Digital TV Solutions for Small Hotels

Scheme 1: Principle analysis: Foreign-related hotels can choose satellite signal plus set-top box signal as the signal source solution of cable TV front-end system, and most programs in this scheme can be directly received through free satellites. The equipment used in this scheme includes: satellite receiver, digital TV set-top box, distributor, power divider, antenna amplifier, amplifier, adjacent frequency modulator, mixer, standard cabinet and so on. Specifically, satellite programs are sent to a power divider through a satellite receiving antenna and an antenna amplifier. The power divider divides a satellite signal into several signals, and then transmits them to several satellite receivers respectively. The satellite receivers demodulate the satellite signals, output audio and video signals, and then transmit them to adjacent frequency modulators. The digital cable TV signal sent by the TV station for encrypting TV programs first passes through the signal distributor, which divides the TV signal into several channels and then transmits them to several digital TV set-top boxes respectively. The digital TV set-top box demodulates the wired signals respectively, outputs audio and video signals, and then transmits them to the adjacent frequency modulator, which modulates these audio and video signals into radio frequency signals and transmits them to the signal mixer. The mixed RF signal is amplified again and finally output to the original cable TV network of our unit for TV to watch directly without digital TV set-top box. As for the number of TV sets, it can be expanded indefinitely.

Scheme 2: Principle analysis:

Ordinary hotels can choose to build their own cable TV front-end scheme, with digital TV set-top box as the program source. In this scheme, all programs are directly received by the digital TV set-top box. The equipment used in this scheme includes: signal amplifier, distributor, digital TV set-top box, adjacent frequency modulator, signal mixer, standard cabinet and so on. Specifically, the digital cable TV signal sent by the TV station is first amplified by the signal amplifier and then transmitted to the distributor. The distributor divides this TV signal into several channels and then transmits it to several digital TV set-top boxes. The digital TV set-top box demodulates the wired signals respectively, outputs audio and video signals, and then transmits them to the adjacent frequency modulator, which then modulates these audio and video signals into radio frequency signals and transmits them to the signal mixer. The mixed RF signal is amplified again and finally output to the original cable TV network of our unit for TV to watch directly without digital TV set-top box. As for the number of TV sets, it can be expanded indefinitely.
