Abstract

Described is a hardware implementation to provide a single master control (MC) device to control and operate an entire set of components in a single entertainment system. The implementation pertains to devices that utilize common connections, such as cable, audio or television, and the same power line, or a control bus, so as to enable individual components to communicate together.

Single Master Control for Entertainment Systems

      Described is a hardware implementation to provide a single
master control (MC) device to control and operate an entire set of
components in a single entertainment system.  The implementation
pertains to devices that utilize common connections, such as cable,
audio or television, and the same power line, or a control bus, so as
to enable individual components to communicate together.

      Typically, every component of an entertainment system comes
equipped with its own remote control device.  The components are
interconnected to create individual entertainment system operations.
Difficulty can be experienced in choosing the correct remote device
in changing channels, volume, or other functions.  For example,
should a user wish to view a pre- recorded tape, the user must insert
the tape and start the VCR machine.  Then the TV channel must be
changed to the proper input so as to complete a playing process.
Also, television sets equipped with a picture in a picture (PIP) and
swap features can be difficult knowing which tuner is currently
active for the screen in question.

      In prior art, attempts have been made to solve the
interchangeable aspects of the entertainment system.  Universal
remote devices, for example, solves the problem of having multiple
controls, but still requires the user to know which device must be
controlled.  Infrared repeaters have been tried in an attempt to send
multiple commands to multiple devices.  The problem here is the
incompatibility of many of the components to do different functions.

      The concept described herein provides a means of enabling
individual components of the entertainment system to communicate to
each other through the use of a MC device.  Components are linked
together and a standard communication protocol ensures the user that
