Abstract: 收到的数据以块为单位加到一个纠错单元和一个数据保持单元。如果纠错单元正常执行纠错,则纠错单元的输出就储存在帧缓冲区中。如果纠错单元未正常执行纠错,则在数据保持单元中的数据就储存在帧缓冲区中。按这种方式执行第一次纠错处理。位数据被从帧缓冲区储存的每个块中依次以位为单元读出,执行第二次纠错处理,并返回到帧缓冲区。对从帧缓冲区以块为单位输出的数据进一步执行第三次纠错。

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
