Data disk generator for use in modulator in digital broadcasting system, has input-first-in-first out-storage for receiving inputs of forward error correction-frames, which are dispensed by multiple pipes of physical layer

摘要

The data disk generator (106,116) has an input-first-in-first out-storage for receiving inputs of forward error correction-frames, which are dispensed by multiple pipes of a physical layer. An input-first-in-first out-controller is provided for monitoring the input-first-in-first out and for directing an output of one of the input-first-in-first outs based on the monitoring result. A data disk-first-in-first out-controller is provided for monitoring the data disk-first-in-first out and for directing the data-disk first-in-first out for output of the forward error correction-frame. Independent claims are included for the following: (1) a modulator with a time-and frequency-interleaving module; and (2) a method for operating a data disk generator.
