Abstract

A recoding medium storing a computer program, which, when executed by a processor, cause the processor to perform operations including: determining a pattern of a change in luminance, by modulating the signal to be transmitted; and transmitting the signal, by at least one light emitter changing in luminance according to the determined pattern of the change in luminance. The signal has a plurality of blocks, each block of the plurality of blocks includes (i) address information that indicates a position of a data segment in the signal and (ii) the data segment. In the transmitting, the signal is transmitted repeatedly at different times. The address information is used to identify a same location of the block data segment in the signal transmitted at a first time and in the signal transmitted at a second time, which is different from the first time. The signal has a check signal.

Claims

1. A non-transitory recording medium storing a computer program, which, when executed by a processor, causes the processor to perform operations comprising:

determining a pattern of a change in luminance, by modulating the signal to be transmitted; and

transmitting the signal, by at least one light emitter changing in luminance according to the determined pattern of the change in luminance,

wherein, the signal has a plurality of blocks, each block of the plurality of blocks includes (i) address information that indicates a position of a data segment in the signal and (ii) the data segment, and

wherein, in the transmitting, the signal is transmitted repeatedly at different times,

wherein the address information is used to identify a same location of the block data segment in the signal transmitted at a first time and in the signal transmitted at a second time, which is different from the first time,

wherein the signal has a check signal.

2. The non-transitory recording medium according to claim 1,

wherein the check signal identifies each of the plurality of blocks.

3. A method comprising:

determining a pattern of a change in luminance, by modulating the signal to be transmitted; and

transmitting the signal, by at least one light emitter changing in luminance according to the determined pattern of the change in luminance,

wherein, the signal has a plurality of blocks, each block of the plurality of blocks includes (i) address information that indicates a position of a data segment in the signal and (ii) the data segment, and

wherein, in the transmitting, the signal is transmitted repeatedly at different times,

wherein the address information is used to identify a same location of the block data segment in the signal transmitted at a first time and in the signal transmitted at a second time, which is different from the first time,

wherein the signal has a check signal.

4. An apparatus comprising:

a processor; and

a recording medium storing a computer program, which, when executed by the processor, causes the processor to perform operations comprising;

determining a pattern of a change in luminance, by modulating the signal to be transmitted; and

transmitting the signal, by at least one light emitter changing in luminance according to the determined pattern of the change in luminance,

wherein, the signal has a plurality of blocks, each block of the plurality of blocks includes (i) address information that indicates a position of a data segment in the signal and (ii) the data segment, and

wherein, in the transmitting, the signal is transmitted repeatedly at different times,

wherein the address information is used to identify a same location of the block data segment in the signal transmitted at a first time and in the signal transmitted at a second time, which is different from the first time,

wherein the signal has a check signal.
