Recently, in accordance with the rapidly developing digitalization trend, TV broadcasting standardization work is in full swing, and some of them have started specific services, especially HD-DIVINE at IBC (international broadcasting convention), the largest broadcasting competition in Europe. Since terrestrial digital HDTV broadcasting called high definition-digital video narrow-band emission has been introduced, projects related to digital TV broadcasting by country and region have been in progress.

The digital broadcasting has been required to develop digital television that satisfies these stringent requirements by providing improved image quality and sound quality compared to analog broadcasting currently provided.

Therefore, in preparation for digital broadcasting, many companies are developing a system software upgrade method for receiving digital broadcasting and data broadcasting on a conventional TV.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The present invention is not limited to the embodiments set forth below, and the invention modified by the addition, limitation, deletion, addition, etc. of components within the scope obvious to those skilled in the art to which the present invention pertains may be presented. There will be.

2 is a block diagram illustrating components for upgrading a TV system software according to the present invention.

The components for upgrading the system software of the TV include a TV manufacturer 210 that holds upgrade information for the TV, a cable broadcasting station 200 that transmits the upgrade information to a user's TV, and a home TV ( 300) and a cable connected to the TV in the home from the cable station 200.

The TV 300 receives the TV system software upgrade information data broadcast transmitted from the cable broadcasting station 200 and receives the latest system software through the cable 220 and the inside of the TV 300. CPU 330 for controlling and adjusting various devices and functions, a display unit 340 for outputting a TV signal through a display module, a flash ROM 350 that is an internal TV memory, and an internal portion of the CPU 330. SDRAM 320 to support the operation.

In more detail, the receiver 310 includes a tuner (311) and a demodulator (312).

The tuner 311 is mainly used in an input unit of a radio receiver, and tunes to a frequency of a fixed radio wave (or electric signal) to select only the radio wave and is also called a tuner. It is a device combining a proper coil and a condenser. In general, one or both of the coil and the capacitor are variable, or the combination can be changed so that many frequencies can be tuned.

For example, radio receivers use a barricon (variable capacitor) to enable reception over the entire broadcast frequency band. In the case of a television receiver, the tuner 311 is formed by integrating the antenna input unit to the intermediate frequency conversion unit to form a sufficient electrical shield. In general, the tuner 311 is often used for television rather than radio.

A demodulator 312 performs an operation of restoring a signal received in data communication to an original signal. In communication, a modulated wave changed according to a signal such as an image or a voice is transmitted to a high frequency (carrier) as a fundamental wave, and a receiver extracts the modulated wave from a high frequency current and restores the original signal. This is called demodulation.

The demodulation method varies depending on the modulation method. In the case of amplitude modulation, rectification or other nonlinear circuits are used. In the case of frequency modulation or phase modulation, demodulation is performed by combining a frequency discriminator and a demodulator 312 during amplitude modulation.

For example, to transmit a digital signal processed by a computer to an analog transmission line such as a telephone line, convert (modulate) the analog signal to be handled by the telecommunication network, and transmit it to the receiving computer to recover the original digital signal. (Demodulation) is required. Devices that play this role are called modulators, or modems.

The CPU 330 is composed of an arithmetic logic unit that is responsible for comparison, determination, and operation, and a control unit that is responsible for interpreting and executing instructions. An ALU is an adder that performs various additions and results, an accumulator which is a register that temporarily stores the result of arithmetic and logic operations, and a register that is a kind of temporary storage device in a central processing unit. (register) or the like.

The control device sends a control signal to a program counter that controls the execution order of the program, an instruction register that temporarily stores the contents of the currently executing instruction, and decodes the instructions contained in the instruction register. It consists of an instruction decoder.

The display unit 340 is responsible for outputting an image signal or an audio signal transmitted from the CPU 330 to the outside. Plasma Display Panel (PDP), which is an embodiment of the display unit 340, is a radioactive display that uses light emitted by plasma and phosphor bonding.

The PDP, which realizes a high-precision large screen, is a next-generation image reproduction method that succeeds a CRT or a liquid crystal TV (300), and forms a single screen with a set of fine phosphors. That is, two glass substrates arranged side by side with transparent electrodes are overlapped with a gap of about 0.1 mm, and a thin gas is placed therebetween to apply a voltage to discharge the ultraviolet rays, which emits phosphors. The phosphor has a structure in which three cells of R / G / B (red / green / blue) are divided into partitions, and light emission of the phosphor enables reproduction of all colors.

In the PDP method, since each cell discharges and phosphor emits light, the PDP method is much thinner than the CRT method, and the viewing angle is about 2.7 times wider than that of the liquid crystal. In particular, 100% full plane is possible, so you can see clear and bright images with no distortion.

SDRAM 320 is a generic name that refers to all of the various types of DRAM whose clock speed is synchronized with the microprocessor. Clock speed synchronization helps to increase the number of instructions that a processor can perform within a given time.

The speed of the SDRAM 320 is expressed in megahertz (MHz) without using nanoseconds, because it is easier to compare the bus speed with the RAM chip speed.

Flash ROM is a non-volatile memory. Even if the memory is not powered, the stored data is not deleted.

In Flash ROM, 'flash' means that the process of writing and erasing data into memory is very convenient. Flash ROM is used in a variety of mobile products, including digital cameras, because it is easier to use, more reliable, faster, larger in capacity and less expensive than other memory types.

Code for operating the CPU 330 can be downloaded to the flash ROM 350, and since a part of the contents can be stored in the memory card, data can be read from the memory card, stored, and output. You can also store options for various users to set.

The operation of the system for upgrading the TV system software having the above configuration is as follows. The TV manufacturing company 210 cooperates with the cable broadcasting station 200 to provide system software upgrade information of each TV, and when the cable broadcasting station 200 broadcasts the provided data through a conventionally installed cable, the TV broadcasting company 210 watches data broadcasting through a television. If the user has the latest system software upgrade information necessary for the TV 300 in the home, the user inputs a reception command through the display unit 340.

When the user selects the latest system software upgrade of the TV 300 by manipulating the display unit 340, the user is connected to the upgrade server 210 of the cable broadcasting station 200.

The latest system software is downloaded from the cable broadcasting server 210 having the TV system upgrade information in association with the home appliance company server 210 and stored in the flash ROM 350 of the TV 300.

In detail, when the latest system software of the TV 300 is downloaded from the cable broadcaster, the CPU 330 inside the TV 300 deletes the existing system software stored in its flash ROM and the system file. Using the Trivial File Transfer Protocol (TFTP), an application protocol used to transmit and receive information, the latest system software is downloaded from the cable broadcaster 240 and temporarily stored in SDRAM (Synchronous DRAM: 320) and then stored in flash ROM. Save to allow system software upgrades.

3 is a flowchart showing a system software upgrade method of a TV according to the present invention.

In the data broadcast of the latest system software upgrade information of the TV 300 through the digital television, the user selects the latest system software upgrade of the TV 300 in the home (S100).

If the latest system software upgrade of the TV 300 is selected in the data broadcast, the latest system software is downloaded from the cable broadcasting station through the receiver 310 (S110).

The latest system software downloaded through the receiver 310 is newly stored in the flash ROM 350 after the conventional system software of the TV 300 is erased, and the TV system software is upgraded under the control of the CPU 330 ( S120).

4 is another embodiment for upgrading the system software of a TV according to the present invention.

The system for upgrading the system software of the TV 300 is characterized by upgrading the TV system by broadcasting and receiving the latest system software upgrade information for the TV 300 using airwaves.

In detail, in order to implement the spirit of the present invention, a TV broadcasting company 220 that delivers the system software of the TV 300 in a broadcast stream and transmits the radio wave, and a TV manufacturing company that provides the latest system software to the TV broadcasting station 300. 210, a TV 300 in the home and a receiver 400 such as a set-top box for receiving the radio waves are required.

The stream transmitted in the broadcast may transmit data information along with the video / audio signal, wherein the latest system software data of the TV 300 is loaded on the data information transmitted along with the video / audio signal. will be.

Looking at the operation of the system for upgrading the system software of the TV 300 having the above configuration as follows.

When the TV station 300 broadcasts the system software upgrade information of each TV 220 through data broadcasting in cooperation with a home appliance company, a user who has been watching data broadcasting through a digital TV needs the latest system necessary for the TV 300 in the home. If there is software upgrade information, the latest system software can be downloaded through the receiver 400.

When the latest system software download of the TV 300 is completed in the radio wave transmitted from the TV station 300 through the receiver 400, the TV 300 stores the existing system software stored in its flash ROM. By using the Trivial File Transfer Protocol (TFTP), which is a protocol for downloading the operating system, the latest system software is temporarily stored in the SDRAM, and then stored in the flash ROM to upgrade the system software of the TV 300. To lose.

As another embodiment for upgrading the system software, a method using satellite can be considered.

Satellite communication is a method of communicating between earth stations and earth stations using satellites in space and mainly providing SHF frequency bands to provide various communication and broadcasting services.

At this time, the function of the communication satellite is similar to that of the relay station in the terrestrial microwave communication, and takes the function of receiving a signal emitted from one earth station, amplifying it, and retransmitting it to another earth station.

In the case of terrestrial microwave communication, in order to transmit a long distance, it is inconvenient to establish several repeaters in the middle of the transmission. Therefore, satellite communication is to carry out a communication with a repeater (satellite) in the air.

The path between the transmitting earth station and the receiving earth station through one satellite is called a satellite link, and the signal from the earth station to the satellite is called an up link signal and the signal from the satellite to the earth station is called a down link signal.

In this case, the frequency of the uplink signal is higher than the frequency of the downlink signal. This is because the higher the frequency, the greater the propagation loss in free space, and various reinforcement methods to compensate for this loss can be done more easily at earth stations than at satellites.

Currently, the most widely used frequency bands in satellite communications are 4-8GHz (C band) and 12.5GHz-18GHz (Ku band), and efforts are being made to enhance the performance of satellite communications using Ka band, which is higher frequency.

The advantage of satellite communication is that it can use a large bandwidth for large capacity communication, low communication cost, and improved line quality.

In detail, the communication speed is about 1Mbps upward and 2Mbps downward. This is comparable to the speed of high speed internet service using existing wires. However, because of the use of satellite communication, there are no disadvantages of existing high speed internet services such as speed drop or disconnection caused by the increase of users. Therefore, there is an advantage that can provide a large amount of video services stably.

If only a set-top box or a receiver 400 capable of receiving the satellite signal is provided, the receiver 400 can be connected to the TV 300 to easily receive and install TV system software transmitted from a broadcasting station.

According to the present invention, when a broadcasting station transmits TV system software upgrade data, the system software upgrade information for the TV can be conveniently upgraded by receiving the TV system software upgrade information through a tuner in a TV and providing the user. have.

In addition, the present invention can be expected to improve the performance of the product and the implementation of additional functions by allowing the user to easily upgrade the system software of the existing TV even if the latest product of the TV is released after purchasing the TV once. It is effective to increase utilization and satisfy consumers' desire for the latest TV.
