Abstract:
An audio-video display device (AVDD) includes a licensable component providing a licensable function. The licensable function is available to present data on the AVDD without paying a license fee to exploit the licensable function, when the AVDD is in a retail demonstration mode, whereas post-vending of the AVDD the licensable function is available to present data on the AVDD only pursuant to a license fee therefor being arranged.

Description:
[0001]    This application claims priority to U.S. patent application Ser. No. 12/970,215, filed Dec. 16, 2010 and to U.S. provisional patent application Serial No. 61/412,552, filed Nov. 11, 2010. 
     
    
     I. FIELD OF THE INVENTION 
       [0002]    The present application relates generally to tracking activation of licensable components in audio video devices such as TVs using unique product identifications. 
       II. BACKGROUND OF THE INVENTION 
       [0003]    Televisions incorporate a host of technologies to enable a viewer to watch programming from a variety of sources. These sources include terrestrial broadcast sources of analog (using National Television System Committee, or NTSC, format) and digital (using Advanced Television System Committee, or ATSC, format) TV signals. ATSC signals typically use video compression known as Motion Picture Experts Group (MPEG-2) and TVs must consequently support MPEG-2 decompression if they support ATSC programming. 
         [0004]    Cable-provided “basic” television programming can also be, provided in NTSC or quadrature amplitude modulation (QAM) format. Cable-provided “enhanced” programming may also be provided using high definition multimedia interface (HDMI) principles. Likewise, satellite-provided TV signals may be received in HDMI. As well, video from the Internet can be displayed on many modern TVs in a variety of formats, including data over cable service Internet specification (DOCSIS) format. Furthermore, TVs are often configured to support multiple audio formats, including advanced audio coding (AAC), Audio code 3 (AC3), digital theater system (DTS), and so on. And as contemporary viewers know, TVs are expected to support the presentation of electronic program guides (EPGs). 
       SUMMARY OF THE INVENTION 
       [0005]    As understood herein, various TV technologies require license fees to be paid. As further understood herein, many technologies that must be built in to modern TVs to support various program sources may not be used. Nonetheless, license fees for the unused technologies are still paid, unnecessarily cascading cost. 
         [0006]    Accordingly, a method includes determining whether an audio video device is in a retail demonstration mode. Responsive to a determination that the device is not in the retail demonstration mode, the method includes enabling licensing fee triggering of a licensable component such that activation of the licensable component triggers a license fee associated with the licensable component. In contrast, responsive to a determination that the device is in the retail demonstration mode, the method includes enabling activation of the licensable component for demonstration purposes without enabling licensing fee triggering of the licensable component such that activation of the licensable component does not trigger the license fee associated with the licensable component. 
         [0007]    A processor can be associated with the audio video device to activate the licensable component without contacting an activation server. In this embodiment, the processor may present an encryption element to unlock a license code stored in a protected region of a local storage of the audio video device and that is inaccessible without the encryption element, the license code being used to activate the licensable component. Alternatively, the processor can request a server to provide the license code needed to activate the licensable component in the retail demonstration mode at least in part by sending to the server a unique product ID along with the identity of the licensable component sought to be activated. The unique product ID may be a combination of a serial number of the audio video device and a model number of the audio video device. Additionally or in lieu thereof the unique product ID can be a unique encryption key in the audio video device. 
         [0008]    If desired, the processor can present on the display a user interface (UI) configured for enabling a viewer to establish whether the audio video device is in the retail demonstration mode. The UI can present an option to select the retail demonstration mode. In some implementations a retail key must be entered by a viewer into a UI presented on the display to enter the retail demonstration mode. The retail key is provided only to retail outlets such that only by entering the retail key is the audio video device placed in the retail demonstration mode. Failure to enter the retail key prevents the audio video device from being placed in the retail demonstration mode such that if the audio video device is never placed on display in a retail outlet but instead is vended directly out of the box, an end user cannot enter the retail demonstration mode and thereby avoid license fee triggering. 
         [0009]    In another aspect, a TV includes a licensable component for which a license has not been obtained prior to vending the TV. The licensable component provides a licensable feature. A TV display and a processor in the TV controlling the display are also provided. The processor executes software code associated with the TV to actuate the licensable component to provide a presentation on the display in accordance with the licensable feature without implementing a license fee payment therefor at least in part responsive to the TV being in a retail demonstration mode. On the other hand, the processor executes software code associated with the TV to actuate the licensable component to provide a presentation on the display in accordance with the licensable feature and implementing a license fee payment therefor at least in part responsive to the TV being in a post-vending mode. 
         [0010]    In another aspect, an audio video display device (AVDD) includes a licensable component providing a licensable function. The licensable function is available to present data on the AVDD without paying a license fee to exploit the licensable function when the AVDD is in a retail demonstration mode, whereas post-vending of the AVDD, the licensable function is available to present data on the AVDD only pursuant to a license fee transaction therefor being arranged. 
         [0011]    The details of the present invention, both as to its structure and operation, can best be understood in reference to the accompanying drawings, in which like reference numerals refer to like parts, and in which:

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0020]    Referring initially to the non-limiting example embodiment show in  FIG. 1 , a system  10  includes an audio video device such as a TV  12  including a TV tuner  16  communicating with a TV processor  18  accessing a tangible computer readable storage medium  20  such as disk-based or solid state storage. The TV  12  can output audio on one or more speakers  22 . The TV  12  can receive streaming video from the Internet using a built-in wired or wireless modem  24  communicating with the processor  12  which may execute a software-implemented browser  26 . Video is presented under control of the TV processor  18  on a TV display  28  such as but not limited to a high definition TV (HDTV) flat panel display. User commands to the processor  18  may be wirelessly received from a remote control (RC)  30  using, e.g., rf or infrared. Audio-video display devices other than a TV may be used, e.g., smart phones, game consoles, personal digital organizers, notebook computers and other types of computers, etc. 
         [0021]    TV programming from one or more terrestrial. TV broadcast sources  32  as received by a terrestrial broadcast antenna  34  which communicates with the TV  12  may be presented on the display  28  and speakers  22 . The terrestrial broadcast programming may conform to digital ATSC standards and may carry within it a terrestrial broadcast EPG, although the terrestrial broadcast EPG may be received from alternate sources, e.g., the Internet via Ethernet, or cable communication link, or satellite communication link. 
         [0022]    TV programming from a cable TV head end  36  may also be received at the TV for presentation of TV signals on the display  28  and speakers  22 . When basic cable only is desired, the cable from the wall typically carries TV signals in QAM or NTSC format and is plugged directly into the “F-type connector”  38  on the TV chassis in the U.S., although the connector used for this purpose in other countries may vary. In contrast, when the user has an extended cable subscription for instance, the signals from the head end  36  are typically sent through a STB  40  which may be separate from or integrated within the TV chassis but in any case which sends HDMI baseband signals to the TV. 
         [0023]    Similarly, HDMI baseband signals transmitted from a satellite source  42  of TV broadcast signals received by an integrated receiver/decoder (IRD)  44  associated with a home satellite dish may be input to the TV  12  for presentation on the display  28  and speakers  22 . Also, streaming video may be received from the Internet  46  for presentation on the display  28  and speakers  22 . The streaming video may be received at the computer modem  24  or it may be received at an in-home modem  48  that is external to the TV  12  and conveyed to the TV  12  over a wired or wireless Ethernet link and received at an RJ45 or 802.11x antenna on the TV chassis. 
         [0024]      FIG. 2  shows details of an example TV  12 . As shown, the terrestrial signal in ATSC format is input to the TV tuner  16 , as is basic cable in NTSC or QAM format in the event that basic cable is used and the wall cable plugged into the F-type connector  38 . On the other hand, streaming Internet video may be received at a DOCSIS tuner  50  and demodulated/decoded at a DOCSIS decoder/demodulator  52 . Typically, the DOCSIS components are housed separately from the TV  12  but in sortie embodiments may be included in the chassis of the TV  12 . 
         [0025]    The output of the tuner  16 , depending on the signal format received, may be sent to an NTSC decoder/demodulator  54 , or a QAM decoder/demodulator  56 , or an ATSC decoder/demodulator  58 . The output from the NTSC decoder/demodulator  54  can be sent directly to the display  28  and speakers  22  for presentation. On the other hand, the output from the digital decoder/demodulators  56 ,  58  typically is sent to a transport stream demultiplexer  60 , which separates the desired program from other programs in the selected stream and sends the desired program to an MPEG video decoder  62 , which in turn uncompresses the MPEG desired program and sends the uncompressed program to the TV display  28  for presentation. Audio from the demultiplexer  60  may be sent to an audio decoder  64  which in turn sends the decoded audio to the speakers  22  for presentation. 
         [0026]    In contrast to the sequence of decoder/demodulators, demultiplexer, and MPEG decoders discussed above, video from either the STB  40  or IRD  44  is in baseband HDMI when it is received by the TV  12 . Accordingly, the signals from the STB  40  or IRD  44  are sent, directly to the TV display  28  for presentation without further video decompression between the STB  40  or IRD  44  and TV display  28 . Audio from the STB  40  or IRD  44  may still be in a format, e.g., AC3, that requires decoding prior to play on the speakers  22  so the audio may be sent through the audio decoder  64  as shown. Likewise, audio from the ATSC terrestrial source  32  may be in AC3 format and so may be sent through the audio decoder  64 . Internet video from the DOCSIS decoder/demodulator  52  may be sent through the demultiplexer  60  and decoders  62 ,  64  as shown. 
         [0027]    Now referring to  FIG. 3 , at block  66  a user of the TV  12  can be conducted, using onscreen user interfaces (UI), through a set-up routine upon first power on or thereafter from a menu to set up various features of the TV. As an example, the user may be asked, for one or more licensable components within the TV, if the user desires to use that component. This may be done implicitly, e.g., by asking the user if the user wishes to automatically scan the broadcast spectrum to detect channels, in which case it may be inferred that the ATSC decoder/demodulator  58  and MPEG decoder  62  will be required and, hence, that licenses to use those components will be needed. Also, in this latter case it may be inferred that a license to the terrestrial broadcast EPG may be required, whereas such a license would not be required if terrestrial broadcast were not being used as an input source. 
         [0028]    Or again, the user may be given the choice to receive Internet video through the built-in modem  24  or from an external modem  48  and if the latter is chosen, no license need be obtained for the internal browser  26 ; otherwise, a license may be required to use the internal browser  26 . 
         [0029]    Proceeding to block  68 , for each license that is inferred to be required based on the user set-up selections at block  66 , the TV  12  uploads a request for the license over the Internet, for example, or back through a two-way cable system, etc. Or, as explained further below the request may be made by telephone. Regardless of how made, the request typically identifies the component for which a license is required based on user input at block  66  along with a unique identification of the TV, e.g., a hash of the TV model number and serial number, in some embodiments encrypted if desired. The request may be made at set-up time. Alternatively, the request may be cached for later upload when, e.g., an appropriate broadband connection is sensed. In any case, the request may be sent to an Internet server at a prestored Internet address or to a cable head end or to another appropriate licensing entity or agent. 
         [0030]    Block  70  indicates that assuming it passes authentication the TV  12  receives back the license in the form of licensing information, typically a code that must be input to the TV processor  18  to enable or unlock the associated component. The code may be automatically input to the appropriate internal components of the TV at block  72  or the code may be displayed on the TV and the user prompted by means of an onscreen UI to enter the code using, e.g., the RC  30 . Proper input of the code activates the related component within the TV. Block  74  simply indicates that license fee data is maintained and used to generate billing information from the licensing agency to the manufacturer of the TV, and may also be used to generate marketing data as discussed further below. The data may be kept in the TV until uploaded to a licensing entity/agent by means noted above. 
         [0031]      FIG. 4  shows that automatic license determinations may be made outside of a user set-up routine if desired. In the example shown in  FIG. 4 , commencing at decision diamond  76  it is determined whether a predetermined physical condition exists in the TV, e.g., a particular kind of connection, from which it may be inferred what, licensable components will be required. In the example of  FIG. 4 , the physical condition is the presence of a voltage in the automatic gain control (AGC) circuitry of the tuner  16 , which would occur when, for instance, a connection is: made at the TV chassis to the terrestrial antenna  34  or when a cable from the wall is connected to the F-type connector  38 . 
         [0032]    When the tested-for physical condition exists, the logic flows to block  78 , in this example to activate the NTSC demodulator  54 . This is done recognizing that NTSC demodulators typically require no licenses, so to avoid unnecessarily requesting licenses, the signal at the tuner  16  is first tested to determine if it is an NTSC signal. Decision diamond  80  indicates that the test may be whether “noise”, is present in the signal. 
         [0033]    If the test indicates that NTSC signals only are present the logic ends, but otherwise the logic flows to block  82  to activate the QAM decoder/demodulator  56 . If QAM only is detected (by the QAM decoder/demodulator  56  recognizing QAM signals and/or no noise) the logic ends, but if the QAM decoder/demodulator  56  does not recognize the signal, this indicates that the signal is neither QAM nor (from decision diamond  80 ) NTSC, with the inference thus being that the signal is ATSC requiring use of the ATSC decoder/demodulator  58 , which is activated at block  86  to process the signal. At block  88  an uplink is obtained by the TV processor  18  to the above-described licensing entity/agent to obtain the license code discussed above using the unique ID of the TV, and at block  90  the code is received and used as necessary to permit use of the ATSC decoder/demodulator  58 . 
         [0034]    Or, the step at block,  90  can be omitted and the ATSC decoder/demodulator  58  immediately activated on the assumption that the processor  18  is programmed to send a message to the licensing entity/agent that licensing accounting is to be generated after activation of the ATSC decoder/demodulator  58 . 
         [0035]    Yet again, as shown in dashed lines in  FIG. 4  the logic may flow first from decision diamond  84  to blocks  88  and  90  to obtain the licensing “unlock” code and then back to block  86  to activate the ATSC decoder/demodulator  58  using the code, to ensure that no use may be made of the ATSC decoder/demodulator  58  until such time as the licensing entity/agent has been informed of its use, has authenticated the TV for the necessary ATSC license, and has determined that under business rules the license code should be downloaded to fulfill the request. 
         [0036]    Additional example inference rules that may be employed pursuant to automatically obtaining needed component licenses after vending the TV to avoid paying for unnecessary licenses prior to sale of the TV include, if there is ATSC, present, it is less likely that QAM will be found; if ATSC is present, the total number of ATSC channels will be much smaller than the number for QAM channels. Also, when signals are received from an external modem  48 , audio video programming does not require use of the built-in browser  26  and so receipt of video over an Ethernet link without receipt of signals at the internal modem  24  may be inferred to mean that the browser  26  is not in use. 
         [0037]      FIGS. 5-7  illustrate logic that may be used during setup to obtain licenses. Using, e.g., the RC  30 , a person may input  92  a request to conduct auto-scan of available terrestrial or cable or satellite channels from, e.g., an onscreen setup menu presented on an audio video display product  94  (which may be implemented by the TV  12 ). In response, the AV display product sends an activation request for, e.g., the ATSC decoder/demodulator  58  which may include the tuner ID and product  94  ID and/or the decoder/demodulator  58  ID/product  94  ID. Activation of the ATSC decoder/demodulator  58  is executed at  96  using activation codes from one or more licensing, entities/agents such as server  98 , provided the licensing entities/agents determine, based on the information received from the product  94 , that the product is entitled to a license for the requested component. 
         [0038]    A log may be kept by the licensing entities/agents indicating what products and what components in those products have been activated and based on that log, licensing accounting data may be generated for purposes of presenting licensing invoices for activated components to the manufacturer of the product  94 . In any case,  100  indicates that the product  94  receives the activation response, e.g., activation codes, to activate the demodulator/decoder  58  at  101 , which converts the product  94  to an ATSC-capable device. The user may be notified using onscreen notification that ATSC programming may now be viewed using the product  94 . 
         [0039]      FIG. 6  shows an alternative embodiment. Using, e.g., the RC  30 , a person may input  102  a request to conduct auto-scan of available terrestrial or cable or satellite channels from, e.g., an onscreen setup menu presented on an audio video display product  94  (which may be implemented by the TV  12 ). In response, at  104  telephone information including a phone number to a licensing entity/agent is prepared and the user notified  106  of the information by means of, e.g., a user interface or prompt presented on the product  94 . The user enters  108  the information into a telephone, either by speaking the number or by holding the telephone adjacent a speaker on the product  94  for receiving dual tone multifrequency (DTMF) tones from the product that are detected by the telephone and used to automatically dial the number using, e.g., a voice response unit (VRU)  110 . 
         [0040]    Other alternate embodiments involve sending short message service (SMS) messages to a server to send the above information or scanning bar-type codes on the TV or component to send the requisite information to the server to obtain the license. In any case, determining what licenses are needed may be accomplished upon start up and/or periodically during operation. 
         [0041]    Tuner activation is generated at  112  by licensing entities/agents  114  such as Internet servers and the activation code discussed above sent  116  to the VRU  110 , which presents the code to the user to complete the activation process at  120 . Activation of the licensable component, e.g., the ATSC decoder/demodulator  58 , is executed at  101 , which converts the product  94  to an ATSC-capable device. The user may be notified using onscreen notification that ATSC programming may now be viewed using the product  94 . 
         [0042]      FIG. 7  shows another alternative embodiment. Using, e.g., the RC  30 , a person may input  122  a request to conduct auto-scan of available terrestrial or cable or satellite channels from, e.g., an onscreen setup menu presented on an audio video display product  94  (which may be implemented by the TV  12 ). In response, at  124  Internet information including an Internet address of a licensing entity/agent is prepared and the user notified  126  of the information by means of, e.g., a user interface or prompt presented on the product  94 . The user enters  128  the information into, e.g., a home computer  127 . Tuner activation is generated at  130  by licensing entities/agents  132  such as Internet servers and the activation code, discussed above sent  134  to the computer, which presents  136  the code to the user by means of, e.g., a web page or telephone to complete the activation process at  138 . Activation of the licensable component, e.g., the ATSC decoder/demodulator  58 , is executed at  101 , which converts the product  94  to an ATSC-capable device. The user may be notified using onscreen notification that ATSC programming may now be viewed using the product  94 . 
         [0043]    Alternatively, licensing information may be exchanged using short message service (SMS) codes or by using bar codes. To use bar codes the TV can include a camera that images the bar codes on various components, which are interpreted by the processor  18  as identifying information. 
         [0044]    In some instances, if only a limited number (e.g., two) NTSC channels are needed, a limited and less expensive license may be requested, and granted to permit access to only those two channels through the NTSC demodulator with a license, being requested and granted to any component such as a stereo audio decoder should the legacy device (typically, a VCR) use such audio. 
         [0045]      FIG. 8  shows logic that may be executed by a licensing entity/agent computer. Commencing at block  140 , a license request from, e.g., the TV  12  is received at, e.g., any of the above-described servers or head ends, which are programmed with software to execute the logic shown in  FIG. 8 . The unique ID discussed above is looked up at block  142  and the requesting device is authenticated at decision diamond  144  by, e.g., determining if the device is on a list of approved devices. If desired, it may be further determined whether a license for the particular licensable component that is the subject of the request has already been granted and if so, authentication fails. If the requesting device is approved and a license for the licensable component that is the subject of the request has not already been granted, the logic moves to block  146  to send license information, e.g., activation codes, to the requesting device. 
         [0046]    Block  148  indicates that license accounting data is generated pursuant to sending the activation code to the requesting device. This accounting data can be used to effect remuneration from the manufacturer of the requesting device to the licensing authority for the component that is the subject of the request. At block  150  the authorized device database is modified to record the grant of the license. 
         [0047]    Marketing data may be generated at block  152  based on the license grant. As an example, the total number of devices vended with the licensable component may be compared against the number of licenses granted to requesting devices to ascertain usage of the component compared to other components within the requesting device. For instance, it might be noted that 30% of vended devices of a particular TV model ever request activation of the ATSC tuner. This data can moreover be correlated to demographic data obtained during device registration so that, as an example, of the 30% of devices requesting activation of the TV tuner, it can be known which geographic region was more likely to request such activation, or which demographic age group, etc. It may be further ascertained, using device registration information submitted by purchasers, that of the devices requesting activation of the ATSC tuner, for example, 90% of those devices were second or third home TVs that consequently can be inferred to lack a cable or satellite hookup. 
         [0048]    It is preferred that once a licensable component has been activated by obtaining a license for it, it cannot subsequently be deactivated by the user, to avoid multiple license payments for the same component. Accordingly, the TV processor  18  may be programmed to refuse deactivation commands from the user if any are input for any component that has been activated and licensed, at least insofar as deactivation would require another license to reactivate. 
         [0049]    Verification of license may also be provided by the TV processor so that, for example, if a component license is requested by the TV but the corresponding feature never used within some period of time, the TV can retract the license request and any license fees refunded as a result. 
         [0050]    Without limitation, the need for paying for licenses for the following technologies may be determined during TV set-up or subsequently by automatically detecting whether the technologies are being used:

         [0063]    Additionally, production encryption keys and test, encryption keys may be used to permit testing a licensable component in production, pre-sale, without triggering the above-described license request mechanisms. A TV may be placed in a test activation mode used only in the manufacturing or test phase, and if desired the test mode may have a hardwired time out. A test key or keys can be used to activate licensable components and the license request algorithm recognizes a test key and responsive to the recognition does not request a license. The test activation mode may be hardwired to deactivate after a single power cycle and the TV processor may not permit reactivation of the test mode thereafter. Activation of a licensable component thereafter requires a production key which is associated with a license request. 
         [0064]      FIG. 9  shows logic that may be executed to activate a licensable component of an audio video device in a retail store for demonstration purposes without triggering payment of a license fee. Commencing at block  200 , the device  12  is energized and at decision diamond  202  a processor such as the processor  18  determines whether the device  12  is in a retail demonstration mode. If not, the logic flows to block  204  to proceed as described above to implement activation of one or more licensable components, which typically entails licensing fee triggering. 
         [0065]    On the other hand, if it is determined at decision diamond  202  that the device  12  is in the retail demonstration mode, the logic flows from decision diamond  202  to block  206  to activate one or more licensable components in the device  12  for demonstration purposes without triggering a license fee. In one embodiment, in the retail mode the processor  18  activates one or more licensable components without contacting an activation server by, e.g., presenting an encryption element to unlock a license code that may be stored in a protected region of the local storage  22  and that is otherwise inaccessible without the encryption element. The license code is then used to activate the licensable component. Security is provided programmatically in such an embodiment, with the processor being programmed to not present the encryption element to unlock the license code unless the processor determines that the device  12  is in the retail demonstration mode. 
         [0066]    Or, in another embodiment the license code may be stored at a remote server and not in local storage  22 , and in the retail demonstration mode the processor  18  requests the license code as before by, e.g., sending, through the modem  24  or  48  or cable or other communications interface, the unique product ID mentioned above, along with the identity of the licensable component sought to be activated. The unique product ID may be a combination, e.g., a hash, of the device  12  serial number and device  12  model number. Or, the unique product ID may be a unique encryption key in the device  12  such as a high definition content protection (HDCP) key selection vector (KSV) or DTCP certificate. The server compares the unique device  12  ID to a list of authorized device IDs and if a match is found, returns to the processor  18  the license code required to unlock the licensable component. If no match is found, and/or (in some embodiments) if a match is found but the license code has already been requested in the retail mode, the license code is not returned by the server to the device  12 . In this way, the server and, hence, the licensor of the licensable component knows how many times the licensable component has been activated for demonstration purposes and can compare this against the actual fee-generating license request that may eventually be made by a purchaser subsequent to demonstration in accordance with principles above. 
         [0067]    An alternative determination that the device  12  is in a retail demonstration mode may be made by the device  12  follows. The device  12  can receive audio through a microphone connected to the device  12  processor, and if the audio as determined by audio pattern recognition software indicates that multiple sources of audio are playing the same audio simultaneously (as is often the case with multiple TVs in a store being tuned to the same channel), a determination of “retail demonstration mode” at decision diamond  202  may be returned. 
         [0068]    Another alternative determination that the device  12  is in a retail demonstration mode may be made by the device  12  follows. The device  12  can use connectivity, either ad-hoc (e.g., through a local area wireless Ethernet), AP, or mesh technology and discover other similar CE devices in the immediate vicinity and if several are discovered, the device  12  can infer it is in the retail demonstration mode at decision diamond  202 . In this case, only a single brand of CE device need be set up and later-energized CE devices in the vicinity can then detect the first authorized retail CE device in making, their own determinations at decision diamond  202 . Yet a third, alternative is to define (using, e.g., frequency, pulse characteristics, etc.) an industry standard short range RF or IR signal to be a “retail beacon” that is transmitted in retail outlets. When the CE device  12  detects the retail beacon, it determines it is in the retail demonstration mode at decision diamond  202 . 
         [0069]      FIG. 10  illustrates an example non-limiting mechanism, in this case, a UI  208  that is presented on the display  28 , that may be used to establish, whether the device is in the retail demonstration mode. The UI  208  may be presented at power on or at some other point of operation, e.g., when a licensable component is invoked by attempting to present data on the display  28  requiring use of the licensable component. In this latter case the UI  208  may not be presented, if a license to the licensable component has already been purchased but only if no license to the licensable component has been purchased but use of the component is desired or attempted. 
         [0070]    As shown, a viewer is presented with the option of selecting “yes” of “no” with respect to the retail mode, with “yes” meaning that the device  12  is to be determined to be in the retail mode at decision diamond  202  in  FIG. 9  and “no” meaning that the device  12  is to be determined not to be in the retail mode at decision diamond  202  in  FIG. 9 . The viewer may appropriately manipulate the RC  30  to navigate and make selections from the UI  208  in  FIG. 10 . When “yes” is selected, the viewer may be prompted as shown to enter a retail mode key, which is provided only to retail outlets. Only by entering the retail key can the device  12  be placed in the retail mode at decision diamond  202 /block  206 . Failure to enter the key causes the device  12  to be placed in the normal mode at, block  204  after, e.g., a predetermined timeout period during which no authorized key is received even if “yes” is selected from the UI  208 . In this way, in the event that the device  12  is never placed on display in the retail outlet but instead is vended directly out of the box, an end user cannot enter the retail mode and thereby avoid the license activation logic of  FIGS. 1-8 . Additionally, the example UT  208  in  FIG. 10  may further allow a retail store clerk to permanently disable the retail mode upon sale of the device  12 , in which case the UI  208  is never presented again on the display  28  and the device  12  remains in the normal mode at block  204 . Also, the retail mode may be permanently disabled automatically and the device  12  always thereafter remaining in the normal mode upon occurrence of a predetermined condition, e.g., the device  12  has been powered up and retail mode selected and entered by entering an authorized retail key more than a threshold number of times, e.g., twenty.
