Panasonic has been authoring DVDs in the U.S. since 1996. In order to provide the new service, Panasonic has installed Blu-ray Disc authoring equipment at PHL. The equipment installed for this purpose includes a specially developed MPEG-4 Advanced Video Codec (AVC) encoder and a Blu-ray Java authoring system.
The combination of the encoder and authoring system enables Blu-ray title creators to reproduce near-original, high-quality video with an easy-to-use graphical user interface (GUI) based on Java. The new Panasonic encoder and authoring system support the Blu-ray Disc Association's BD-ROM specification, and take advantage of the disc's benefits including very high data compression, interactive menus and highly advanced copyright protection.
The Panasonic MPEG-4 AVC encoder, capable of more than twice the compression of conventional MPEG-2 encoding, maintains the highest- resolution 1080p image quality of the source. The BD-Java authoring system offers a variety of interactive features such as pop-up menus, allowing for easy content navigation during playback. For example, users can pop up a table of contents during playback, bookmark favorite scenes, or select any desired item from the menu.
