Definitions

  • the invention generally relates to providing highlights for real time events, such as sporting events, and, more particularly, to acquiring statistics for real time events and using such statistics for identification of highlights.
  • reporting services typically condensed an event into a few highlights capturing activities the reporting service believed to summarize moments of interest within the event.
  • Such highlighting leads to another limitation: consumers are not able to control distribution of highlights.
  • the reporting service must provide highlights that are generally applicable to a broad consumer base, which potentially requires a consumer to view highlights of no interest to the consumer.
  • FIG. 1 illustrates one embodiment for acquiring and distributing an event's secondary data.
  • FIG. 2 illustrates one embodiment for acquiring an event's primary data and partitioning it with respect to FIG. 1 secondary data.
  • FIG. 3 illustrates distribution of new partitions through a distribution service.
  • FIG. 4 illustrates providing a highlight to a requesting client.
  • FIG. 5 illustrates a suitable computing environment in which certain aspects of the invention may be implemented.
  • the illustrated embodiments of the invention show exemplary systems and methods for obtaining event highlights contemporaneously with performance of an event.
  • primary data refers to a representation or encoding (e.g., analog or digital recording) of an event
  • secondary data refers to data (e.g., statistics or other data) associated with the event.
  • highlights are stored in a database or other data construct, and the database may be searched according to the associated secondary data.
  • FIG. 1 illustrates one embodiment for acquiring and distributing an event's secondary data.
  • the event is a sporting event
  • the secondary data is statistics compiled about the event during the event.
  • a first operation is to acquire 100 secondary data related to primary data.
  • a third-party data source is contacted.
  • This source may be a real- time data feed, such as from a courtside statistician entering data at a sporting event, or it may be a time delayed retrieval, such as real-time data that has been post- processed (e.g., corrected, synchronized with the event, etc.) before subsequent distribution.
  • Time delayed may also include retrieval from a database or other storage medium.
  • the acquired data may then be converted 102, if necessary, into another format for storage into a database or other storage format. It is assumed herein that the invention may be used to acquire secondary data from many different sources; and that these sources may each use their own encoding format for initially encoding the secondary data. In such circumstances where there are multiple encoding formats, it is assumed that all formats not already in a common (e.g., unitary) format are converted into the common format for storage.
  • the secondary data which may have been converted, is stored 104 in a database.
  • synchronization data is determined 106 and provided 108 to a partitioner (see FIG. 2), and stored 110 in the database along with the secondary data.
  • the synchronization data is used to cross-reference secondary data with primary data. Assuming secondary data is compiled contemporaneously with an event, in one embodiment, synchronization determination 106 includes identifying time stamps or other temporal markers to correlate a particular secondary data entry with the entry's corresponding primary data.
  • the primary data can be a digital recording (or other format) of the game.
  • the recording has explicit or implicit time markers tracking recording duration and/or time of day for game play.
  • the secondary data can be real-time statistics entered by a courtside statistician.
  • Statistic entries will have associated time markers for when the statistic was entered.
  • associated with these entries will be starting time and stopping time markers for the portion of the event relating to a particular statistic entry. For example, if a statistic concerns a three point shot, then the starting and stopping markers indicate, with respect to the primary data recording, where in the primary data recording that three point shot occurred.
  • a single time marker is used to mark the occurrence of a specific event, e.g., the three point shot. Starting and stopping markers can be determined later according to a variety of techniques.
  • rules can be used to set the starting and stopping time markers.
  • a rule applying a preset time window can be used.
  • the shot is assumed to occur 5 seconds prior to the statistic's time marker, and last for 5 seconds after the statistic entry.
  • a rule applying past experience with a statistic type can be used to set starting and stopping markers. For example, if it is known a certain occurrence type has a typical duration, then the rule can use this typical duration to set the starting and stopping markers.
  • a rule identifying significant statistics can be used to set or adjust (e.g., operating in conjunction with another rule) starting and stopping markers. For example, in a baseball game where a player has just set a new record for home runs, the significance of a new record may be used to adjust markers. Thus, if using the 5 seconds before/after statistic rule, set a stopping marker to 30 seconds after a statistic entry to account for more activity incident to the setting of a new record.
  • starting and stopping markers are manually cross- referenced with the primary data contemporaneous with recording the statistic.
  • video analysis or image / pattern recognition is used to automatically identify starting and stopping markers.
  • Both primary and secondary data markers may be localized, e.g., each starting at zero, or they may be based on a global clock, a standard atomic clock, or other timing technique, so long as they may be cross-referenced to each other.
  • FIG. 2 illustrates one embodiment for acquiring primary data for an event, and using synchronization data (from FIG. 1) to partition the primary data for distribution.
  • a first operation is to acquire 200 primary data, such as a camera input signal.
  • primary data such as a camera input signal.
  • input signal can be for a sporting event, such as a basketball game, however the input signal may also represent, for example, a play, opera, interactive game, or any other event having transactions that can be recorded in analog or digital format to a medium.
  • the acquired primary data is then converted 202, if necessary, into a digital format. Similar to acquiring 100 (FIG. 1) secondary data, such as statistics, related to the event, acquired primary data may be received in a variety of formats. All primary data is therefore converted, when needed, into a common unitary format. As will be discussed below, the unitary format may then be provided to a requesting client in a particular desired format. For example, a live performance may be captured by a recording camera, stored in the unitary format, and then later converted into a Moving Pictures Experts Group (MPEG), Nideo for Windows, Indeo, QuickTime, Windows Media Format, Real Media Format, or other data file for distribution to the client. (All marks used herein are the property of their respective owners.)
  • MPEG Moving Pictures Experts Group
  • the digital media file is then partitioned 204 in accordance with provided 108
  • FIG. 1 synchronization data. Partitioning is helpful in that it allows for quick distribution of data containing highlights, e.g., highlights can be made available contemporaneous with the action giving rise to the highlight. In addition, small sections of the primary data facilitate distribution of highlights.
  • the primary data for the event can be accessed while the primary data file is being written. As soon as a portion of the digital media file is recorded, but before the event is over and recording completes, the recorded portion of the digital media file may be used for distribution of highlights related to secondary data entries that have been cross-referenced to the partial digital media file. This allows distribution of highlights during the event for which the highlight was generated.
  • the restriction may be overcome by interleaving recording of the event into multiple primary data files. For example, recording in a first primary data file can occur until a certain end-point, such as a recording time limit, end of a partition, or other event. Then, recording of the first primary data file is closed, and simultaneously, a new recording in a second primary data file immediately started. In such fashion, the first completed primary data file may be processed.
  • a certain end-point such as a recording time limit, end of a partition, or other event.
  • each partition contains only a single highlight. In another embodiment, more than one highlight may be present within a given partition of the digital media file.
  • acquired secondary data has associated temporal markers, such as starting and stopping markers, that synchronize portions of the primary data to secondary data referencing the primary data, e.g., these markers indicate the portions of the primary data that are a highlight.
  • Multiple secondary data entries can refer to a single partition, thus allowing multiple highlights on a single partition, and multiple entries referring to a single highlight (e.g., broad and narrow statistical categories may refer to the same highlight). For example, a shot attempt, rebound and tip-in would generate several statistics all referencing the same partition.
  • partition contents overlap to ensure a highlight does not begin in one partition, and end in another partition. Overlap may occur when partition sizing requirements, such as fixed partition sizes, cause a highlight to be broken across multiple partitions.
  • portions of the primary data that are not referenced by a highlight are discarded.
  • density (or frequency) of synchronization data may be used to partition the primary data according to activity within the event. For example, using the above basketball game example, it can be assumed the statistician only enters statistics (secondary data) for noteworthy actions in the game. Based on this assumption, if many statistics are entered for a first portion of the game, then the primary data corresponding to that period will be partitioned into smaller (possibly overlapping) partitions. In the above example of a shot attempt, rebound and tip-in, these activities result in several statistics in a short period of time. In this embodiment, several highlights for these activities would be bundled within a single partition. Conversely, if no statistics are entered for a portion of the game, then primary-data for this portion of game can be discarded, or relegated to a single partition that is unlikely be downloaded since it contains no highlights.
  • partitioning results in separate data files.
  • partitioning can be logically effected using pointers referencing into a randomly accessible monolithic primary data file representing the event (or all highlights for the event).
  • a client request for a partition such as by a media access application program (see FIG. 4), can be resolved to offsets within the data file that define a virtual partition.
  • a distribution service would have the entire monolithic data file stored on its devices, and then determine and send the virtual partition in response to the client request.
  • various other partitioning schemes may be implemented through use of pointers to define virtual partitions.
  • the partition may be converted 206 into a different data format.
  • Conversion may be used when it is desired to pre-provide partition data in a variety of data formats, such as Microsoft's Audio Nideo Interleave (ANI) format, Apple's QuickTime format, Interactive Pictures Corporation's "IPIX" (360° data), MPEG, Nideo for Windows, Indeo, QuickTime, Windows Media Format, Real Media Format, three-dimensional encodings, or other audio and/or visual encoding formats.
  • Pre-provision can expedite delivery of content to requesting clients, as well as reduce load on a distribution service responsible for delivering the requested content. Conversion may be required if the primary data's digital format is not suited for distribution to requesting clients. For example, the primary data may be recorded in a non-standard format to facilitate partitioning of recorded event data.
  • a media catalog is notified 208 of the existence of the new partition.
  • the media catalog is responsible for recording 210, in a database or equivalent data construct, new partition creations.
  • the recording 210 of the new partition identifies the created partition, and this identification is cross-referenced 212 with the database entry (or entries) containing secondary data entry referencing the new partition.
  • Identification can be by way of partition name, storage location, file begin/end offsets within a data file, the start and stop time of the partition as synchronized to a global clock, or other uniquely identifying references.
  • One or more database records may be used to record a secondary data entry and associated creation notifications.
  • both secondary data and partitions are synchronized to a global clock to facilitate cross-referencing one to the other, and for searching for highlights within a particular partition.
  • the database entry for the recorded 210 partition creation is marked 214 as being unavailable, and submitted 216 to a distribution service for media distribution. Marking as unavailable allows for a lag time between partition creation, and actual availability to a requesting client device.

  • partitions are assigned a Uniform Resource Locator (URL) (or equivalent) address through which the new partition may be indirectly accessed through resolution of a database query which returns a file containing the partition's URL and offsets within the partition for accessing a particular highlight therein for playing by a client media access application such as a video player application commercially available from Microsoft Corporation or Real Networks, Inc.

Abstract

L'invention concerne la mise en évidence d'un évènement en même temps que l'occurrence de l'évènement dans un système client-serveur. Des données associées à l'évènement sont utilisées pour rechercher des moyens de mise en évidence particuliers. Par exemple, si l'évènement est une rencontre sportive, les données secondaires peuvent être des statistiques compilées au cours du jeu. Au fur et à mesure de sa progression, l'évènement est enregistré, et l'enregistrement est segmenté afin de faciliter sa distribution. Cette segmentation peut être basée sur la densité des données secondaires, de manière que les plus petits segments soient créés pour des périodes de l'évènement présentant plus d'entrées de données secondaires associées. De multiples mises en évidence peuvent être réalisées dans un segment particulier, ou chaque segment peut être configuré pour contenir une seule mise en évidence. Au cours de l'évènement, les segments sont stockés, un service de distribution assurant la distribution aux clients, et les données secondaires associées sont stockées dans une base de données ou autre construction.
