In
Television apparatus 100 is adapted to receive a broadcast signal 110 (broadcast television signal) transmitted by a broadcast station 112. Broadcast signal 110 may be an analog or a digital television broadcast signal, e.g. in accordance with a DVB, ATSC, ISDB or DMB standard. Accordingly, transmission of the broadcast signal may be realized by terrestrial transmission (DVB-T, DVB-T2, DVB-H, DVB-SH, ATSC, ATSC-M/H, ISDB-T, or T-DMB), by cable transmission (DVB-C, ATSC, ISDB-C), by microwave transmission (DVB-MT, DVB-MC, or DVB-MS), by satellite transmission (DVB-S, DVB-S2, DVB-SH, DVB-SMATV, ISDB-S, or S-DMB) and/or by internet transmission (DVB-IPTV, DVB-IPI).
In case broadcast signal 110 is a digital television signal, service information (SI) may be transmitted within broadcast signal 110, such as DVB-SI according to the DVB standard. The service information may include various data, such as network information, channel information, program information, time and date information and/or running status information descriptive of programs that are currently aired or that will start in the near future.
Broadcast signal 110 may be received at television apparatus 100 e.g. by an antenna 114 transmitting broadcast signal 110 to a tuner 116. Tuner 116 may tune to channels and/or services transmitted by broadcast signal 110, thereby decoding the channels. Further, a data processor 118 may be provided for displaying the channel at a display 120, e.g. the currently aired program or event.
“Channel” should be understood as that which is conventionally understood by a user, e.g. BBC1, ZDF, TF1 or Fox News, which is termed a service in the DVB environment. Program or Event should be understood as broadcast of finite duration on a channel, such as Desperate Housewives, Tuesday 24 March, 18.45 to 19:00 and a channel name or number.
For allowing a user to interact with television apparatus 100, various input devices may be provided, such as, for example, a remote control 122 and a keypad 124.
Further, television apparatus 100 may include a storage 126 for storing software and data.
The software stored in storage 126 may include, for example, an operating system for operating television apparatus 100, and application software to be run e.g. on demand by a user. The application software may, for example, include an application for providing an electronic program guide. Further, the software may include an application execution engine, providing a runtime environment for executing further applications and/or executable code components, such as widgets, gadgets, applets or the like. The further application may, for example, be interpreted by an alternative software stack running on television apparatus 100, e.g. a software stack configured to interpret XML or RSS feeds (as Rich Site Summary, RDF Site Summary, and/or Really Simple Syndication), by which the further applications may be defined.
The data stored in storage 126 may include content, such as multimedia data, e.g. video data recorded from the broadcast signal, and further multimedia data, such as images, audio/video data (in files or streams), textual data and/or executable applications, such as video games. Further, meta data related to content available for display, and/or a data for running the electronic program guide may also be stored in storage 126. Still further, data related to applications that may be run within the application engine may also be stored, such as data defining an application logic and information to be made available to the user when the application is run.
For communicating over network 108, e.g. with application information server 102 and first and second application servers 104, 106, a communication unit 128 may be provided at television apparatus 100. This may be integrated in the television apparatus or may be a set top box or side box connectable to the television apparatus.
Accordingly, also at application information server 102 a communication unit 130 connected to a data processor 132 may be provided. Data processor 132 may further have access to a storage 134 and to a reading unit 136.
Reading unit 136 may be adapted to read a data storage medium 138, which may, for example, include program instructions. The program instructions, when loaded into data processor 132, may be adapted to cause application information server 102 to perform a method for retrieval of executable applications in accordance with one of the embodiments described herein. The computer program instructions may further be adapted to cause transmission of applications and data over network 108 to television apparatus 100, the applications causing television apparatus 100 to contribute to the method.
At television apparatus 100, retrieval of executable applications may take place while a channel is being decoded, e.g. being viewed by a user. Decoding the channel may be achieved by tuning tuner 160 to the channel transmitted with broadcast signal 110, e.g. for displaying the channel at display 120 to be viewed by the user.
Via network 108, television apparatus 100 may have access to a multitude of content and applications. However, it may be of interest for broadcasters and content owners of the broadcast data to control the access to content and applications which may be displayed on connection with the broadcast data. For example, the broadcasters and content owners may want to have an influence and/or to maintain control of what content and applications are made available to the user when watching their channels. Further, there may exist regulations or business rules defining what can and cannot be done in terms of displaying applications and content together with the broadcast signal. This may ensure that the content owner's rights are not infringed when their content is on air. An example of this is the restriction of “overlaying” applications or content over the broadcaster's content.
For influencing and/or maintaining control of what content and applications are made available to the user when watching the channel, there may exist a definition of what content and applications may be available, e.g. be allowable or even suggested/recommended to be used in connection with the channel. Allowable and/or recommended content and applications may for example be defined by broadcasters, content owners, internet service providers, a manufacturer of television apparatus 100 or a provider of application information server 102.
For example, a broadcaster may want to suggest an application that enables the user to participate at e.g. a voting procedure related to a game show displayed at his channel, so that the voting procedure is to be made available or is recommended. An application available for execution is therefore to be understood as an application which is obtainable, i.e. accessible for execution in conjunction with the decoding of the channel. The application may, for example, be recommended or suggested for being executed in conjunction with the decoding of the channel. For example, access to the application may be given by the application information.
Further, the broadcaster may want to exclude a competitor's advertisings from being displayed in connection with one of his channels, the competitor's advertizing consequently being not allowed for display in connection with the channel. An application allowable for execution whilst a channel is decoded is therefore to be understood as an application to which a consent for execution in conjunction with the decoding of the channel is given, e.g. by the broadcaster. The consent may be defined by a rule, e.g. a business rule.
The definitions of the available, allowable and/or recommended content may be implemented, e.g. in a rule set, at application information server 102, as will be described in detail below.
Channel information may therefore be requested as a basis for retrieving executable applications, executable code components and/or content available, allowable and/or recommended for execution in connection with the channel at television apparatus 100. Consequently, data processor 118 and/or communication unit 128 may analyze the channel currently decoded, and may generate channel information descriptive of the channel.
To determine the channel information, data processor 118 or communication unit 128 may refer, for example, to service information included in a data stream transmitted by broadcast signal 110. In the service information, the available channels or services may be uniquely identified by a channel identifier, e.g. by a number commonly referred to as “triplet” or triplet information. Triplet information, as used in digital television broadcasting, includes three parts: a first part, also referred to as original network ID (OID), a second part, also referred to as transport stream ID (TSID), and a third part, also referred to as service ID (SID), identifying the channel and/or service. In the case of DVB, the triplet may be written as DVB://OID.TSID.SID. According to the DVB standard, the triplet may be used by television tuners to map a channel to the specific broadcast frequency. In the example, the triplet may be used for determining the channel information. Alternatively, also the channel name or a channel identifier, included e.g. in broadcast signal 110, may be used for generating channel information.
The channel information may then be transmitted by communication unit 128, providing an interface for bidirectional communication with network 108, to application information server 102, which receives the channel information via communication unit 130.
Reception of the channel information by application information server 102 may be interpreted as a request for receiving applications that can be accessed (i.e. are available and/or allowable) and executed at television apparatus 100 and that are admitted and/or suggested for use while the channel is received. In the example depicted in
The request may be passed from the communication unit 130 to data processor 132, which may, as a consequence, determine application information based on the channel information. For example, data processor 132 may analyze the channel information and may generate application information descriptive of a set of applications which are available (recommended) and/or allowable for execution whilst channel X is displayed. The application information may be provided, as illustrated in the example by second arrow 142, as a first list of applications.
The first list of applications may refer to applications to be executed at television apparatus 100 in a stand-alone mode or within a framework, such as the application execution engine mentioned above. The applications may be resident applications which may be stored permanently at television apparatus 100, or temporal applications that may be deleted after having been run, e.g. when a channel switch occurs or when television apparatus 100 is switched off. The applications may provide access to data accessible over network 108, as for example in case of a calendar or clock widget, or of a whether widget providing a whether forecast for a given location, e.g. the location of television apparatus 100. Further, the applications may establish an interactive communication with a further remotely located server, as for example an application for selecting and downloading recipes presented in a cooking show. Still further, the applications may allow transmitting data to a still further remotely located server, as for example a voting widget, allowing voting for candidates of a game show or the like.
The first list of applications may be transmitted via communication unit 130 over network 108 to television apparatus 100, which may receive the first application list via communication unit 128. The first application list may then be displayed by data processor 118 at display 120. For displaying the first application list in connection with the channel being displayed, the video image may be shrunk, e.g. displayed only on a part of display 120, thereby leaving a space to display the first application list. Alternatively, the list may also be displayed in a transparent manner overlapping a video image currently displayed at the channel.
In the example depicted, the first application list includes applications 1, 2, and 3, and further related information. For example, information of how to access the respective applications may be indicated by unique resource identifiers URI1, URI2 and URI3. The unique resource identifiers may identify locations on a local server, or on a remote host if the applications are provided by a third party. The URIs may therefore indicate where to locate the application resources, such as code, images and/or further content. Further, for each of the applications, additional information, such as descriptions 1, 2, and 3 may be provided, e.g. for supporting the user when selecting an application to be accessed.
By use of an input means, e.g. remote control 122 or keypad 124 or, alternatively, by speech commands, the user may select one or several of the applications for download and/or execution. In the example depicted in
In the example, the third application may not yet be available locally at television apparatus 100. Therefore, as illustrated in Fig. lb with third arrow 144, the third application, e.g. executable code components of the third application, may be downloaded over network 108. The location for retrieving the third application may be identified by resource identifier URI3, identifying first application server 104, at which the third application with its application logic and application data may be stored.
After download, the executable code components of the third application may be executed at data processor 118 and may be displayed in connection with channel X. In the example, the third application implements a voting procedure allowing the user to vote e.g. for candidates in the game show displayed at channel X. The application thereby allows interacting with first application server 104 over network 108. This enables the user to actively contribute to a TV show he is watching.
As illustrated in
Upon the channel switch to the further channel Y, execution of a certain application (e.g. the third application), which had been executed in conjunction with channel X, may be stopped, since the certain application may not be available, allowable or recommended for execution whilst the further channel Y is decoded.
Upon this request, application information server 102 publishes a second application list, as indicated with seventh arrow 150. The second application list may include further applications, such as applications 4, 5, and 6, which are available and/or allowable, e.g. suggested for execution while channel Y is displayed.
As illustrated in the example, the user may select application 5 highlighted at display 120. As indicated in the second application list, application 5 is supposed to be located at second application server 106 identified by URI5. Upon selection, application 5 may be downloaded from second application server 106, as indicated by an eighth arrow 152.
The embodiment illustrated in
In the example, a request 204 including the channel information and further information as a basis for determining the application information is sent from television apparatus 200 to application information server 202.
In request 204, the channel information may be encoded as a triplet 111.222.333 descriptive of the channel currently displayed at television apparatus 200. Further in request 204, BBC™ may be identified as a provider of the channel.
Additionally, a model or type of television apparatus 200 may identified in request 204, e.g. by a device identifier, in the example “XFV-100”. The device identifier may further encode a device profile descriptive of a hardware configuration of television apparatus. The device profile may be determined by reading hardware specification data from a memory in the device or a connected device, identifying and transmitting details of a firmware version of a device, actively scanning data storage devices to determine available storage capacity or polling or pinging network connected devices to determine network capacity.
Further, a subscriber number 4711 identifying e.g. a registered user having subscribed to the service of retrieving application information may be included. Thus, the service of retrieving applications may be coupled to obligations of payment, e.g. for the service of retrieving the application information, or as a basis for billing for the download of applications against payment. The subscriber number may further give access to a user profile stored at application information server 202.
Still further, the user profile may be transmitted with or updated by request 204, as indicated with a user profile number 0051.
Additionally, a location of television apparatus 200 may be encoded in request 204. For determining the location at television apparatus 200, various possibilities exist. For example, the location may be entered directly by the user, e.g. indicating a postal code or zip code of his home. Further, the location may also be determined by a network address, such as an IP address or the like. Still further, the location may also be determined by analyzing the broadcast signal received at television apparatus 200, e.g. by analyzing the available channels, the mapping of the channels to transport streams, or by analyzing the triplet information. Alternatively, the location of television apparatus 200 may also be determined at application information server 202, e.g. by analyzing the information received with the request, such as the subscriber number.
As further information, the local time at the location of television apparatus 200 may also be transmitted with request 204. For example, devices of a population of television apparatuses requesting the application information could reside in different time zones. In such a case, some logic could be implemented at the server side for determining the local time of a requesting device. If transmitted with the request, the local time from the device could be used to cross check for accuracy. Further, the local time transmitted could be used for simplifying the determination of the local time. Knowledge of the local time of the requesting device may be helpful for determining applications having a time based rule-set, implementing rules like for example “Don't make the big brother voting widget available until 8 PM on Friday, deactivate the widget at 8:30 PM”.
When received by application information server 202, request 204 may be passed to a requester 206 implementing a listener process for capturing the information published from television apparatus 200. Further, the listener process may also be adapted to collect corresponding requests for application information, e.g. from a population of client television devices. Requester 206 may preprocess request 204, e.g. by decoding and/or completing the included information, and pass the respective data to a processor 208.
Processor 208 may determine the application information based on the information received from requester 206. For determining the application information, processor 208 may have access to various data bases, such as for example an application database 210 providing profiles of available applications and including, for example, the respective URIs and descriptions. Further, a meta database 212 providing information on meta data related e.g. to the channels and/or programs may be accessed by processor 208, and a rule set database 214 including, for example, legal regulations and provider regulations for determining which applications are available and/or allowable, e.g. recommended, for execution under predetermined circumstances.
For example, based on the triplet information, processor 208 may determine the channel and may determine the program currently displayed on the channel. Processor 208 may then query metadata base 212 for obtaining meta data related to the program currently displayed. Based on the meta data, processor 208 may then query application database 210 for identifying applications that may be of interest for a user watching the respective program. Based on the result, processor 208 may further query rule set database 214 for determining all applications that may be allowable for execution while the respective channel and/or program is being displayed. Processor 208 may then provide a list of available and/or allowable applications as application information.
In any of the database queries of processor 208, the further information transmitted by request 204 may be used.
For example, information on the provider of the channel may be used for querying rule set database 214. It may, for example, be determined by the provider that while watching one of the provided channels, any applications related to channels of other providers should be excluded from execution.
Further, the device information may also be used for querying rule set database 214, where it may be determined that for devices with predetermined hardware restrictions, only applications that are adapted to run under the respective restrictions should be proposed. For example, the application logic may be restricted to a predetermined complexity, the application data to a predetermined amount of data, and communication requirements to the network capacity or a communication bandwidth.
Further, the subscriber number may be used for determining applications to which the user of television apparatus 200 has subscribed or for which the user has paid. Thereby, access to certain applications may only be allowed if a respective fee has been paid.
Information on the user profile may be used for determining applications of special interest to the user, e.g. by querying application database 210 or meta database 212, which may also include meta data related to the applications. Further, access to applications may also be restricted depending on the user profile, thereby implementing requirements of parental control.
Further, application information may also be determined based on the local time, e.g. by querying application database 210. For example, in the early morning, applications providing information on airport or train schedules may be of particular interest, while at noon, applications related to cooking recipes may be preferred.
Additionally, information on the location of television apparatus 200 may be used for determining applications that may be of special interest at the location, such as location-based advertisings of theatres, shops, food delivery services or the like. For example, an application may be selected that may enable the user to order food from a local food delivery service. The location of television apparatus 200 may also be used for determining a language to be used by the application and for determining applications provided for certain regions or countries, such as country-related sports information.
Further, the applications to be run at television apparatus 200 may also be parameterized by the location. For example, an application informing the user about the weather forecast for the next days may be parameterized with the postal codes of the city the user lives in.
After having determined the set of allowable and/or recommended applications based on the information provided with request 204, processor 208 may generate the application information, e.g. in form of a list. The list may be published to television apparatus 200 by a publisher 216 of application information server 202 as a response 218. Publisher 216 may also publish further lists in response to the request of any client television device of the above mentioned a population of client television devices.
Response 218 published to television apparatus 200 may include the list of all allowable and/or recommended applications that may be of interest for the user. The list may further include, for each of the applications, an identifier, such as “BBCNewsTicker”, an application class, such as “informational”, “promotional” or “interactive”, and an address, such as an URI, for accessing and/or downloading the application, e.g. application logic and/or application data.
Further additionally, response 218 may include control information for controlling display and execution of the respective. For example, the control information may define an application or a part of an application which is to be included or excluded from execution under circumstances defined by request 204. Further, the control information may define a part of data of the application which is to be included to or excluded from being displayed.
For example, this could be an inclusion/exclusion of content in view of parental control requirements, excluding content which is not suitable for display to a child of a certain age, which child may be identified by a personal user profile and/or a personal, e.g. password-protected “log-in” to the television apparatus. Further, the age of the child may be determined based on the program being watched.
Further, advertisings embedded into the television application may also be included or excluded from being displayed in accordance with demands of a television manufacturer of television apparatus 200 or of a channel provider of the channel being viewed.
For example, if television apparatus 200 is of a predetermined brand X, the manufacturer of television apparatus 200 may want to exclude any advertisings from his competitors, e.g. to exclude all advertisings for a competing brand Y.
As a further example, a broadcaster or channel provider may want to exclude any competitor adverts from appearing while a channel provided by the broadcaster is displayed at television apparatus 200. For example, a provider of a channel 1 may demand that no advertisings for events on a channel 2 may appear while viewing channel 1.
Determination of control information may be based on the rules defined in rule set database 214. It may be defined in view of any data submitted with request 204. For example, the control information may depend on the channel currently displayed at television apparatus 200, the program currently aired by the channel, the provider of the channel and/or the manufacturer of the television apparatus. Further, the control information may be defined for applications, for parts of applications such as application data and/or content, for an entirety of all applications referenced in response 218, and/or for all applications that may be run at television apparatus 200. This allows thoroughly controlling all application content displayed at television apparatus 200 in view of various demands and regulations.
The control information may include or consist of a “black list”, the black list being descriptive of the applications, parts of applications or application data to be excluded from being displayed. Defining the control information as a black list may allow an easy implementation of content control at television apparatus 200, since excluding data from being displayed may be realized by a simple comparison process.
In order to achieve content inclusion or exclusion, control information may be defined by content control markers used for marking the application content, thereby determining which application content is to be included for or excluded from being displayed. The content control markers may therefore be included into the application logic and/or application data, thereby assuring that the marked content is included to or excluded from being displayed.
Consequently, control information enables an effective and efficient control of the content displayed at television apparatus 200 by defining text, video and/or audio content to be included to or excluded from display. Thereby, provider requirements, legal regulations and parental control may be guaranteed.
The system includes a television apparatus 300 (broadcast television receiver apparatus) connected over the internet to an application control server 302 and to a first, second, and third television application servers, which television application servers are respectively provided by a first, second, and third television application providers.
Television apparatus 300 includes a tuner 310 which is capable of tuning to a channel transmitted by a broadcast signal 312, broadcast signal 312 being provided by a terrestrial broadcasting station 314, a broadcasting satellite 316 or by a cable provider 318.
On a certain event occurring at television apparatus 300, like an activation of a television application catalogue or a channel switch of the channel tuned to and/or displayed, a first process 319 may be performed. Within first process 319, the channel information may be published to application control server 302. For connecting to application control server 302, a connection 320, e.g. an Ethernet or WiFi connection, may be established, and a query 322 including the channel information may be sent to application control server 302 via the internet.
The channel information, as in the example depicted, may be defined by a channel identifier which may, for example, include the triplet information. Further supporting information may also be published to application control server 302, supporting the identification of allowable television applications. The further supporting information may include program information identifying a program currently transmitted at the channel, for example a program identifier included in service information of broadcasting signal 312, e.g. DVB-SI of a DVB-T/S/C signal. Further, the supporting information may include device identification information, e.g. defined by a device identifier, including, for example, a serial number, a MAC address, a device type or a model of television apparatus 300. Further, the local time may be included in query 322. Further, an IP address of the connected Ethernet port may be included.
Query 322 may be received by a requester 324 provided as a part of application control server 302, requester 324 implementing the listener process for capturing queries of client television apparatuses. Application control server 302 may then perform a second process 325, including analyzing query 322 for identifying the channel to which television apparatus 300 is currently tuned to, e.g. by analyzing the channel information. Further, the program identifier, device identifier, and the further supporting information may also be used for establishing criteria for television application selection within second process 325, as will be explained in detail below.
The television application selection may be performed by a television application linking engine 326 at application control server 302. At television application linking engine 326, a rule set may be implemented for defining the criteria for the television application selection. The selection may be carried out by identifying the channel and/or program currently displayed at television apparatus 300, by identifying meta data related to the program and to the provider of the program, by querying television application linking engine 326, by retrieving a list of allowable and/or available, e.g. related applications, such as widgets, gadgets, applets or further applications adapted to be run on television apparatus 300, and by retrieving the uniform resource identifiers (URIs). Further, television application content control markers may be retrieved, e.g. in accordance with the rule set implemented in television application linking engine 326.
After having determined the allowable and/or available television applications, the result may be published to television apparatus 300. For publishing the results, a response 328 may be generated and sent to television apparatus 300 over the internet. Response 328 may include television application identifiers identifying the television applications allowable and/or available for execution in connection with the channel and/or program currently displayed at television apparatus 300. Further, television application descriptors including, for example, a title and/or a description of the television application may be included. Further, television application batch URIs identifying a respective television application server from which the television application may be retrieved may be included. Additionally, the control information defined by television application content control markers may be included.
At television apparatus 300, a third process 329 may be preformed. Third process 329 may include displaying the data received with response 328 to the user, thereby informing the user about television applications available and/or allowable for execution in connection with the channel and/or program being watched. Further, the user may be enabled to select and retrieve a desired television application for execution, e.g. in a television application environment/executor 330.
For retrieving a desired application, one or more of the first, second and third television application servers 304, 306, 308 may be accessed over the internet, e.g. by using the URIs published with response 328, and the respective application may be downloaded. Further, an execution of the application within television application environment/executor 330 may be started.
During the execution, the video image displayed at the display of television apparatus 300 may be shrunk, such that a graphical user interface of the application selected may be displayed in connection with the program/channel currently displayed. Alternatively, the application may also be performed in the background, or the graphical user interface may be restricted to a small part of the display, located for example in a corner or at a border of the display. Further alternatively, the graphical user interface of the application may also be displayed, e.g. in a transparent manner or as an overlay on a video image currently displayed at the channel.
When executing the application, television application environment/executor 330 may refer to the control information and/or television application content control markers, e.g. a black list, thereby assuring that television application content is included or excluded in accordance with the control information determined at application control server 302. Consequently, content that is accessed within the television application may be controlled in accordance with the rules as determined at television application linking engine 326.
In the example, a channel provider 400, such as BBC™, allows and/or suggests television applications a 402 and b 404 to be executed when any of the BBC™ channels or programs is being watched. This may be defined by link records 406 and 408, respectively.
Further, when watching any program of a channel 410 provided by channel provider 400, in the example bbc2™, television application e 412 is suggested and/or allowed for execution, as illustrated with a further link record 416.
Still further, when watching program 414, i.e. program 003 on bbc1™, television application g 418 is further suggested and/or allowed for execution, as illustrated with a still further link record 418.
Consequently, when watching program 414, i.e. program 003 on bbc1™, then the television application linking engine 326 will include television applications a 402, b 404, and g 418 as television applications allowed and/or suggested for execution in the application information, e.g. in the list included in response 218 of
