Abstract

A memory control system for a network that broadcasts to multiple terminals content data including music, video and the like, and also including commercial advertisements. A memory in the terminal unit stores content data that is played upon a loss of signal from the broadcast network. The memory also stores commercial advertisements for playback from the terminal memory according to schedule control instructions, which are also stored in a memory at the terminal unit. Writing of content to a memory and reading content from the memory may be executed concurrently by interleaving. A microprocessor arbitrates use of input, output and memory buffers such that reading content from memory provides content output maintaining uninterrupted real time play even when new content data is being stored concurrently. Content data memory addresses are stored in sector tables that are further arranged in File Allocation Tables in a second memory.
