Information bit stream distribution device, information bit stream conversion circuit, information bit stream distribution method, information bit stream decoding device, and information bit stream inverse conversion circuit

An information bit stream distribution method comprising:

• acquiring an information bit stream having a valid bit stream including transmission data and an invalid bit stream including dummy data, extracting, from the transmission data included in the valid bit stream of the information bit stream acquired, transmission data whose number of bits is represented by sb as first transmission data, and outputting, as a first information bit stream in which the first transmission data is transmitted at a first speed, an information bit stream having a valid bit stream including the first transmission data and an invalid bit stream including dummy data;
• and
• extracting, from the transmission data included in the valid bit stream of the information bit stream acquired, transmission data, whose number of bits is represented by st, other than the first transmission data as second transmission data, and outputting, as a second information bit stream in which the second transmission data is transmitted at a second speed, an information bit stream having a valid bit stream including the second transmission data and an invalid bit stream including dummy data,
• wherein the number sb is determined according to the first speed at which the first transmission data is transmitted,
• the number st is determined according to the second speed at which the second transmission data is transmitted,
• the number sb increases as the first speed increases. and
• the number st increases as the second speed increases.

An information bit stream decoding device comprising processing circuitry

• to extract, from a second information bit stream having a valid bit stream including second transmission data being other than a first transmission data and whose number of bits is represented by st and an invalid bit stream including dummy data, the second transmission data, and
• to extract, from a first information bit stream having a valid bit stream including the first transmission data whose number of bits is represented by sb and an invalid bit stream including dummy data, the first transmission data, and to generate an information bit stream having a valid bit stream including the first transmission data extracted and the second transmission data and an invalid bit stream including dummy data,
• wherein the number sb is determined according to the first speed at which the first transmission data is transmitted,
• the number st is determined according to the second speed at which the second transmission data is transmitted,
• the number sb increases as the first speed increases. and
• the number st increases as the second speed increases.
