Abstract

A new class of consumer multimedia products are emerging in the industry. A hybrid Personal Computer (PC)/Television (TV) (DSS-PC) will combine the capabilities of a multimedia PC, cable ready high-resolution television, Digital Satellite Broadcast settop box, and consumer electronics control. This system will have the ability of supporting different input devices to allow the customer to enter information in wireless keyboard with integrated mouse, remote control with integrated mouse, and any other pointing devices with mouse function. Currently, most of these devices conflict with each other. If user 1 is using the keyboard and writing an email, user 2 could take the remote control and close down the application or take control of the mouse functions.

Master Control Lock Key for Input Devices in a Personal Computer/Television
System

      A new class of consumer multimedia products are emerging in the
industry.  A hybrid Personal Computer (PC)/Television (TV) (DSS-PC)
will combine the capabilities of a multimedia PC, cable ready
high-resolution television, Digital Satellite Broadcast settop box,
and consumer electronics control.  This system will have the ability
of supporting different input devices to allow the customer to enter
information in wireless keyboard with integrated mouse, remote
control with integrated  mouse, and any other pointing devices with
mouse function. Currently,  most of these devices conflict with each
other.  If user 1 is using the  keyboard and writing an email, user 2
could take the remote control and  close down the application or take
control of the mouse functions. To  solve this problem, it is
necessary to provide a master control lock key function in each
device that allows the user to lock out other devices while using the
computer.  Only that user can release the lock  so other input
devices work again.

      A hybrid PC/TV is emerging in the market place which will allow
a new set of products to sit in the living room with the rest of the
consumer electronic equipment.  This type of system, since it is a
computer, has a wireless keyboard and remote control device.  The
customer will use the keyboard when doing PC type applications
(email, word processor) and a remote control when using the TV, A/V
equipment, or surfing the web.  Furthermore, this new type of system
will allow new games and other applications that will require the use
of many input  devices, providing a social setting and allowing the
whole family to interact with this PC/TV product.

      The current PC/TV products have the problem that keyboards and
remote controls overrun each other.  If a user uses the remote
control's mouse, the second user using the integrated mouse in the
keyboard can move the mouse at the same time.  This interruption can
currently happen  inadvertently, when another input device is
casually handled, moved or can happen intentionally in a competition
for control between people  in the room.  To prevent this problem
with mouse control or key control,  a new technique is necessary to
override the input function on one of the  devices.

      A master control lock key can be implemented on each wireless
device.  This master control lock key will disable any other input
device.  The master user can use the master inpu...
