Description

Digital satellite receiver which has software copying in function}

The present invention relates to copying and downloading of software and channel data in a digital satellite broadcasting receiver. In particular, the present invention relates to a digital satellite broadcasting receiver without using a separate device. Of course, the present invention relates to a digital satellite broadcasting receiver having a function of copying or downloading up to channel data.

The satellite broadcasting receiver is configured to receive broadcast signals from satellites (communication satellites) located at altitudes of several hundreds to tens of thousands of kilometers on the earth's surface.

The satellite broadcast receiver also receives an additional degree for the received broadcast signals when receiving a broadcast signal for each channel transmitted from the satellite.

A general satellite broadcasting receiver selects an antenna receiving a satellite broadcasting signal transmitted from a broadcasting satellite and a channel selected by a user from the satellite broadcasting signal received from the antenna, and amplifies the intermediate frequency amplification, analog to digital conversion, and applies the demodulated signal to a demultiplexer. Depacketizing the desired packet table among PID (Packet ID) information of the digital satellite broadcasting signal applied from the channel unit and the channel unit, and in the case of the paid pro, the scrambled broadcast signal is descrambled. The descrambler descrambles and reapplies the demultiplexer and the depacketized broadcast signal in the demultiplexer to decompress the video signal to the PAL / NTSC encoder and the audio signal to the audio D / A converter. MPEG A / V decoders and digital rooms decompressed by the MPEG A / V decoders It consists of a PAL / NTSC encoder that outputs video signals to a TV monitor during transmission calls, an audio A / V converter that processes audio signals and outputs them to a speaker, and a remote controller that wirelessly controls all operations of the satellite broadcasting receiver.

To download channel data to the satellite broadcasting receiver having the above configuration, purchase or manufacture a device (laptop, desktop PC, JIG, etc.) that can be separately downloaded. It has been a disadvantage and a limitation to download (download).

An object of the present invention is to solve the inconvenience of the prior art as described above, anytime, anywhere without using a separate device (laptop, desktop PC, JIG, etc.) Channel Data (Channel Data) and software It is to use Software Upgrade conveniently.

In addition, if the user wants to have all the environments already obtained using the digital satellite broadcasting receiver, that is, the same channel data, the frequency, symbol rate, forward error correction, polarity, and channel of the satellite Without the hassle of separately manipulating and setting up information such as channels, the user can obtain a product in the same environment with only a cable.

Another object of the present invention is to allow users to easily select upgrades, programs, and copies of channel data, etc., without the need for a separate device in a convenient place such as home or office. It is to allow download.

A feature of the present invention for achieving the above objects is that the existing satellite broadcast receiver can be more conveniently downloaded (Main Software) or channel copy (Channel Copy), such as a digital satellite broadcast receiver In the memory, a user table that inputs information such as satellite frequency, symbol rate, forward error correction (FEC), polarity, and channel, which are separately set by the user, and a table containing various information given by the product. And a table for automatically scanning each channel according to the satellite information on the frequency table corresponding to the satellite for the selected satellite, and a table for downloading the stored channel and various information.

Hereinafter, with reference to the accompanying drawings will be described embodiments and configurations and operations according to the present invention.

3 is a flowchart illustrating a digital satellite broadcast receiver that enables a software copy function in the digital satellite broadcast receiver according to the present invention.

4 is an internal block diagram of a digital satellite broadcast receiver that enables a software copy function of the present invention.

As shown in FIG. 4, an internal program of a digital satellite broadcasting receiver that enables a software copy function is built in a separate program that allows a user to download a desired program. Communication interface unit 12 capable of downloading when desired, CPU 10 which is a central processing unit capable of controlling or processing all signals, and EEPROM which stores editable data ( 4) a RAM (5) for storing data for operation, a flash memory (6) for storing a program for actual operation, and a driving circuit (11) for driving signals of the respective parts. , RF module (9) that accepts signals so that the user can perform the desired function, FND (7) that displays the current time and operating channel, Fron that can be used as function selection and operation keys t Key (8).

According to an embodiment of the present invention, a software download and a channel data copy can be performed in a digital satellite broadcast receiver. First, a copy is made through a monitor screen in a digital satellite broadcast receiver serving as a source. When the menu is selected on the On-Screen Display (OSD) screen with the (Copy) command, the microprocessor receives this signal and enters various information tables (Channel Datat, Main) that are input at the time of product shipment to the Flash Memory. Software (Main Software) and a table containing various information inputted and stored by the user in the EEPROM are targeted by the serial data transmission method of the RS-232 interface type which is an output from the microprocessor. RS-232 interface to other digital satellite broadcast receivers for information on EEPROM and Flash Memory And stores the blood (Copy) and download (Download).

The digital satellite broadcast receiver having the above-described configuration requires only a digital satellite broadcast receiver having this function in place of a bulky equipment or a separate equipment. Channel Data Copy) can be serviced using a serial cable, which increases convenience and time savings.
