Video on-demand system with a plurality of reception apparatus connected in a daisy chain connection
First Claim
1. A video on-demand system wherein video programs are selectively supplied and displayed in response to requests of viewers in a physically limited space, the system comprising:
- storage means for storing a plurality of video programs;
a delivery apparatus for selectively reading out and delivering, in response to request signals derived from the requests of the viewers, video information of the plurality of video programs, wherein each of the plurality of video programs is stored in the form of compressed codes in said storage means;
communication line means formed of a set of lines including a data line for serially transmitting the video information at a data rate equal to or higher than 100 Mbps, a strobe line for transmitting a strobe signal for regeneration of a clock signal to be used to transmit the video information, and a power supply line for supplying dc power;
a plurality of reception apparatus connected in a daisy chain connection to said delivery apparatus by said communication line means for outputting the request signals and selectively receiving the video information;
a plurality of reception apparatus installation means in a predetermined arrangement and having said plurality of reception apparatus respectively installed individually therein for allowing the viewers to view selected video programs; and
line laying means provided between said delivery apparatus and said plurality of reception apparatus and connecting said plurality of reception apparatus in a daisy chain connection to said delivery apparatus.

Abstract
A communication line used for connection of a system such as a video on-demand system which includes a delivery apparatus and a plurality of reception apparatus is formed from a data line to be used to serially transmit video information at a data rate equal to or higher than 100 MBps, a strobe line to be used to transmit a strobe signal for regeneration of a clock signal, and a power supply line to be used to supply power, and the delivery apparatus and the plurality of reception apparatus are connected by a daisy chain connection by the communication line. The wiring line length can be minimized by the daisy chain connection, and the system can be applied readily to a location wherein a space which can be used for installation of wiring lines is physically limited such as in an aircraft.
