摘要： Methods and apparatuses for concurrently recording multiple radio channels. A recorder includes a wideband tuner having a complex mixer for converting a received wideband RF signal to a complex signal that is then digitized. A digital front end module applies a number of complex down-mixers to the digital complex signal to generate the multiple radio channels in the baseband. Each one of the multiple radio channels in the baseband is further filtered, decimated and demodulated. A digital signal processing unit encodes each demodulated channel according to an audio compression format and stores the then encoded audio content to a storage unit. An RBDS decoder parses radio data service information associated with the stored audio content. The radio data service information is stored in a first section of the storage unit while the encoded audio content is stored in a second section of the storage unit.
摘要翻译：同时记录多个无线电频道的方法和装置。记录器包括具有用于将接收到的宽带RF信号转换成然后被数字化的复信号的复合混频器的宽带调谐器。数字前端模块将数个复数下混频器应用于数字复合信号，以在基带中生成多个无线电信道。基带中的多个无线电信道中的每一个被进一步滤波，抽取和解调。数字信号处理单元根据音频压缩格式对每个解调的信道进行编码，并将所编码的音频内容存储到存储单元。 RBDS解码器解析与所存储的音频内容相关联的无线电数据服务信息。无线电数据服务信息被存储在存储单元的第一部分中，而编码的音频内容被存储在存储单元的第二部分中。
