Signal transmission system for transmitting programed information such as programed instruction
First Claim
1. A signal transmission system for transmitting programmed information including signals corresponding to a plurality of program materials, comprising at a transmitter end:
- a program material source for producing said signals corresponding to said plurality of program materials;
means for producing a plurality of identification signals a respective one of which denotes each of said signals corresponding to said plurality of program materials;
means for producing a plurality of label signals each of which denotes a minimum program material group comprising a minimum significant information unit composed of one or more of said signals corresponding to said program materials;
means for receiving said identification and label signals to form a program material control signal composed of a plurality of combinations of said label and identification signals, each of said combinations including a respective label signal and one or more identification signals which denote one or more of said signals corresponding to said program materials in said minimum program material group denoted by said respective label signal;
composite signal forming means for receiving said signals corresponding to said program materials and said program material control signal to form a composite signal; and
means for transmitting said composite signal; and
at a receiver end;
means for receiving said composite signal;
means for reproducing at least a part of said program material control signal from the received composite signal;
label determining means for determining a label signal of a minimum program material group to be displayed;
identification signal detecting means for receiving said reproduced program material control signal and said determined label signal to detect one or more identification signals which form one of said combinations in said reproduced program material control signal together with said determined label signal;
means for extracting from the received composite signal a minimum program material group of one or more of said signals corresponding to said program materials denoted by said one or more detected identification signals; and
means for displaying said one or more extracted signals corresponding to said program materials.

Abstract
A signal transmission system for transmitting programed information such as a programed instruction comprising at a transmitter end circuitry for producing a number of program materials and a control signal which is used at a receiver end to control the manner of sequentially connecting program materials in accordance with a response input of a student to construct at least one significant program. The system comprises at the receiver end circuitry for detecting the control signal, circuitry for extracting desired program materials in a desired sequence with the aid of the control signal in accordance with the response input of the student and apparatus for displaying the extracted desired program materials.
