Abstract:
A method of clipping a specified segment with a raised precision from a continuous medium in a digital broadcasting system comprising a transmitter for transmitting a plurality of continuous media as a multiplexed stream and a plurality of layers of data units including a layer of packets, each packet including frames as data units of a lower layer, the method comprising the steps of:optionally inserting an index in each header of selected packets of said packets at said transmitter, said index indicating a time to be decoded or presented;causing a reference timer to generate a reference time (t) at each terminal;obtaining a start time (Ts) and an end time (Te) of said segment at each terminal, said start time Ts and said end time Te being expressed in said reference time,downloading said continuous medium at each terminal during a period including said start time Ts and said end time Te to obtain a first portion of said continuous medium; andclipping a second portion from said first portion at each terminal such that said second portion starts with a data unit that has been received after said start time Ts and has a first header including a first minimum index and ends just before a data unit that has been received after said end time Te and has a second header including a second minimum index.
