The present invention relates to a DMB (Digital Multimedia Broadcasting) receiver, and more particularly, to install a DM receiver in a mouse of a computer, and to tune to a computer screen according to a click of a mouse. The present invention relates to a DM mouse having a DM receiver for displaying to a user.

In general, DMB is a broadcasting service that provides various multimedia signals such as voice and video to a digitally modulated, fixed or portable / vehicle receiver.

There are two types of DMBs, terrestrial DMBs and satellite DMBs. The terrestrial wave DMB transmits a program using a frequency on the ground. Therefore, use VHF channel 12 which is currently empty and channel 8 which is for military use. Unlike satellite DMBs, broadcast signals are transmitted through base stations on the ground. The satellite DMB uses a satellite, and when a program is transmitted from the satellite DMB broadcasting center to the satellite, the satellite spreads it to the DMB terminals throughout the country.

The DMB is based on DAB (Digital Audio Broadcasting), a technology for digital radio, and a multimedia broadcasting concept has been added to it to send additional data such as video, weather, news, and location. On the go, you can enjoy CD and DVD-quality high-quality and high-definition broadcasting through your personal mobile terminal or car terminal.
