High definition media storage structure and playback mechanism
View Patent ↗An apparatus and method for storing and playing high definition content is disclosed. This invention provides a mechanism for storing and playing back high definition content on a medium such as DVD optical disc. One aspect of the invention is that elementary streams may be multiplexed and processed in a high definition media player instead of at authoring time. Another aspect of the invention is that it provides for extended real-time features such as inserting watermarks into the content stream, decrypting selected sections of the content stream, and performing trick playback display modes.
1. An apparatus for playing high definition content comprising:
(a) a media player for receiving the high definition content from a media source, said high definition content contained in data packets and said data packets contained in sectors;
(b) a content processor for processing said high definition content into transport packets, said content processor further includes a trick mode generator, wherein said trick mode generator can create a pause effect by iteratively inserting into the video elementary stream a sequence comprising:
(i) an intra-coded picture frame; and
(ii) a multitude of predictive frames;
(c) a transport packet modulator for modulating said transport packets; and
(d) a controller.
2. An apparatus for playing high definition content comprising:
(a) a media player for receiving the high definition content from a media source, said high definition content contained in data packets and said data packets contained in sectors;
(b) a content processor for processing said high definition content into transport packets;
(c) a transport packet modulator for modulating said transport packets;
(d) a controller; and
(e) an HD-TV comprising:
(i) a decrypter;
(ii) a demultiplexer,
(iii) a watermark buffer for receiving watermark data;
(iv) a video buffer for receiving video data; and
(v) a watermark inserter for inserting watermarks into the video data, determined by the video data and watermark data.
3. A method for playing high definition content comprising:
(a) receiving the high definition content from a media source, said high definition content contained in data packets and said data packets contained in sectors;
(b) processing said high definition content into transport packets by;
(i) buffering received watermark data;
(ii) buffering received video data;
(iii) buffering received audio data;
(iv) inserting watermarks into the video data, determined by the video data and watermark data; and
(v) generating transport packets;
(c) modulating said transport packets; and
(d) outputting the modulated transport packets.
4. The method according to claim 3 , wherein said step inserting watermarks into the video data, determined by the video data and watermark data further comprises inserting a watermark into said video data by replacing a watermark marker in said video data with a watermark determined by information in a corresponding watermark data sector in said watermark data.
5. The method according to claim 3 , wherein said step inserting watermarks into the video data, determined by the video data and watermark data further includes inserting watermarks into specific locations in said video data determined by frame offsets, and presentation time stamps in said watermark data.
6. A method for playing high definition content comprising:
(a) receiving the high definition content from a media source, said high definition content contained in data packets and said data packets contained in sectors;
(b) processing said high definition content into transport packets by generating a pause effect by iteratively inserting into the video elementary stream a sequence comprising:
(i) an Intra-coded picture frame; and
(ii) a multitude of predictive frames;
(c) modulating said transport packets; and
(d) outputting the modulated transport packets.
