A method and apparatus is provided for the delivery of digital television and interactive broadband service in a manner that maximizes the useage of the digital broadcast spectrum. A digital television signal is transmitted to a given broadcast area in a relatively small part (for example, a 1 MHz band) of one or more licensed portions of the digital broadcast spectrum. Interactive broadband service is delivered within at least a portion of the same broadcast area covered by the broadcast digital television signal, in the remainder (for example, a 5 MHz band) of an unused part of the same licensed portion of the digital broadcast spectrum as is occupied by the digital television signal, or within an unlicensed (unused) portion of the digital broadcast spectrum. The broadcasting of the digital television and delivery the interactive broadband service occur simultaneously. In one embodiment, digital television and broadband service are delivered by the same equipment within the same bandwidth.

An apparatus for processing a hybrid broadcast service, the apparatus comprising a reception module for receiving broadcast signals though a broadcast channel or contents through a broadband channel for the hybrid broadcast service, wherein the broadcast signals include data for the hybrid broadcast service and an EAM (Emergency Alert message) and a processor for receiving a request from a companion device and sending at least one of a content or continuous components or files or data or media or the data are a part of the hybrid broadcast service which is currently selected.

A receiver-server device that is a multi-tuner radio equipped with antenna capacity suitable for acquiring signal from multiple stations and providing remote access to that signal on a live or near-live basis via circular memory buffers accessible via the Internet is provided. Further, a smart user device is connected with the receiver-server device through the Internet as an input/output controller to select, scan and hear the available stations in live, near-live and fully time-shifted modes as well as in place-shift mode. A user may rewind or fast-forward the audio stream in a variety of increments or to pause the audio stream or return the audio stream to live monitoring. A home radio is provided for a user that can be accessed from anywhere, irrespective of the user's location, and performs in live, near-live and time-shifted modes.

Methods, systems and devices for locating a wireless identity transmitter with a central server connected with one or more proximity broadcast receivers, such as stationary receivers or mobile devices operating as wireless receivers. The wireless identity transmitter may be a compact device configured to broadcast messages, such as through Bluetooth advertisements, including an identification code. When within proximity, a proximity broadcast receiver may receive broadcast messages from the wireless identity transmitter and relay location information along with the wireless identity transmitter's identification code to a central server as sighting messages. The proximity broadcast receiver's own location may provide an approximate location for the wireless identity transmitter. The central server may process sighting messages, which may include signal strength information, to accurately locate the wireless identity transmitter. The central server may transmit data to third-party devices and/or mobile devices of users in response to receiving sightings messages.

A system includes a first signal processing subsystem in communication with a first radio receiver and configured to selectively generate audio data of individual radio channels within a first frequency range; a second signal processing subsystem in communication with a second radio receiver and configured to selectively generate audio data of individual radio channels within a second frequency range; and a controller configured to: receive a streaming request from a remote requestor, and configure one of the signal processing subsystems to fulfill the streaming request based on a target radio channel of the streaming request and the associated frequency ranges. In response, the configured signal processing subsystem is configured to fulfill the streaming request by generating audio data of the target radio channel. The generated audio data is then transmitted to a remote recipient.

The present disclosure provides a wireless audio data transmission method and related devices. The method comprises: broadcasting, by a transmitting device, a hybrid auxiliary synchronization packet to a plurality of receiving devices. The hybrid auxiliary synchronization packet comprises a first link information and a second link information, the first link information is used by a first receiving device among the plurality of receiving devices to synchronize with the transmitting device and establish a first Broadcast Isochronous Group (BIG) link, and the second link information is used by a second receiving device among the plurality of receiving devices to synchronize with the transmitting device and establish a second BIG link; transmitting a first broadcast data packet based on the first BIG link, and/or transmitting a second broadcast data packet based on the second BIG link. The method enables more flexible applications of multi-channel wireless broadcast audio.
