A digital set-top box is a receiver that can receive digital broadcasting (satellite, cable, terrestrial). It is a digital multimedia device that receives digital broadcasting (video / audio) signals in the form of compressed IP-based TS stream and transmits them to display devices such as TVs. It is a kind of.

The current broadcasting service transmits video (program) classified by channel, and the set-top box receives and displays it on a TV, and multimedia services such as VOD and MOD using a communication network are also essential for high-speed communication networks such as xDSL. In the case of using a multimedia service using the Internet protocol, there is a serious obstacle in providing a satisfactory service due to the limitation and the load of buffering occurring in the process of downloading content from a server.

In the case of the conventional digital broadcasting receiver, only digital broadcasting is received, and on-demand contents such as VOD and MOD are possible only in the online state. Depending on the number of network users, the screen may be interrupted.There is a limit to buffering when downloading content, and there are time restrictions such as quick viewing and rewinding. Initial buffering time of tens of seconds to several minutes is required at the beginning of use, and high-speed communication network such as ADSL is necessary for service (service cannot be provided in areas where high-speed communication network is not established), and Internet (e-mail) is not possible (satellite set-top box, cable) Set-top box), update application upgrade security module installation and update Bit IP set-top box was only possible under online.

The present invention has been devised to solve the above problems, and is connected to a separate high-speed communication network at the same time receiving digital broadcasting with a DVB-T broadcast receiver, a mass storage device, an IP set-top box, and a backup modem. Even if it is not, the purpose of the present invention is to provide a digital broadcasting receiver capable of stably providing digital contents such as VOD and MOD to users by using digital broadcasting frequency.

The present invention for achieving the above object, the integrated multimedia data received with the digital broadcast to separate the broadcast wave in the broadcast receiving device and display in real time according to a predetermined standard such as EPG on the display device such as TV In addition, digital content data is stored in a high-capacity storage device such as an HDD in a form requiring authentication for use, and the user can review the list if necessary and immediately play or utilize the corresponding content by a predetermined procedure.

To this end, the operating system and application programs must be installed and operated in a flash memory in a broadcast receiving device in the form of an embedded system. Such a system can be automatically updated and upgraded even when a separate communication network is not connected according to the needs of a service provider.

In addition, service users authenticate from service providers when using paid services (contents), send and receive information with service providers when using T-Commerce, and send and receive e-mail (mail), games, chats, and various two-way internet accesses to service providers' servers. In order to use the service, a modem or equivalent network connection device should be attached to the broadcast receiving device and the user can directly control it. In addition, in order to protect the service users in the network online state from malicious access (hacking) from the outside, a security module must be installed in a specific area of the broadcast receiving apparatus, and updates and upgrades thereof can be made online.

Services such as VOD and MOD should provide the service user with software such as pause, fast view, rewind, slow view provided by VCR, DVD player, etc., and the control is controlled by wireless remote controller and keyboard. Can be performed.

The present invention may be generally configured as an external type, and in some cases, may be mounted inside a display device such as a TV or a monitor.

1 is a block diagram showing a digital broadcast receiving apparatus according to the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In one embodiment of the present invention, a DVB tuner for selectively receiving DVB-T broadcasting from a UHF antenna and receiving digital content data as analog data, and digital content transmitted in the form of an analog signal from data transmitted from the DVB tuner. A demux for extracting data, a decoder for converting digital content data in the form of an analog signal extracted from the demux into a digital signal, and outputting the digital signal, a hard disk for storing the digital content data output from the decoder, a digital stored in the hard disk An encoder that converts content data into an analog signal and outputs the same to a display device, a LAN card that enables authentication of digital content data stored in the hard disk through an internet network, and digital content data stored in the hard disk can be authenticated through a PSTN. With It is composed of a modem, DDR memory, the microprocessor, the microprocessor is provided so that the operating program is stored can be connected to the flash DOM, VFD display device can be controlled by remote control or keyboard control panel, a power supply.

DVB-T (Digital Video Broadcasting) is one of Digital-TV's broadcasting standards developed and mainly used and intended to be used in Europe. "T" stands for Terrestrial. In addition, DVB-S (Satellite), DVB-C (Cable), etc. can also be used.

A tuner is mainly used at the input of a radio receiver and tunes to a frequency of a certain radio wave (or electric signal) to select and take out only the radio wave.

Demux (Demux) is composed of crystal oscillator driven by voltage by extracting Program Clock Reference (PCR) value from incoming MPEG-2 transport stream and decomposing several divided digital signals and dividing them individually. .

A digital content provider uses a multiplexer (MUX) to transmit digital content along with a plurality of broadcast data to an output circuit, and divides the digital content received by the tuner in a demux.

A decoder decodes the digitally coded data and converts it into an analog signal corresponding thereto, and an encoder converts the analog data into a digital code that can be calculated and outputs the converted analog code.

The DOM flash is stored in the DOM by the operating program of the microprocessor. The DOM is a programming interface that connects HTML and XML documents. It can provide a standard programming interface for use in a variety of environments and applications.

The modem is connected to a public switched telephone network (PSTN), and supports the function of a LAN card to transmit and receive authentication signals of digital content.

Digital data that does not require authentication is immediately available without access to the internet network, and only when authentication is required, the digital data is accessed through the LAN card and modem.

The hard disk stores the digital content data output from the decoder and outputs the digital content data in response to a user's call signal.

The control panel is provided to connect a display device such as a VFD (Vacuum Fluorescent Display), can be controlled by a remote controller or a keyboard, and uses SMPS as a power supply unit.

As described above, according to the digital broadcasting receiver according to the present invention, it is possible to simultaneously receive digital broadcasting, digital content, and digital data not only online but also offline, and maintain high quality and stable service quality without generating any server load. In addition, after authentication of the paid service is completed, the service is performed in the offline state, so it is possible to maintain high quality and stable service quality, and there is no time limit because there is no buffering since digital content is stored on the hard disk. Not only can it be used immediately, but it can also be serviced by a modem alone (services can be provided in the area where the phone is installed), update application upgrade security module installation, and update both online and offline.
