DESCRIPTION
The STA450A is designed for digital radio receivers
compatible with the XMRadio SDARS System and in-
tegrates all the functions needed to perform the Ser-
vice Layer and Source Decoding:
– Bitstream Synchronization
– Service Layer (SL) Demultiplexing
– Auxiliary Data Management
– Conditional Access (CA) Control
– Service Components Extraction
– Service Components Decryption
– Audio and Voice Decoding
The extracted Audio and Data are made available
through different interfaces:
