Abstract
An apparatus for switching symbols in parallel broadcast channels to time division multiplexed data streams comprises first and second ping-pong buffers. The first ping-pong buffer is configured to store a first plurality of the parallel broadcast channels therein. The second ping-pong buffer is operable to store a second plurality of the broadcast channels therein. The second plurality of broadcast channels arrive at the second ping-pong buffer prior to the arrival of the first plurality of broadcast channels at the first ping pong buffer. The apparatus also comprises a routing switch connected to the outputs of the first and second ping-pong buffers, and a first frame assembler connected to the routing switch. The routing switch controls the writing of the contents of the second ping-pong buffer to the first frame assembler.
