EQUIPMENT AND METHOD FOR CREATING BIDIRECTIONAL TELEVISION SIGNAL AND TRANSMISSION SYSTEM OF BIDIRECTIONAL TELEVISION SIGNAL

Japanese Patent JPH0846950

A

PURPOSE: To execute the preparation of codes and data demarcating a bidirectional application together with video and audio programs for reliability and convenience in transmission. CONSTITUTION: The compressed audio and video programs are divided into transport packets and the related bidirectional application is formed into function module and compressed. The signal module is conditioned for stopping or restarting the bidirectional application through a receiver. When the change of received signal component occurs at the signal module, respective receivers are multiplexed on a packet stream so as to be reprogrammed. Each module is composed of the integer pieces of code/data transport packets and header transport packets. Therefore, the bidirectional television preparing device is composed of an interactive component source 10, video source 17 and 1st and 2nd audio sources 20 and 23 (bilingual audio) and the packet is practically multiplexed in time division manner.
