`ABSTRACT
`
`Disclosed herein is a method and System for employing
`power-saving States/modes in electronic devices. The elec
`tronic device may be adapted to determine whether an
`end-user is physically present when the electronic device is
`in operation or when an end-user display apparatus is
`inactive. The electronic device may be adapted to prompt an
`end-user to respond with an appropriate response. Upon
`determining that the end-user is not physically present, the
`electronic device may be adapted to enter at least one of a
`plurality of power-Saving modes. The end-user, the network,
`and the electronic device may each be able to Set the
`power-saving modes. The electronic device may also enter
`at least one of a plurality of power-Saving modes by default.
`The electronic device may be adapted to maintain an end
`user's Settings and preferences by employing the power
`Saving modes.

`
`BACKGROUND OF THE INVENTION
`0006 Cable television (TV) has become a widely sub
`scribed to commodity. Cable TV typically comprises a
`plurality of audio/video (A/V) transmissions accumulated in
`a central office, for example. The A/V transmissions may be
`accumulated in a content Server, for example.
`0007. A content server is an information storage unit
`adapted to collect, accumulate, package, disseminate, and
`broadcast multimedia-program data/information to clients at
`various locations remote from the central office.
`0008. A common central content server may be located in
`a central office of a Service provider. The content Server may
`comprise a plurality of Servers residing in multiple geo
`graphic locations.
`0009 Typically, cable TV transmissions (channels) are
`distributed to end-users over cables, thus cable TV. The
`channels may be distributed from a content Server located at
`a local cable TV service provider's location. The service
`provider's content Server is adapted to transmit all of the
`channels simultaneously on a Single shared cable to an
`end-user location.
`0.010
`Multiple clients, end-users, and/or customers sub
`scribe to the channels and/or services provided by the
`content Server of the Service provider. A television Set and a
`set-top-box (STB) may be located at the end-user's location
`
`to decode and display the channels. The STB provides
`end-users access to (i.e., decodes) only those channels that
`the end-user Subscribes.
`0011) Ordinarily, there may be a signal distribution unit
`situated at the cable TV service provider's location. The
`Signal distribution unit may be adapted to receive all chan
`nels via at least one Satellite Signal-receiving unit, and
`Subsequently via at least one Satellite. The Subscribing
`end-user's STB is connected to the end-user's TV set. The
`end-user may be provided with a Smart card for authentica
`tion and identification purposes.
`0012 Each end-user may subscribe to different channel
`packages and the number of channels Subscribed to by each
`end-user may vary. Cables connect the Signal distribution
`unit at the service provider's location to each STB and TV
`Set at each individual end-user location. The Signal distri
`bution unit transmits all of the received channels to all of the
`end-user locations at once.
`0013 The STB is adapted to permit access to (viewing
`of) channels that the end-user has Subscribed, while barring
`access to (denying viewing of) channels that the end-user
`has not Subscribed. The end-user may select a Subscribed
`channel for viewing by remotely controlling the STB, caus
`ing the STB to decode and Send a particular channel to the
`TV set for display and viewing.
`0014 Occasionally, end-user's Switch off their TV sets
`and leave the STB Switched on. When an end-user is not
`Viewing received and decoded multimedia-program content,
`i.e., when the STB is left Switched on, power is being
`wasted.
`0015 Occasionally, end-users forget to Switch off both
`their TV sets and the STB. When an end-user is not viewing
`received, decoded, and displayed multimedia-program con
`tent, i.e., when the TV set and the STB are left Switched on,
`power is being wasted.
`0016 Further limitations and disadvantages of conven
`tional and traditional approaches will become apparent to
`one of skill in the art, through comparison of Such Systems
`with Some aspects of the present invention as Set forth in the
`remainder of the present application with reference to the
`drawings appended hereto.
`
`SUMMARY OF THE INVENTION

`may be one of Switched off and inactive.
`0075. In an embodiment according to the present inven
`tion, in the POWER-ON mode, all circuits of the electronic
`devices may be one of Switched-on and active.
`
`0076. In an embodiment according to the present inven
`tion, monitoring activity of the electronic device may be
`performed during electronic device Start-up. Upon determin
`ing that a valid end-user is present, the electronic device may
`be adapted to enter the POWER-ON mode.
`0077. In an embodiment according to the present inven
`tion, determining whether a display apparatus is one of
`active and inactive may comprise evaluating at least one
`component of the display apparatus.
`0078. In an embodiment according to the present inven
`tion, the electronic device may enter the POWER-ON mode
`upon being Switched on, wherein monitoring activity of the
`electronic device may be performed. The electronic device
`may enter a different power-Saving mode depending upon
`whether an end-user is one of present and absent.
`0079. In an embodiment according to the present inven
`tion, the electronic device may enter the POWER-ON mode
`upon being Switched on, wherein monitoring activity of the
`electronic device may be performed. The electronic device
`may enter a different power-Saving mode depending upon
`whether a display apparatus is one of active and inactive.
`0080. In an embodiment according to the present inven
`tion, the electronic device may enter a power Saving mode
`when an end-user presses one of a button and a key on at
`least one of a remote control device, the electronic device,
`and a peripheral associated electronic device.
`0081. In an embodiment according to the present inven
`tion, the electronic device may enter a power Saving mode
`when an end-user presses a Sequence of one of buttons and
`keys on at least one of the remote control device, the
`electronic device, and the peripheral associated electronic
`device.
`0082 In an embodiment according to the present inven
`tion, the electronic device may enter a power Saving mode
`when an end-user enters at least one of a password and
`username on at least one of the remote control device, the
`electronic device, and the peripheral associated electronic
`device.
`0083. In an embodiment according to the present inven
`tion, the electronic device may enter a power Saving mode
`when an end-user enters a particular response to an inter
`active question delivered by the electronic device upon at
`least one of the remote control device, the electronic device,
`and the peripheral associated electronic device.
`0084.
`In an embodiment according to the present inven
`tion, the electronic device may enter a power Saving mode
`when an end-user employs a biometric authentication tech
`nique via at least one of the remote control device, the
`electronic device, and the peripheral associated electronic
`device.
`0085. In an embodiment according to the present inven
`tion, the electronic device may enter a power-saving mode
`depending upon a State of at least a portion of at least one of
`hardware, firmware, and Software in the electronic device.
`0086 These and other features and advantages of the
`present invention may be appreciated from a review of the
`following detailed description of the present invention,
`along with the accompanying figures in which like reference
`numerals refer to like parts throughout.
