TERRESTRIAL DIGITAL BROADCAST WAVE MONITORING APPARATUS |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a terrestrial digital broadcast wave monitoring apparatus capable of more efficiently performing high-quality monitoring of terrestrial digital wave broadcast of an OFDM (orthogonal frequency division multiplexing) modulation type by remote monitoring. <P>SOLUTION: An image generation part 18 processes constellation data having a transfer rate set to about 80Mbps and to be outputted by an OFDM demodulation part 16 to thereby generate a constellation image of a binary image of which the image size is set to 256 bit (X axis) × 256 bit (Y axis)= 65K bit and the whole or a part of the generated constellation image is transferred to a host PC1 for monitoring. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
