Abstract

A wireless transmitting method capable of simplifying a transmission packet. In which error correction codes C11 to C16 added to data information (FIG. 4A) sent from various equipments connected through a high-speed serial bus are removed to convert the data information into data information (FIG. 4B) in a predetermined wireless environment, and error correction codes C21 to C24 are added to the data information (FIG. 4B) in the predetermined wireless environment thus converted as shown in FIG. 4C for transmitting by wireless as shown in FIG. 4D.

Claims

1. A wireless transmitting method for converting data information transmitted from an apparatus connected through a wired transmission path into wireless data information and for transmitting the wireless data information, comprising the steps of:

removing an error correction code added to the data information;

converting the data information into predetermined wireless data information;

adding header information to the predetermined wireless data information converted in the step of converting; and

adding the error correction code removed in the step of removing to the predetermined wireless data information to be transmitted over a wireless transmission path.

2. The wireless transmitting method according to claim 1, wherein the step of converting includes dividing long data information into a plurality of portions and subjecting short data information to a padding processing, thereby converting the data information into wireless data information having a predetermined length.

3. The wireless transmitting method according to claim 1, further comprising the step of providing the header information to include destination information indicative of a destination of the wireless data information.

4. The wireless transmitting method according to claim 1, further comprising the step of providing the header information to include effective time information describing a time at which the wireless data information is to be sent.

5. The wireless transmitting method according to claim 1, wherein the wireless transmitting step includes adding an error correction code to each of the predetermined wireless data information and the header information to be transmitted by the wireless method.

6. The wireless transmitting method according to claim 1, further comprising the step of providing the wire transmission path as a high-speed serial bus.

7. A wire transmitting method for converting data information received by wireless transmitting means into wired data information and for transmitting the wired data information, comprising the steps of:

removing an error correction code added to the data information;

converting the data information into predetermined wired data information by extracting wired header information from the predetermined wired data information converted in said step of converting; and

adding the error correction code to the predetermined wired data information and transmitting the summed information to an apparatus connected through a wired transmission path.

8. The wired transmitting method according to claim 7, further comprising the step of providing the wire transmission path as a high-speed serial bus.

9. The wire transmitting method according to claim 7, wherein the converting step includes slicing wireless header information from the data information and a padding processed portion when present.

10. The wired transmitting method according to claim 9, wherein the converting step comprises including effective time information in the wireless header information and converting the data information into predetermined wire data information only when the effective time information is valid.

11. A wireless transmitting apparatus for converting data information transmitted from an apparatus connected through a wired transmission path into wireless data information and for transmitting the wireless data information, comprising:

converting means for removing an error correction code added to the data information and for converting the data information into predetermined wireless data information

adding means for adding header information to the predetermined wireless data information converted by the converting means; and

transmitting means for adding the error correction code to the predetermined wireless data information to be transmitted over a wireless transmission path.

12. The wireless transmitting apparatus according to claim 11, wherein the converting means includes means for dividing long data information into a plurality of portions and for carrying out a padding processing on short data information in order to convert the data information into wireless data information having a predetermined length.

13. The wireless transmitting apparatus according to claim 11, wherein the header information includes destination information indicative of a destination of the wireless data information.

14. The wireless transmitting apparatus according to claim 11, wherein the header information includes effective time information describing a time at which the wireless data information is to be sent.

15. The wireless transmitting apparatus according to claim 11, wherein the wireless transmitting means includes means for adding an error correction code to each of the predetermined wireless data information and the header information to be transmitted by wireless.

16. The wireless transmitting apparatus according to claim 11, wherein the wired transmission path is a high-speed serial bus.

17. A wired transmitting apparatus for converting data information received by wireless transmitting means into wire data information and for transmitting the wired data information, comprising:

converting means for removing an error correction code added to the data information and for converting the data information into predetermined wired data information

means for extracting wired header information from the predetermined wired data information converted by the converting means; and

means for adding the error correction code to the predetermined wired data information and transmitting the summed information from the means for adding to an apparatus connected through a wired transmission path.

18. The wired transmitting apparatus according to claim 17, wherein the wired transmission path is a high-speed serial bus.

19. The wired transmitting apparatus according to claim 17, wherein the converting means includes means for slicing wireless header information from the data information and for slicing a padding processed portion when present.

20. The wired transmitting apparatus according to claim 19, wherein the converting means includes means for referring to effective time information included in the wireless header information and for converting the data information into predetermined wire data information only when the effective time information is valid.
