AVCREC

Presently, AVCREC is tightly integrated with ISDB broadcast standard and is not marketed outside Japan.

AVCREC was defined in 2007 as the means of recording of high definition ISDB broadcasts on existing DVD recordable discs.

In the so-called DR mode a recorder does not re-compress the incoming signal, fully preserving the original quality of a broadcast program.

Some devices offer "long play" modes with compression up to 5x higher than original signal, with corresponding loss of quality.

MPEG4/AVC is usually used for "long play" modes as a more effective compression scheme compared to MPEG-2.
