Bit Rate

the amount by which an audio signal can be compressed) 
depending on the type of broadcast. This enables the amount 
of stations on a multiplex to be maximized. Speech and News 
are often broadcast at a lower Bit Rate; music needs a higher Bit 
Rate for good fidelity.

Time and Date

information.
