when the number of dropouts exceeds the dropout tolerance parameter.
A method for receiving and processing a digital radio broadcasting signal, the method comprising the steps of:
- receiving a digital radio broadcasting signal including content;
- storing encoded content;
- using a processor to decode the stored encoded content to recover decoded content;
- and
- blending the decoded content to mute when the stored encoded content is defective due to the quality of the digital radio broadcasting signal falling below the threshold quality criteria.
A receiver for receiving and processing a digital radio broadcasting signal, the receiver comprising:
- an input for receiving a digital radio broadcasting signal including content;
- a memory for storing encoded content;
- and
- a processor for decoding the stored encoded content to recover decoded content, wherein the prOcessor blends the decoded content to mute when the stored encoded content is defective due to the quality of the digital radio broadcasting signal falling below a threshold quality criteria.
A method comprising:
- receiving an in-band on-channel digital radio broadcasting signal including encoded content;
- extracting a baseband signal from the in-band on-channel digital radio broadcasting signal;
- using a processor to process the baseband signal according to a logical protocol stack to produce encoded encapsulated packets including encoded audio content and program specific data;
- storing the encoded encapsulated packets;
- separating the encoded audio content and the program specific data;
- decoding the encoded audio content to recover decoded content;
- and
- using the decoded content to produce an output.
A receiver comprising:
- an input for receiving an in-band on-channel digital radio broadcasting signal including encoded content;
- a circuit for extracting a baseband signal from the in-band on-channel digital radio broadcasting signal;
- a processor for processing the baseband signal according to a logical protocol stack to produce encoded encapsulated packets including encoded audio content and program specific data;
- a memory for storing the encoded encapsulated packets, wherein the processor retrieves the encoded encapsulated packets from the memory and separates the encoded audio content and the program specific data and decodes the encoded audio content to recover decoded content;
- and
- an output circuit producing an output from the decoded content.
A system comprising:
- a receiver including an input for receiving an in-band on-channel digital radio broadcasting signal including encoded content, a circuit for extracting a baseband signal from the in-band on-channel digital radio broadcasting signal, a processor for processing the baseband signal according to a logical protocol stack to produce encoded encapsulated packets including encoded audio content and program specific data, and a first memory for storing the encoded encapsulated packets;
- and
- a player including a second memory for storing encoded encapsulated packets and a processor for decoding the stored encoded content to recover decoded content.
