Description

Portable DMB reception device

The present invention connects a DMB receiver to a portable terminal that cannot receive a DMB signal through a connection terminal such as a USB to enable viewing and listening to DMB broadcasts using video and audio data received from the DMB receiver. The present invention relates to a portable DM receiver.

In modern society, mobile communication terminals (ie, mobile terminals) are widely used as necessities for modern people as a means of convenient communication regardless of place. However, recent portable terminals provide various functions in addition to the conventional mobile communication service as the performance of the processor is improved and the resources of the memory are increased.

Recently, DMB technology has been developed and commercialized so that it can be miniaturized to meet the high penetration rate of the computer, the current situation of digitalization, and the Internet, and enable digital multimedia broadcasting and digital audio broadcasting between mobiles. It is a digital multimedia broadcasting that can provide CD quality sound and data or video service, and provide high quality fixed and mobile reception.

In general, DMB service currently being serviced is capable of receiving various high quality contents and broadcasting services on the go by receiving digitized signals through various types of portable terminals available to consumers. The DMB service capable of such a digital multimedia broadcasting service is capable of various types of data services, and is expected to generate high added value in various fields such as various multimedia technologies, communication transmission technologies, and DMB related terminal fields with the development of the DMB service.

Here, DMB is classified into terrestrial DMB and satellite DMB according to data transmission means. Terrestrial DMB uses only the network of the terrestrial network and uses frequencies corresponding to 174-216 MHz (42 MHz). This frequency range corresponds to over-the-air TV channels 7-13. Using this frequency domain, 18 CD-level audio channels can be obtained at a frequency of 6 MHz corresponding to one TV channel.

Satellite DMB will provide services using satellite networks and Gap Fillers. Satellite DMB uses frequencies from 2,605 to 2,655 MHz (50 MHz). It is possible to provide 10 or more video channels using this frequency domain.
