TIME-ALIGNMENT MEASUREMENT FOR HYBRID HD RADIO tm TECHNOLOGY
A method for processing a digital audio broadcast signal in a radio receiver, includes: receiving a hybrid broadcast signal; demodulating the hybrid broadcast signal to produce an analog audio stream and a digital audio stream; and using a normalized cross-correlation of envelopes of the analog audio stream and the digital audio stream to measure a time offset between the analog audio stream and the digital audio stream. The time offset can be used to align the analog audio stream and the digital audio stream for subsequent blending of an output of the radio receiver from the analog audio stream to the digital audio stream or from the digital audio stream to the analog audio stream.
Activating a digital radio broadcast receiver in a vehicle
A system and method of controlling a digital radio broadcast receiver in a vehicle includes: detecting an instruction to activate the digital radio broadcast receiver; accessing a software application at the vehicle in response to the instruction; and activating the digital radio broadcast receiver in the vehicle at the direction of the software application.

Systems, methods, and devices for associating a contact identifier with a broadcast source
A media device including a broadcast receiver that receives broadcast media from a plurality of broadcast sources where the broadcast receiver is tunable to a first broadcast source. The media device also includes a data store that stores a list of contact identifiers where each contact identifier is associated with a broadcast source. The media device includes a user interface that: i) provides a prompt to a user to enable the user to initiate contact with the first broadcast source, and ii) receives a user indication to initiate contact with the first broadcast source. The media device further includes a transceiver that initiates the contact with the first broadcast source by sending a communications session request via a communications network to the first broadcast source that includes a contact identifier associated with the first broadcast source.

Vehicle communication system for receiving frequency modulation and digital audio broadcast radio frequency bands
An antenna system for a vehicle that includes at least one radio frequency (RF) antenna that receives both a digital audio broadcasting (DAB) RF broadcast and a frequency modulation (FM) RF broadcast. A single amplifier coupled to one or more antennas is used to process both the DAB and FM broadcasts.
Receiving device, receiving method, providing device, providing method, programs, and broadcasting system
This technique relates to a receiving device, a receiving method, a providing device, a providing method, a program and a broadcasting system that can notify the receiving side of control information such as the timing to synchronize an application program with progress of a show without using a television broadcast signal. When the application control type written in the application control descriptor is 3, the receiving device acquires application control data from a server, and, for example, acquires and starts a new information service application in accordance with the segment data forming the application control data. When an external device is designated as the command destination device, the receiving device generates a command for the external device, and outputs the command to the external device. In accordance with the command from the receiving device, the external device, for example, acquires and starts the new information service application. This disclosure can be applied in a case where the receiving device is controlled from the broadcasting side.

Digital receiver and digital transmitter having a variable interleaver functionality
A digital receiver includes a pre-de-interleaver processing block for receiving a receive signal including reception data units quantized using a quantization rule. The digital receiver additionally includes a controllable compressor for compressing the data units into a compressed representation, a controllable time-de-interleaver being configured for applying a varying interleaving size in data units, and a controller for controlling the controllable processor or the controllable time-de-interleaver. The controller is configured for controlling the compressor or the time-de-interleaver so that a higher interleaving size such as a higher interleaving time or a higher number of data units per second is applied, when a compression in a lower number of bits is active.
