Abstract
The present invention relates to a method and an apparatus for reproducing content on interactive DVD by using a portable storage. The enhanced navigation data designated for interactive playback of content recorded in a recording medium is received from a server connected to a network. When the received enhanced navigation data are stored in an auxiliary storage such as USB memory removable from playback apparatuses, the content of the recording medium and the enhanced navigation data of the auxiliary storage are made associated with each other by recording information for linking the enhanced navigation data with the content additionally into the auxiliary storage.
Claims24
A recording medium, comprising:
- a content including at least video data;
- and
- navigation data having information for playback and/or searching the content,
- wherein the navigation data includes information for identifying the content.
A removable data storage medium, comprising:
- a storage area for storing enhanced navigation data having additional information for a content recorded in another medium,
- wherein a file structure for linking the enhanced navigation data with the content is recorded in the storage area.
A method for a player to reproduce a content recorded on a recording medium, comprising:
- receiving enhanced navigation data for interactive playback of the content from a server connected to a network;
- storing the received enhanced navigation data into an auxiliary storage connected in a removable manner to the player;
- and
- recording information for identifying the content into the auxiliary storage to link the content on the recording medium with the enhanced navigation data in the auxiliary storage.
A method for a player to reproduce a content recorded on a recording medium, comprising:
- receiving enhanced navigation data for interactive playback of the content from a server connected to a network;
- and
- storing the received enhanced navigation data into an auxiliary storage connected in a removable manner to the player,
- wherein the enhanced navigation data is stored such that a file structure accommodating the enhanced navigation data links the enhanced navigation data with the content.
A method for a player to reproduce a content recorded on a recording medium, comprising:
- reading identifying information of a content recorded on the recording medium;
- checking whether enhanced navigation data linked with the read identifying information is stored in an auxiliary storage connected in a removable manner to the player;
- and
- reproducing the content based on the enhanced navigation data stored in the auxiliary storage, if stored.
An apparatus reproducing a content recorded on a recording medium, comprising:
- a playback unit for reading and decoding the recorded content;
- an interface unit, connected to an external network and an external device, for communicating data;
- and
- a controller that checks whether an auxiliary storage is attached through the interface unit, obtains enhanced navigation data for the content if connected, and stores the enhanced navigation data into the auxiliary storage along with information for linking the enhanced navigation data with the content, or controls the playback unit to reproduce the content based on the enhanced navigation data in the auxiliary storage.
