The present invention generally relates to display control and programming and, more particularly, to a method, apparatus and system for providing improved transitions between alternating individual channel programming and common channel programming using synchronized playlists.
Information and content distribution systems are used to provide information and content to a plurality of end systems. Such systems are constantly evolving and the demand for improved performance is continually on the rise. 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. On occasion, in such video-on-demand systems, a single channel is communicated to all subscriber set-top boxes.
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 receiver, such as a set-top-box for each display or group of displays and a speaker for audio systems, typically in the form of playlists. Retailers use the displays and audio systems to present their current offerings or sale information in the form of respective playlists for each of the channels or groups of channels, 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.
In various content distribution systems as those described above, the playlists include programming for a single channel (e.g., a headline channel) to be communicated to all receivers at determined time periods for the purposes of communicating a synchronized message across all available channels. In such systems, switching receivers or displays at the correct time to a single common channel (e.g., a headline channel) provides a powerful tool for distribution and a powerful messaging medium for advertising. That is the advertising message is more effectively communicated with a synchronized approach where receivers, such as screens and speakers in an advertising environment, such as a store, can alternately show headline programming (in sync with all other screens and speakers) and department or local channel level programming. At appropriate points in the playlists, the receivers or displays must be able to alternate between headline programming and individual department/local channel programming. However, traditional store-wide and department TV channels are not as effective as desired. There are drawbacks to the currently available models for switching receivers to a single common channel. More specifically, in such applications, the effectiveness of the switch is diminished if the switching occurs at the wrong time, for example, in the middle of an advertisement. More specifically, if multiple channels are involved then the end point will not be at one point in time for all channels. This would result in one or more channels being cut off at the switching point. That is, current channel switching approaches are unable to support seamless transitions between alternating department/local channel and headline programming.
Embodiments of the present invention address the deficiencies of the prior art by providing a method; apparatus and system for providing improved transitions between alternating individual channel programming and common channel programming using synchronized playlists.
In various embodiments of the present invention, applications are provided that provide a synchronized playlist calculation, which are used to calculate playlists and filler media for seamless transitions during the alternation of individual and common channel programming.
In one embodiment of the present invention, the optimum switching (synchronization) point is determined. Subsequently, channels not having a termination/end point consistent with the determined switching point are padded with respective filler content (media) to coordinate the termination points of the channels to be synchronized. The amount of filler content needed for each channel is determined respectively for a channel.

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 in one embodiment of the present invention, 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.
In various embodiments of the present invention, the various streams can be organized in the form of playlists to be communicated to the various receivers throughout the store and displayed on specific displays in a predetermined order and frequency. That is, embodiments of the present invention provide a method, apparatus and system including a calculation of synchronized playlists [Synchronized Playlists Calculation (SPC)] and determination of filler media needed for seamless transitions during the alternation of local and headline programming across a plurality of content channels. It should be noted that the terms local and individual channel are to be considered interchangeable throughout the teachings of this disclosure.
The synchronization of the present invention can be determined or calculated at a remote server, such as the NMC 210 or the NOC 220, or at a local server such as the server 110 of the content distribution system 100 of
In accordance with an embodiment of the present invention, initially a synchronization point is determined. A synchronization point is a point in time which marks a transition between local and headline programming. In one embodiment, two types of Synchronization points are defined; an Ideal Synchronization point and a Real Synchronization point. An Ideal Synchronization Point is the ideal point in time at which a transition between department and headline programming should take place and vice versa. For example, headline programming should play for exactly an amount of time equal to the headline duration, at which point the programming should transition into local programming.
A Real Synchronization Point is the real point in time at which a transition between department and headline programming takes place and vice versa. Due to the fact that media files are of arbitrary length, the SPC must calculate a Real Synchronization Point as close to the Ideal Synchronization Point as possible, depending on the arbitrary lengths of the media files. For making this determination, the duration of the various programming channels must be taken into account.
For example, a Headline duration defines a length of time that the headline channel will play before a transition to department programming. A local channel duration defines a length of time that respective local channels will play, before a transition to headline programming. Filler media is a media which is used to pad a programming channel (View) until the length of the View approaches the Real Synchronization Point.
As previously described, a goal of an SPC of an embodiment of the present invention is to calculate and select a Real Synchronization Point which is closest in time proximity to the Ideal Synchronization Point, regardless if the calculated value falls before or after the Ideal Synchronization Point. For purposes of the calculation and in one embodiment of the present invention, the inventors consider a playlist for a particular channel a sequential loop. In addition, when building a View for a particular channel, the next media to be added to a View is considered the last recently added media file in the playlist. Even further, the inventors consider that the View length across all department channels for a given time period must be the same because all department channels are synchronized to transition to the headline channel at the same time.
As such, to determine a Real Synchronization Point for the transition of the headline channel into respective local channels, method 300 of
At step 304, a Sum Before is determined. More specifically, for the headline duration period, a total number of headline media files (sequentially added from a headline playlist) that can fit within the headline duration period, without exceeding the time of the headline duration, are compiled. The method 300 then proceeds to step 306.
At step 306, a Sum After is determined. More specifically, a total number of headline media files (sequentially added from a headline playlist) that can fit within the headline duration period, until the first instance that the headline duration period is exceeded by a media file, are compiled. The method 300 then proceeds to step 308.
At step 308, a Real Synchronization Point is determined. That is, the Real Synchronization point is chosen by selecting either the Sum Before list of headline media files or the Sum After list of headline media files depending on which list of media files falls closest to the Ideal Synchronization Point. If the time deltas are equal, then in one embodiment of the present invention, the Sum Before is chosen. As such, the Real Synchronization Point is considered the end point in time or the synchronization point for system programming to transition from the headline channel back into respective local channels.
Similarly, to determine a Real Synchronization Point for the transition from respective local channels to a headline channel, method 400 of
At step 404, an Ideal Synchronization Point is determined or considered. That is, in one embodiment of the present invention at step 404 the start time of the next Headline event is considered as the Ideal Synchronization Point. The method 400 then proceeds to step 406.
At step 406, a Sum Before is determined for each local channel. More specifically, for each local channel a total number of media files (sequentially added from a local channel playlist) that can fit without exceeding the Ideal Synchronization Point are compiled. That is, the view for each channel is initially created with as many channel respective media files as possible, without exceeding the time until the Ideal Synchronization Point. As such, a Real Synchronization Point is determined for each channel. The method 400 then proceeds to step 408.
At step 408, the respective local channels are synchronized by adding a respective amount of filler media to each of the local channels to extend the media content of each of the local channels from the position of the respective Real Synchronization Points for each channel to the Ideal Synchronization Point. That is, at step 408, the views of each channel are extended to the Ideal Synchronization Point in order to synchronize the channels.
In accordance with the present invention, filler material can include video content in the form of advertisements, store announcement, and the like. In addition, filler material can be provided in substantially any length for extending channel content to synchronize channel views.
At step 504, the predetermined local channel duration period is considered as the Ideal Synchronization Point. The method 500 then proceeds to step 506.
At step 506, a Sum Before is determined for each local channel. More specifically, for each local channel a total number of media files (sequentially added from a local channel playlist) that can fit without exceeding the Ideal Synchronization Point are compiled. That is, the view for each channel is initially created with as many channel respective media files as possible, without exceeding the time until the Ideal Synchronization Point. As such, a Real Synchronization Point is determined for each channel. The method 500 then proceeds to step 508.
At step 508, the respective local channels are synchronized by adding a respective amount of filler media to each of the local channels to extend the media content end point of each of the local channels from the position of the respective Real Synchronization Points for each local channel to the Ideal Synchronization Point. That is, at step 508, the views of each channel are extended to the Ideal Synchronization Point in order to synchronize the local channels.
In an alternate embodiment of the present invention, the method 500 can be modified to consider the local channel having a Real Synchronization point closest to the Ideal Synchronization point as the new Synchronization point. For example,
At step 604, the predetermined local channel duration period is considered as the Ideal Synchronization Point. The method 600 then proceeds to step 506.
At step 606, a Sum Before is determined for each local channel. More specifically, for each local channel a total number of media files (sequentially added from a local channel playlist) that can fit without exceeding the Ideal Synchronization Point are compiled. That is, the view for each channel is initially created with as many channel respective media files as possible, without exceeding the time until the Ideal Synchronization Point. As such, a Real Synchronization Point is determined for each channel. The method 600 then proceeds to step 610 (or optionally to step 607).
At optional step 607, a Sum After is determined for each local channel. More specifically, for each local channel a total number of media files (sequentially added from a local channel playlist) that can fit within the local channel duration period, until the first instance that the local channel duration period is exceeded by a media file, are compiled. The method 600 then proceeds to optional step 608.
At optional step 608, the local channel having Sum Before or Sum After end point closest to the predetermined Ideal Synchronization Point is considered the new Synchronization Point. The method 600 of then proceeds to step 612.
At step 610, the local channel having the Sum Before end point closest to the predetermined Ideal Synchronization Point is considered the new Synchronization Point. The method 600 then proceeds to step 610.
At step 612, the respective local channels are synchronized to the new Synchronization Point by adding a respective amount of filler media to each of the local channels, except the local channel chosen as the new Synchronization Point, to extend the media content of each of the local channels from the position of the respective Real Synchronization Points for each channel to the new Synchronization Point. That is, at step 608, the views of each channel are extended to the new Synchronization Point in order to synchronize the local channels to the local channel chosen as the new Synchronization Point. In this alternate embodiment of the present invention, it is guaranteed that at least one local channel will not require filler media.
