Typical data transfer rates of the output data are:
Audio: mostly in double-digit kbit / s
Video: several hundred kbit / s to several Mbit / s (with triple-play services)
Typical data rates available are:
analog modem: up to 56 kbit / s
ISDN: 64 or 128 kbit / s
DSL and cable modems: 0.4 to 50 Mbit / s
FTTH: 10 Mbit / s to 1 Gbit / s
Ethernet 10 Mbit / s, 100 Mbit / s, 1 Gbit / s or 10 Gbit / s
Since the representation of the data should take place simultaneously with the receipt, a sufficient data transfer rate available. It is necessary that the data transmission rate, which stands for the transmission are available, is greater than that used for streaming data transmission rate. To send the audio and video data must be compressed before transmission. In most cases, this lossy because the only way a manageable amount of data per unit time can be achieved.
To different periods of data packets in the network to compensate and prevent related stoppages, the media player buffer is used. Therefore, playback also delayed slightly, typically by 2 to 6 seconds. During transmission is not, it will increase by some media players dynamically.
Because video data generally have a higher data rate than audio data, also a much greater compression is required. This is about the algorithms and sophisticated with respect to computational power consuming.
With the same type of compression while the quality decreases as the data transfer rate to which the data stream is to be reduced. The visible and audible quality of a stream depends so much upon the following factors:
the type and quality of the starting material
The compression method used
exploited for the transmission data rate, which is usually limited by the Internet.
