Abstract

The invention provides a multimedia terminal equipment which can reproduce and output an object broadcasting program irrespective of a providing medium and so forth of the program. The multimedia terminal equipment includes a digital signal processing circuit in the form of a digital signal processor which is programmable to process various kinds of digital broadcasting signals of different formats. A program to be used for processing of an object digital signal is read out from a ROM by a host CPU in response to a selection input from a user and supplied the program to the digital signal processing circuit. In accordance with the program, the digital signal processing circuit processes a digital signal outputted from a traffic controller in response to the selection input of the user.

Description

technical field [0001] The present invention relates to a multimedia terminal device and a digital signal processing method capable of processing broadcast signals provided by various broadcasts, such as television broadcasts using terrestrial waves, satellite broadcasts using geostationary satellites, or cable television broadcasts, so that the broadcast Signals can be exploited. Background technique [0002] In recent years, in addition to analog television broadcasting using terrestrial waves, digital television broadcasting using geostationary satellites, and cable television broadcasting providing television broadcast programs through cables have also become popular. [0003] For example, in digital TV broadcasting using geostationary satellites, data compression techniques such as the MPEG system are used to compress data to generate signals of a plurality of TV broadcast programs, and the signals thus generated are multiplexed on a single carrier to make them Can be ...
