Abstract

The present invention is a method and apparatus for controlling a device by a remote controller. A receiving unit receives a first signal emitted by the remote controller and converts the received signal into a data stream. A communication medium carries the data stream from the receiving unit. A transmitting unit receives the data stream from the communication medium and converts the received data stream into a second signal compatible with the device.

Claims

1. A system comprising:

a receiving unit to provide a data stream, the receiving unit comprising;

a signal receiver that receives a first signal from a remote controller for controlling a device, the signal receiver translating the first signal into a sequence of data code, the signal receiver inserting an information type into the sequence of data code and the signal receiver encoding the inserted sequence of data code to provide a data stream;

a receiver buffer coupled to the signal receiver, that stores the data stream, to match a transmission rate; and

a communication medium coupled to the receiving unit that carries the data stream.

2. The system of claim 1, wherein the communication medium is compatible with a 1394 serial bus.

3. The system of claim 2, wherein the communication medium is one of:

an electrical cable, a glass cable, a plastic cable, a fiber optic cable, and a radio frequency link.

4. The system of claim 1, wherein the first signal is an optical signal.

5. The system of claim 4, wherein the optical signal is an infrared signal.

6. A system comprising:

a receiving unit that receives a first signal from a remote controller for controlling a device, the receiving unit translating the first signal into a sequence of data code, the receiving unit inserting an information type into the sequence of data code and the receiving unit encoding the inserted sequence or data code to provide a data stream;

a communication medium coupled to the receiving unit to carry the data stream; and

a transmitting unit coupled to the communication medium to receive the data stream, the transmitting unit comprising;

a transmitter buffer that stores the data stream to match a processing rate,

a processor coupled to the transmitter buffer, that processes data stream to produce a decoded data stream at the processing rate, and

a signal transmitter coupled to the processor, that transits the decoded data stream into a second signal.

7. The system of claim 6, wherein the communication medium is compatible with a 1394 serial bus.

8. The system of claim 7, wherein the communication medium is one of:

an electric cable, a glass cable, a plastic cable, a fiber optic cable, and a radio frequency link.

9. The system of 6, wherein the second signal is an optical signal.

10. The system of claim 9, wherein the optical signal is an infrared signal.

11. An apparatus comprising:

a signal receiver that receives a signal, the signal receiver translating the received signal into a sequence of data code, the signal receiver inserting an information type into the sequence of data code, and the signal receiver encoding the inserted sequence of data code to provide a data stream for transmission at a transmission rate; and

a receiver buffer coupled to the signal receiver, that stores the data stream to match the transmission rate.

12. The apparatus of claim 11, wherein the signal is an optical signal.

13. The apparatus of claim 12, wherein the optical signal is an infrared signal.

14. The apparatus of claim 11 further comprising a receiver medium interface coupled to the receiver buffer, that generates the data stream from the stored sequence of digital data.

15. An apparatus comprising:

a transmitter buffer that stores a data stream to match a processing rate, the data stream being provided from a sequence of data code, the sequence of data code having an inserted information type, the sequence of data code being translated from a signal;

a processor coupled to the transmitter buffer, that processes the data stream to produce a decoded data stream at the processing rate; and

a signal transmitter coupled to the processor, that transmits the decoded data stream into the signal.

16. The apparatus of claim 15, wherein the signal is an optical signal.

17. The apparatus of claim 16, wherein the optical signal is an infrared signal.

18. The apparatus of claim 15 further comprising a transmitter medium interface coupled to the transmitter buffer, that receives the data stream.

19. A method comprising:

translating a signal into a sequence of data code;

inserting an information type into the sequence of data code;

encoding the inserted sequence of data code to provide a sequence of digital data for transmission at a transmission rate; and

storing the sequence of digital data in a receiver buffer to match the transmission rate.

20. The method of claim 19, further comprising:

generating a data stream from the stored sequence of digital data by a receiver medium.

21. The method of claim 19, wherein the information type is one of:

processing the data stream, by a processor, at the processing rate to produce a decoded data stream; and

transmitting the decoded data stream into the signal by a signal transmitter.

25. The method of claim 24 further comprising receiving the data stream by a transmitter medium.

26. The method of claim 25 further comprising converting the data stream into data having electrical characteristics compatible with the transmitter buffer.

27. The method of claim 24, wherein processing the data stream comprises:

matching the information type in the data stream; and

performing an error detection on the matched data stream.
