摘要:
Enhanced multimedia content on physical media interacts with the user through a media player and the Internet. Enhanced multimedia utilizes IDs for pieces of content on the media and a media key block. On the enhanced media is a file with a list of URLs. As the enhanced media plays a title requiring an external permission for decryption, the media player accesses the URL for that title and obtains the permission. The permission may be purchased or provided for free. Secure encryption and transmission of permission is accomplished by broadcast encryption using a media key block. Each media has a unique set of keys that allow the media player to process the media key block; however, each media follows a unique path through the media key block. All legitimate media players obtain the media key; circumvention devices cannot decipher the media key block.

摘要:
A media (e.g., Blu-Ray) first content package includes a link to an application for sending second content to a remote device, especially a mobile telephone. The application is included in the first content. The second content is not included in the first content. The application presents a list of second content choices, selectable by a user. The application receives a destination address for the second content from user input and sends the destination address to a second content server. The second content server contacts the remote device having the indicated destination address, and confirms that receipt of second content will be accepted. Upon receiving confirmation, the second content server transmits the second content to the remote device. The technology may be used to provide content to mobile devices, such as mobile phones, in association with distributed media such as Blu-Ray discs configured for being played by a media player.
摘要:
Disc burner software is known that generates only a second generation disc from an original or first generation disc by adding to the second generation a copy protection indication. According to the present invention, an original disc includes normal program files, and in addition, also includes the copy protection indication. When an attempt is made to copy such a disc using the disc burner software, the software will not make a second generation copy because it will mistakenly identify the original disc as a copy.

摘要:
A disc burner receives a disc to be copied and checks whether it is an original disc or a recordable disc. If it is an original disc, its contents are copied with a copy protection indication. If it is a recordable disc, a check is performed to determine if it has a copy protection indication and copying is performed only if allowed by said copy protection indication.

A specification defining allowable luma and chroma code-values is applied in a region-of-interest encoding method of a mezzanine compression process. The method may include analyzing an input image to determine regions or areas within each image frame that contain code-values that are near allowable limits as specified by the specification. In addition, the region-of-interest method may comprise then compressing those regions with higher precision than the other regions of the image that do not have code-values that are close to the legal limits.

Seamless navigation is provided between high-definition audio-video content configured for use with a media player application, and an executable video game packaged with the audio-video content on a digital medium. An API module is distributed to player/consoles. An application provided with the high-definition audio-video content detects the presence of the API module on the player device. In response to detecting the API module, the application provides an interactive feature that uses the API module to load and execute the executable video game in response to user input.
摘要:
A content media such as a disc is disclosed having a portion with content in one format and a second portion with information in a second format. Typically, the first format may not be compatible with some (usually early) disc players. If a user inserts the disc into an incompatible disc player, the disc player reads the information from the second portion and generates a message to that effect to the user. The message may be a voice message, a text message, an image, etc. In an alternate embodiment, a disc with content in two formats is provided on a disc and the player either plays one of the two formats depending on a default setting, or plays one of the formats in response to a selection by the user
