Patent Application
20100162330
The present invention generally relates to playlist-based audio/video systems and, more particularly, to a method, apparatus and system for the control and over-ride of playlists.
Information and content distribution systems are used to provide information and content to a plurality of end systems. For example, in video-on-demand applications media content has been made available to and utilized by satellite/cable television subscribers. Typically, subscribers can view at their television via a set-top box the video programs available for selection (sometimes for an additional fee) and upon selection made at the subscriber's set-top-box (STB), the program is sent from the program center to the set-top-box via the cable or satellite network. Playlists can be implemented in video-on-demand applications to schedule video programming and advertisements.
Similarly, in the advertising realm, providing in-store retail media content is becoming the most popular advertising medium in use today, with broadcast distribution being its primary means of content presentation. That is, in recent years retailers and the managers of public spaces have brought in video display systems for advertising use. In such systems, content is distributed by a server and received at a respective set-top-box for each display or group of displays. Retailers use the displays to present their current offerings or sale information, while the public spaces sell time on the video displays to advertisers either national or local, knowing that large numbers of consumers will see the presentation. Again, in such in-store retail advertising systems, playlists can be implemented to schedule media clips of current offerings, sale information or advertisements.
In such systems, many situations can arise that require dynamic changes to the playlist to meet business objectives—such as substituting a specific media file or set of media files for others; not playing a specific media file or set of media files; inserting a specific media file or set of media files. Building a new playlist at a centralized network operations center may not be a viable solution in these cases. Possible reasons can include the desire for the changes to happen as rapidly as possible (thus bypassing the time required to process through the central system) or the desire to allow a local entity to have control over the playlists without having to coordinate with the central system.
Embodiments of the present invention address the deficiencies of the prior art by providing a method, apparatus and system for the control and override of the playout of playlists.
The various embodiments of the present invention include a means of providing only the changes to be made to a playlist and remove the need to provide a totally new playlist. In one embodiment of the present invention, a media playback system would dynamically apply change instructions in real-time to existing playlists rather than building new playlists.
In one embodiment of the present invention a method for providing a dynamic override of at least a portion of a playlist includes identifying a location in the playlist that requires change and changing a media portion presented during the intended presentation time of the identified location in the playlist without modifying the playlist.
In an alternate embodiment of the present invention, a playout system for providing a dynamic override of at least a portion of a playlist includes at least one programming control system for providing at least playlist override instructions and at least one playout apparatus for executing the playlist override instructions where the playout apparatus is adapted to perform the steps of identifying a location in the playlist that requires change and changing a media portion presented during the intended presentation time of the identified location in the playlist without modifying the playlist.
The teachings of the present invention can be readily understood by considering the following detailed description in conjunction with the accompanying drawings, in which:
It should be understood that the drawings are for purposes of illustrating the concepts of the invention and are not necessarily the only possible configuration for illustrating the invention. To facilitate understanding, identical reference numerals have been used, where possible, to designate identical elements that are common to the figures.
The present invention advantageously provides a method, apparatus and system for the control and over-ride of local playlists for causing changes to the presentation of an existing playlist.

In one embodiment of the present invention, the content distribution system 100 of
In one embodiment of the present invention, software for controlling the various elements of the in-store advertising network 200 and the content distribution system 100 can include a 32-bit operating system using a windowing environment (e.g., MS-Windows™ or X-Windows operating system) and high-performance computing hardware. The advertising network 200 can utilize a distributed architecture and provides centralized content management and distribution control via, in one embodiment, satellite (or other method, e.g., a wide-area network (WAN), the Internet, a series of microwave links, or a similar mechanism) and in-store modules.
As depicted in
A recording company 204 can be a record label, music publisher, licensing/publishing entity (e.g., BMI or ASCAP), individual artist, or other such source of music-related content. The recording company 204 provides audiovisual content such as music clips (short segments of recorded music), music video clips, and the like. The movie studio 206 can be a movie studio, a film production company, a publicist, or other source related to the film industry. The movie studio 106 can provide movie clips, pre-recorded interviews with actors and actresses, movie reviews, “behind-the-scenes” presentations, and similar content.
The other content provider 208 can be any other provider of video, audio or audiovisual content that can be distributed and displayed via, for example, the content distribution system 100 of
In one embodiment of the present invention, content is procured via the network management center 210 (NMC) using, for example, traditional recorded media (tapes, CD's, videos, and the like). Content provided to the NMC 210 is compiled into a form suitable for distribution to, for example, the local distribution system 100, which distributes and displays the content at a local site.
The NMC 210 can digitize the received content and provide it to a Network Operations Center (NOC) 220 in the form of digitized data files 222. It will be noted that data files 222, although referred to in terms of digitized content, can also be streaming audio, streaming video, or other such information. The content compiled and received by the NMC 210 can include commercials, bumpers, graphics, audio and the like. All files are preferably named so that they are uniquely identifiable. More specifically, the NMC 210 creates distribution packs that are targeted to specific sites, such as store locations, and delivered to one or more stores on a scheduled or on-demand basis. The distribution packs, if used, contain content that is intended to either replace or enhance existing content already present on-site (unless the site's system is being initialized for the first time, in which case the packages delivered will form the basis of the site's initial content). Alternatively, the files may be compressed and transferred separately, or a streaming compression program of some type employed.
The NOC 220 communicates digitized data files 222 to, in this example, the content distribution system 100 at a commercial sales outlet 230 via a communications network 225. The communications network 225 can be implemented in any one of several technologies. For example, in one embodiment of the present invention, a satellite link can be used to distribute digitized data files 222 to the content distribution system 100 of the commercial sales outlet 230. This enables content to easily be distributed by broadcasting (or multicasting) the content to various locations. Alternatively, the Internet can be used to both distribute audiovisual content to and allow feedback from commercial sales outlet 230. Other ways of implementing communications network 225, such as using leased lines, a microwave network, or other such mechanisms can also be used in accordance with alternate embodiments of the present invention.
The server 110 of the content distribution system 100 is capable of receiving content (e.g., distribution packs) and, accordingly, distribute them in-store to the various receivers such as the set-top boxes 120 and displays 130 and the speaker systems 135. That is, at the content distribution system 100, content is received and configured for streaming. The streaming can be performed by one or more servers configured to act together or in concert. The streaming content can include content configured for various different locations or products throughout the sales outlet 230 (e.g., store). For example, respective set-top boxes 120 and displays 130 and various speaker systems 135 can be located at specific locations throughout the sales outlet 230 and respectively configured to display content and broadcast audio pertaining to products located within a predetermined distance from the location of each respective set-top box and display.
The server 110 of the content distribution system 100 receives content and creates various different streams (e.g., content channels) of audio, video and/or audio/video to be communicated to the various receivers throughout the store. The streams can be individual channels of modulated audio, video and/or audio/video onto a radio frequency distribution or transmitted as data flows within a unicast or multicast internet protocol (IP) network. These streams can originate from one or more servers under the same logical set of control software.
The various embodiments of the present invention provide a means to codify a set of changes to a playlist or a set of playlists. These changes can be applied according to instructions with defined conditions included in playlist override information provided to a playout system/apparatus. In one embodiment of the present invention, the playout system/apparatus can comprise the server 110 of the content distribution system 100. In alternate embodiments of the present invention, however, the playout system/apparatus can comprise a separate unit or device, which will be described in more detail below.
These defined conditions can include applying the changes for specific periods of time (or patterns of time, such as every day from 2 pm to 4 pm), specific playout locations (such as specific stores or channels), or specific presentation locations (such as display or speaker locations). For example, some advertising media can be determined to be more suitable for certain times of the day, for example because of adult content in advertising material, or can be determined to be more suitable for certain locations, for example because of demographics (e.g., content in different languages or directed to different age groups), or can be determined to be more suitable for locations in a store because of product in the proximity of the display or speaker locations. As such, in accordance with the various embodiments of the present invention, media portions can be inserted, deleted, overridden and/or replaced (described below) to accommodate for such factors without having to modify existing playlists.
The playlist override information of the present invention can include conditional rules where the override instructions would not be processed unless other conditions associated with the media, the playout system or the location of the playout system were met, such as digital rights management processing, service level agreement with an advertiser or media provider, playout system status, impressions, and product movement related to the media including sales transactions and inventory to name a few.
In various embodiments of the present invention, the playlist override information can include instructions that can be of three basic types: insert, replace, and delete. Inserts would add a new clip or playlist at a specified point in the playlist being over-ridden. Note that the playlist would not change, only the interpretation of the playlist by the playout system/apparatus at run-time would change. Likewise, delete instructions would result in the specified clip or clips not playing in the realized run-time playback. Replace operations would result in a different specific media clips being played in place of specific other clips in the playlist.
In one embodiment of the present invention, the playlist override information and instructions can be generated in response to conditions associated with the programming or media change after the playlist or playlists have been created and distributed. These conditions can include problems or concerns with the media referenced in the existing playlist at a playout system, problems fulfilling the advertiser's or media provider's service agreement, an advertiser's or other media provider's campaign changes associated with changes in consumer behavior, impressions, product or service availability, the venue owner where the playout system is located, such as a retailer or building owner, has promotional or communication needs that change, or the consumer makes requests of the system to add or remove content based on their needs. In accordance with various embodiments of the present invention, the changes can be made from a central programming control system, for example at the network management center 210 or the network operations center 220, or several programming control systems (e.g., interfaces) driven by, for example, local users, a network operator, an advertiser, a media provider, a venue owner (such as retailer), and a consumer with access to the playout system. The venue owner can empower central personnel or local personnel to make the changes based on local needs versus the needs of multiple playout system locations or a centralized network.
In one embodiment of the present invention, a playout system receives override information for a specific and identified playlist from at least one of a network management center, a network operations center or from a local server in, for example, a retail advertising environment. The override information can include identification information identifying a specific one or specific ones of playlist(s) that require a change. The override information can further include media clips or portions intended to replace specific media portions in the playlist to be changed or can include media portions to be added to a playlist. The override information can further include information as to a portion or portions of an identified playlist or playlists to be deleted and as such not presented by a receiver (e.g., display or speaker).
In one embodiment of the present invention, in order to track and understand changes occurring for the proper recognition of playout results, the playout system can generate a new playlist with the override instructions executed showing the changes that will be taken under the current conditions occur. The conditions would be recorded in the new playlist as well as the changes to the media, sequencing and layout. This new playlist can be returned to the programming control system, which could then use it as the definition of expected execution at the playout site. When the playout system records and transmits back to the programming control system the actual executed results, it will be able to correlate the expected with the actual based on the new playlist as well as integrate with the conditions that caused the playlist changes or additional conditions, such as consumer behavior changes or lack of changes, product or service availability, impressions, and create either new playlists or new playlist override instructions. In addition, the expected and actual playout status could be used to establish a proof of performance to the advertiser, media provider, or venue owner.
At step 304, a location or locations in a playlist or playlists that require changes are identified using the received playlist override information. The method 300 then proceeds to step 306.
At step 306, the changes are executed at the respective presentation (i.e., display for video and presentation for audio) times of the identified locations within the playlist(s). More specifically, at step 306, if an identified portion of a playlist requires changes (e.g., replacment, insertion, deletion, of a media portion), a playout apparatus/system executes the changes identified in the playlist override information by causing the presentation at a receiver of an alternate media portion in place of an identified media portion of the playlist requiring replacement, and/or by causing an identified media portion of the playlist requiring deletion not to be performed and/or by causing the performance of a media portion identified as needing to be added to the playlist at the point in time of an identified location in the playlist. The method 300 is then exited.
In accordance with the embodiments of the invention described above, the playlist override playout is performed without having to make any modifications to the playlist, itself. Instead, a playout system/apparatus, in response to a received request for modification of a playlist and in accordance with received playlist override information, causes changes in a playout of a playlist at an end receiver (e.g., a display or a speaker) by either causing the playout of alternate video and/or audio content over identified media content of the playlist at an end receiver, or by causing a portion of the media content in the playlist identified by the playlist override information to be deleted not to be played out by the end receivers, or by adding media content to a playlist by causing end receivers to receive the additional media content during an identified time. In one embodiment of the present invention, the addition content and replacement content is provided to a playout system/apparatus along with the playlist override information. In alternate embodiments of the present invention, a playout system/apparatus of the present invention can have storage means (such as a memory, or hard disk, etc.) for storing media content to be used for the playlist override concepts of the present invention.

Referring back to
Upon receiving the playlist override information and the media content, the playout apparatus 424 identifies areas in the media content that require changes or updates by using the playlist override information. The playout apparatus 424 then executes the required changes before communicating the media content to a end receiver (e.g., display or speaker) for display or presentation. More specifically, the playlist override information received by the playout apparatus 424 can identify specific portions of the media content that require deletion, or that need to be overwritten or areas in the media content that require additional media added. The playout apparatus 424 then causes the presentation of the corrected or updated media content by, in the case of replacement media connate and additional media content, causing the alternate or additional data to be communicated to a respective end receiver for presentation in place of the original media content. For the case of the deletion of media content, the playout apparatus 424 causes the media content to be deleted to not be communicated to a respective end receiver.
As depicted in
As previously described, in one embodiment of the present invention, additional or alternate media content for fulfilling the requirements of the playlist override information can be communicated to the playout apparatus 424, for example along with the media content or the playlist override information or at a separate time. In alternate embodiments of the present invention, additional or alternate media content for fulfilling the requirements of the playlist override information can be stored in a memory or storage means of the playout apparatus 424.
It should be noted that the use of the term “display” throughout the teachings of this disclosure should not be considered as being limited to the presentation of video, but can be representative of either the presentation of video on, for example, a display or the presentation of audio on, for example, a speaker and/or both on an integrated device. In addition, it should be noted that the term “media content” and/or “media portion” and/or “media clip” used throughout the teachings of this disclosure can be used to identify media content including video portions, audio portions and/or both.
Having described various embodiments for a method, apparatus and system for the control and over-ride of the presentation of playlists (which are intended to be illustrative and not limiting), it is noted that modifications and variations can be made by persons skilled in the art in light of the above teachings. It is therefore to be understood that changes may be made in the particular embodiments of the invention disclosed which are within the scope and spirit of the invention. While the forgoing is directed to various embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof.
