Abstract :
A switch architecture is proposed for distributing broadcast and switched videos. The switch consists of set of concentration buses (or input buses), a time division multiplexing (TDM)-based bus matrix, and a set of distribution buses (or output buses). Dedicated time slots in a frame are reserved for the broadcast videos. The remaining time slots are allocated to the switched videos on a first-come-first-serve basis. Videos are switched via time slot assignments which determine the connections within the bus matrix. Two slot assignment algorithms are designed, one for point-to-point transmissions and the other for point-to-multipoint transmissions. The advantages of this switch include: accommodation of multirate videos; support of video broadcasting and multicasting; and modular growth at distributed locations
