Set-top box as a signal source unit consumer digital television issues of digital TV transformation program ------ hotels and hospitals to solve the way with the development of global digital TV, China's digital television also followed the trend, according to the State Administration of Radio, arrangement, China is now a lot of cities are making digital TV overall translation work, also known as digital set-top boxes, radio and television departments in most cities are complimentary to every household in a set-top box, and then as a method to improve the subscription fees to digital TV overall translation work, but so that there is a problem: a TV set-top box can be equipped with a normal watch, while some have multiple TVs collective users, will have to pay a high rating fee. For example: a hotel has 100 television sets shall be equipped with 100 set-top box for each charge 25 yuan per month, one-year subscription is $ 300, then the 100 set-top box subscription is 30,000 yuan a year, 5 years The license fee is cumulative 150,000 150,000 for any one unit it is not a small number; in addition, there is a set-top box remote control, the TV has a remote control, two remote controls put together is not easy to use ; set-top boxes in some places when power is turned on there is a boot menu screen, you must enter the menu can normally watch TV, it is also very easy to use; after adding hundreds of set-top boxes, fault repair work increases, problems to get into set-top boxes house investigation, the increased workload engineering staff, affecting the hotel's service image; such as hotel rooms or require a temporary increase in TV set-top boxes must then apply for assembly, otherwise it can not watch; if hotels want to open self-management programs or satellite programs can not realization; the hotel each room add a set-top box and a viewing card for fixed assets custody and administration of daily rounds waiter also brought a lot of inconvenience and even dangerous set-top box fee card was taken away guests or replacement. In view of the above situations and problems, we re-launched with a digital set-top boxes Trondheim as a headend system signal source of value solutions, completely solve your subscription heavy burden high, and this program is easy to solve all these problems (self-management programs for existing satellite units, reusing can be done to eliminate waste), the original wiring network does not need to make any changes, too, as the number of television sets can be unlimited expansion, unlimited . This set of solutions used equipment: trunk amplifier, centralized distributor, set-top boxes, adjacent channel modulator, a signal mixer, standard cabinets, the specific situation is: a digital cable TV signal is first sent by the trunk amplifier, and then transmitted to a centralized distributor, the distributor this way TV signal into a number of signals, and then were transferred to a number of set-top boxes, set-top boxes to cable signals demodulated output audio and video signals, and then transmitted to the adjacent channel modulator, o frequency modulator and then modulate the audio and video signals to a radio frequency signal transmitted to the signal mixer, RF signal after mixing again after a zoom, the final output of the unit to the existing cable television network to, for direct TV watching, without set-top boxes, as the number of television sets can be infinitely expanded, not restricted. In this system, a set-top box and a modulator corresponding to a television program, the number of decisions by the amount of equipment used in television shows, regardless of the number of television, which is the same in the case of investment in equipment, TV The greater the number, the more money. We were still on top of the hotel for example: there are 100 TV sets, set-top box 100 originally required, calculated in accordance with the transmission now we assume that 40 sets of television programs, to every room to watch, only need to use the set-top box 40, You can save up to 60 set-top box out, which is at least a year subscription to the hotel to save 18,000 yuan, five years down the subscription can save 90,000 yuan; the same token, if the hotel has 150 TV sets, 50 sets of programs transmitted in accordance with terms, You can save 100 set-top box, a year subscription of at least 30,000 yuan to save the hotel, five years down the subscription can save 150,000 yuan. The purchase modulator devices such investment only with respect to saving more than a year subscription only; the actual use of set-top boxes from cable television distribution, and asked him to pay the actual number of subscription fees. The system and the equipment used to meet national laws and regulations in force, does not violate the legal provisions in force.
