Abstract

Disclosed is a device that provides the ability to manage any consumer grade electronic device which uses an infrared controller. By learning, storing and being able to recreate the infrared pulse of a device's infrared controller, the stand-alone infrared system (SIS) can now provide the control required to manage several consumer electronic devices concurrently. This capability is most advantageous when using information from multiple video and audio sources in the same presentation.

Stand-Alone Infrared System

      Disclosed is a device that provides the ability to manage
any consumer grade electronic device which uses an infrared
controller.  By learning, storing and being able to recreate the
infrared pulse of a device's infrared controller, the stand-alone
infrared system (SIS) can now provide the control required to manage
several consumer electronic devices concurrently.  This capability is
most advantageous when using information from multiple video and
audio sources in the same presentation.

      Referring to the figure, the SIS 10 memorizes an infrared code
by sampling an infrared input at a 1 MHz rate for a period of 120
ms. Subsequent processing reduces the storage required to store the
infrared data to less than 1 k bytes.  Being connected to a Personal
System/2* (PS/2) 11 via the parallel port, this allows for the
storage of any compressed infrared codes on disk or tape storage
devices. The compressed infrared codes can be fetched under program
control and loaded back into the SIS 10.  The SIS 10 via a command
set is then instructed to decompress the infrared data and recreate
it.  Each device to be controlled 13, 14, and 16 is connected to the
SIS 10 via a fiber-optic cable 18.  The infrared signal is sent over
the fiber-optic cables 18 to all devices connected to the SIS.  A
total of six devices can be managed by one SIS.

      Another feature of the SIS 10 is its ability to receive and
decode fifteen unique infrare...
