A system and method is disclosed for a personal radio recorder. The
personal radio recorder allows for random access of communication signals
by identifying a channel and time. The personal radio recorder is capable
of concurrent reception, storage and playback of a complete spectrum of
individual communication signals. A wide-band signal is received, and
concurrently demodulated into a plurality of individual communication
signals. These audio signals are identified by channel and time.
Individual signals may be simultaneously played, paused, or stored for
later playback. Compression may be used to make efficient use of storage.
Storage may be fixed, removable, or a combination of both. The system is
also capable of storing signals that are digitally formatted, and is
compatible with existing analog or digital playback devices. The personal
radio recorder may playback multiple channels of communications data,
either previously recorded or currently broadcast, to multiple output
stages at the same time.
