Description:
[0001]    The present application claims the benefit of Chinese Patent Application No. CN200710074705.8, filed in China on May 31, 2007, which is incorporated herein by reference. 
       BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates to television. More specifically, the present invention relates to a hardware and software activating device and the methods thereof. 
         [0004]    2. Discussion of the Related Art 
         [0005]    With the development of technology, apart from the traditional ways such as television, set-top-box, etc., people can watch television programs through some newly invented devices like television card, mobile phone with television, and so on. As the combination of internet, TV net and telecommunication net accelerates its development, the application of television is also greatly broadened. Thus, it inevitably becomes popular to preinstall television function in many types of electronic equipment, the necessary hardware and software of which will need to be offered to the user. In doing so, concerns arise, such as how the hardware and software should be offered, and how the providers involved should be protected, especially those who provide the technology to profit from the user. Considering the development of the market where specialization becomes a trend, technology providers, equipment manufacturers, and software providers will specialize in their own businesses, each offering respective services, bearing risks, and gaining profits. 
         [0006]    At present, there are two types of digital television. One kind of digital television is an ordinary television with an additional television set-top box. Another kind of the digital television is an integrated digital machine. The ordinary television with additional television set-top box is a transitional measure for the current situation, and the integrated digital machine will be the direction of the digital television. 
         [0007]    An integrated digital machine is shown in  FIG. 1 , including: tuner  11 , demodulator  12  to receive the amplified IF signal from tuner  11 , TS demultiplexer  13 , MPEG-2 decoder  15 , image and voice processor  16 , image and voice output module  17 , and the external output modules including PAL/NTSC encoder  14 , external video output  18  and external audio output  19 . The integrated digital machine also includes a MCU (Micro Chip Unit)  20  to receive remote controlling signals from the remote controller  2  and to control the tuner  11 , demodulator  12 , TS demultiplexer  13 , MPEG-2 decoder  15 , image and voice processor  16 , image and voice output module  17 , PAL/NTSC encoder  14 , external video output  18 , external audio output  19 , and E2PROM  21  through the I2C bus (not shown). The difference in transmission standards of the digital television is the difference of tuners. Different transmission standards require different tuners. 
         [0008]    An ordinary television with an additional television set-top box (STB) is shown in  FIG. 2 . The STB  3  includes tuner  31 , demodulator  32  to receive the amplified IF signal from tuner  31 , TS demultiplexer  33 , MPEG-2 decoder  34 , PAL/NTSC encoder  35 , video output  36 , and audio output  37 . The STB also includes a MCU (Micro Chip Unit)  38  to receive remote controlling signals from the remote controller  30  and to control the tuner  31 , demodulator  32 , TS demultiplexer  33 , MPEG-2 decoder  34 , PAL/NTSC encoder  35 , video output  36 , audio output  37  and E2PROM  301  through the I2C bus (not shown). The difference in transmission standards of the digital television is the difference of tuners and demodulators. Different transmission standards require different tuners and demodulators. The broadcast device  4  includes image and voice processing module  43 , image and voice output module  44 , E2PROM  40 , MCU  41  and remote controlling sending and receiving pre-processing module  42 . Through the remote controlling sending and receiving pre-processing module  42 , MCU  41  receives remote controlling signals from the remote controller  5  to control the image and voice processing module  43 , image and voice output modules  44  and the E2PROM  40  through the I2C bus (not shown). 
         [0009]    Several modes are illustrated in the above-mentioned figures. In the mode of  FIG. 1 , all the hardware and software are provided by the equipment manufacturers, with high cost and risk. In the mode of  FIG. 2 , the cost will be slightly lowered since different equipment and its corresponding software can be offered by different manufacturers, and accordingly, the risk will be slightly lowered as well. In television sets, there are increasing amounts of hardware and software, the application of which will involve different standards, the patents of which are not owned by the manufacturers. If the manufacturers integrate these hardware and software into their television sets and provide them directly to the user, they risk infringing the patents of these hardware and software. Also, many of these integrated functions (realized by corresponding hardware and software) have no actual value. For example, consider a high frequency tuner, which is installed in a television set to receive terrestrial broadcast signals. To the user who purchases cable television signals, the high frequency tuner, whose cost together with that of corresponding software adds to the purchase cost for the user, and which increases the chances of infringement for the manufacturer, is useless. In another example, the hardware and software integrated into cell phones and other equipment may be not necessary for some users. Therefore, it is feasible that hardware and software which may or may not be used can be pre-integrated into television sets or other equipment, but certain conditions are set up by the manufacturers of television sets or other equipment to prevent the user from employing such hardware and software. If the need for such hardware and software arises, the user needs to obtain, by himself, a corresponding license before the software and hardware can be used. Alternatively, manufacturers provide a list of optional hardware and software from which the user can choose upon purchase of equipment, or when it is needed. Here, the user purchases the separate hardware and gains permission before use in a television set produced by the manufacturer. The problem of how to achieve user access to software and hardware licenses is presented above. Technology allowing the use of these hardware and software which enable the user to receive television programs is not yet available.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0024]    Reference will now be made in detail to the illustrated embodiments of the present invention, which are illustrated in the accompanying drawings. 
         [0025]    As described above, the high frequency tuner in a television set is not necessary for every user. In this embodiment, the signal receiving device parts of the television are separated. Referring to  FIG. 3 , the television without signal tuning and demodulating part (hereinafter referred to as broadcast device  7 ) includes TS demultiplexer  73 , MPEG-2 decoders  72 , image and voice processor  74 , image and voice output module  76 , and the external output modules, including PAL/NTSC encoder  75 , external video output module  78 , and external audio output module  77 . 
         [0026]    Through remote controlling processing module  80 , MCU  79  receives remote control signals sent by remote controller  9 . In addition, MCU  79  controls TS demultiplexer  72  through I2C bus (not shown), MPEG-2 decoders  73 , image and voice processor  74 , image and voice output module  76 , PAL/NTSC encoder  75 , external video output module  78 , external audio output module  77 , and EEPROM  81 . 
         [0027]    A television signal receiving device is shown as the signal receiving device  6  in  FIG. 3 , including the tuner  61  and demodulator  62 . The tuner  61  is used for the reception of television signals transmitted by terrestrial broadcasting or satellites and for the frequency conversion and filtering of the RF signals. The demodulator  62  is used for the demodulation of the television signals received by the tuner  61 . 
         [0028]    In this embodiment, the tuner  61  and demodulator  62  together constitute an independent television signal receiving device  6 . Televisions manufactured by television manufacturers can only be broadcast device  7  without signal tuning and demodulating parts, i.e., not including a television signal receiving device  6 , as shown in  FIG. 3 . 
         [0029]    For some users that need to use the television signal receiving device  6  to receive wireless signals, they can purchase an independent television signal receiving device  6  to support the use of broadcast device  7 . But before use of the television signal receiving device  6 , it needs to be activated. 
         [0030]    In addition to the television signal receiving device  6 , other hardware can also be separated from the television. Such hardware can be purchased by the user and installed into the television set, or be pre-installed by a television manufacturer in the television. In the latter case, the user will have to activate the pre-installed hardware when he wants to use it, the aim of activation being to obtain permission from the owner of the relevant patents by the user himself (those hardware separated from the television set hereinafter referred to as independent hardware). In this embodiment, the hardware separated from the television set is exemplified by the television signal receiving device  6 . In the application of the present invention to other independent hardware, the principles are basically the same. 
         [0031]    As for the now existing television sets, more and more functions, which are often achieved by the integration of software in the television set, or by the cooperation between specific software and hardware, are provided. But many of the functions may never be used by the user. Therefore, another option is provided in this invention, i.e., a television manufacturer&#39;s pre-integrated functional software (hereinafter referred to as independent software) into the television set. If the user needs to use such a function, the user must first activate the software, and then normal use of the function can be realized. 
         [0032]    In addition to the pre-integrated software in television sets, the software integrated into the independent hardware mentioned above also applies to the present invention, such as the middleware in the television signal receiving device  6 . In other words, the above-mentioned television signal receiving device  6  can be used only after the software and hardware are activated. In certain circumstances, the activation of software and hardware can be completed at one time. Similarly, the activation of television functions in other equipment, such as a mobile phone, applies to the present invention as well. The software applicable to the present invention includes relevant software required for television receiving, operational control, or additional functions. 
         [0033]    Here, the main parts of the television set (not including independent hardware and software, which may have been pre-integrated into the television set, or which may not have been integrated and the user needs to purchase separately, their common feature being that an activation operation is needed before the normal use of them) and other equipment with television software and hardware integrated (such as cell phones with an integrated television function) are collectively referred to as the main equipment. The hardware and software which need to be activated for normal use will be known collectively as independent hardware and software. 
         [0034]    An activating device according to the invention is shown in  FIG. 4 . The activating device includes independent hardware (shown in  FIG. 3  as a signal receiving device  6 ), independent software and hardware activating module, and main equipment (shown in  FIG. 3  as broadcast device  7 ). The independent hardware, as the above-mentioned signal receiving device  6 , is designed to receive and to demodulate the broadcast television signal, then to transmit TS to the broadcast device  7 . The main equipment, broadcast device  7 , is used to receive TS transmitted by signal receiving device  6  and process it, then output audio and video information. Independent hardware and software activating module will activate the independent hardware, signal receiving device  6 , when signal receiving device  6  is connected for the first time to broadcast device  7 . The independent hardware and software activation module can be installed in the signal receiving device  6  or broadcast device  7 , or even set up separately. 
         [0035]    The block diagram of the independent software and hardware activation module is shown in  FIG. 5 , including a communication port and a control module. The communication port is designed mainly to obtain activating guidance information from the signal receiving device  6 , and to be used as channels for transferring information between broadcast device  7  and the control module. 
         [0036]    The control module is mainly used to generate cluing information of activating procedures to guide the user as to how to activate the hardware according to the activating guidance information received from receiving device  6 . The cluing information of activating procedures is sent to the main equipment through the communication port and displayed to guide the activation operation of the user. In addition, the control module is also used to verify whether the user&#39;s activation operation is correct or not and control the functioning of independent hardware (signal receiving device  6 ) according to the test results. 
         [0037]    Before activation, the tuners, the modems and the TS demultiplexer of television signal receiving device  6  cannot work normally in the following ways: completely being unable to work, scrambling signal (users seeing images of low resolution), or intermittent working (users being unable to obtain continuous sound or image), or the hardware being accessible with no charge only for a period of time, and when the free period expires, the television signal receiving device  6  will not work. 
         [0038]    The concrete process of the activation operation can be carried out with a variety of methods. The method adopted in this embodiment of the invention is as follows. The independent software and hardware activating module obtains activating guidance information (including hardware and equipment manufacturers, equipment identification numbers which is given by the hardware manufacturers and only identifies the equipment, corresponding network activating methods or telephone activating methods, and other relevant information) from the signal receiving device  6  through the communication port. The control module generates cluing information of activating procedures according to the activating guidance information, then transmits and displays it on the screen of the television set. 
         [0039]    First, device manufacturers and equipment identification numbers are displayed on the screen of the main equipment, then activating methods prompt the user to choose between network activating methods or telephone activating methods. Next, the approaches to gain an activating code are shown according to the activating method selected by the user. After the user gets the activating code through network or telephone, broadcast device  7  will prompt the user to enter the activating code which will be transmitted to the control module of the independent software and hardware activating module and verified by it. If the activating code is verified, the control module will instruct signal receiving device  6  to work normally. 
         [0040]    The control module in the independent software and hardware module can control the hardware in signal receiving device  6  in the following manner. The independent software and hardware module receives encrypted TS transmitted by the signal receiving device  6 , and decrypts it according to the activating code the user enters before it is transmitted to the broadcast device  7 . If the control module fails to receive the activating code, or receives an incorrect activating code, it cannot decrypt the TS signal, thus the broadcast device  7  cannot process the TS signal normally. 
         [0041]    The procedure of activating the independent software and hardware is shown in  FIG. 6 , including the following steps: 
         [0042]    1. The independent software and hardware activating module obtains the activating guidance information from signal receiving device  6  through its communications port. 
         [0043]    2. The control module of the independent hardware and software activating module generates the cluing information of activating procedures according to the activating guidance information, and through the communication port, transmits to the broadcast device  7  the cluing information of activating procedures which will be displayed on the screen, equipment manufacturers and equipment identification number being shown first. 
         [0044]    3. The broadcast device  7  prompts the user to choose between activating methods that include network activating methods or telephone activating methods; 
         [0045]    4. The broadcast device  7  prompts the user to choose approaches to gain the activating code. 
         [0046]    5. The user gains the activating code according to the chosen activating method, and enters it into broadcast device  7 . 
         [0047]    6. Through the communication port, the broadcast device  7  transmits the activating code to the control module of the independent software and hardware activating module. 
         [0048]    7. The control module of the independent software and hardware activating module verifies the activating code. If the activating code is right, the user goes on with step 8, otherwise, the user goes on to step 9. 
         [0049]    8. The signal receiving device  6  works normally under the control of the control module of independent software and hardware activating module. 
         [0050]    9. The control module of independent software and hardware activating module instructs the broadcast device  7  to prompt the user: “activating code errors, please re-enter the right activating code.” 
         [0051]    The above embodiment explains the activating process of the independent hardware of a television set. As for independent software, it can also be activated through the operation of the independent hardware and software activation device as described above. When users need to use the corresponding function of certain independent software, the television set judges that realizing the function requires activating this software, and the activating guidance information carried by this software will be transmitted to the independent software and hardware activating device, and then sent to the television set through the communication port. Then, the television set will generate a menu of activating procedures according to the activating guidance information, displaying it to users on the screen for them to follow. 
         [0052]    To prevent the software or hardware from illegal use, the identification numbers of the software and hardware are encrypted. And the encrypted identification numbers and their activating codes correspond to each other, both of which are necessary for users to activate the software and hardware. 
         [0053]    Using the above method, the parties involved in television are free to choose their own way to gain profits. For example, making profits by inserting advertisements in the software and hardware. 
         [0054]    It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
