RECEIVER TELEVISION TYPES REPAIRING RECEIVER TELEVISION SYSTEM By Sarbini, S.Pd (SMK Muh 3 Yogyakarta)
Teknologi dan Rekayasa RECEIVER TELEVISION TYPES Black White Television Colour Television Cabel Television Satelit Television TV IP(Internet Protocol ) TVIO HD(HIGH DEFINITION) TV TELEVISION BW TV COLOUR TV CABEL TV SATELIT TV TVIP TVIO HD TV
Teknologi dan Rekayasa DIFFERENT OF BLACK WHITE TELEVISION AND COLOUR TELEVISION BLACK WHITE TV 1. CRT (Catoda Ray Tube) hitam putih with one electron gun 2. No color processing (color matrik) 3. Sound IF taken after the video detector COLOUR TV 1. CRT (Catoda Ray Tube) colour with 3 electron gun (Red,Green, Blue) 2. There are color matric processing (RGB) 3. Sound IF taken before the video detector
Teknologi dan Rekayasa SATELIT TELEVISION FORM SATELIT TELEVISION ANTENA Receiver Satelit Television with remote control
Teknologi dan Rekayasa CABEL TELEVISION TV CABEL INSTRUMENTS : Receiver,Video Beta,VCD,DVD player Disecq switch/ spliter 1 : 4 dan 1 : 2 Coaxial cable RG 6 U 75 ohm. Conector RF/Arial. Booster Amplifier VS-80 or equivalent. Nippon Booster V-5000 Antena Parabola
Teknologi dan Rekayasa 1.BOOSTER TV KABEL : Receive, filter the noise signal from the Audio and Video signal RF (radio frekuency) Receiver, Beta Video, VCD, DVD player etc. Transfer return the results amplifying to TV Tuner. Amplify the received signal Booster frekuency able to receive VHF, UHF and FM (Booster VS- 80 for 30 pieces and 20 TV CH )
Teknologi dan Rekayasa 2. SPLITER a.Manage frekuency traffic generated by the VS-80 and align to the input Tv Tuner. b. Counteract the voltage from Tuner in order is not overlapping.
Teknologi dan Rekayasa ADVANTAGE CABEL INTERNET 24 hour access Cheap Without dialing Process(No sign of busy tone when all the channels to ISPs are solid, without a phone call because we missed busy.
Teknologi dan Rekayasa Speed data transmission (Upstream and downstream) higher (28.8 kbps: 128 kbps: 38 Mbps (Mega bits per second). Speed data transmission is not affected by the distance between customers and service providers. Speed data transmission is very high can be achieved if the cable that is used in the trunk and distribution system is a fiber optic. Coaxial cable is only used as a drop cable (between the customer and the distribution of tap)
Teknologi dan Rekayasa WEAKNESS CABEL INTERNET There are decrease in performance with the addition of customers
