An electronic device (50) includes an infrared transceiver (510) having adjustable infrared signal intensity capability. The electronic device (50) commences to establish communications with a secondary device (420 and/or 430) at a first power level, if the communication link is not established, the electronic device (50) increases the IR power level and tries again to establish communications. In an alternate embodiment, the electronic device (50) includes a power level table which keeps the power level which has been established for each secondary device (420, 430) using the method described above. The electronic device (50) before communicating with each of the secondary devices determines the proper power level to use depending on the secondary device (420, 430) it wants to communicate with. In still a further embodiment, instead of determining the power level to use at the start of the communications, an ongoing exchange of signal quality information is sent between the communicating devices in order to adjust the power level of the devices during the communication session.

Method for adjusting the power level of an infrared signal

A data communication receiver (100) includes a receiver (110) for receiving a message including at least one code, a database (155) for storing codes and image data associated with the codes, and a presentation element (150) for locating the at least one code in the database (155). The presentation element (150) then retrieves the image data associated with the at least one code. The image data associated with the at least one code is representative of at least one image. The data communication receiver (100) also includes a display (130) coupled to the presentation element (150) for presenting the at least one image as a graphic message.

Method and apparatus for presenting graphic messages in a data

A radio communication device (100) receives a radio frequency (RF) signal comprising at least first, second, and third words which include message information and error correction information, wherein the second and third words are redundant words associated with the first word. A processing unit (120) included in the radio communication device (100) compares each corresponding bit of the first, second, and third words to determine, for each corresponding bit, which of first and second bit values is a majority bit value and generates a fourth word which includes a bit for each corresponding bit, wherein each bit of the fourth word has a value equivalent to the majority bit value corresponding thereto. Error correction circuitry (135) coupled to the processing unit (120) performs error correction on each of the first, second, third, and fourth words utilizing the error correction information, subsequent to which the processing unit (120) selects message information included in one of the first, second, third, and fourth words for presentation when at least one of the first, second, third, and fourth words has been corrected.
