Television service providers including cable, satellite, terrestrial, video over Internet, IPTV, and others can deliver a large number of channels to subscribers. To choose and select desired program among hundreds of available channels, subscribers can browse channels one by one or use grid or mosaic based Electronic Programming Guides (EPG) by which they might search for possible choices, with the effect to that those subscribers are able to select one or more choices for presentation. However, while they achieve the general goal of allowing users to search and select, known systems are subject to several draw-backs.
Browsing a large number of channels in a search of a desired show is time consuming and inefficient. For example, to preview currently broadcasted shows subscriber can surf 300 channels one by one while spending 10 seconds on each, requires over 50 minutes, which is, in many cases, longer than subscriber choose to watch television program, or the duration of desired program itself. Grid based EPG, although listing titles of programs for several channels at once, including the option of selecting favorite channels and expediting program selection process, displays on average 2 shows per grid's channel line, for the total of 600 shows subscriber has to view to select desired show. Moreover, grid based EPG does not allow users to observe the actual video content of several channels at once, thus forcing subscribers to decide on channel and program selection merely from its textual description, and not its actual content. Although some EPGs allow subscribers to preview in PIP a program selected from the grid, still users can not simultaneously observe content of more than one program. Grid based EPGs that allow subscribers to search programs by title or content category, displayed search results still in a textual representation of a matched program; at the same time not including in the search programs available over VOD, local or network PVR, or program available thru other service provider or source.
Existing mosaic based EPG (MEPG), used by CANAL+ in France for example, is also limiting since it creates pages made of mosaic element each of which is assigned for an extended period of time to a specific channel. CANAL+ offers 3 screens each with 20 elements for the total of 60 channels. However, for such static MEPG, 300 channels may be presented on 15 separate screens forcing a subscriber whishing to find all “News” programs to preview video content of 300 channels by surfing 15 separate screens each with 20 elements. When a subscriber whishes to compare content of two or more channels not present on the same screen, he or she has to toggle between two or more EPG screens, rendering such system as cumbersome, inconvenient, and difficult to use. Such static MEPG systems do not allow subscribers to customize EPG screens to simultaneously display video content of their favorite channels on the same screen. Also, existing MEPG systems, when attempting to group channels by category (e.g. movies, news, cartoons) fail because the same channel broadcasts shows that can belong to different content categories at different times of the day: “Cartoons” in the morning, “Soap Operas” in the afternoon, “News” in the evening, and “Movies” at night. As the result, with the existing MEPG system, when the channels are grouped by category and displayed on the same screen, subscriber that tunes to “cartoons” mosaic EPG page, expecting to see cartoons, actually sees programs that belong to other content categories.
In U.S. Patent Application No. 20040070593, discloses a mosaic-like UI that can be dynamically rearranged in response, in part, to user selection and static metadata about the video titles stored in the library. However, this solution does not work for the television broadcasting environment where each channel's metadata is not static, but dynamic, since it is being contentiously updated and changed. The '593 application does not take into account business needs of service provider which might want to auction off locations of some or all of the mosaic elements on some or all MEPG screens to broadcasters or other third parties. The '593 application does not allow subscribers to simultaneously view video feed from one of any broadcasting channels on one part of the screen while simultaneously accessing MEPG in the remaining portion of the same screen.
In addition to the difficulties of selecting among a large number of currently broadcasting programs, as described above, subscribers also have many challenges selecting upcoming shows using existing EPGs. Again, to find a show that matches their criteria, subscribers have to review set of hundreds of shows that immediately following currently broadcasting programs plus review another set of hundreds of shows that follow after. This task becomes very arduous because by default programs in the existing grid and mosaic based EPGs are organized by channel and time, but not by program category.
So, to choose desired program subscribers have to review many hundreds of entries most of which do not belong to desired program category. The problem of program selection will be exacerbated in the future when even more channels and programs become accessible to subscribers thanks to proliferation of client PVR, VOD over cable, VOD over Internet, network PVR, and other program delivery methods and service. Not only subscribers would have to review hundreds of available programs many of which are irrelevant to the search since they belong to other program categories, subscribers have to juggle among several EPGs each of which is representing its own service. For example, digital cable service and VOD over cable are represented by their own EPGs, TiVO or ReplayTV PVR services are represented by their own EPGs, and VOD over Internet, like Akimbo, is also represented by its own EPG. With more and more content delivery options, subscribers are forced to spend greater amount of time searching and selecting desired content distributed among various systems represented by own EPGs.
What's more, existing EPG services use textural representation of programs and services, like interactive TV. However, it's been shown that people gravitate towards search of video information not by its textual representation but by its visual representation. The best example of this are display cases of a video store, like Blockbuster. There, latest movie releases are arranged in such a manner as to allow customers to view and select desire program by viewing front covers of the DVD cases. Most DVDs, on their front covers, show a visual representation of the video content that allows them to quickly and easily infer its genre, participating actors, and thus make a selection. Unfortunately, existing EPG services have not been designed to display program's visual representation and allow subscribers to choose desired program by it. Instead, subscribers have to choose desired program by its textual representation.
To simplify content selection process, subscribers ought to have a Content Portal that can allow them to choose desired program based on its visual representation and can consolidate access to programs available over multiple services, including those based on a locally or remotely stored content, and services based on programs broadcasted over various available media. Thus, Content Portal ought to allow subscribers to access currently broadcasted programs, soon to be broadcasted programs, locally stored and remotely stored programs by their visual representation. While consolidating access and selection of programs available over multiple networks, Content Portal should also preserve access to advanced value added services like interactive television and on demand advertisement.
In addition to EPGs, subscribers can choose desired program using other program sources including printed TV guides, and TV guides offered over the Internet. There, subscribers have to deal with the same problems of choosing desired content based on its textual representation, but not on its visual representation.
Similarly to the digital TV service providers, providers of digital and satellite radio services like XM and Cirrus have not incorporated visual representation of broadcasted or soon to be broadcasted content, although amount of available content over hundreds of available channels is large. Similarly to the digital TV service, subscribers to the digital radio service have to choose desired program based on its textual representation. With hundreds of simultaneously available programs, this task becomes as challenging as selecting video content from digital TV service providers.
The invention provides a method and system capable of solving many problems of content preview and selection for visual or audio content offered over digital TV or digital radio networks, and generally a user interface (UI) for accessing content. One aspect of the invention is a method of creating and presenting a Dynamic Mosaic Extended Electronic Programming Guide (DMXEPG) using video, audio, special applications, and service dynamic metadata. The system enables television or digital radio service subscribers to select and display of various programs including video, interactive TV applications, or any combination of audio or visual components grouped and presented in accordance with the dynamic program/show metadata, business rules and objectives of service providers, broadcasters, and/or personal subscriber choices. Another aspect of the invention is to print programming guides or guides in electronic form using the same solution of utilizing dynamic metadata to group, consolidate, and display program information with the purpose of allowing subscribers to view and select desired program using program's visual representation.
In accordance with an aspect of the present invention, the system can merge channel programs/shows metadata for multiple services offered by one or more than one service provider using a unique channel identifier, e.g., a service source ID either for digital TV or radio services. Such merger is performed on the backend and merged metadata is displayed on a client device or in a printed program information guide. This invention differs from the mechanism described in U.S. Pat. No. 6,072,983, which describes merging channel metadata on the client side.
In accordance with an aspect of the present invention, an application can be provided on devices with more than one tuner that can simultaneously display video and applications graphics of that application on more than one display.
In accordance with an aspect of the present invention, applications can be provided on devices with more than one tuner that can simultaneously display a program chosen by the subscriber on one portion of the screen, while displaying DMXEPG or its components on the rest of the screen.
In accordance with an aspect of the present invention, metadata from different value-added services can be integrated into a matrix element (ME) of the DMXEPG and displayed to subscribers for currently broadcasted or soon to be broadcasted programs.
In accordance with an aspect of the present invention, integrated metadata can be recorded for later playback.
Further aspects of the present invention include:

Aspects of a user interface in accordance with the present invention are explained in detail in the illustrative embodiment of the present invention disclosed below relating to electronic program guides for accessing broadcast content. It will be appreciated by one of ordinary skill that any type of content can be accessed using a user interface that incorporates the various elements disclosed hereinbelow.
Returning to
MTVSS filters all programs by program category, subcategory, and genre. The figure depicts filtering by program subcategory “CARTOONS”. As a result of this data processing, system creates record set of all programs during the next 14 days across multiple channels (uniquely identified by source_id) and multiple head-ends (cable, satellite, or other) with the subcategory “CARTOONS”.
MTVSS will process data set made during step 233 and generate Interactive Mosaic channel insertion schedule for all channels that includes “CARTOONS” programs across multiple head-ends. MTVSS will generate schedule for short period (e.g. 1 day), because EPG schedule might dynamically change even inside 14 days windows.
On the local head-end MTVSS will apply (step 235) the local channel lineup, local business rules (e.g. channel priorities, non-video interactive mosaic element components), local conditional access rules (e.g. program rating, blackout), “last-minute” listings update data.
After step 235, MTVSS will generate real-time insertion schedule 236 for CARTOON programs which are broadcasted on this local head-end.
Matrix Remote Monitoring Terminal (MRMT) 242 is a web based interface that allows a system operator to access MTVSS. Once authenticated, the system operator accesses tasks and processes enabled by his security level. The system operator can perform a number of functions including: retrieval of Matrix Meta Data Server status, retrieval of Matrix Scheduler status, retrieval of Matrix SuperSplit status, and retrieval of logs, traces, and statistics for all MTVSS components. Matrix remote management portion of MRMT is a web based interface that allows the system operator to access MTVSS. Depending on granted permissions, the system operator can manage specific tasks and processes. The system operator can perform the following functions: start and stop any process on any MTVSS component, update configuration parameters for any MTVSS component.
Matrix Meta Data Server 243 comprises four components: Data Delivery Manager, Data Translation Manager, Data Cache Manager, and Matrix National resolution EPG database.
Matrix Scheduler (MS) 244 receives and retrieves the following data:
Matrix scheduler comprises five major components: Local Headend Configuration Manager, STB Mosaic GUI Configuration Manager, DMXEPG Application Configuration Manager, Mosaic Meta Data generator, and Matrix Local resolution EPG database importer. Local Headend Configuration Manager is designed to apply local technical (e.g. channel lineup, MPEG2/DCII SI/PSIP tables configuration) and business rules (e.g. channel assignment priority) to the final program mosaic video stream and mosaic meta data. SIB Mosaic GUI Configuration Manager allows a service provider to configure the graphical user interface and provides navigation for the DMXEPG Client application.
Mosaic meta data generator builds Interactive Mosaic descriptor, Interactive Mosaic Master Table, control and scheduling data for the Matrix SuperSplit, and additional mosaic meta data discussed in more detail below. Matrix Local resolution EPG database importer stores EPG listings data in the local database.
Real time or manual EPG listings update terminal 245 is a web based interface that allows system operator to update EPG listings data on local and national head-end before broadcasting.
Matrix Scheduler Configuration terminal 246 is a web based interface that allows system operator to configure program mosaic video stream, DMXEPG Client Application, insert local technical information, insert local business rules, and assign mosaic element components (
Enhanced data and Interactive application Insertion terminal 247 is a web based interface that allows system operator to insert/assign mosaic element components (
The MSS receives:
The MSS composes the final mosaic digital stream which comprises:
DMXEPG-C also can be stored in the available medium such as flash memory, hard drive, or another STB's persistent storage as STB's resident application. There are two scenarios to activate DMXEPG-C, depending on its location.
Interactive Mosaic Private Tables and Descriptor (MPEG 2 Private Section)
The interactive mosaic descriptor can be located in the following MPEG 2/ATSC SI/PSIP/DVB SI tables:
A digital program which carries interactive mosaic can include the interactive mosaic descriptor inside its Program Map section in the program information descriptors loop.
The resource locators' descriptors and Interactive Mosaic Resources Table and Interactive Mosaic Application Table are protocol/transport depended (may be one for DVB SI, one for ATSC PSIP, one for OCAP, one for DSMCC).
The MTVSS implementation in 295 consists of Matrix Scheduler as part of subscriber device. That configuration allows subscriber or third party to control ME mosaic element presentation criteria. The criteria service provider can be any third party that provides mosaic element presentation criteria that is used by the Matrix Scheduler. The criteria service provider can be the manufacturer of the client subscriber device. The criteria service provider can be the subscriber. In the general case, the mosaic element presentation criteria may comprise criteria from any combination of third party providers, the manufacturer, and/or the subscriber.
Mosaic element presentation criteria can be delivered using any suitable delivery medium including an Internet connection, a dial-up service, over the airwaves, satellite link, cable link, and so on. The subscriber can be provided with criteria on a CD that can be installed in the subscriber device.
Numerous combinations of aspect ratios of video sources and aspect ratios of the display area are possible. Typical combinations include:
To virtually increase the size of the video, it is necessary to clip a percentage of the original video feed (which is usually lost because of TV overscan) and scale it to the size and aspect ratio of the target ME. As shown in
To further illustrate this clipping aspect of the present invention,
Other aspect ratios can be accommodated.
Operation
A subscriber, in accordance with the invention, accesses DMXEPG main page which displays content categories grouped by genre, language, broadcaster name, geographical location of the broadcaster, or other pre-set criteria. For example, content can be grouped by genre in “News”, “Movies”, “Sitcoms”, “Cartoons”, “Sports”, and “Favorite” categories
If subscriber wants to observe more choices in a particular content category, he can press “ENTER” button on the remote control or depress optional rotating element 301 which brings subscriber to another DMXEPG page
With the set-top box with 2 or more tuners, in accordance with the invention, subscriber, after accessing mosaic DMXEPG landing page, selecting content category, and viewing corresponding DMXEPG page is given the option of selecting any video stream, including video from other sources like DVD player, on one ME while observing DMXEPG elements on the rest of the screen
With the set-top box with 2 or more tuners, in accordance with the invention, subscriber, after accessing DMXEPG screen, can optionally select size of ME in focus by pressing “ENTER” or any other button assigned to that function. In case of subscriber device capable of three dimensional rendering, subscriber can also choose Z coordinate of ME.
Service Provider, in accordance with the invention, can dynamically change rules responsible for dynamic association of channels with the mosaic DMXEPG elements. For the main landing page, service providers can choose to change displayed content categories, advertisement, or other visual or audio data depending on the time of the day, day of the week, customer demographic data, capabilities of customer premises equipment, and capabilities of the head-end equipment, as well as its business needs.
