Title: Wireless extension arrangement for a communications system

Description:
TECHNICAL FIELD OF THE INVENTION  
      THIS INVENTION relates to a wireless extension arrangement for a communications system, and in particular but not limited to, the wireless extension arrangement is for an interactive digital television system which transmits information signals for reception by receivers over a television transmission network and is adapted to receive viewer response signals over a telephone network.  
     BACKGROUND OF THE INVENTION  
      Communications systems such as digital television networks and computer networks (e.g. the Internet) allow bi-directional communication between suppliers and users. They are therefore interactive as the users may respond to any information provided by the suppliers over the communications systems.  
      Many corporations are taking advantage of the interactive nature of the communications systems to promote their businesses and offer for purchase their products and services over the interactive communications systems. Users of the communications systems are encouraged to interactively provide responses such as making inquiries and placing orders over the communications systems.  
      Digital television systems generally have local repeater stations for receiving user responses and forwarding the received responses to a response data centre for distribution to providers. Each repeater station is dedicated to receive responses from users or viewers in a small local area as its reception and capacity are limited. The users or viewers send responses to their respective repeater stations by using their response units to transmit response signals over a radio frequency channel such as a 218 MHz channel. One such system is disclosed in Morales&#39; U.S. Pat. No. 5,872,589.  
      The above interactive television system is costly to set up and maintain, as it requires a large number of repeater stations and response units that must have sufficient transmission power to ensure reception at the repeater stations.  
      In most homes, television sets are located in living rooms, and telephones and their connection sockets are located away from the living rooms. If interactive response signals are to be sent over the telephone lines, telephone extension lines need to be installed to allow telephone sockets to be positioned close to the television sets.  
      Other home or office equipment such as computers, facsimile machines, telephone and telephone related systems, debit and/or credit card processing machines, and the like must be physically connected to telephone outlets if they are to be accessed from a remote equipment. In addition, there are proposals to produce electronic and electrical appliances that can be controlled from a remote computer or telephone. These will require new telephone lines and/or outlets.  
      In Australia three out of every ten families live in rented dwellings. They are reluctant to invest a substantial sum of money for a new telephone socket which cannot be taken away when they leave these dwellings. In addition some land lords may not approve of telephone sockets in sitting rooms. Other families, while they do not have the problem of seeking approval, may be reluctant to invest in new telephone sockets just to use the interactive component of the television systems. The long waiting period of about ten working days for telephone workers to install the new telephone sockets does not encourage families to decide on installing new telephone sockets which are to be used exclusively for interactive responses to a small proportion of television promotions.  
      For countries that are to, or just started to, adopt a television system that allows interactivity, the costs of installing repeater stations or extension telephone lines and sockets alone will be considerable. Also the take up rate of people using the interactivity will be slow due to the added costs of telephone extension line installation.  
      The Internet is another interactive communications system that allows computer users to access information that can be retrieved from web sites located any where in the world. As most of the Internet users connect to their Internet service provider networks using standard telephone lines which have limited bandwidth, the speed of sending and receiving information can be very slow. In fact the speed of information transfer deteriorates further when more people are using the same Internet service providers. Accordingly there is a desire to find a communications system that allows improved transfer of information for Internet users.  
     OBJECT OF THE INVENTION  
      It is an object of the present invention to alleviate or to reduce to a certain level one or more of the above disadvantages.

     DETAILED DESCRIPTION OF THE INVENTION  
      Referring to the Figures and initially to  FIG. 1  there is shown a wireless extension arrangement  10  for communicating signals from a television receiver (TV)  12  to a remote communications terminal (not shown) over a telephone network ( 30  in  FIG. 2 ). TV  12  in this case is located in a sitting room in a residential building.  
      The arrangement  10  has a first transceiver unit  14  which in this case is a digital cordless interface unit (DCIU) and a second transceiver unit  16  which in this case is also a digital cordless interface unit (DCIU). DCIUs  14  and  16  communicates in a RF band that does not interfere with reception of TV  12 .  
      TV  12  has a set top box  18  for receiving digital information signals in the forms of television programs and Internet web pages. The set top box  18  is connected to an external antenna  20  through an antenna connection  22 .  
      DCIU  14  is connected to an output port of the set top unit  18  and a viewer can selectively enter data for to be provided at the output port by means of a remote infrared controller (not shown).  
      DCIU  14  relays the digital data at the output port of the set top unit  18  to DCIU  16  which is located in a different room in the building. DCIU  16  is connected to a modem  24  for converting the data to an analogue form for transmission over the telephone network  30  which is an analogue network. A wall telephone socket  26  is used to connect the modem  24  to the telephone network  30 .  
      DCIU  14  may be incorporated into the set top unit  18  or arranged for wireless communications with the set top unit  18 . Alternatively, the set top unit  18  can be arranged in wireless communication with TV 12 . The modem  24  as shown in  FIG. 1  will not be needed if the telephone network  30  is for digital communications.  
      In  FIG. 2 a  modem  24  is connected between a digital television or a computer and DCIU  14  as DCIUs  14  and  16  are adapted for communicating analogue incoming and outgoing signals.  
      As shown in  FIG. 3  each of the DCIUs  14  and  16  has a transmitter module  32  for transmitting data signals to other DCIU  16  or  14 , and a receiver module  34  for receiving data signals transmitted from the transmitter module  32  of the DCIU  16  or  14 . A tuned RF mixer is provided in each said modules  32  and  34  so that only signals within a specific frequency band can communicate there between. Alternatively the modules  32  and  34  can be replaced by optical sender  36  and optical pickup  38 .  
      The transmitter module  32  and the receiver module  34  are connected to a signal processing module which, on the receiving part, has an intermediate frequency (IF) bandpass filter circuit  40  for filtering carrier frequency of the data signals from the receiver module  34 , and a demodulator  42  for demodulating said filtered data signals. On the transmission part, it has an IF processing circuit  44  for mixing IF with outgoing data signals and a modulator  43  for modulating the mixed signals before transmission. Buffer amplifiers  46  and  48  are provided for buffering respective demodulated (incoming) data signals and the outgoing data signals.  
      A coding arrangement  52  is also provided for encoding data signals for transmission and for decoding received signals. The arrangement  52  gives certain security to transferring sensitive information such as credit card details as any intercepted signal will need to be decoded before its data is known.  
      The information signals from the TV  12  or the remote communications terminal and the incoming data signals are separated in a signal separation circuit  50  for separating signals for forwarding to TV  12  or the remote terminal, and signals for transmission by the transmitter module  32 .  
      The arrangement  10  of the present invention thus allows users to provide interactive responses to invitations on television receivers or computers without having to install costly extension telephone lines and sockets. The television receivers or computers can be located in any convenient locations in a home, and they can be moved from location to location without the need to have new extension telephone lines and sockets.  
      The arrangement  10  also allow broadcasters and datacasters to obtain interactive responses via standard telephone networks and the Internet. This represents a large cost savings as repeater stations are not required. For Internet users downloading of information and programs will be much quicker as television bandwidths allow separate channels for Internet applications.  
      The embodiment of the arrangement  10  shown in  FIG. 4  has a first transceiver unit  14  adapted for wireless communication with a second transceiver unit  16 . The first transceiver unit  14  and the second transceiver unit  16  for this embodiment of the invention are configured for Bluetooth communications, and in this respect the unit  14  has a Bluetooth enabled transceiver module  54  and the unit  16  has a Bluetooth enabled transceiver module  56 .  
      The Bluetooth enabled transceiver module  56  communicates signals received from information or communications sources (not shown) over the telephone network PSTN to a designated one of the appliances  60 , and vice versa. An antenna  55  and an antenna  57  are connected to the respective unis  14  and  16  for extending communications range thereof. To receive signals from the communications sources the unit  16  is provided with a modem  62  which is under control of a processor  64 . The processor  64  also controls the transceiver module  56 . The modem  62  is connected to the PSTN using standard telephone connectors.  
      Similarly, the unit  14  has a modem  68  connected to the module  54  and a processor  66  for controlling operations of the module  54  and the modem  68 . The unit  14  further includes a subscriber line interface circuit (SLIC)  70  for transferring signals to and from the appliances  60 . Power sources  72  and  74  for the respective units  14  and  16  may be any one of the known power supply as indicated in  FIG. 4 .  
       FIG. 5  shows a preferred form of the units  14  and  16  as described earlier. As can be seen, each of the units  14  and  16  has a housing  82  in which the components thereof are located. The housing has an opening  84  for connection of an RJ 11  or RJ 45  connector  86  to a standard telephone interface in the housing  82 . Power connector prongs  88  extend from the housing  82 for connection to a standard power supply outlet  74 .  
      The arrangement  10  has a power pack  80  to provide power to the unit  14  or  16  so that arrangement  10  can be used in places where a power outlet  74  is not available and the power pack  80  can function as a standby power source in the event of power outage.  
      Referring now to  FIG. 6 , the arrangement  10  has a number of first transceiver units  14  called appliance gateway devices (AGD) and a second transceiver unit  16  called a PSTN gateway device (PGD). Each of the AGDs  14  is associated with an electronic appliance or communications apparatus  60 . The AGDs  14  and the PGD  16  have a wireless module  90 , a CODEC  52 , a network controller  66  and a SLIC  70 . The PGD  16 , in this case, also has a modem  92  to enable the appliances  60  to access the Internet and any online communications service. The AGDs  14  has an Ethernet port  94  for connection to a computer network.  
       FIG. 7  shows certain components of an embodiment of the PGD  16  arranged on printed circuit boards  96  and  98 . The components as shown include COIC  71 , CODEC  52 , a power jack  100  for connection to a power supply, a voltage regulator  102  for regulating voltages to the components, memory modules in the form of Flash, SDRAM, and buffer, antenna  55  and controller  66  in the form of MPC 875. A protection circuit  104  is provided for protecting the components from power surge in the telephone line. LEDs are provided to indicate operating states, and a reset switch is provide to reset the device to default operation parameters. A PCMCIA slot  106  is used for programming optional applications of the device. The AGD  14  boards as shown in  FIG. 8  are populated with components similar to those in the PGD  16 , except that it has SLIC  70  instead of the COID  71 .  
       FIGS. 9 and 10  show block diagrams of another embodiment of the Bluetooth enabled PGD  16  and AGD  14 .  
      The PGD  16  and the AGDs  14  have default operation parameters and operation parameters which can be configured by users.  FIG. 11  shows steps in configurating the parameters as shown in the following tables The configuration process may have voice and/or text based prompts for users to enter details.
