Abstract

In a wireless communication system including at least a plurality of wireless communication terminal apparatuses each including first and second wireless communication apparatuses, the first wireless communication apparatus includes first and second wireless communication parts. The first wireless communication part transceives digital data in a half-duplex communication mode via a first wireless communication path, and the second wireless communication part transceives digital data in a full-duplex communication mode via a second wireless communication path. A first control part controls transmission of digital data for the first and second wireless communication parts. The second wireless communication apparatus includes third and fourth wireless communication parts. The first control part controls the first and second wireless communication parts to transmit identical digital data from both of the first and second wireless communication parts when instructing the second wireless communication apparatus to transmit digital data.

Claims

1. A wireless communication system comprising first and second wireless communication apparatuses, wherein:

the first wireless communication apparatus includes;

a first wireless communication part configured to transceive via a first wireless communication path digital data in a half-duplex communication mode;

a second wireless communication part configured to transceive via a second wireless communication path digital data in a full-duplex communication mode; and

a first control part configured to control transceiving of digital data for the first and second wireless communication parts,

the second wireless communication apparatus includes;

a third wireless communication part configured to transceive via the first wireless communication path digital data in the half-duplex communication mode; and

a fourth wireless communication part configured to transceive via the second wireless communication path digital data in the full-duplex communication mode,

the first control part is configured to control the first wireless communication part to transmit a first command to the third wireless communication part, and

the first control part is configured to control the second wireless communication part to transmit a second command to the fourth wireless communication part, the second commend being the same as the first command.

2. The wireless communication system of claim 1, wherein the first control part is configured to control the first wireless communication part to transmit the first command and the second wireless communication part to transmit the second command when instructing the second wireless communication apparatus to transmit digital data.

3. The wireless communication system of claim 1, wherein:

the second wireless communication apparatus further includes a second control part configured to receive a notification associated with each of the first and second commands,

the first control part is configured to control the first wireless communication part to transmit a first frame number along with the first command and to control the second wireless communication part to transmit a second frame number along with the second command, the first frame number being the same as the second frame number, and

the second control part is configured to abandon the first command or the second command upon determining that the first sequence number is the same as the second sequence number.

4. The wireless communication system of claim 1, wherein:

the first wireless communication apparatus includes a player for reproduction of a disc, and

the second wireless communication apparatus includes a television receiver.

5. The wireless communication system of claim 1, wherein:

the first wireless communication apparatus includes a television receiver, and

the second wireless communication apparatus includes a player for reproduction of a disc.

6. A first wireless communication apparatus comprising:

a first wireless communication part configured to transceive via a first wireless communication path digital data in a half-duplex communication mode;

a second wireless communication part configured to transceive via a second wireless communication path digital data in a full-duplex communication mode; and

a control part configured to control the first wireless communication part to transmit a first command to a second wireless communication apparatus, and to control the second wireless communication part to transmit a second command to the second wireless communication apparatus, the second commend being the same as the first command.

7. The first wireless communication apparatus of claim 6, wherein the control part is configured to control the first wireless communication part to transmit the first command and the second wireless communication part to transmit the second command when instructing the second wireless communication apparatus to transmit digital data.

8. The first wireless communication apparatus of claim 6, wherein the control part is configured to control the first wireless communication part to transmit a first frame number along with the first command and to control the second wireless communication part to transmit a second frame number along with the second command, the first frame number being the same as the second frame number.

9. The wireless communication system of claim 6, wherein the first wireless communication apparatus includes a player for reproduction of a disc.

10. The wireless communication system of claim 6, wherein the first wireless communication apparatus includes a television receiver.

11. A second wireless communication apparatus comprising:

a first wireless communication part configured to receive, via a first wireless communication path and from a first wireless communication apparatus, a first command in a half-duplex communication mode;

a second wireless communication part configured to receive, via a second wireless communication path and from a second wireless communication apparatus, a second command in a full-duplex communication mode; and

a control part configured to identify a first frame number associated with the first command and a second frame number associated with the second command and abandon the first command or the second command upon determining that the first frame number and the second frame number are the same.

12. The second wireless communication apparatus of claim 11, wherein:

the first wireless communication apparatus includes a player for reproduction of a disc, and

the second wireless communication apparatus includes a television receiver.

13. The second wireless communication apparatus of claim 11, wherein:

the first wireless communication apparatus includes a television receiver, and

the second wireless communication apparatus includes a player for reproduction of a disc.
