Definitions

  • the invention relates to associating multiple media streams (possibly found in packages containing multiple DVDs), with their disposition within such packages, with the effect of allowing a user to conveniently and naturally select those media streams, and present or resume presentation of those media streams, or an appropriate media stream thereof, without the user needing to know the disposition of those media streams within those packages.
  • a single DVD might include multiple selectable content chunks for presentation, of which the user conveniently and naturally selects and views their choice thereof.
  • a DVD package containing multiple discs might collectively include a single selectable content chunk for presentation, which the user conveniently and naturally selects and views as a unit.
  • DVDs When DVDs are created, they might have more than one media stream written onto the physical media. This can occur in one of several ways.
  • this might include an introduction or a set of previews, a feature presentation, a set of credits, a set of out-takes, or a trailer for the feature presentation.
  • this might include a set of additional information about the characters, actors, or special effects, a set of video games, or a set of educational material.
  • this might include a set of relatively short cartoon features, or other short media streams, which collectively fit onto a single DVD, or for example, not intended to be limiting in any way, a set of four Abbott and Costello full-length movies on a single double-sided DVD.
  • this might include a sequence of episodes of a television series, or other series, which have been collected for sale on a single DVD or a set of multiple DVDs.
  • DVDs When DVDs are created, some media streams might be too large for a single item of physical media. This can occur in one of several ways. For an example, not intended to be limiting in any way, a media stream representing a movie might run longer than can be written onto one side of a DVD. There are some DVDs in which data representing media streams is written so, with the effect that a single movie can be fitted onto a single physical DVD, but with the drawback that the movie is split into two portions, one for each side of the DVD.
  • a collection of media streams such as a set of associated movies or a set of associated episodes of a television series, might be written onto multiple DVDs for sale as a set.
  • the number of distinct media streams actually written onto each individual DVD (or side of a DVD) can vary widely in response to the size of those media streams (and the size of any additional information).
  • a collection of movies such as a set of Oscar nominees for 2004, might be grouped into a set of multiple DVDs for sale as a set.
  • a collection of television episodes either spanning a single season, or spanning an entire run of that television show, might be grouped into a set of multiple DVDs for sale as a set.
  • presentation of a media stream involves selecting the DVDs associated with that media stream.
  • use of the set of multiple DVDs still involves selecting one of a relatively large number of media streams for presentation.
  • watching a single media stream that spans both sides of a DVD involves manually manipulating the DVD in the middle of the presentation (such as for example extracting the DVD, flipping it over, and reinserting it into the system), with the effect of breaking the flow of presentation.
  • watching a single media stream that spans more than one DVD involves physically manipulating both the first DVD and the second DVD.
  • the invention provides a method and system capable of associating multiple media streams (such as for example, possibly found in packages containing more than one DVD), with their dispositions within such packages.
  • a user can conveniently and naturally select, present, and resume presentation of, content chunks without the user needing to know the disposition of those content chunks within those packages.
  • the system associates content chunks, which may or may not be selectable, with media objects (including either physical media or otherwise stored digital content), and dispositions therein, without necessarily burdening the viewer with that association.
  • the system includes a database (the "content database") maintaining those associations, that is, which content chunks are associated with which particular media objects, and their dispositions within those media objects, and which media objects are associated with (contain a part of) each particular content chunk.
  • This content database might include information that associates multiple media objects with a particular content chunk, or information that associates one particular media object with multiple content chunks.
  • each media object is associated with a unique media hash value, with the effect that the content database can be optimized by associating content chunks in part with media hash values (rather than actual media objects).
  • the content database includes at least a portion that is constructed relatively remotely from a home entertainment system, which portion is cached or downloaded to the home entertainment system. This has the effect that the home entertainment system has a local content database with the appropriate content database information available when attempting to display, present, or resume presentation of, content chunks media objects.
  • some alternative embodiments may differ.

  • a content chunk might be or include a feature-length movie.
  • a particular content chunk might or might not be independently selectable for presentation, and might also include other content chunks that may be or may not be also independently selectable for presentation.
  • a content chunk might be or include one or more of the following.
  • a content chunk might be or include a feature-length movie, a set of previews, a trailer for that movie, a set of "chapters" for that movie (with the effect that the viewer can skip to a selected bookmark in the movie), a set of credits, a set of out-takes or bonus scenes for that movie, a set of associated other material for that movie, a combination of some or all of the above, and the like.
  • That associated other material might include promotional material such as posters or music videos, video games, a set of "behind the scenes” material, and the like.
  • a content chunk might be or include an entire season of a television series, an individual episode of that season, and the like.
  • a content chunk might be or include a set of presentable (favorite) scenes (such as film clips containing each of the famous lines in the movie "Casablanca”), possibly manufactured by an owner or distributor of the original content, possibly manufactured by the viewer using bookmarks or watchpoints, or possibly manufactured by a third party (such as a distributor of horror movies manufacturing a compilation of all the fright scenes in Oscar- winning movies).

  • a content chunk might be or include multiple versions of a movie, likely to be alternative versions, such as multiple versions differing by sound track or video format or by widescreen versus pan-and-scan. Such multiple versions might also include a standard version and a "director's cut”.
  • a content chunk might be the content on a package of DVDs (or other physical media, or other downloadable content) sold as a unit.
  • a (selectable) content chunk might span more than one media object, without the viewer necessarily having any idea of that fact.
  • a (selectable) content chunk might switch back and forth among multiple media objects, again without the viewer necessarily having any idea of that fact.
  • Selectable content chunks might also have associated user-accessible metadata with them: such as title, actors, directors, cover art, and the like.
  • a viewer may ask to see more detailed information about a particular selectable content chunk. This allows the viewer to see information about content chunks included within that particular selected content chunk.
  • selectable content chunks included in the particular selected content chunk might be organized for the convenience of the user, such as for example for ease of manipulation involving a user interface.
  • multiple content chunks may be associated with each other, such as for example, grouped together in a set, to form a single content chunk that might be selected or manipulated by the user.
  • substantially all of the content chunks associated with the media objects included in a DVD package are included within the content chunk associated with that whole
  • DVD package This has the effect that the viewer has a substantially more manageable number of choices within a menu of choices related to that DVD package, rather than the likely rather large number of choices that would be afforded if each and every possible content chunk were presented, with the user interface, at once as a selectable content chunk.
  • Another example might occur in the event that one or more DVDs include several related episodes (e.g., of a TV show). In such events, a single content chunk might contain such episodes ordered substantially sequentially without any need to navigate a DVD menu.
  • this aspect of the invention includes at least some of the following capabilities provided to the viewer.
  • selection refers to those content chunks that are the primary unit of organization in the user interface. Thus a selection is a content chunk, which usually contains multiple other selectable content chunks.
  • the viewer's user interface displays a set of elements that represent selections. These elements may by rows or icons, as described in the following two related patent applications. o International patent application no. PCT/US2004/000367 (Kaleidescape, Inc.), "Grid-Like Guided User Interface for Video Selection and Display,” filed on 8 January 2004 and published on 29 July 2004 under publication number WO 2004/064372 A.
  • the system when a viewer selects a selection, the system might present that selection (or one of the sub-content chunks within that selection).
  • the user interface when a viewer selects a selection, the user interface might present multiple elements of text or icon, as described in the two related patent applications, each such element of text or icon being associated with one or more selectable content chunks within the selection.
  • the number of selections in the system is substantially less than the number of individual (selectable) content chunks, as each selection likely contains at least three selectable content chunks (such as for example: a feature, a trailer, and the entire media object).
  • Selections might represent only certain selectable content chunks such as the collection of media streams associated with a particular "movie" or there could be selection in some or all views of the viewer user interface that represent individual content chunks associated with a movie.
  • Selections can represent individual episodes or movie clips, or collections of feature movies or sequences of film clips, or favorite scenes, episodes, songs, play-lists, or any other kind of content chunk. • A viewer may sort, search, and otherwise manage their collection by manipulating the attributes associated with each selection.
  • the terms “play”, “playback”, “present”, “presentation”, and the like refer to presenting (sometimes herein referred to as “playback") of a content chunk, with the effect that a viewer or listener might access the media stream represented by the digital data included in that content chunk.
  • a feature length movie might be “played” or “presented”, as if in a theater.
  • a concert or symphony might be “played” or “presented”, as if on a sound system.
  • These terms are intended to be broad enough to include all manner of human sensation.
  • present is sometimes used herein for data, icons, or other information presented through the user interface, hi the event of that usage, the user interface is either explicitly mentioned, or it would be clear from context to those skilled in the art.
  • the user can, for any selection, choose to view more detailed information about it. This causes the presentation, with the user interface, of enhanced metadata for the selection and allows the user to explicitly choose a specific content chunk within, or associated to, that selection, to present.
  • selectable content chunk includes content chunks for episodes within the selectable content chunk
  • those content chunks for episodes might be grouped under an "episodes" sub-heading.
  • the selectable content chunk consists of a sequence of favorite scenes
  • asking for more detailed information might cause it to be broken down into individual selectable content chunks, each of which is a favorite scene.
  • the system might respond with the effect of causing the package to "expand" to a family of selectable content chunks, each corresponding to an individual DVD.
  • the display of this information may be affected by parental control restrictions. For example, under various circumstances, one might suppress display of information about some but not all content chunks within a content chunk.
  • a viewer might select a particular selectable content chunk and ask for it to be "played". That is, the view might ask for a media stream appropriate to that selected content chunk to be presented.
  • This media stream to be presented may omit several minutes of advertisements that the viewer must watch when playing the corresponding DVD disc with a DVD player.
  • the media stream to be presented may omit the need for any interaction by the viewer with the DVD menu.
  • the system does what the viewer "really wants”. That is, the user may really want to see a preview of a large content chunk, such as for example, to see what it looks like, rather than immediately playing it.
  • a viewer might be presented, through the user interface, with multiple ways of playing a selectable content chunk, such as to either to play all episodes or to play the first episode.
  • the viewer might select a selectable content chunk containing multiple smaller content chunks.
  • the system would then, without any further interaction with the viewer, "play it all” by presenting all those smaller content chunks in sequence, that is, "one touch presentation”.
  • requesting play of a playable content chunk (that is, a content chunk capable of being presented to the user) such as a collection will use a play-list of clips from the content chunks within the collection. That is, playing this collection content chunk causes the presentation not of the concatenation of the content chunks in the collection, which could take days, but instead causes the presentation of the concatenation of certain much smaller content chunks, namely representative film clips, contained in the content chunks in the collection.
  • the content database might define a content chunk substantially subsidiary to (such as substantially one included in, or included in a trailer related to) each large content chunk, so that playing that large content chunk, or a content chunk containing that large content chunk, would cause the presentation of the subsidiary content chunk in place of the content chunk itself. This might happen even though the subsidiary content chunk might be independently playable or selectable.
  • a defined subsidiary to each content chunk one could use search criteria to define a collection in real time, and request the playing of this collection; this would cause the presentation of the concatenated sequence of content chunks subsidiary to the content chunks in the collection.
  • requesting the play of a content chunk corresponding to a physical package containing multiple DVDs might cause the first DVD to play or it might cause the presentation of feature presentation on the "first" DVD.
  • requesting the play of a content chunk including multiple versions of a movie could cause either presentation of the user-preferred version or the offer of a choice.
  • the action taken by the system when the user requests the playing of a content chunk is designed to be that which the user "really wants". For example, the user may really want to see a preview of the large content chunk, or what the large content chunk looks like, rather than really playing the whole thing. In general, the system interprets this by sometimes presenting default subsidiary content chunks rather than the content chunks themselves.
  • resume information can be stored with some or all selectable content chunks that contain the just presented content chunk. In alternative embodiments, resume information may be stored only with the smallest selectable content chunk that contains the content chunk that was just presented.
  • Such an ordering might be for example according to the dates on which the content chunks were first released on television or at the cinema. • Determining the last-watched position in a content chunk such as a feature movie is relatively simple. However, it is more complicated for a content chunk such as a series of episodes. Default configuration and user preferences are used to determine where a series of episodes is resumed (when, for example, the first episode has been watched, the second has not been watched, and five minutes of the third episode has been watched. This determination could be in response to user input, to detection of multiple viewers, to user preferences or profile, to staleness or the amount of time elapsed since previous views, to quantity watched and not watched.

  • the system begins presentation of all episodes in sequence.
  • the system selects the most appropriate such feature presentation content chunk for this viewer and presentation device (in response to at least one of: aspect ratio; parental control rating; resolution, that is, standard definition versus high definition) and begins presentation of that selected feature presentation content chunk.
  • the system selects the most appropriate trailer content chunk for this viewer and presentation device, in response to similar considerations, and begins presentation of that selected trailer content chunks. • Otherwise, in the event that the selectable content chunk includes a DVD disc content chunk, the system selects the first such content chunk and begins playback of that first such content chunk.
  • “best,” that is, the most likely to be preferred, choice for the viewer possibly in response to at least one of the following. (1) which multiple viewers, including possibly how many such multiple viewers, are in the range of the presentation device, (2) the location of the presentation device, (3) demographic or viewing preference information about the viewer(s), whether expressed explicitly or implicitly, (4) how long it has been since the viewer(s) presented or viewed that selectable content chunk, or smaller content chunks included in the selectable content chunk, if the viewer(s) interrupted presentation, and if so, for what reason the viewer(s) did so.
  • one touch presentation of a given selectable content chunk includes a technique with the effect that a most appropriate presentation option for that viewer is selected.

For an example, not intended to be limiting in any way, the user might select a content chunk and in response be presented, through the user interface, with a set of associated selectable content chunks. This would have the effect that the user could select one of the associated content chunks at each level, until a monolithic selectable and presentable content chunk was available.

Abstract

L'invention a pour but d'associer de multiples segments de contenu à de multiples ensembles de DVD ou objets multimédia; de visualiser commodément ou reprendre ces segments de contenu sans connaître leur disposition; d'associer des segments de contenu à des objets multimédia et des positions dans lesdits objets; et d'associer à des comportements appropriés, y compris une base de données, les requêtes d'un utilisateur de lecture ou de reprise de la lecture. Les objets multimédia ont des valeurs uniques de hachage, pour associer des segments de contenu à des valeurs de hachage, et des positions dans les objets multimédia conservées par des signets et des points d'arrêt. Sélectionner un segment de contenu peut entraîner que ses métadonnées soient présentées ou peut entraîner que des segments de contenu sélectionnables dans ce contenu deviennent sélectionnables. Des utilisateurs demandant la lecture ou la reprise de la lecture de segments de contenu peuvent provoquer la présentation de ces segments de contenu ou de segments de contenu plus petits, tels des films. Les segments de contenu peuvent englober plusieurs objets multimédia ou on peut commuter dans les deux sens entre de multiples objets multimédia, et ce sans que le spectateur en soit nécessairement averti.
