Abstract

An arithmetic unit comprises a video input unit to which is input recorded video information obtained by taking a video of a human, a memory which stores human motion information as information related to movement of the human, and a transmission unit which determines importance of the human motion information, and sends the recorded video information and the human motion information to an external device so that availability of the human motion information in the external device will increase more for the human motion information determined as having high importance.

Claims

1. An arithmetic unit, comprising:

a video input unit to which is input recorded video information obtained by taking a video of a human;

a memory which stores human motion information as information related to movement of the human; and

a transmission unit which determines importance of the human motion information, and sends the recorded video information and the human motion information to an external device so that availability of the human motion information in the external device will increase more for the human motion information determined as having high importance.

2. The arithmetic unit according to claim 1,

wherein the transmission unit sends the recorded video information and the human motion information upon synchronizing the human motion information with the recorded video information.

3. The arithmetic unit according to claim 1, further comprising:

a redundancy unit which generates redundant human motion information obtained by making redundant the human motion information in a number of redundancies according to the importance,

wherein the transmission unit additionally sends the redundant human motion information to the external device.

4. The arithmetic unit according to claim 3,

wherein the transmission unit sends the redundant human motion information to the external device upon synchronizing the redundant human motion information with the human motion information determined has having high importance.

5. The arithmetic unit according to claim 1, further comprising:

a packet generation unit which divides integrated data of the recorded video information and the human motion information into a plurality of packets,

wherein the transmission unit sends packets containing the human motion information to the external device by setting a priority of the packets containing the human motion information to be higher than other packets.

6. The arithmetic unit according to claim 1, further comprising:

an ECC adding unit which generates a human motion correction code as an ECC of the human motion information having an error correcting capability according to the importance,

wherein the transmission unit additionally sends the human motion correction code to the external device.

7. The arithmetic unit according to claim 6,

wherein the transmission unit sends the human motion correction code to the external device upon synchronizing the human motion correction code with the human motion information determined has having high importance.

8. The arithmetic unit according to claim 1,

wherein the transmission unit determines the importance based on a condition received from the external device.

9. The arithmetic unit according to claim 1,

wherein the transmission unit determines that importance is high as changes in movement of the human are greater.

10. The arithmetic unit according to claim 1,

wherein the transmission unit determines that importance is high when movement of the human coincides with a predetermined status.

11. A transmission program to be executed in an arithmetic unit comprising a memory which stores human motion information as information related to movement of a human,

wherein the transmission program causes the arithmetic unit to:

receive input of recorded video information obtained by taking a video of a human; and

determine importance of the human motion information, and send the recorded video information and the human motion information to an external device so that availability of the human motion information in the external device will increase more for the human motion information determined as having high importance.

12. A transmission method to be executed by an arithmetic unit comprising a memory which stores human motion information as information related to movement of a human,

wherein the transmission method comprises the steps of:

receiving input of recorded video information obtained by taking a video of a human; and

determining importance of the human motion information, and sending the recorded video information and the human motion information to an external device so that availability of the human motion information in the external device will increase more for the human motion information determined as having high importance.
