杜比数字刻录技术英文介绍

With the advent of integrated DVD recorder/player components and high-capacity personal video recorders (PVR), it's easier than ever to archive your home movies and TV shows to recordable DVDs. And we've adapted our technology to help you get the maximum value and utility from DVDs you record.

Dolby Digital Recording is a highly sophisticated and efficient perceptual audio coding technology that formats any stereo audio content, such as a home-movie soundtrack, into a stereo Dolby Digital bitstream. So you can record any program's audio in high-quality, fully compatible stereo. Dolby Digital Recording is also a natural selection for DVD-based camcorders, in which the combination of audio and video quality (and often the length of recording, too) is an important consideration.

And, while retaining the quality and integrity of the original audio performance, it can also save up to 25 percent in overall disc space*. This space savings can used to make longer recordings or use a higher video bit rate to ensure the best-quality picture.

DVDs produced with Dolby Digital Recording will play back on any DVD-Video player that's compatible with recordable DVD media and the local TV standard of the player ?NTSC in North America and PAL in Great Britain.

* This assumes Dolby Digital Recording at a 192 kbps data rate on a fixed- or variable-bit-rate recorder and with a typical DVD disc at a fixed bit rate of 4.5 Mbps.
