Abstract

Disclosed is a satellite digital multimedia broadcasting (DMB) receiving apparatus and method for tracking the position of a satellite and displaying the satellite's position on a terminal. Additionally, in the presence of an obstacle, notifying a user of a reception impossible state caused by the obstacle, in order to enable the user to efficiently receive a satellite signal. The terminal for receiving digital broadcasting included a receiver for receiving a digital broadcasting signal, a geo-magnetic sensor for determining the position of the terminal, a controller for generating broadcasting reception state information using the azimuth of a satellite and the position of the terminal, and a display for displaying the broadcasting reception state information.

Description

technical field [0001] The present invention generally relates to a device and method for receiving satellite digital multimedia broadcasting (DMB), and, in particular, relates to a satellite DMB receiving device and method for tracking satellite positions and displaying satellite positions on a terminal, in addition It also relates to, when interference occurs, notifying the user of a reception impossible state caused by the interference, so that the user can effectively receive satellite signals. Background technique [0002] Compared with the analog broadcasting service, the digital broadcasting service (that is, generally called digital broadcasting) provides a better service with high image quality and higher sound quality. Therefore, the digital broadcasting service can be regarded as a substitute for the analog broadcasting service. The development of digital broadcasting technology and mobile communication technology has recently aroused interest in digital broadcas...
