Abstract	New telematic services require high data rates for additional information, which can no longer be provided on low bitrate broadcast channels like RDS (Radio Data System) over analog FM. A solution are digital broadcast standards, such as DAB (Digital Audio Broadcast), DRM (Digital Radio Mondiale) or IBOC (In-Band-on-Channel, e.g. HDRadio), which offer about 100x higher bitrates and enable modern and sophisticated traffic management applications. To overcome the hassle of building and integrating a new hardware device for each new tuner and each transmission system, a Software Defined Radio (SDR)-based approach helps implementing several standards in a single system and therefore reduce hardware resources and cost by sharing common functions between different decoder. In this paper, a flexible SDR broadcast receiver system architecture is discussed, which can decode audio and data streams of multiple radio stations and multiple broadcast standards simultaneously. Common modules are time-shared between different channels instead of integrating each tuner as separate path for each concurrently decoded station. A single instance of a processing block is sufficient to handle multiple channels with the help of FIFO memory buffers, provided it can be efficiently used in a time shared manner. Performance requirements and limits for an telematic broadcast SDR receiver are discussed in this paper. A real-time capable wideband FM/RDS receiver and a DAB receiver, which has been realized on a Xilinx Virtex-4 FPGA, will serve as example for discussing required resources and time sharing of hardware broadcast receiver.
