Generation loss

The term Generation loss refers to the increasing deterioration of quality ( copy ) generation to generation.

When making a copy errors occur. One made ​​by a copy that already has error, again a copy to, then propagates the old error on the next copy ( generation ), and it can also create new errors.

This generation losses are particularly in video and audio equipment a problem because they occur where both the analog dubbing on and in digital, provided there with no error-correcting data transmission protocols and using a lossless data compression ( = data reduction, see also audio data compression) is in progress.

This is especially problematic when a compressed through a lossy process file converted to another lossy format, ie is transcoded (eg an MP3 file to an AAC file).

Similarly with the lossy JPEG image compression, where the quality of the image data is reduced with frequent decompress, edit, and re- compressing part.
