The present embodiments provide methods and apparatuses for use in navigating through content. Some embodiments provide methods for use in navigating through content that receive an initial first directional control command, activate a seek mode upon receipt of the initial first directional control command comprising advancing over a first amount of content in a first direction from a first point in the content to a second point in the content, receive an initial second directional control command following the receipt of the initial first directional command, and activate a search mode upon receipt of the initial second directional control command, comprising advancing back over a second amount of the first amount of the content where the second amount is less than the first amount of the content.

Adaptive intervals in navigating content and/or media

The present embodiments provide methods, apparatuses, and systems for use in maintaining data quality upon conversion to a different data format. Some embodiments provide methods that receive media data in a first format, initiate a first conversion of the media data at the first format to a second converted format, identify parameters dictating the conversion to the second converted format, record the parameters, and distribute the recorded parameters to remote systems such that the parameters at least in part control the remote systems during a conversion of the media data to the second converted format.

Methods and systems for use in maintaining media data quality upon conversion to a different data format

The present invention relates to improvements in the generation of an authoring file, readable by an authoring program of a DVD-Video or other interaction video media, that defines the playback structure of the content residing in a given disc's 'authored content zone' and also defines the location of the assets that make up the disc's 'presentation data.' The improvements allow generation of an authoring file that references assets that are within the authored content zone of the medium. This allows the authoring &#x201c;project&#x201d; from which the final DVD-Video disc image was created to be reopened in a compatible authoring program&#x2014;and to be modified by such a program&#x2014;without reference to any of the original source materials.

Interactive media authoring without access to original source material

The invention relates generally to improvements in systems used in the development ('authoring') of interactive visual media. More particularly, the invention relates to (a) the automatic or semi-automatic generation of a set of files representing 'zoomed-in' sections of a master high-resolution image file, and (b) the automatic or semi-automatic generation of the logical data required to allow navigation of the generated files by an end-user of an interactive visual medium, including but not limited to such optical disc formats as DVD-Video, DVD-Audio, Video CD, and Super Video CD, as well as media hosted by a server and delivered over a network.

End-user-navigable set of zoomed-in images derived from a high-resolution master image

An authoring file, readable by DVD-Video authoring program, defines the playback structure of the DVD-Video material residing in a given disc's 'DVD-Video zone' (VIDEO_TS directory) and also defines the location of the assets that make up the disc&#x2014;s DVD-Video 'presentation data.' The efficiency with which a DVD-Video title stored on a rewritable disc (e.g. DVD-RW, DVD+RW, DVD-RAM, or CD-RW) that has been revised in a compatible software applicaiton may be written back to that same disc is optimized. The minimum amount of file rewriting required to effect the desired revisions to the project, in particular avoiding the rewriting of large VOB files, is determined.
