Abstract:
This thesis presents a development of a system for broadcasting data over an MATV system which can be used for broadcasting particular data of each user in the hotel or hospital. The system uses biphase modulation for digital data transmission and reception. The particular data are provided as private information for each user. The general information such as news, advertisement or any service information can also be broadcast. The system, consisting of transmitter and receiver, is integrated with MATV. This system provides 127 receivers, 8 foreground and background colors and also supports both English and Thai languages, including graphical texts.
