摘要： An apparatus and method of transferring a transmission stream in a digital interface which inserts the program number selected by a user into a predetermined region of the MPEG2-TS if a multi-program is included in a channel, and transmits the MPEG2-TS including the selected program number through the digital interface to record and reproduce the MPEG2-TS. The apparatus includes a transmitting device for transmitting an input stream, a receiving device for recording and reproducing the stream, a TP demultiplexer for demultiplexing a multi-program from the input stream or a reproduced program, a recording section for recording program information selected by the user in a specified region of the demultiplexed stream, and a control section for controlling an operation of the recording section. The multi-program is transmitted to the receiving device through the digital interface, and a program selected by the user from the multi-program is selected by the receiving section.

摘要： A signal transmission method and apparatus provides a digital transmission path and an analog transmission path between a signal output apparatus and a signal input apparatus. An audio/video signal is transmitted from the signal output apparatus to the signal input apparatus over the digital transmission path. When a user requests an on screen display (OSD) from the signal output apparatus, a controlling unit of the signal output apparatus judges a volume of the data to be displayed via the OSD. If the volume exceeds a preset limit, the OSD is transmitted to the signal input apparatus over the analog transmission path. If the volume does not exceed the preset limit, the OSD is transmitted to the signal input apparatus over the digital transmission path. The controlling unit of the signal output apparatus informs a controlling unit of the signal input apparatus of the intended path of the OSD, so that the signal input apparatus can process the OSD in the appropriate manner.
