ABSTRACT:
A network interface cassette for coupling signals between a wireless network and a tape head in a cassette tape player. The network interface cassette includes an enclosure that is conformed to the cassette tape form factor. It contains a transceiver that converts base band signals for radio frequency communications within the wireless network. It also contains a network controller that is coupled to communicate the base band signals with the transceiver. The network controller converts digital audio signals to and from the base band signals. There is an audio processor that converts the digital audio signals to analog audio signals. A coupling means converts the analog audio signals to magnetic audio signals. The coupling means is aligned to couple the magnetic audio signals to the tape head. A power supply with batteries and a generator driven from the cassette player capstan are provided. A wireless user interface adapter is provided to couple microphone and audio signals to the apparatus. Plural communications requests are processed, and include a priority scheme to manage resource contention.
