Abstract

The digital multimedia signal receiver to treat single / multi-carrier mode comprises: a ADC to convert the signal from tuner into digital format; a controller to detect the modulation mode for digital signal; a single / multi-carrier signal treatment unit. Wherein, the controller detects at least one reference signal from single / multi-carrier treatment units to determine the modulation mode, and receive MPEG flow from single / multi-carrier unit to output for single / multi-carrier modulation mode.

Description

technical field [0001] The invention relates to a digital multimedia signal receiver and its receiving method. More particularly, the present invention relates to a digital multimedia signal receiver for processing single-carrier modulated signals and multi-carrier modulated signals, which can automatically process single-carrier modulated signals and multi-carrier modulated signals according to the modulation mode of the received signal One of the modulating signals. Background technique [0002] In the era of multimedia communication and broadcasting, countries around the world are digitizing analog broadcasting. Especially in developed countries like the United States, Europe, and Japan, digital broadcasting systems have been developed and put into practical use. According to such rapid development, in various countries, different standards have been proposed for digital broadcasting. [0003] On December 24, 1996, the US Federal Communications...
