Description

RECEIVING SYSTEM OF BROADBAND DATA AND METHOD TO RECEIVE AND TRANSMIT DATA FROM A WIRELESS NETWORK Field of the Invention This invention relates to a data reception system that includes apparatuses and methods for communicating data through a wireless TV connection device (i.e. a decoder) and in particular to using a decoder receiver, for receiving packet signals from a satellite transmission and accompanying means for data transmission to a wireless network, through a cellular network CDPD (cellular digital packet data). BACKGROUND OF THE INVENTION Decoders are generally designed to receive TV signals by broadband means such as satellite transmissions and cable connections. Due to the wide bandwidth of TV signals, decoders such as Direct * 48 have the ability to receive data at high transmission rates. This capacity is not substantially used in other applications due to the singular application regarding TV reception granted to the decoders. These applications use TV-specific data compression techniques specifically aimed at TV transmission and therefore the transmission of data per se is not normally considered as an application for the decoder. REF: 25370 Compendium of the invention Termination equipment for a wireless network WorldNetHR receives data in ATM packets (asynchronous transfer mode) from a data terminal of a Direct TV1 decoder **. These are addressed to a recipient through a first power port of a directionally responsive router (i.e. a packet address is controlled within a router to be from an input port to an output port regardless of the address of the spindle (and transmits over a coaxial or wireless LAN subsequent to the data equipment in the customer's premises) Responses to the network by the equipment in the customer premises are transmitted over coaxial or wireless LAN to the directionally responsive router and then from the router to a CDPD radio modem for transmission, through the cellular CDPD, to a remote wireless termination connected to the wireless network Brief Description of the Drawing The only figure is a block diagram of a transceiver / data processing scheme for receiving data through a Direct TV decoder "8, connect it to a wireless LAN, and transmit data from output from the LAN as CDPD transmission.

Detailed Description A system for wireless network access WarldNet "*, as illustrated in the figure, includes a dish antenna 101 for reception of broadband data and TV signals from a satellite transmitter or microwave transmitter, for example It is connected by coaxial cable (RG-6) 102 to a Direct TV decoder *** 103 that is primarily designed to receive compressed TV signals and decompress and apply them, using a coaxial cable (RG-6) to a TV set 106. (TV sets and decoders are consumer items are readily available and do not need to be described here.) Decoder 103 has a broadband capability to handle television signals and in many cases the device has an output port of Non-TV data is primarily a receiving device and does not normally transmit signals, signals are received primarily from the satellite dish antenna 101. normally received signals are compressed TV signals that subsequently decompress to see. Data signals are extracted before any decompression processing. The present decoder includes a data port 107 which is connected by a cable 109 to a power port 110 of a WorldNet data port14 111.

The WorldNet14 data port * 111 includes a Direct TV decoder interface * 121 connected to the ultimating cable 109 through its input port 110. This interface can be designed in accordance with the operational descriptions that are provided upon request by Hughes Corp. The output of the interface 121 is connected to a directionally responsive data processor / router 125. Addresser 125 reads packet header address information and uses this information to determine a last address for the packet. The identity of the receiver port of the router determines the output of the packet's own address. Your final address after router output is determined by the packet header that directs the packet to its intended destination after leaving the router. The address 125 is responsive to address that has control algorithms to direct packets from a particular feed to a particular output of the router. Last or final packet destinations are of course controlled by packet header address. Packets received by the router from interface 121 are routed to the PC-MCIA LAN radio broad band 135 packets. Returned packets of the PC-MCIA LAN 135 are routed by the router 125 to a CDPD modem 141. While this operates from different way from the traditional router where packet directionality is based only on the spindle direction, its design will be easily apparent to those with skill in the specialty. An EtherNef01 processing station 126 also connects to the router 125, connects to a cable TV modem 127 that receives TV signals or data information, via the coaxial cable (RG-6) 129. Under appropriate circumstances, the EtherNet processing station ** can be a LAN station that allows the transmission of data to the LAN. This processor is commercially provided by Motorola commercially identified as MC 68360. As illustrated the output cable 123 can be connected to a wired PC. The router 125 can also directly connect the EtherNet14 * station to a radio moderator 141 to locate the sources of CDPD transmissions. The router 125 of the radio port 111 is connected by PC-MCIA connector devices (Personal Computer Memory Card Industry Association) 131, to a LAN PC-MCIA radio broadband packets 135. PC-MCIA is a commercially available connection card that includes a radio transceiver and a quarter-wave vertical antenna 136 for RF transmission and reception. Therefore, packets can be sent by radio and received as an RF radio signal. The router 125 is capable of handling received packets at a certain power and sending them to a power dependent output, due to directional sensitivity controlled by power from the directioners. Wireless packets from the LAN, received by antenna 136 and radio pack 135 are coupled to a PC-MCIA 141 radio modem as discussed below. This packet radio unit 135 communicates through an antenna 136 to provide packet radio transmission and reception to and from a wireless LAN. The unit 135 also includes a cable connection 137 for wired access to the LANs connected by cable. The radio port 111 is also connected through the router 125 to the radio modem 141 which is a PC-MCIA card containing a CDPD radio modem to communicate, by means of a quarter-wave vertical antenna 142 with a packet network wireless CDPD (Digital Cellular Packet Data = Data of Digital Cellular Packet). CDPD is a commercially available service and is well known to those with expertise in the specialty. Its primary value is as a backup channel for travel on the Internet where the downlink is for the Direct TVHR service. This unit also provides the ability for the LAN to communicate out of the LAN with other data systems through router 125 and CDPD modem 141 to a CDPD wireless network.

It receives its data packets for transmission directly from router 125 through terminal 147 and sends them by radio transmission (ie, cellular transmission) to a cellular CDPD wireless system via its output antenna 142. A state panel 151 is connected to allows verification of the operational status of the router 125. A power supply 155 is used to power the interfaces and router. It can work through AC-to-DC conversion is from one or certain power output. instances comprises a battery pack. An optional Printed Wiring Board (PWB = Printed Wiring Board) 161 can be included in the data processing system and is used to control communications between a user and the TV and decoder. An example is the use of an aerial mouse 149, which communicates with PWB and by an infrared signal. This can be used to control the cursor on the TV screen. This PWB is incorporated technically similar to a visualization circuit for network TV services and is well understood by those with skill in the specialty. This PWB includes a 10 PC on a card 162, a memory 163 and an NTSC interface (ie National Television Standards Committee = Committee of National Television Standards) 164 which interconnects with the TV 106 and the Direct TV * 5 * decoder. This allows various data / audio transfer between the decoder 107 and TV 106 and / or equipment in stereo. Schematic 175 illustrates a possible physical size relationship of the data port and decoder. It is noted that in relation to this date, the best method known to the applicant to carry out the aforementioned invention, is that which is clear from the present description of the invention. Having described the invention as above, property is claimed as contained in the following:
