It is a configuration of the satellite broadcasting receiver 10 system consisting of a central processing unit (CPU) 17 to be connected to the display and the motherboard and the sensor for restoring the power supply unit, image and audio.

In addition, the negative ion generating device 30 of the air cleaner is installed on one side of the satellite broadcasting receiver system as a method for purifying air and maximizing product efficiency to consumers.

That is, the two poles of the pole plate is fixed to be fixed, the two poles of the pole plate is configured so that one end is connected to each other so that the anion is generated by the potential action of the negative electrode (-) and positive electrode (+) when applying electricity The generator 30 is comprised.

Looking at the configuration of the satellite broadcasting receiver 10 of the present invention configured as described above are as follows.

First of all, digital broadcasting refers to a case in which the transmission of a broadcast becomes digital, but it means digitization of the whole process from production, transmission, and reception of a broadcast program.

In other words, digital broadcasting is a new transmission method of radio and TV in terms of transmission.

In the conventional analog method, audio and video are converted into a continuously changing electronic signal and transmitted. In the digital method, a binary number, that is, a series of 0's and 1's, is transmitted.

Therefore, it is strong in resilience and easy to encrypt. At the same time, digital signals have the advantage of being stronger and capable of transmitting at less power than analog signals.

It is also possible to use frequency bands not available in analog for terrestrial digital transmission. In addition, a plurality of program services can be transmitted in the same frequency band by a process called video signal compression. Thus, digital broadcasting offers advantages such as ① multi-channelization, ② improved quality video and audio, ③ new services such as widescreen TV, and ④ improved reception (inter-mobile reception, etc.).

On the other hand, widespread digital broadcasting has other properties.

In addition, widespread digitization leads to maximum efficiency of available programs. This makes it easy to organize in response to the rapidly changing broadcasting environment or viewer demand.

In general, digital satellite broadcasting receivers are implemented in various MPEG chip sets, which are different from company to company, and even in chip sets, FAT (Free to Air), CI (Common Interface), CAS (Conditional Access System) and analog functions It is classified as an added receiver.

Therefore, it is realized as one integrated design system including all functions, and the digital part can greatly contribute to the advantages, price, and productivity that can realize various products when implementing a product by designing a board by method.

Only such a design method can easily cope with the ever-changing digital chip set and system method, and can be said to be a design method for realizing transitional products and diversified products.

In order to help understand the above design schemes, a description will be given with reference to FIG.

1 is a main block diagram of the present invention, in which a signal collected by a dish antenna is transmitted to a dish antenna installed on an exterior of a satellite broadcasting receiver, and a frequency converter (LNB: Low Noise Block Down Converter) is provided through a feed horn. The input signal is amplified and frequency converted.

The frequency converter (LNB) converts the received signal of the 11.7 ~ 12GHz band by 10.75GHz down-converted to an L-band signal of 950 ~ 2150MHz.

A tuner (TUNER QPSK) section 13 that selects a desired carrier from the transmitted signals and demodulates it with a demodulator (QPSK) to decode the digital compressed signal, and the original signal from the video and audio compressed signal from the station. When MPEG (MPa) chip parts, which restore video and audio signals, are separated into digital parts and encrypted in digital signals, the corresponding channel packets are descrambled according to the receiver's reception qualification.

In addition, it is an analog switching unit 14 for connecting the separate signals of video and audio for the convenience of the general consumer to the television and audio equipment mounted on the receiver. The transformer type power supply unit 16 is provided.

2 is a motherboard block diagram, the motherboard of which functions to restore the original video and audio signals from the video and audio signals compressed by the broadcasting station.

The motherboard includes a memory unit 21 having a memory function (SDRAM / Flash ROM / EEPROM), a signal unit 23 of a function of separating video and audio signals (AUDIO DAC / CVBS / RGB / RS232), and MPEG The oscillation circuit section (VCXO) 22 of the frequency setting function of the IC is mounted.

When the digital satellite receiver configured as described above is classified into only the digital part, it can be divided into FTA (Free to Air) method, CI (Common Interface) method, CAS (Conditional Access System) method, and can be divided into analog parts. Here, the FTA part can receive a signal transmitted from a broadcasting station directly to a digital receiver. As can be seen from the PCB configuration of Figs. 3 and 3a, the power supply unit, which is an analog part, is provided with a switching connector so that a switching power supply or transformer type power supply unit 16 is installed and a digital part motherboard is installed. will be. It is a product that anyone can receive broadcasts like an analog receiver.

As shown in Figs. 4 and 5, the CI / CAS part cannot be decompressed by the MPEG decoder when the broadcasting and video signals are encrypted, so in this case, the CI / CAS part must have a function of decompressing an externally encrypted signal. A product with this function is a CI / CAS product. Also, in order to solve the encrypted signal, these products have to be inserted into the PCMCIA module.

In order to make this digital product, an analog main board is being manufactured as one board that can be applied to digital products in an integrated manner.

On the other hand, existing digital products are required for continuous after-sales service for receiving digital broadcasting, which is changed due to being manufactured in each product line. If the broadcasting channel is changed in a specific way, the product can be used. There is no difficulty.

The present invention is an improvement of such an unreasonable, and when the product is in progress, the disadvantage of not being able to see a specific channel, as well as A / S can be compensated, and can further implement a multi-system.

In addition, since the difference between analog and digital is determined by the digital chip set as shown in FIG. 2, the present invention can be applied to various chip sets by installing a plurality of connectors 40. Create effective product lines

3 and 3a represent analog parts, and since the digitization itself is received in binary, i.e., 0 and 1, all other signal and power supply units 16 are demodulated and transmitted by demodulating all video and audio signals from the digital chipset. Since the switch 14, the connector 40, and the like are analog, this part can be designed according to the analog method to create a single integrated product.

In other words, if the system is designed and installed on the existing digitized monolithic PCB, the repair cost and the cost of replacing it with a new one will be the same if any part breaks down. Although it was a system configuration, the present invention is to install a plurality of connectors 40 to replace only the motherboard on the analog-type PCB to impose a rapidly changing function additionally.

In addition, the negative side generator 30 is installed on one side of the main board of the receiver.

4 is a representation of a product for digital CI and CAS using a card as another embodiment of the present invention, which will be rapidly changed with the increasing number of encrypted broadcasts and paying more and more in order to commercialize digital in the future. It is an embodiment coping with what is present.

Figure 5 is another embodiment of the present invention, as shown in Figure 3a to the built-in negative ion generating device 30 of the air cleaner for the convenience of the consumer in the satellite broadcasting receiver of the present invention to maintain product value creation and product safety to be.

6 is a schematic diagram of satellite broadcasting reception according to the present invention, which shows a reception process from a satellite to an antenna 11 through a home, and FIG. 7 is a schematic block diagram of satellite broadcasting reception according to the present invention. The process of receiving from the TV to the home TV is represented by a hollow chart.

As such, when power is applied to the negative electrode plate of the negative ion generating device 30 installed inside the satellite broadcasting receiver of the present invention, the pole plate and the periphery of the pole plate are charged to generate a mineral like lightning, and at this time, a large amount of negative ions are generated.

In addition, the generated negative ions are released to the outside of the fuselage of the ion and oxygen generator or air conditioner to generate negative ions in the room. The characteristics of the negative ions accelerate the air-cleaning effect along with the fine dust collection. It supplies oxygen to the room and purifies the air in the room so that fresh air can be contacted.

The negative ion generator 30 is not necessarily limited to satellite broadcasting receivers, but may be applied to home electronic devices such as televisions and VTRs.

In this way, the present invention can integrate various products into one due to the change of satellite broadcasting receiver design system, and even if A / S occurs, it is easy to replace the motherboard, which is a digital part, and it is produced during production. In addition to low power, light weight, productivity improvement, and cost reduction, such as the advantages of minimizing losses, digital broadcasting includes multi-channel, improved high-quality video and audio, and wide-screen TV.
