Abstract

A system and method for wireless data transfer between a computer and a telephone line using a remote media interface (RMI). The computer bidirectionally transfers the data to the RMI using an infrared (IR) signal. The RMI acts as an interface between the computer and the telephone line. The wireless data transfer system of the present invention includes an IR transceiver housed on the computer and an IR transceiver housed on the RMI. The RMI includes a data access arrangement (DAA) for converting the data received from the computer into a signal suitable for transmission over the telephone line and vice versa. The RMI also includes an external data interface connected to the telephone line that receives and transmits the signal over the telephone line. A soft modem is installed on the computer whereby at least part of the soft modem uses software to perform the function of a digital signal processor.

Claims

1. A remote media interface for wireless transfer of data between a computer and a telephone line, comprising:

an infrared (“

IR”

) transceiver to bi-directionally communicate analog IR signals with the computer, wherein the computer has a soft-digital signal processor (“

soft-DSP”

) for converting analog IR signals to digital signals and for converting digital signals to analog IR signals;

a data access arrangement to convert an analog IR signal to a signal suitable for transmission over a telephone network and to convert a signal suitable for transmission over a telephone network to an analog IR signal; and

an external data interface to transmit and receive the signal over the telephone line.

2. The invention as set forth in claim 1, wherein the remote media interface further comprises a codec for compressing and decompressing the data.

3. The invention as set forth in claim 2, wherein the external data interface is a RJ-11 jack.
