functions from MPEG-1, MPEG-2 and other standards. Nero Digital™ Video and Nero Digi-

Multithreading
Multithreading refers to a processor's capability of processing several tasks simultaneously.
In the field of software, it also refers to the distribution of computing work for a certain task
among several processors.
P-frame
P-frames (predicted frames) refer to predicted pictures in MPEG compression. They are ba-
sed on predictions and guesses from previous intra-frames (I-frames) and P-frames. They
only include the change information in comparison the the previous frame. Since P-frames
feature a higher compression ratio than I-frames, the compressed data volume is smaller,
since only the changes are saved in the frame.
Streaming
Streaming refers to the continuous transmission of data that can already be played during
the transmission procedure. This means that it is not necessary to wait until a media file has
been transmitted completely before it can be played back. A TV channel can be received
and displayed at the same time without it first having to be saved to the hard drive.
