Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates generally to the field of interactive television systems. More specifically, the present invention relates to a system and method for providing foreign language support for a remote control device within an interactive television system.




2. Description of Related Background Art




Television and Internet technologies are beginning to converge. In particular, access to the World Wide Web via Internet-enabled television systems is becoming increasingly popular. Internet-enabled television systems, also referred to as interactive television systems, enable users to enjoy a robust set of interactive options not available in conventional televisions. Internet-enabled television systems bring the power of the Internet to a large segment of customers who were previously deterred by the complexities of modern personal computers.




The Internet spans many countries and languages. Thus, interactive television systems should provide support for multiple languages. While software may be easily written to accommodate many different languages, it is more difficult for hardware components, such as remote controls, to be similarly configured. Typically, each remote control includes printed text in a single language. Thus, a speaker of one language is often required to operate a remote control designed for a speaker of another language.




For instance, an individual may be using an interactive television system at a hotel in a foreign country. Such an individual may be hindered by the fact that the buttons of the remote control include text in a foreign language. Likewise, public kiosks incorporating interactive television systems need to support multiple languages, but are typically configured for only one language or a limited subset of languages. Even in the home, there may be individuals who speak different languages, but need to share a common interactive television system.




Conventional solutions, such as applying language-specific stickers to a remote control, are deficient in a number of respects. For example, such stickers may be easily separated from the remote control. In addition, the stickers do not easily accommodate interactive television systems that are frequently used by speakers of multiple different languages, as in the case of a hotel, a public kiosk, or in a multi-lingual home. Continually changing stickers or providing different remote controls for each language is impractical and costly.




Accordingly, what is needed is a system and method for assisting a speaker of a first language in operating a remote control device designed for a speaker of a second language.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




The present invention solves the foregoing problems and disadvantages with a system and method for assisting a speaker of a first language in operating a remote control device designed for a speaker of a second language. In one implementation, an icon representing each of a number of interactive options periodically available within an interactive television system is stored within an icon repository. Each interactive option corresponds to a button on a remote control device, and each icon shares a common visual characteristic with a corresponding button on the remote control device. Examples of shared visual characteristics include shape, color, text markings, graphical markings, as well as a combination of these.




In addition, descriptions, in various languages, of the interactive options are stored in language modules. When an interactive option becomes available, a corresponding icon is displayed on a display device for the interactive television system. In addition, the corresponding description, in a user-selected language, is presented. The description may be presented visually (e.g., on the television) or audibly (e.g., using voice synthesis).




As used herein, the term “remote control” is not limited to conventional remote controls. Rather, the term contemplates a variety of devices that enable a user to operate an interactive television system. Remote controls may include, for example, webpads, cell phones, personal digital assistants (PDAs), wired or wireless keyboards, and the like.




Reference throughout this specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases “in one embodiment” or “in an embodiment” in various places throughout this specification are not necessarily all referring to the same embodiment.




Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided, such as examples of programming, user selections, network transactions, database queries, database structures, etc., to provide a thorough understanding of embodiments of the invention. One skilled in the relevant art will recognize, however, that the invention can be practiced without one or more of the specific details, or with other methods, components, materials, etc. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the invention.




Throughout the following disclosure, the term “coupled” may be used to refer to components that are either directly connected or are linked by one or more other components. Thus, as used herein, the term “coupled” may be synonymous with “in electrical communication with” or simply “in communication with.”




Referring now to

FIG. 1

, there is shown a system


100


for delivering television programs and other forms of content to a plurality of customers. In one implementation, the system


100


includes a broadband communication network


101


, such as a cable network. However, other networks are contemplated, one particular example of which is a satellite network.




In one configuration, the system


100


includes a plurality of set top boxes (STBs)


102


located, for instance, at customer homes. Generally, an STB


102


is a consumer electronics device that serves as a gateway between a customer's television


104


and the network


101


. In alternative embodiments, an STB


102


may be embodied more generally as a personal computer, a television


104


with integrated STB functionality, or another type of client terminal.




An STB


102


receives encoded television signals and other information from the network


101


and decodes the same for display on the television


104


or other display device (such as a computer monitor, flat panel display, or the like). As its name implies, an STB


102


is typically located on top of, or in close proximity to, the television


104


.




Each STB


102


may be distinguished from other network components by a unique identifier, number, code, or address, examples of which include an IP (Internet Protocol) address or media access control (MAC) address. Thus, video streams and other information may be transmitted from the network


101


to a specific STB


102


by specifying the corresponding address, after which the network


101


routes the transmission to its destination using conventional techniques.




A remote control


106


is provided, in one configuration, for convenient remote operation of the STB


102


and the television


104


. The remote control


106


may use infrared (IR), radio frequency (RF), or other wireless technologies to transmit control signals to the STB


102


and the television


104


. Other remote control devices are also contemplated, such as a wired or wireless mouse (not shown).




Additionally, a keyboard


108


(either wireless or wired) is provided, in one embodiment, to allow the customer to rapidly enter text information into the STB


102


. Such text information may be used for e-mail or instant messaging, e.g. text-based chat. In various embodiments, the keyboard


108


may use infrared (IR), radio frequency (RF), or other wireless technologies to transmit keystrokes to the STB


102


.




In one embodiment, each STB


102


is coupled to the network


101


via a head-end


110


or other distribution center. In the context of a cable network, a head-end


110


is generally a centrally-located facility where television programs are received from a local cable TV (CATV) satellite downlink or other source and packaged together for transmission to customer homes. In one configuration, a head-end


110


also functions as a Central Office (CO) in the telephone industry, routing video streams and other data to and from the various STBs


102


serviced thereby. Head-ends


110


may be coupled directly to one another or through the network


101


. In some cases, head-ends


110


may be connected via a separate network, one particular example of which is the Internet


112


.




The network


101


is preferably coupled to one or more television programming sources


114


, which provide television programming for distribution to the STBs


102


. In one configuration, television programs are distributed in an encoded format, such as MPEG (Moving Picture Experts Group). Various MPEG standards are known, such as MPEG-2, MPEG-4, MPEG-7, and the like. Thus, the term “MPEG,” as used herein, contemplates all MPEG standards. Moreover, other video encoding/compression standards exist other than MPEG, such as JPEG, JPEG-LS, H.261, and H.263. Accordingly, the invention should not be construed as being limited only to MPEG.




The network


101


is also preferably coupled to the Internet


112


to provide access thereto by the STBs


102


. The Internet


112


is a “network of networks” and is well known to those skilled in the art. Communication over the Internet


112


is accomplished using standard protocols, such as TCP/IP (transmission control protocol/Internet protocol) and the like.




In one embodiment, the Internet


112


is coupled to one or more content sources


116


. A content source


116


provides access to various forms of content, such as web pages, streaming media, databases, commercial transactions, and the like. For example, a content source


116


may include a commercial e-commerce site, such as Amazon.com®. The content sources


116


may be accessed, for example, using a web browser integrated with an STB


102


. Of course, content sources


116


may also be coupled directly to the network


101


.




The system


100


is preferably capable of providing a variety of interactive options to a user. In one embodiment, an interactive option is a feature of the system


100


that allows a user to interact with a content source


116


while watching programming received from a programming source


114


, accessing another content source


116


, or the like.




For example, one interactive option may allow a user to participate in an opinion poll while watching a presidential debate. Another interactive option may allow a user to purchase an item being currently advertised or displayed. Still another interactive option may allow a user to check his or her e-mail in response to a notification that a new e-mail message has arrived. Yet another interactive option may allow a user to establish a two-way communication channel with a technical support person or a sales representative. The possible interactive options available using the system


100


are endless.




Interactive options may be implemented using various techniques, protocols, and standards. For example, one technique, established by the Advanced Television Enhancement Forum (ATVEF), relies on embedding “triggers” into a television broadcast. Triggers allow content developers, broadcasters, or cable operators to insert real-time prompts and user-selectable links into the video stream. Among other information, a trigger may contain a network address, such as a Universal Resource Locator (URL), that defines the location of content for the interactive option.




Referring now to

FIG. 2

, there is shown an interactive television system


200


according to an embodiment of the invention. As depicted, the system


200


may include an STB


102


, a television


104


(or other display device), a remote control


106


, and, in certain configurations, a keyboard


108


.




The remote control


106


is provided for convenient remote operation of the STB


102


and the television


104


. In one configuration, the remote control


106


includes a wireless transmitter


202


for transmitting signals to the STB


102


and the television


104


. Likewise, the remote control


106


includes a wireless receiver


204


for receiving signals from the STB


102


.




In one embodiment, the wireless transmitters


202


and receivers


204


are configured to use radio frequency (RF) signals. In other embodiments, infrared (IR) or other frequencies along the electromagnetic spectrum may be used. Operational details regarding the wireless transmitters


202


and receivers


204


are generally well known to those of skill in the art.




The remote control


106


preferably includes a number of buttons or other similar controls. For instance, the remote control


106


may include various standard buttons, such as a power button


206


, an up arrow button


208


, a down arrow button


210


, a left arrow button


212


, a right arrow button


214


, a “Select” button


216


, an “OK” button


218


, channel adjustment buttons


220


, volume adjustment buttons


222


, alphanumeric buttons


224


, and the like.




Additionally, the remote control


106


, in one configuration, may includes a number of buttons specifically-designated for activating various interactive options. These buttons may include, for example, a “Help” button


226


, an information button


228


, a “Buy” button


230


, an e-mail button


232


, as well as other buttons


234


,


236


,


238


,


240


designated to activate specific interactive options.




In one embodiment, the remote control


106


includes a microphone


242


for capturing an audio signal. The captured audio signal is preferably transmitted to the STB


102


via the wireless transmitter


202


. In addition, the remote control


106


may include a speaker


244


for generating audible output from an audio signal received from the STB


102


via the wireless receiver


204


.




The various components of the remote control


106


may be positioned in different locations for functionality and ergonomics. For example, as shown in

FIG. 2

, the speaker


244


may be positioned near the “top” of the remote control


106


(when viewed from the perspective of

FIG. 2

) and the microphone


242


may be positioned at the “bottom” of the remote control


106


. Thus, in one embodiment, a user may conveniently position the speaker


244


near the user's ear and the microphone


242


near the user's mouth in order to operate the remote control


106


in the manner of a telephone. In alternative embodiments, as described below, the speaker


244


, the microphone


242


, and/or the video camera


246


may be disposed within the STB


102


, the keyboard


108


, the television


104


, and/or other suitable locations.




Alternatively, or in addition, a hands-free headset


248


may be coupled to the remote control


106


or keyboard


108


. The headset


248


may be coupled using a standard headset jack


250


. The headset


248


may include a microphone


242


and/or speaker


244


. Such a headset


248


may be used to reduce audio interference from the television


104


(improving audio quality) and to provide the convenience of hands-free operation.




In certain embodiments, the remote control


106


includes a video camera


246


, such as a CCD (charge-coupled device) digital video camera. The video camera


246


allows a user to capture and send video signals to the STB


102


. For example, the video camera


246


may capture images of a customer's screen to aid a support technician in resolving the customer's problem. In one implementation, the video camera


246


is in electrical communication with the wireless transmitter


202


for sending the captured video signal to the STB


102


. Various techniques for encoding and transmitting video signals may be used that are well known to those skilled in the art.




The optional keyboard


108


facilitates rapid composition of text messages. The keyboard


108


includes a plurality of standard alphanumeric keys


252


arranged in a suitable format, such as “QUERTY” or “DVORAC”. In one configuration, the keyboard


108


includes a wireless transmitter


202


, similar or identical to the wireless transmitter


202


of the remote control


106


. The wireless transmitter


202


transmits keystroke data from the keyboard


108


to the STB


102


. Additionally, the keyboard


108


may include one or more of the buttons illustrated on the remote control


106


.




In one implementation, the buttons and audio/video components of the remote control


106


are in electrical communication with the wireless transmitter


202


and/or the wireless receiver


204


for communicating with the corresponding wireless receiver


204


and/or wireless transmitter


202


within the STB


102


. Such communication may be according to the IEEE 802.11a or 802.11b Wireless Networking standards, the “Bluetooth” standard, or according to other standard or proprietary wireless techniques. The wireless transmitter


202


and wireless receiver


204


may include various additional components not specifically illustrated but well known in the art.




Referring now to

FIG. 3

, there is shown a physical block diagram of an STB


102


according to an embodiment of the invention. As noted above, the STB


102


includes a wireless receiver


204


for receiving control signals and audio/video signals sent by the wireless transmitter


202


in the remote control


106


.




The STB


102


also includes, in one implementation, a network interface


302


for communicating with the broadband communication network


101


via the head-end


110


. The interface


302


may include conventional tuning circuitry for receiving MPEG (Moving Picture Experts Group) packets for a selected television channel. The interface


302


may also include conventional cable modem circuitry for sending or receiving other types of data. For example, the interface


302


may conform to the DOCSIS (Data Over Cable Service Interface Specification) or DAVIC (Digital Audio-Visual Council) cable modem standards. In one embodiment, a CMTS-DRFI (Cable Modem Termination System-Downstream RF Interface) may be used in conjunction with a CMTS-URFI (Cable Modem Termination System-Downstream RF Interface) to establish two-way communication between the STB


102


and the head-end


110


.




In one configuration, one or more frequency bands (for example, from 5 to 30 MHz) may be reserved for upstream transmission. Digital modulation (for example, quadrature amplitude modulation or vestigial sideband modulation) may be used to send digital signals in the upstream transmission. Of course, upstream transmission may be accomplished differently for different networks


101


. Alternative ways to accomplish upstream transmission include using a back channel transmission, which is typically sent via an analog telephone line, ISDN, DSL, or other techniques.




The STB


102


also preferably includes a CODEC (encoder/decoder)


304


. The CODEC


304


serves to encode signals (such as audio/video signals) into a network-compatible data stream for transmission over the network


101


. The CODEC


304


also serves to decode a network-compatible data stream received from the network


101


. As depicted, the CODEC


304


may be implemented as a hardware component. Alternatively, or in addition, software encoding and decoding may be used. The CODEC


304


may use various algorithms, such as MPEG, for encoding and decoding.




The STB


102


further includes a memory device


306


, such as a random access memory (RAM), configured to store data for temporary use. Similarly, a read-only memory (ROM) may be provided for storing more permanent data, such as fixed code and configuration information.




In one embodiment, an audio/video (A/V) controller


308


is provided for converting decoded digital audio/video information into analog signals for display/playback on the television


104


or other devices. The AN controller


308


may be implemented using one or more physical devices, such as a separate graphics and audio interfaces. In alternative embodiments, the AN controller


308


may provide a direct, digital video output for televisions


104


or other devices equipped to receive the same. Preferably, the A/V controller


308


includes graphics hardware for performing bit-block transfers (bit-blits) and other graphical operations. Additionally, the A/V controller


308


preferably includes hardware components for generating voice synthesized sounds from digital or analog input signals.




In some implementations, the STB


102


may include a storage device


310


, such as a hard disk drive or the like. The storage device


310


may be configured to record encoded television broadcasts and retrieve the broadcasts at a later time for decoding by the CODEC


304


and display by the AN controller


308


.




The storage device


310


may also be used in various embodiments to store viewer preferences, parental lock settings, electronic programming guide (EPG) data, programming preferences, passwords, e-mail messages, and the like. In one implementation, the storage device


310


also stores an operating system (OS) for the STB


102


, such as Windows CE® or Linux®.




A CPU


312


controls the operation of the STB


102


, including the other components thereof, which are coupled to the CPU


312


via a bus


314


. The CPU


312


may be embodied as a microprocessor, a microcontroller, a digital signal processor (DSP) or other device known in the art. As noted above, the CPU


312


may perform logical and arithmetic operations based upon control signals generated by the remote control


106


and transmitted to the receiver


204


.




Of course,

FIG. 3

illustrates only one possible configuration of an STB


102


. Those skilled in the art will recognize that various other architectures and components may be provided within the scope of the invention. In addition, various standard components of typical STB


102


are not illustrated in order to avoid obscuring aspects of the invention.




As depicted in

FIG. 2

, the buttons and other controls on the remote control


106


and/or keyboard


108


can be highly complicated and overwhelming, particularly to a novice user. Often, simply finding the correct button for executing a command or accessing an interactive option may be a challenge. The problem is compounded by the fact that text markings on buttons of the remote control


106


may be in a language other than the user's primary language.




Conventionally, the challenge may be handled by including fewer buttons on the remote control


106


, or by using translation stickers affixed to the buttons. However, fewer buttons requires various buttons to serve multiple roles, which can be annoying to advanced users. Also, translation stickers may fall off or require frequent changing. Alternatively, help screens and printed manuals may be provided to assist foreign language users. However, for certain interactive options, a user may not have time to consult a help screen or printed manual before the option is no longer available. The limited availability is even more troublesome when a user experiences a language barrier.





FIG. 4

is a logical block diagram of a system


400


for assisting a speaker of a first language in operating a remote control device designed for a speaker of a second language that resolves the above-described problems and disadvantages of conventional approaches. As explained more fully hereafter, the depicted system


400


provides an intuitive mechanism for instructing a speaker of a first language how to use a remote control


106


including printed text in a foreign language. The depicted logical components may be implemented using one or more of the physical components shown in FIG.


3


. Additionally, or in the alternative, various logical components may be implemented as software modules stored in the memory


306


and/or storage device


310


and executed by the CPU


312


.




In one embodiment, the system


400


includes an icon repository


402


for storing a plurality of icons


404


. An icon is a small picture that typically represents an object or program within a GUI.




In the context of the following description, an icon


404


represents a button on the remote control


106


and shares one or more visual characteristics with the button it represents. For example, the icon


404


may have the same shape as the corresponding button. Likewise, the icon


404


may be the same color. Furthermore, the icon


404


and the corresponding button may share similar graphical or textual markings. For example, as shown in

FIG. 4

, a text marking “Compra”, indicating “Buy” in Italian, may be used on an icon


404




a


corresponding to the buy button


230


.




In one embodiment, the icon


404


and the corresponding button may share multiple visual characteristics, such as both shape and color, or shape and text markings. The correlation of multiple visual characteristics can be a powerful visual cue to a user in locating the correct button on the remote control


106


.




Icons


404


in the repository


402


may be stored in various standard formats, such as bitmaps, JPEG (Joint Photographic Experts Group) images, GIF (Graphic Interchange Format) images, TIFF (Tagged Interchange File Format) images, etc. The icon repository


402


may be implemented using any suitable data structure, such as an array, linked list, stack, queue, disk file, or the like. The data structure implementing the icon repository


402


may be stored in the memory


306


or the storage device


310


. The icon repository


402


may include an index (not shown) to provide faster storage and retrieval of icons


404


within the icon repository


402


.




In one embodiment, one or more icons


404


may correspond to particular interactive options


408


that may be periodically available during the presentation of television programming


409


or other forms of content (such as web pages, user interfaces, or the like) on the television


104


. Each interactive option


408


may be facilitated by one or more interactive option modules


406


configured to provide the appropriate functionality.




In one configuration, an interactive option module


406


detects the availability of the interactive option


408


. This may be accomplished, in one embodiment, by detecting a trigger received with the television programming


409


. For example, the interactive option module


406


may detect an ATVEF trigger containing a link to an advertiser's site.




The system


400


may also include an icon display module


410


, which is in communication with the interactive option module


406


. After the interactive option module


406


detects that the interactive option


408


is available, the icon display module


410


instructs the user as to which button of the remote control


106


should be pressed to activate the option


408


. In one configuration, the icon display module


410


retrieves an icon


404


corresponding to the option


408


from the icon repository


402


and displays the icon


404


on the television


104


(or other display device).




The system


400


may also include a language assistant


414


, which is in communication with the interactive option module


406


. In one embodiment, the language assistant


414


includes, or is in communication with, one or more language modules


416


. A language module


416


may be embodied as a collection of descriptions


422


, in a particular language, of interactive options


408


and corresponding icons


404


in the icon repository


402


. A description


422


may include a translation of text found on the corresponding icon


404


or button on the remote control


106


, although this is not a requirement. For example, descriptions


422


may be provided where an icon


404


or button does not include text.




Those of skill in the art will recognize that a single language module


416


may store descriptions


422


in a plurality of languages. Alternatively, a separate language module


416


may be used to store descriptions


422


for each language.




In certain embodiments, a language module


416


may be implemented as a data structure that is loaded into memory


306


of the STB


102


. Alternatively, one or more language modules


416


may be accessible at the head-end


110


or at various other locations in the network


101


or Internet


112


.




In one embodiment, a user may specify a selected language


418


by means of a language selection module


420


. The language selection module


420


may be implemented using any conventional user interface technique. For instance, a user may select from a menu (not shown) of possible languages. The selected language


418


may be the same as, or different than, the language associated with the remote control


106


.




If the selected language


418


is different than that of the remote control


106


, when an icon


404


is displayed in response to the availability of an interactive option


408


, the language assistant


414


presents the corresponding description


422


in the selected language


418


. The description


422


assists the user who speaks the selected language


418


in understanding what interactive option


408


is available by pressing the button of the remote control


106


indicated by the icon


404


. As noted, descriptions


422


may include a translation of text markings that appear on the icon


404


or the button on the remote control


106


.




In one configuration, the language assistant


414


retrieves the description


422


from the appropriate language module


416


and displays the description


422


on the television


104


(or other display device) in close proximity to the icon


404


. The icon


404


and description


422


may be superimposed over the displayed programming


409


using a semitransparent graphical overlay. This prevents the icon


404


and/or description


422


from obscuring the programming


409


. The icon display module


410


and language assistant


414


may include, or be in communication with, the A/V controller


308


of

FIG. 3

in order to combine the display of the icon


404


and description


422


with the programming


409


using conventional techniques.




Displaying the icon


404


both notifies the user as to the availability of the interactive option


408


and instructs the user concerning the appearance (and possibly the location) of the corresponding button on the remote control


106


. Hence, the icon


404


is sometimes referred to herein as an “instructional” icon for a user interface.




Displaying the description


422


provides meaning for the icon


404


to a user who speaks a language other than the language for which the remote control


106


was designed. Consequently, the user may desire to locate the button on the remote control


106


and activate the available option


408


. Without the description


422


, the icon


404


will be of little assistance to, and may actually annoy, a user who speaks a different language.




In addition, in certain embodiments, the description


422


conveys the meaning intended by text markings on an icon


404


. When a description


422


provides a translation of text markings on an icon


404


, the text markings of the icon


404


serve the foreign language user as graphical markings to assist in locating the corresponding button. For instance, Chinese text markings on a button displayed with a description


422


translating the text may provide effective visual cues to assist a user in locating the button on a Chinese remote control.




As an example, suppose the remote control


106


includes text markings in Italian, e.g. button


230


includes “Compra” in place of “Buy”. When a particular product is displayed, the programming


409


may include a trigger for an interactive option


408


enabling a user to purchase the displayed product by pressing the “Compra” button


230


.




However, suppose a user has specified English as the selected language


418


. In one implementation, the icon display module


410


retrieves and displays the icon


404




a


from the icon repository


402


corresponding to the “Compra” button


230


. At essentially the same time, the language assistant


414


retrieves the corresponding description


422




a,


e.g. “Buy”, corresponding to the icon


404




a


from the English language module


416


. In one embodiment, the language assistant


414


displays the description


422




a


on the television


104


in close proximity to the icon


404




a.


Broken lines in

FIG. 4

indicate the relationship between the “Compra” button


230


, the interactive option


408


, the icon


404




a


and the description


422




a.






As shown in

FIG. 4

, the icon


404




a


has the same shape as the “Compra” button


230


, e.g. a squashed oval. Moreover, both the icon


404




a


and the “Compra” button


230


include similar text markings, e.g. the word “Compra.” Furthermore, the description


422




a


provides a direct translation of the Italian word “Compra” into its English equivalent, “Buy.” The similarity of the shape and textual markings of the icon


404




a


with the translation provided by the description


422




a


may assist the user in rapidly locating the “Compra” button


230


on the remote control


106


. Additionally, the description


422




a


assists the user in deciding whether activating the “Buy” interactive option


408


is desirable.




In an alternative embodiment, the system


400


may include an audio component


424


in communication with the language assistant


414


. As described in greater detail below, the audio component


424


allows the language assistant


414


to present audible descriptions


422


(in a user-preferred language) in addition to, or in lieu of, visual descriptions


422


. For example, the audio component


424


may use a voice synthesis module


425


to output a spoken version of a description


422


. Various text-to-speech voice synthesis systems are available from Lucent®, Creative Labs®, and others.




While the icon repository


402


, the icon display module


410


, the interactive option module


406


, the audio component


424


, and the language assistant


414


are illustrated as components of the STB


102


, those skilled in the art will recognize that these components may be located within various physical locations within the system


100


. For example, a single icon repository


402


may be implemented within a head-end


110


and provide icons


404


to a plurality of STBs


102


. Additionally, a language assistant


414


may reside on a server (not shown) connected to the Internet


112


.




In one embodiment, the language assistant


414


is configured to display the description


422


at various locations on the television


104


in relation to the icon


404


. As shown in

FIG. 5

, the description


422


may be displayed above, below, to the left, or to the right of the icon


404


. In one configuration, the language assistant


414


may actually replace text markings on the icon


404


with a translated description


422


.




In certain configurations, the description


422


may be visually emphasized by highlighting, illuminating, pulsing, or otherwise emphasizing the description


422


. In the depicted embodiment, description


422




a


is bolded to attract the user's attention. Visual emphasis may also be accomplished, for example, by cycling colors of the description


422




a,


changing the color of the display screen behind the description


422




a,


or other similar techniques.




As also shown in

FIG. 5

, the displayed description


422




a


may be larger than the text markings of the icon


404


. This may be helpful to users who have impaired vision. Typically, at least some enlargement of text markings is necessary, since the low resolution of a television screen makes small text and graphics difficult to understand.





FIG. 5

also shows a language button


502


, e.g. “Lingua” in Italian. In certain embodiments, the language button


502


may be used to change the selected language


418


discussed in relation to FIG.


4


. In this manner, a foreign language user may quickly set the selected language


418


and receive descriptions


422


in the user's preferred language.




In one embodiment, when a user activates a button corresponding to a displayed icon


404


, the system


400


produces an audible confirmation. The audible confirmation may be used to assure the user that the correct button was pressed on the remote control


106


. The AN controller


308


of

FIG. 3

may be configured to produce an audio signal when the correct button is activated. The audio signal may include, for example, a chime, a tone, a beep, or other suitable indicator. In one embodiment, the audio signal may include a spoken name of the button, in the selected language


418


, which may be generated using conventional voice synthesis techniques.





FIG. 6

illustrates an alternative embodiment of the invention in which a description


422




a


is presented both visually and audibly. The description


422




a


may include alternative audible messages


602


,


604


,


606


to assist the speaker of a language other than the default language of the remote control


106


. These messages


602


,


604


,


606


may be played on a speaker associated with the television


104


, the STB


102


, or another suitable location.




The system


400


may be configured to provide a word message


602


, e.g. “Buy”, a phrase message


604


, e.g., “Buy the displayed item,” or an instructional message


606


, e.g., “Please press the “Buy” button to purchase the displayed item.” The instructional message


606


may be particularly useful, in that it may provide step-by-step instructions, in the user's preferred language, concerning the operation of the remote control


106


.




In some embodiments, a map


702


of the remote control


106


(or a portion thereof) is displayed in order to help the user locate a particular button, as illustrated in FIG.


7


. The map


702


may include a plurality of icons


404


from the repository


402


, which are arranged according to the relative locations of the corresponding buttons on the remote control


106


. The map


702


may include other graphical elements, such as a semitransparent outline of a remote control to provide a context for the displayed icons


404


. In addition, the map


702


may contain icons


404


corresponding to buttons that are not used for interactive options


408


, such as, for example, the power button


206


. In one embodiment, the map


702


is displayed by the icon display module


410


.




An icon


404




a


corresponding to a currently available interactive option


408


may be visually emphasized within the map


702


through highlighting, animation, scaling, or the like. This allows the user to rapidly determine the location of the corresponding button within the remote control


106


.




Moreover, the description


422




a


of the interactive option


408


may be displayed in connection with the icon


404




a,


as previously described. The description


422




a,


likewise, may be visually emphasized using the techniques discussed above to bring the same to the attention of the user. For example, as shown in

FIG. 7

, the description


422




a


associated with the icon


404




a


corresponding to the “Compra” button


230


may be cyclically scaled (e.g., enlarged and reduced) in an animated fashion to attract the user's attention. Alternatively, the description


422




a


may be rotated, translated, or the like. Of course, the illustrated animation is merely exemplary, and many other techniques for animation may be used.




The size and location of each icon


404




a


within the map


702


is preferably relative to the size and location of the corresponding button of the remote control


106


. Thus, to locate a button of the remote control


106


, a user may compare the size and location of a displayed icon


404




a


corresponding to an available interactive option


408


with the size and location of corresponding buttons of the remote control


106


.




Of course, the map


702


need not correspond to the entire remote control


106


. For example, the map


702


may represent only the “top” or “bottom” halves of the remote control


106


, or some other discrete portion thereof.




In one embodiment, as shown in

FIG. 8

, a user may switch between an icon view


802


and a map view


804


. The icon view


802


may correspond to the embodiments shown in

FIGS. 4-6

in which an icon


404


representing an available interactive option


408


is displayed with a description


422


. The map view


804


may correspond to the embodiment depicted in

FIG. 7

in which a map


702


is displayed.




In one embodiment, the icon view


802


may be the default view, with the map view


804


being displayed only in response to a user pressing an appropriate button on the remote control


106


, such as a “View” button


806


. For remote controls


106


designed for specific languages the “View” button


806


may include text markings in a default language such as Italian, e.g. “Guardar.” A speaker of a language other than the default language may learn the function of the “Guardar” button


806


through minimal assistance, translated manuals, or on-line help. Alternatively, the map view


804


may be the default view. The “View” button


806


may be configured to toggle the display between the icon view


802


and the map view


804


in various embodiments.




Referring now to

FIG. 9

, there is shown a flowchart of a method


900


for assisting a speaker of a first language in operating a remote control device


106


designed for a speaker of a second language. The method


900


begins by storing


902


in a repository


402


an icon


404


for each of a plurality of interactive options


408


available at various times within a system


400


. In addition, a description


422


, in the first language, is stored


904


with each icon


404


describing the corresponding interactive option


408


.




When an interactive option


408


becomes available, an icon


404


corresponding to the interactive option


408


is retrieved


906


from the repository


402


. In addition, a language assistant


414


retrieves a corresponding description


422


from a language module


416


corresponding to the preferred language of the user. Thereafter, the icon


404


is superimposed


908


, in one embodiment, over currently-displayed programming


409


or other displayed content. Next, the description


422


is presented


910


, in one embodiment, by displaying the description


422


in close proximity to the icon


404


. Additionally, an audible message


602


,


604


,


606


may be presented to the user via conventional voice synthesis techniques.




As noted previously, a user may switch between a map view


804


and an icon view


802


of the icon


404


and description


422


by pressing an appropriate button, such as a “View” button


806


. In certain configurations, the icon


404


and/or description


422


may be visually emphasized to attract the user's attention. Various types of visual emphasis are contemplated, such as highlighting, animation, scaling, etc.




A determination


912


is then made as to whether the user has selected the available interactive option


408


using the remote control


106


, e.g. was the correct button pressed. If so, an audible confirmation is generated


914


to alert the user to the fact that the correct button was pressed. The interactive option


408


is then activated


916


using conventional techniques.




Based upon the foregoing, the present invention offers numerous advantages not available in conventional interactive television systems. In response to an interactive option becoming available, an instructional user interface icon is displayed to assist a user in identifying and/or locating a corresponding button on the remote control. In addition, a description accompanies the icon when the user speaks a language other than the default language of the remote control. The description provides meaning for the icon and may generate interest for activating the interactive option. Each icon shares a common visual characteristic with a corresponding button, such as shape, color, text markings, graphical markings, size, relative position, and the like. Accordingly, the user is not required to read a translated printed manual or an on-line help screen to make use of an interactive option.




While specific embodiments and applications of the present invention have been illustrated and described, it is to be understood that the invention is not limited to the precise configuration and components disclosed herein. Various modifications, changes, and variations which will be apparent to those skilled in the art may be made in the arrangement, operation, and details of the methods and systems of the present invention disclosed herein without departing from the spirit and scope of the invention.
