| 20090070597 | Method and Apparatus for Store and Replay Functions in a Digital Radio Broadcasting Receiver - A method includes: receiving a plurality of audio frames, assembling groups of the audio frames into logical recording units, storing a plurality of the logical recording units, retrieving the stored logical recording units, and decoding the retrieved logical recording units. An apparatus that performs the method is also provided. | 03-12-2009 |
| 20100027719 | Systems and methods for fine alignment of analog and digital signal pathways - Methods and systems for temporally aligning audio samples of a digital portion of a radio broadcast signal with audio samples of an analog portion of the radio broadcast signal are disclosed. The methods and systems comprise the steps of receiving a radio broadcast signal having an analog portion and a digital portion; separating the analog portion of the radio broadcast signal from the digital portion of the radio broadcast signal; producing a first plurality of audio samples representative of the analog portion of the radio broadcast signal; retrieving from a memory a stored first time interval corresponding to an approximate time for data representing a first sample of the digital portion to travel through a digital signal path in a receiver, wherein the digital signal path includes a digital demodulator; measuring a second time for data representing the first sample of the digital portion to travel from an input of the digital signal path to an input of the digital demodulator; generating a delay amount for delaying a second plurality of audio samples relative to the first plurality of audio samples such that the second plurality of audio samples is temporally aligned with the first plurality of audio samples by adding the first time to the second time; producing the second plurality of audio samples representative of the digital portion of the radio broadcast signal; delaying the second plurality of audio samples by the delay amount such that the second plurality of audio samples is temporally aligned to within a predetermined amount with the first plurality of audio samples; and digitally combining the first plurality of audio samples with the second plurality of audio samples to produce a combined audio output. | 02-04-2010 |
| 20100166122 | Systems and methods for fast seek and scan functions in a digital radio broadcast receiver - Methods and systems for advancing to another service from a plurality of services in a digital radio broadcast receiver are described. The methods and systems include the steps of receiving an instruction to advance to another service from a man-machine interface of the digital radio broadcast receiver, selecting an entry from a set of entries stored in a memory of the digital radio broadcast receiver responsive to the instruction, wherein each entry identifies a service, and wherein at least some of said services correspond to services identified as receivable, tuning to a first service identified by the selected entry, rendering content received on the first service at the digital radio broadcast receiver, and updating the set of entries stored in the memory of the digital radio broadcast receiver based on at least one criteria. | 07-01-2010 |
| 20110274214 | METHOD AND APPARATUS FOR STORE AND REPLAY FUNCTIONS IN A DIGITAL RADIO BROADCASTING RECEIVER - A method for receiving and processing a digital radio broadcasting signal includes: receiving a digital radio broadcasting signal comprised of two or more multicast contents, playing a first one of the multicast contents, and concurrently storing a second one of the multicast contents. A receiver that implements the method is also provided. | 11-10-2011 |
