Infrared receiver, infrared bridge device and methods for use therewith
View Patent ↗An infrared data receiver includes an infrared detector for generating a received signal from an infrared input signal. A sampling module generates a sequence of sampled data from the received signal. A plurality of processing modules are included, wherein each processing module is capable of detecting and decoding data in at least one of a plurality of data formats. Each processing module analyzes the sequence of sampled data for its particular data formats. When a processing module detects one of its data formats, it generates a detection signal and decodes the sequence of sampled data into decoded data. A controller module receives the detection signal from one of the plurality of processing module, and disables the other ones of the plurality processing modules.
1. A method comprising:
generating at an infrared data receiver a received signal from an infrared input signal;
generating at the infrared data receiver a sequence of sampled data from the received signal at a first sample rate;
analyzing at the infrared data receiver the sequence of sampled data in a plurality of data formats; and
when one of the plurality of data formats is detected:
generating at the infrared data receiver a detection signal that indicates the one of the plurality of data formats; and
decoding at the infrared data receiver the sequence of sampled data into decoded data; and
modifying the first sample rate to a second sample rate based on the one of the plurality of data formats.
2. The method of claim 1 further comprising:
decimating the sequence of sampled data into a plurality of data streams at a plurality of data rates.
3. The method of claim 2 wherein the step of decimating is disabled when the one of the plurality of data formats is detected.
4. The method of claim 1 wherein the plurality of data formats include at least one of: a serial infrared data format in accordance with Infrared Data Association (IrDA) standards, a medium infrared data format in accordance with IrDA standards, a fast infrared data format in accordance with IrDA standards, a very fast infrared data format in accordance with IrDA standards, and an ultra fast infrared data format in accordance with IrDA standards.
5. The method of claim 1 further comprising:
converting the decoded data into formatted data in a client device format; and
coupling the formatted data to a client device.
6. The method of claim 5 further comprising:
receiving client data from the client device;
when the one of the plurality of data formats is detected:
encoding the client data into encoded data in the one of the plurality of data formats; and
converting the encoded data into an infrared output signal.
