METHOD OF CREATING VOBU IN HD-DVD SYSTEM

摘要

Disclosed is a method of creating video object units (VOBU) in high-definition DVD (HD-DVD)systems. HD enhanced data in the form of data packets are multiplexe d and stored with standard-definition (SD) data in a VOBU. In the VOBU, the spa ce where the video pocket (V-PCK) and the for SD data related video packet (V-P CK-HD) for HD-enhanced data are stored is shortened as possible. This will incre ase the efficiency of a future enhanced DVD video player that supports the HD-DV D optical disc format to fetch, decode and synchronize the SD and HD enhanced da ta. Furthermore, the optical disc created in this kind of data storing has good backward compatibility.
