[0001] This application claims priority to “Method and
System for a Blu-Ray/HD-DVD Chip”, Provisional Appli
cation for US. Patent Ser. No. 60/863,509, ?led Oct. 30,
2006.
[0002] This application is also related to US. application

[0003] Each of the above stated applications is hereby
incorporated herein by reference in their entirety.
BACKGROUND OF THE INVENTION
soundtrack on a disc. For lossless audio in movies in the
PCM, Dolby TrueHD or DTS-HD formats, HD-DVD discs
may support encoding of up to 24-bit/ 192 kHZ for tWo
channels or of up to 24-bit/96 kHZ encoding for eight
channels.
[0007] The emergence of tWo competing standards poses
compatibility problems for playback systems. For example,
a playback system that plays back HD-DVD discs may not
play back Blu-ray discs. Similarly, a playback system that
plays back Blu-ray discs may not play back HD-DVD discs.
[0008] Further limitations and disadvantages of conven
tional and traditional approaches Will become apparent to
one of skill in the art, through comparison of such systems

HD-DVD chip, substantially as shoWn in and/or described in
magnetic recording, for example. Recent developments con
tinue to expand the capabilities of optical disks by enabling
higher data storage capacity Within a single disk. For
example, Blu-ray optical disk technology may utiliZe blue
lasers to read and Write to the disc. A Blu-ray disc may store
substantially more data than, for example, a digital versatile
disk (DVD) or a compact disk (CD), because of the shorter
Wavelength, approximately 405 nm, of the blue laser com
pared to the 650 nm Wavelength for red lasers used by DVDs
and the 780 nm Wavelength for infrared lasers used by CDs.

With an embodiment of the present invention. The integrated
circuit comprises a host processor 101, a transport processor
103, a still image decoder 301, a security circuit 303, and an
audio decoder circuitry 305.
[0021] The transport processor 103 is capable of parsing
both Blu-ray and HD-DVD media. The still image decoder
301 is capable of decoding still images for both Blu-ray and
HD-DVD. The security circuit 303 is capable of decrypting
both Blu-ray and HD-DVD media. The audio decoder
circuitry 305 is capable of decoding audio media from both
Blu-ray and HD-DVD media. The host processor 101 con
?gures the transport processor 103, still image decoder 301,
security circuit 303 and the audio decoder circuitry 305
based on Whether a received media stream is Blu-ray or
HD-DVD.

Video Decoder
[0029] The video decoder 450 decodes video elementary
streams provided by the video queue 120v. The video
decoder 450 can transition from one selected video elemen

invention, the video decoder 450 is operable to detect a
marker indicating a change of selected video elementary
stream in the video queue 120v. Responsive thereto, the
video decoder 450 changes the codec associated With the
previously selected video elementary stream to a codec
associated With the neWly selected video elementary stream.
In certain embodiments, the arrival of the marker at the
video decoder 450 can cause an interrupt. The interrupt can
cause the video decoder 450 to sWitch to the appropriate
codec.

The video decoder 450 can be equipped With
codecs to decode video data compressed in accordance With
Advanced Video Coding (AVC, also knoWn as H.264, and
MPEG-4, Part 10), SMPTE VC-l Advanced Pro?le Level 4,
SMPTE VC-l Simple Pro?le to Medium Level, and SMPTE
VC-l Main Pro?le to High Level. The video decoder 450
can be capable of simultaneous single high de?nition and
