COMPLEX TYPE DMB RECEIVER CONNECTED DIRECTLY

TO THE INTERNET

Technical Field

[1] The present invention relates to a complex type digital multimedia broadcasting

(DMB) receiver connected directly to the Internet, more particularly to a complex type digital multimedia broadcasting (DMB) receiver connected directly to the Internet that can save or display all sorts of moving images through the direct connection to the Internet by integrally or separately forming TCP/IP chipsets in a main processor, by enabling the DMB receiver to perform functions of a small-sized computer, including a multimedia function. Background Art

[2] A digital multimedia broadcasting (DMB) is mobile multimedia broadcasting for enabling a user to enjoy high quality of audio (radio) and picture service (TV) while moving around. The DMB is promoted for the digitalization of radio, which could supply moving image services, because it was possible to process audio at a speed of 380kbps and additional data and more.

[3] A TV receiver has been mounted in several of the conventional cars. However, there are problems that the TV receiver made some noise or its connection was cut off, due to low reception ratio of a radio wave. Now, in order to solve the problem, digital multimedia broadcasting, a sort of mobile TV is commercially promoted. The currently broadcasted DMB enables a user watch high definition broadcasting without broken connection, hereafter, it enables the user to watch DMB with a mobile phone according to the development of technology.

[4] Digital multimedia broadcasting is largely divided into a satellite digital multimedia broadcasting and a terrestrial multimedia broadcasting. The terrestrial multimedia broadcasting enables a user to watch broadcasting by catching the radio wave emitted from a transmitting station as a general TV, and the satellite multimedia broadcasting by means of distributing the radio wave all over the country through a satellite.

[5] The terrestrial digital multimedia broadcasting, capable of transmitting various contents such as music, short messages, moving images and the like through a portable terminal such as a small-sized TV and a PDA in virtue of an outstanding mobile receiving property, may construct a complementary connection with the terrestrial digital TV broadcasting and then create the epochal demand through a service joined with a mobile communication terminal.

[6] The satellite digital multimedia broadcasting, capable of supplying multimedia broadcasting services including audios, additional data or moving images to a fixed receiver, a mobile receiver or portable receiver through a satellite, may supply audio broadcasting services in various quality at low cost and epochally extend a service range of the conventional broadcasting by covering a wide region by using a satellite.

[7] The difference between the terrestrial digital multimedia broadcasting and satellite digital multimedia broadcasting is the same as that of general TV broadcasting and satellite TV broadcasting. In other words, the terrestrial digital multimedia broadcasting enables a user to watch broadcasting for nothing, however, the satellite digital multimedia broadcasting enables a user to be ready to suffer from subscription fee to what extent due to satellite rental fee. In addition, the satellite digital multimedia broadcasting having scores of channels is distinguished from the terrestrial digital multimedia broadcasting having a few of channels in comparison with the satellite digital multimedia broadcasting which are currently broadcasted, and predicted to increase in number of channels.

[8] According to the technological progress, it enables a user to enjoy high definition broadcasting on a HD TV at home and watch digital multimedia broadcasting while moving around, in other words, when the user drives a car or watches broadcasting with a mobile phone or a PDA.

[9] FIG. 1 is a conceptual diagram illustrating a general digital broadcasting.

[10] Referring to FIG. 1, satellite broadcasting is emitting a video/audio signal and the like manufactured by a broadcasting station through a transmission/reception earth station and transmitting a signal to a reception earth station at a distant place using a satellite which is a geostationary satellite as a repeater, so that the signal is transmitted to a satellite for digital broadcasting from a terrestrial digital broadcasting earth station, and the transmitted signal is received from the satellite and downstreamed through a S- band ranging from 2 to 4 GHz. On the other hand, terrestrial broadcasting is transmitting a video/audio signal and the like manufactured by a broadcasting station to a repeater and the transmitted video signal and the like is downstreamed through UHF or VHF, or L-band. The above digital broadcasting signal received to a mobile and a fixed digital broadcasting receiver enables a user to watch various moving images.

[11] Now, a terrestrial DMB receiver serviced within the country may supply services for a PMP function of storing a series of MPEG-4 moving images, a MP3 function, an electronic dictionary function, a digital camera function and so on, compositively.

[12] According to technologies now in progress or manufactured technologies, it has not been realized that a receiving module for receiving digital multimedia broadcasting is directly connected to the Internet, so as to connect to a specific site for education or provide various moving image contents.

[32] The antenna 110 receives a predetermined digital broadcasting signal transmitted from a satellite or a ground station and a carrier wave signal including general data information, and then transmits the signals to the front end unit 120. Further, in case of terrestrial digital multimedia broadcasting, the antenna 110 receives a predetermined digital broadcasting signal transmitted from a terrestrial wave transmitter and transmits the signal to the front end unit 120 to be described below.

[33] The front end unit 120 received with the digital broadcasting signal from the antenna 110 selects a channel in a specific frequency band according to a control signal of the main processor 140 to be described below. Further, the front end unit 120 outputs and transmits only signals of a base band to the decoder 130 by performing filtering on the digital broadcasting signal transmitted through the selected channel.

[34] The decoder 130 received with the digital broadcasting signal of the base band from the front end unit 120 performs demodulation on the signal into a desired digital broadcasting signal according to a control signal of the main processor 140 to be described below, and separates the demodulated signal into picture data (audio data and video data) and all sorts of additional data.

[35] The separated audio data, video data and all sorts of additional data are decoded by a predetermined decoder included in the decoder 130 and then transmitted to the main processor 140 to be described below. The audio data corresponding to the additional data are outputted through a speaker 180.

[36] The main processor 140 that received the digital picture data decoded by the decoder 130 outputs decoded data and displays the data to a display unit (not shown) through the display interface 170, so as to enable a user to watch digital broadcasting in real time, or to encode the decoded digital picture data into MPEG-4 format and then output the data to the memory 190.

As such, the decoded data in relation to the outputted moving image are displayed to the display unit through the display interface 170, and audio data are outputted through the speaker 180.

[39] In other words, the input data decoded by the main processor 140 are data stored in the memory 190 or Internet communication data inputted through the TCP/IP processor 150. The decoded data are outputted to the display unit through the display interface 170.
