Embodiment Construction

[0046] An embodiment of the TV receiving system according to the present invention will be described with reference to the accompanying drawings. It is assumed that the TV receiving system is used to receive digital TV broadcast signals. The digital television broadcasting service can be used to transmit the signals of several broadcast programs by multiplexing on a common carrier. It is therefore assumed here that the digital television broadcast receiving system to be described now is adapted to receive and demodulate signals of a plurality of broadcast programs multiplexed onto a single carrier in order to extract and utilize signals of a desired broadcast program.

[0047] figure 1 is a block diagram showing the configuration of a television broadcast receiving system (hereinafter simply referred to as "receiver") embodying the present invention. Referring to this figure, satellite broadcast waves in the 12 GHz band received by the receiving antenna 1 are frequency-conver...

Abstract

A television receiver apparatus has large versatility to adapt itself to newly offered services or new modes of use. An external memory element loaded with a flash memory is connected to the receiver apparatus through an external memory interface having a connector and an interface circuit. The external memory element stores information such as a program for implementing an additional function or data such as video and audio data. The information stored in the external memory element is taken up by the receiver apparatus through the external memory interface. The information from the external memory element is processed by a controlling portion of the receiver apparatus so as to be subjected to use.

Description

technical field [0001] The present invention relates to a television broadcast receiving system for receiving television broadcast signals such as digital satellite broadcast services. Background technique [0002] In recent years, in addition to conventional broadcasting services relying on ground waves, there are broadcasting services using new broadcasting systems such as analog and digital broadcasting systems using geostationary satellites, and their applications are expanding. [0003] For example, a geostationary satellite digital broadcasting system employs a digital compression technique such as MPEG in order to compress data of a plurality of television broadcast programs and transmit the compressed data of a plurality of programs by multiplexing the data on a single carrier, Therefore, television broadcasting services are provided in a manner different from conventional television broadcasting services using terrestrial waves. [0004] By inserting digital data i...
