Copying digital content by emulating playing of a recording medium by a player

A method of copying content from a recording medium carrying content data and navigational command data that determines the order in which a player of the recording medium will access the content data, the method comprising:

• Accessing locations of the recording medium by a reader to read content data and navigation data from the recording medium;
• executing a navigation command by a navigator in accordance with navigation data read by the reader;
• controlling by a controller the location of the recording medium accessed by the reader by emulating a player of the recording medium in accordance with the execution of conditional navigation commands by the navigator so as to cause the reader to follow all navigation paths through the content data defined by the navigation data that are related to player action or user menu selection;
• and
• the controller storing, by a presentation data storer, content data for recording onto a recording medium the corresponding data for enabling recording of the content data for the navigational paths.

A method of producing a digital copy of digital content carried by a DVD, the method comprising:

• 1) a processor executing a command of a first play program chain within a video manager information of the DVD;
• 2) the processor accessing a destination program chain defined by the first play program chain;
• 3) the processor executing a pre-command for the destination program chain;
• 4) recording, or recording a location of, on a recording medium presentation data to be accessed by the navigation sequence during the execution of the destination program chain;
• 5) the processor executing a post-command for the destination program chain and, in the event that post-command leads to a further program chain, executing a pre-command for that further program chain, recording, or recording a location of, presentation data to be accessed during the execution of that further program chain, and executing a post-command for that further program chain;
• 6) repeating 5) until a post-command returns to a user options menu;
• and
• 7) in the event a user selects a menu option, repeating 1) to 6) until no further menu options are selected or are available, wherein the method emulates a player of the recording medium to follow all navigation paths through the presentation data that are related to player action or the user menu options.

A non-transitory storage medium storing processor-implementable instructions to cause a processor:

• 1) to execute a command of a first play program chain within video manager information of the DVD;
• 2) to access a destination program chain defined by the first play program chain;
• 3) to execute a pre-command for the destination program chain;
• 4) to record, or record a location of, presentation data to be accessed by the navigation sequence during the execution of the destination program chain;
• 5) to execute a post-command for the destination program chain and, in the event that the post-command leads to a further program chain, to execute a pre-command for that further program chain, to record, or record a location of, presentation data to be accessed during the execution of that further program chain, and to execute a post-command for that further program chain;
• 6) to repeat 5) until a post-command returns to a user options menu;
• and
• 7) in the event a user selects a menu option, to repeat 1) to 6) until no further menu options are selected or are available, wherein the method emulates a player of the recording medium to follow all navigation paths through the presentation data that are related to player action or the user menu options.
