Problems solved by technology

Another considerable problem is that during the transcoding of the MP3 encoded data packets, which already form a signal representation presenting a reduced signal quality, further reductions in signal quality must also be taken into account
Therefore, data streaming has the problem that it is only suitable for conveying signals with low signal quality
Moreover, the reproduction device exhibits the problem that it is only suitable for reconstructing the signal from the received data stream in question

Embodiment Construction

[0048] Figure 1 shows an output device 1 for a data stream DC, said device taking the form of a general-purpose personal computer (PC). The output device 1 includes a data source 2 , combining means 3 , output means 4 and an output terminal 5 .

[0049] The data source 2 is implemented with a compact disc playback device capable of reproducing a compact disc (CD) on which the signal is recorded by means of compression methods according to the MPEG3 layer 1 standard (abbreviated as MP3) , the signal represents a piece of music. When playing such an optical disc, the data source 2 can generate a time sequence of so-called MP3 encoded data packets and provide said sequence to the combination device 3. Fig. 1 only shows two and data packets (i.e. the first data packet DP1 and the second Two data packets DP2) adjacent time series. It should be pointed out at this point that the data source 2 can alternatively be realized with a hard disk capable of storing MP3 encoded data packet...

Abstract

A data stream (DC) for transmitting a signal, which data stream is produced by means of a compression method and includes time-sequential data packets (DP1, DP2), which data packets (DP1, DP2) each represent a signal portion which appears during a time interval, includes combination data packets (KP) which are each intended for the representation of two time-sequential data packets (DP1, DP2).

Description

technical field [0001] The invention relates to transmitting a data stream of a signal, said data stream being derived from the signal using a compression method and said data stream comprising time-sequential data packets, wherein each data packet represents a portion of the signal occurring within a time interval. [0002] The invention also relates to an output device for a data stream derived from a signal using a compression method, said output device having a data source suitable for generating and supplying data packets, each data packet representing a time interval and each data packet having a substantial amount of data; and data compression means adapted to compress the total amount of data; and output means for outputting a data stream through said output device. [0003] The invention also relates to a data compression method for compressing a substantial amount of data required to transmit a signal, said method comprising the steps of: receiving data packets each ...
