Embodiment Construction

[0035] The present invention will be explained in detail with reference to the drawings. The same reference numerals in the drawings refer to the same components.

[0036] image 3 It is an exemplary block diagram showing a digital multimedia transmitter for transmitting a digital multimedia signal in which identification information is inserted.

[0037]The transmitter with identification information inserted into the digital multimedia signal to be transmitted includes: a scrambler 310, used to scramble the MPEG stream; an FEC (forward error correction) unit 320, used to scramble the slave The signal output by 310 performs forward error correction; the modulation / IDFT (Inverse Discrete Fourier Transform) unit 330 is used to modulate or inverse discrete Fourier transform the signal output from the FEC unit 320; the PN sequence insertion unit 340 is used to convert PN The sequence is inserted into the header of the data frame of the signal output from the modulation / IDFT unit 330...

Abstract

The digital multimedia signal receiver to treat single / multi-carrier mode comprises: a high-frequency head to receive modulated digital multimedia signal; a ADC to convert the signal from high-frequency head into digital format; a pattern detector to detect the signal from ADC is multi-carrier or single-carrier according to information in the signal; and a demodulation unit to demodulate the digital single / multi-carrier signal from ADC according to recognition information from pattern detector contained PN sequence or / and at least a pilot frequency.

Description

Technical field [0001] The invention relates to a digital multimedia receiver and a digital multimedia receiving method, in particular to a digital multimedia receiver for processing multi-carrier modulated digital multimedia signals and single-carrier modulated digital multimedia signals and a digital multimedia receiving method thereof. 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, different standards have been proposed for digital broadcasting in various countries. [0003] On December 24, 1996, the United States Federal Communications Commission (FCC) proposed the Advanced Television System Committee (ATSC) digital television standard as the next-generation tele...
