more than one TV set-top box way to share a

new balance mens!
tips to solve a one machine set-top box to watch and change a set-top box for TV viewing more than one method of thinking, the principle is to set-top box digital television signal into the whole traditional analog TV signals, the front set of intelligent set-top boxes charge card, you can set the switch in the future, free to open or close each customer's TV set-top box digital signal, the role of set-top box is wired cable in the entire digital signal into analog TV signals, the second half is a set-top box remote control panels, instead of the original TV remote control circuit,
new new balance shoes, remote control select units, if the internal tuner in the set-top boxes out the input of all analog TV signals,
new balance 574, external leads to a television outlet, connect a TV splitter, you can use two-thirds, quarters, six points,

new balance running shoes, three TVs,
new balance outlet, five television. . . . Complete a one machine set-top boxes crack the monopoly, we can find people who understand electronic circuit knowledge to help modification, to spend less than ten dollars, the national monopoly cable mad! Originally set-top box manufacturers can produce the second area, along the three, along the four set-top boxes, but they just do not do to help Zhou as a sin, it is uneven ah.
in-house tuner out all the input television signal. Input in the set-top box is a compressed digital signal, after demodulation is output through the Composite Video signal. The output is the input of the internal tuner.
in the input of the internal tuner out all television analog signals, outside leads to a television outlet, connect a TV splitter, you can use the three branches, four branches and six branches,
于丹的婚姻观 - Qzone日志, etc., it is entirely possible (in order to impedance matching suggested distributor in order to reduce interference between the TV). Before the best level in the distribution of ultra-high frequency amplification (about compensation 10db) signal loss caused by the branch distribution.
set-top box works: the input compressed digital signal, decoded by all television signals, and then through the internal tuner IF amplifier, frequency output video and audio after the separation. Through the external connection to the TV video and audio input terminals. Change process does not cut the original set-top box circuit, just use the 75 ohm feed line around Ceramic capacitor plus 1000P (to prevent external short-circuit when the impact of the original machine) TV signal output point in the whole welding look to the skin 75 ohm feeder ground (so-called ground, common ground is connected set-top box, which is the power of the negative) on it.
I wish you all a successful transformation, Do not trouble to go after the pot a pot back Yo!
