Embodiment Construction

[0050] now refer to figure 1 , shows a block diagram of a typical integrated circuit according to one embodiment of the present invention. The integrated circuit includes a main processor 101 , a transport processor 103 and a disk interface 105 . The integrated circuit may be connected to the optical disk drive 107 and the memory 105 . Under the control of host processor 101, disc interface 105 enables media streams to be transferred from optical disc drive 107 to memory 105, wherein the media streams are either in Blu-ray format or HD DVD format. The transport processor 103 reads the media stream from the memory 105 . Based on the type of media stream received, the host processor 101 configures the transport processor 103 to parse the media stream.

[0051] Note that the Blu-ray format uses transport stream packets, while the HD DVD format uses program stream packets. Thus, if the media is in Blu-ray format, the host processor 101 can configure the transport processor 103...

Abstract

The integrated circuit comprises a transport processor and a host processor. The transport processor parses a media stream. The host processor determines whether a media stream is Blu-ray or HD-DVD and configures the transport processor based on whether the media stream is Blu-ray or HD-DVD.

Description

Background technique [0001] With the development of optical disc technology, larger amounts of audio and / or video data can be stored on a single disc than other technologies such as magnetic recording. Recent technological developments have enabled higher data storage capacities within a single disc, continuing to expand the capacity of optical discs. Blu-ray disc technology, for example, uses blue laser light to read and write to the disc. A Blu-ray Disc can store more data than, for example, a Digital Versatile Disc (DVD) or a Compact Disc (CD) because the blue laser has a wavelength of Has a shorter wavelength, about 405nm. The use of shorter wavelengths allows more information to be stored digitally in the same amount of space. Blu-ray technology can store more information capacity on a single disc layer than High Definition Digital Versatile Disc (HD DVD), which also uses blue lasers. [0002] The emergence of two competing standards has caused compatibility problems ...
