发明名称 Remote communication system and method
摘要 A remote learning system combines on-line service information and remote user information with a television signal designed to be received by students using multimedia personal computers. The combined signal is then transmitted to all of the students at their personal computers. At each personal computer, the received signal is separated into its component parts by a VBI modem for display or control on/of the personal computers. Each personal computer is capable of communicating back to a main server over a network such as a public telephone network. A broadcasting facility integrates the information transmitted over the network from a single student with the television signal.
