Abstract:
1. An apparatus for generating a data stream having a series of segments using data organized in subsequent data frames, a data frame having more important and less important data, comprising: a packetiser for packetising data from a data frame into the series of segments having a first segment, a second segment, and a third segment preceding the first segment, where the packetiser is operative to store data according to the following order: an information block adder for adding a first information block to the first segment, where the information block adder is operative to add information on a location, at which the amount of data in the third segment begins, to the first information block, wherein the apparatus for generating a data stream is a hardware apparatus, wherein a frame includes scale factors and weighted spectral values corresponding to original spectral values weighted by the scale factors, and wherein the packetiser is operative to packetise the frame such that all scale factors of the frame are included in the first segment, and data included in the third segment or the second segment include weighted spectral values.
