. MULTI-FUNCTION TWO-WAY TV DISTRIBUTOR WITH DUMMY RESISTOR

摘要

75 저항 coaxial cable terminal resistance built-in composite two-way T-distributor (TV DISTRIBUTOR) of the present invention as the social environment changes from the industrial society environment to the high-speed multimedia service environment of the information society;1. Each building is constructed and used individually, especially in residential buildings;;One). With distributor for airwave TV (aka MATV),;2). Splitter for cable TV (aka CATV),;3). Functions such as a splitter for satellite TV (aka CS TV, BS TV),;From unidirectional to bidirectional, analog to digital, from one type of single service reception to more than two types of combined service reception, the function of the 75-ohm coaxial cable TV splitter used as the usage environment changes;;One). As a TV distributor, the function of simultaneously connecting and distributing MATV and CATV services,;2). One TV splitter, which simultaneously connects and distributes MATV, CATV, and satellite broadcasting (CS / BS TV) services,;3). It is a TV distributor for one 75 ohm coaxial cable that requires the function of connecting and distributing two-way analog and digital services as one TV splitter. As demand arises,;3. To support simultaneous distribution and distribution of multiple or multiple TV reception services using both analog and digital bi-directional, 75-ohm coaxial cable;;One). As one TV splitter, supports the use of MATV or CATV or satellite TV service separately connected, or;2) This is a TV divider with a built-in end resistance built-in type two-way TV divider designed to have the function of supporting the distribution distribution of more than one service at the same time according to the user's environment as MATV, CATV and satellite TV service.;In particular, as the use of two-way multi-channel high-speed multimedia service is activated, the connector for the coaxial cable on the secondary side of the TV distributor that is not in use must be terminated with a resistance of 75 ohms to prevent the generation of reflected waves and to impair the proximity receiver. As it is possible to use high-quality service without generating a high voltage, the integrated TV splitter with built-in termination resistance of the present invention attaches a 75 ohm terminating resistor between the signal core wire and the ground at each secondary connector, so that a coaxial cable is inserted. When the connector is open, the signal core is automatically grounded through a 75 ohm terminating resistor, preventing the occurrence of reflected waves and using high quality interactive multimedia service based on coaxial cable. It is implicated.
