摘要： A method improves audio acquisition time by nascent signal caching. The receiver system includes the processor which contains the ASRC (Arbitrary Sample Rate Converter), demodulator, channel splitter, channel decoder and middleware & application along with the secondary storage system. The nascent digital broadcast radio signal after the sample rate conversion is cached in a secondary storage and given as input to the demodulator. The demodulator starts the demodulation process over the received signal by utilizing default channel parameters and detects the channel parameters of the received signal. If the default channel parameters are different from the detected channel parameters, the demodulator starts the re-demodulation process with the detected channel parameters over the nascent digital signal cached in the secondary storage, instead of waiting for a subsequently transmitted signal, thereby improving the audio acquisition time.

摘要： Embodiments presented herein are directed to “content linking multicast streaming” The embodiments connect a listener to over-the-air (OTA) broadcast radio content using an Internet Protocol (IP) multicast stream of the broadcast radio content when, for example, (i) a traditional broadcast radio receiver is not available, or (ii) an OTA broadcast radio signal that carries the content is not available. For example, when recovery of the OTA broadcast radio signal by a car radio is not possible because of poor reception or because the car radio is not configured with a suitable broadcast radio tuner, the embodiments generate a link to a multicast stream of the OTA broadcast radio content (also referred to as a “multicast broadcast radio stream” or simply a “multicast stream”), and provide the link to the car radio. The car radio can then access the multicast stream of the OTA broadcast radio content using the link.

摘要： A broadcast response system provides, e.g., a radio broadcast listener with the ability to obtain media content such as music or speech while listening to the radio. The user can respond to items in the radio broadcast such as advertisements, fund raising drives, or interactive listener polls during the broadcast. Data such as song title and artist, author or publisher and the IP address for the location where the digital version of the content is stored, can be transmitted using, e.g., the RBDS/RDS data stream. A reference number representing song title and artist, author or publisher and the IP address for the location where the digital version of the content is stored can also be employed for ease of implementation. This reference number can reside in a lookup table to be accessed by broadcast response server.

摘要： A method includes receiving a distributed radio signal at a wireless communications device (WCD) from a first service provider. The method includes generating a bookmark associated with a first content item included in the distributed radio signal. The bookmark is generated based on radio application data when the WCD is radio-enabled, and the bookmark is generated based on pseudo-radio application data when the WCD is not radio-enabled. The method also includes transmitting the bookmark and a content request associated with the first content item from the WCD to a content source.

摘要： A wireless communication system wirelessly receives a Frequency Modulation (FM) signal including audio data and Radio Data System (RDS) data. The wireless communication system audibly plays the audio data and graphically displays the RDS data from the FM signal. The wireless communication system detects action codes in the RDS data, and in response, initiates a wireless communication session with a wireless communication network. The wireless communication system also audibly captures user data. The wireless communication system then wirelessly transfers the captured user data for delivery to a server over the wireless communication session.
