Upgradeable display device and method for controlling the same
A display device and a method of upgrading the same are disclosed. The display device, such as a Smart TV, may include a broadcast receiver for receiving a broadcast signal, a demultiplexer for demultiplexing the received broadcast signal, a decoder for decoding the demultiplexed broadcast signal, and a display for displaying the decoded broadcast signal. The display device may also include an external device interface for receiving upgrade data from an upgrade device. A controller may be configured to process the received broadcast signal for display on the display and to upgrade the display device using the received upgrade data. The upgrade data may include at least one function. A control module may be configured to assign the at least one function to at least one of the upgrade device or the controller to execute the function on the display device.
1. An upgradable multi-functional display device, comprising:
an upgrade device configured to be removably connected to the upgradable multi-functional display device and comprising upgrade data configured to provide at least one additional function to the upgradable multi-functional display device;
a broadcast receiver configured for receiving a broadcast signal;
a demultiplexer configured for demultiplexing the received broadcast signal;
a decoder configured for decoding the demultiplexed broadcast signal;
a display configured for displaying the decoded broadcast signal;
an external device interface configured for receiving the upgrade data from the upgrade device;
a controller configured to
process the received broadcast signal for display on the display, and
upgrade at least one of firmware, hardware, or software of the upgradable multi-functional display device using the upgrade data received from the upgrade device, and
a control module configured to assign control authority for executing a function so that the upgrade device and the controller cooperatively execute the function, wherein the control module is configured to
when the function to be executed is the at least, one additional function provided by the upgrade data of the upgrade device, assign control authority to the upgrade device to control the upgradable multi-functional display device and assign the controller to support the upgrade device such that the additional function is executed in the upgrade device, and
when the function to be executed is a function other than the at least one additional function, assign control authority to the controller to control the upgradable multi-functional display device and assign the upgrade device to operate under the control of the controller.
2. The upgradable multi-functional display device of claim 1 , wherein the upgrade device is configured as a system on chip (SoC) or a dongle.
3. A method for controlling an upgradable multi-functional display device, the method comprising:
connecting an upgrade device configured to be removably connected to the upgradable multi-functional display device via an external device interface, the upgrade device comprising upgrade data configured to provide at least one additional function to the upgradable multi-functional display device;
detecting a connection of the upgrade device to the upgradable multi-functional display device;
receiving the upgrade data from the upgrade device;
upgrading at least one of firmware, hardware, or software of the upgradable multi-functional display device using the upgrade data received from the upgrade device based on the determination;
receiving a request for executing a prescribed function; and
assigning control authority for executing the requested function so that the upgrade device and the controller cooperatively execute the requested function, wherein assigning control authority comprises
when the function to be executed is the at least one additional function provided by the upgrade data of the upgrade device, assign control authority to the upgrade device to control the upgradable multi-functional display device and assign the controller to support the upgrade device such that the additional function is executed in the upgrade device, and
when the function to be executed is a function other than the at least one additional function, assign control authority to the controller to control the upgradable multi-functional display device and assign the upgrade device to operate under the control of the controller.
4. The method of claim 3 , wherein upgrading the upgradable multi-functional display device includes storing scheduling data including assigning the control authority of the upgrade device and the controller for a plurality of functions of the display device in a memory of the upgradable multi-functional display device.
5. The method of claim 3 , wherein the upgrading of the upgradable multi-functional display device using the device comprises upgrading the upgradable multi-functional display device using upgrade data received from the device through at least one of a universal serial bus (USB), a high definition multimedia interface (HDMI) and a peripheral component interconnect (PCI).
6. The method of claim 3 , wherein the upgrade device is configured as a system-on-chip (SoC) or a dongle.
7. The upgradable multi-functional display device of claim 1 , further comprising a memory configured for storing scheduling data including the assignment of control authority of the upgrade device and the controller for a plurality of functions.
8. The upgradable multi-functional display device of claim 1 , wherein the upgrading of the upgradable multi-functional display device using the upgrade device comprises upgrading the upgradable multi-functional display device using upgrade data received from the device through at least one of a universal serial bus (USB), a high definition multimedia interface (HDMI) and a peripheral component interconnect (PCI).
9. The upgradable multi-functional display device of claim 1 , wherein the upgrade device includes at least one content for implementing functions on the upgradable display device, control data for controlling the upgradable display device, or graphic data.
