Data broadcast receiver for use with a computer

摘要

Broadcast data inputted from a terminal 1 is decoded by a tuner 10, and audio/video signals and digital data are separated by a demultiplexer 11. The audio/video signals are converted to analog signals by an A/V decoder 16 and outputted from a terminal 4. The digital data stream is reconstructed from a TS (Transport Stream) packet to an IP (Internet Protocol) packet by a packetizer 12, and an IP address allocated to the data receiving device on the broadcast network on the basis of an address conversion table 13a, obtained in advance, is converted to an IP address allocated to a personal computer on the Internet (via the data receiving device). The reconstructed IP packet is outputted to the personal computer through a LAN interface 14 selected by a routing section 13. An accounting control section 17 is provided, if necessary, for accounting control in receiving chargeable data. <IMAGE>
