Embodiment Construction

[0028] Embodiments of the present invention will now be described with reference to the accompanying drawings. For conciseness, well-known functions and constructions will be omitted in the following description.

[0029] Embodiments of the present invention provide a gap-filling transmitter identification device and a method thereof, wherein the gap-filling transmitter inserts the ID information of the gap-filling transmitter into a control channel in an existing frame, and sends the modified frame to a terminal so that the terminal can identify out of the fill-in-the-blank transmitter that has sent the signal.

[0030] FIG. 3 is a block diagram of a gap fill transmitter according to an embodiment of the present invention.

[0031] Referring to Fig. 3, the signal processing in the gap filling transmitter includes demodulation of time division multiplexing TDM (TimeDivision Multiplex) signal and modulation of code division multiplexing CDM (Code Division Multiplex) signal, an...

Abstract

A gap filler for transmitting satellite broadcasting data received from a broadcasting satellite to a mobile receiver in a satellite broadcasting system is provided and method thereof. In the gap filler, a satellite tuner demodulates the received satellite broadcasting signal and outputs the demodulated satellite broadcasting signal, a frame constructer forms frames by modulating the demodulated satellite broadcasting signal, and inserting a gap filler ID into a control channel frame, and a radio processor transmits the frames received from the frame constructer at a radio frequency.

Description

technical field [0001] The present invention generally describes the satellite digital multimedia broadcasting DMB (Digital Multimedia Broadcasting) equipment and method. Apparatuses and methods for identifying multiple gap-filling transmitters are specifically described. Background technique [0002] A typical DMB system is shown in Figure 1. [0003] Referring to FIG. 1 , a base station 200 transmits a multimedia broadcast signal received from a content provider 100 to a broadcast satellite 300 . The broadcast satellite 300 transmits multimedia broadcast information to the terminal 500A as a relay station. That is, the broadcast satellite 300 multiplexes the received multimedia broadcast information using a code division multiplexer CDM (Code Division Multiplex), and directly transmits the CDM signal to the terminal 500A at a frequency of 2.6 GHz. In order to enable terminals such as 500B to receive multimedia broadcast signals in buildings or shielded areas where broad...
