A method and system are provided in which broadcast signals are received and converted into data streams for processing. A user is enabled to select preferred broadcast stations for monitoring and signals from the selected stations are converted into digital data streams which are input to first-in first-out (FIFO) memory units to enable a local storage of a segment of predetermined duration of broadcast signals on different FIFO tracks in a user receiving device. The FIFO is dynamically allocated for the selected stations and as each FIFO memory for each selected station becomes full, old information or content is moved out of memory as new information or content is applied to the FIFO. The receiving device includes means for enabling a user to move forward or backward within the stored segment. Partitions or markers are provided to separate broadcast content items, such as sequentially played songs within the stored segment, to enable incremental movement to selected positions within the stored segment. Sections of stored segments which are selected for user processing are copied to separate memory locations for access to avoid interference with the continuing FIFO storage of received broadcast signals.
