DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

0044Hereinafter, exemplary embodiments of the present invention will be described with reference to accompanying drawings, wherein like numerals refer to like elements and repetitive descriptions will be avoided as necessary.

0045<figref idref="f0001">FIG. 1</figref> illustrates the various components of a remote controller according to an exemplary embodiment of the present invention. As shown therein, the remote controller 100 may connect to a docking station 200 and may control an external device 300.

0046The remote controller 100 may receive information from an external network, such as the Internet 400. The information received by the remote controller 100 could include multimedia content. As discussed herein, the term "multimedia content" includes, but is not limited to, text, audio, still images, animation, video, and interactivity content forms, electronic program guide (EPG) content from a content provider, electronic messages received from users, information relating to current events, etc. Multimedia content can be transmitted to the remote controller 100 from remote databases or websites such as Flickr^©, Picasa^©, Facebook^©, etc. The information relating to current events could include information such as news, weather and/or financial information, such as stock prices and other market data.

0047Additionally, as shown in <figref idref="f0001">FIG. 1</figref>, the communication with the Internet 400 and the external memory 500 can be bi-directional. That is, the remote controller 100 may be operable to both receive data from and transmit data to the Internet 400 and the external memory 500. For example, the remote controller 100 may be operable to respond to alerts received from the Internet 400, or to move multimedia content from the Internet 400 to the internal 101 or external memory 500 (or vice versa). Likewise, the remote controller 100 may send data to and receive data from the external device 300.

0048The external device 300 may include a video display such as a television or monitor. Alternatively, the external device may include a device which outputs audio and/or video, such as a set-top box, stereo, an iPod^© or other MP3 players, a CD or DVD player/recorder, a video game console such as Sony PlayStation^©, Nintendo Wii^© or Microsoft Xbox^©. However, the general inventive concept is not limited to these types of external devices. The exemplary embodiments described herein can generally apply to any electronic appliance or device capable of being controlled with a remote controller.

0049In addition to receiving multimedia content from the Internet 400, the remote controller 100 may receive multimedia content from an external memory 500 and/or an internal memory 101 (shown in <figref idref="f0003">FIG. 3</figref>). An internal memory 101 could include, but is not limited to, a computer memory such as random access memory (RAM), flash memory, read only memory (ROM), etc. Likewise, an external memory 500 could include, but is not limited to, hard disk drives (HDDs), compact discs (CD) ROM, memory cards, universal serial bus (USB) flash drives, etc.

0050<figref idref="f0002">FIG. 2A</figref> shows an example of an internal display screen 102 of a remote controller 100 according to an exemplary embodiment of the present invention. The internal display screen 102 can be a touchscreen-type display which can detect the presence and location of a touch within the display area of internal display screen 102. Further, the internal display screen 102 can also utilize multi-touch technology. However, the internal display screen 102 does not necessarily have to be a touchscreen-type, and the remote controller 100 can instead utilize other means for receiving input from a user, such as with a keypad or other controlling mechanisms.

0051<figref idref="f0002">FIG. 2B</figref> shows an example of a remote controller 100 connected to a docking station 200 according to an exemplary embodiment of the present invention. The docking station can be produced from a variety of materials and can be formed in a variety of shapes and orientations. As shown in the example shown in <figref idref="f0002">FIG. 2B</figref>, the docking station 200 can connect to and hold the remote controller 100 in an upright, or picture frame-type manner so that the internal display screen 102 to be easily visible by a user.

0052Furthermore, as shown in the example shown in <figref idref="f0002">FIG. 2B</figref>, the docking station 200 can be connected to a power source 210. Thus, power source 210 could provide operating and/or charging power to the remote controller 100 via the docking station 200. To accommodate a charging function, the remote controller 100 could include a battery (shown in <figref idref="f0003">FIG. 3</figref>). Alternatively, the power source 210 need not provide operating and/or charging power to the remote controller 100 only via the docking station 200. For example, the power source 210 might directly connect to the remote controller 100.

0053The remote controller 100 could detect a connection to the docking station 200, and begin charging automatically upon detecting such connection. Further, the remote controller 100 could detect the presence or absence of a connection to the docking station 200 based on either an electrical or a mechanical mechanism. For example, the remote controller 100 could include an electrical connector (not shown) which connects to an electrical connector on the docking station 200. Upon making a connection with the docking station 200, an electrical signal could be sent from the power source 210 to the docking station 200, and to the remote controller 100 via the respective connectors. Alternatively, the remote controller 100 might employ a mechanical type mechanism which, when connected to the docking station 200, would switch in such a way as to indicate the presence or absence of the connection to the docking station 200.

0054As shown in <figref idref="f0003">FIG. 3</figref>, the remote controller 100 can include an internal memory 101 and a battery 103 (as noted above), a network module 104, a transceiver unit 105 and a controller 106.

0055As noted above, the internal memory 101 may include different types of memory, and can store multimedia content utilized by the remote controller 100. The battery 103 could be used to store charge to supply operating power for the remote controller 100 when not plugged into a power source 210, such as may be provided via the docking station 200. The network module 104 can facilitate communication with an external network such as the Internet 400 or a local area network (not shown). The transceiver unit 105 could likewise facilitate communication with the external device 300. For example, the remote controller 100 could transmit control commands from the remote controller 100 to the external device 300 through the transceiver unit 105. Similarly, the transceiver unit 105 could also be operable to receive signals from the external device 300. For example, control of some external devices might require two-way communication with the remote controller 100. Finally, the controller 106 can be utilized so as to control the overall functioning of remote controller 100, including the interaction between all of the above noted components.

0056According to an exemplary embodiment of the present invention, the remote controller 100 is operable to be in a first or a second operating mode. As an example of a first operating mode, the remote controller 100 could provide multimedia content. For example, the remote controller 100 might display a video or play audio while in the first operating mode. Such a first operating mode might be referred to as a "content providing mode."

0057By contrast, in a second operating mode, the remote controller 100 could display on the internal display screen 102 a control panel for controlling the external device 300, or an EPG screen relating to programming received from the Internet 400, for example. Such a first operating mode might be referred to as a "control mode."

0058It should be noted that the general inventive concept of the present invention is not limited to operating in only a first and second mode. Multiple operating modes may be utilized.

0059<figref idref="f0004">FIG. 4</figref> is a flowchart showing a basic operation of an exemplary embodiment of the present invention. In operation S401, the controller 106 determines whether the remote controller 100 is connected to the docking station 200. If a connection to the docking station 200 is determined to exist (S401-Y), in operation S402 the controller 106 determines whether the remote controller 100 is in the second operating mode. If it is determined the remote controller 100 is not in the second mode (S402-N), the process ends. On the other hand, if the controller 106 determines the remote controller 100 is in the second operating mode (S402-Y), the controller 106 controls the remote controller 100 to change to the first mode.

0060<figref idref="f0005">FIG. 5</figref> is a flowchart showing another basic operation of an exemplary embodiment of the present invention. Whenever the controller 106 determines the remote controller 100 is in the second mode and connected to the docking station 200 (S501-Y), the controller 106 then controls the remote controller 100 to change to the first mode and suspend displaying an initial image which may be displayed on the internal display screen 102 (S502). The controller 106 then controls the remote controller 100 to begin providing multimedia content (S503). If during the providing the multimedia content (S503), the controller 106 senses user input to the remote controller 100 (S504-Y), the controller 106 then controls the remote controller 100 to suspend providing the multimedia content (S505).

0061As noted above, the internal display screen could include a touchscreen which receives user input, or the remote controller 100 might include a keypad or other controlling mechanisms for receiving user input.

0062<figref idref="f0006">FIG. 6</figref> is a flowchart showing another basic operation of an exemplary embodiment of the present invention. In operation S601, the controller 106 determines whether the remote controller 100 has been removed from the docking station 200. If the remote controller 100 has been removed from the docking station 200 (S601-Y), the controller 106 controls the remote controller 100 to change to the second mode, and suspend providing multimedia content (S602), and then to resume displaying the initial image (S603).

0063<figref idref="f0006">FIG. 7</figref> is a flowchart showing another basic operation of an exemplary embodiment of the present invention. If the remote controller 100 is in one of the first and second operating modes, the remote controller 100 is operable to receive an alert including at least one of an electronic program guide (EPG) alert related to an upcoming show, an electronic message received from a user, and information relating to at least one of least news, finance and weather, wherein if the alert is received, the controller 106 controls the remote controller 100 to display the alert on a portion of the internal display screen 102.

0064As noted above, an exemplary embodiment of the present invention includes two different operating modes, a content providing mode, and a control mode. As suggested above, the remote controller 100 might display a video or play audio while in the content providing mode. Similarly, as suggested above, the remote controller 100 might display on the internal display screen 102 a control panel for controlling the external device 300, or an EPG screen relating to programming received from the Internet 400 while in the control mode.

0065However, the operation in each mode does not have to be limited to displaying only one type of information. That is, the remote controller 100 might operate in multifunctional operating modes. For example, while in the content providing mode, the remote controller 100 might display multimedia content in a substantial portion of the internal display screen, and simultaneously display information which might be shown in the control mode (e.g., a control panel for controlling the external device 300, or an EPG screen relating to programming received from the Internet 400) in a smaller portion of the internal display screen.

0066Similarly, while in the control mode, the remote controller 100 might display a control panel for controlling the external device 300, or an EPG screen relating to programming received from the Internet 400, in a substantial portion of the internal display screen, and simultaneously display information which might be shown in the content providing mode (e.g., multimedia content) in a smaller portion of the internal display screen.

0067<figref idref="f0007">FIGS. 8A and 8B</figref> show examples of these types of multifunctional operating modes according to exemplary embodiments of the present invention. As shown in <figref idref="f0007">FIG. 8A</figref>, while the remote controller 100 is operating in a control mode, a control panel for controlling the external device 300 is displayed on a larger portion 107 of the internal display screen 102. At the same time, multimedia content is displayed on a smaller portion 108 of the internal display screen 102.

0068Likewise, as shown in <figref idref="f0007">FIG. 8B</figref>, while the remote controller 100 is operating in a content providing mode, multimedia content is displayed on a larger portion 107 of the internal display screen 102. At the same time, EPG information is displayed on a smaller portion 108 of the internal display screen 102.

0069Additionally, the predetermined multimedia content may include different types of content. As such, the controller 106 may control the remote controller 100 to change to the first operating mode, whereby each of the different types of content are provided in a cyclical format. Moreover, a predetermined priority may be selected for each of the different types of content, such that each of the different types of content are provided in the cyclical format according to the respective predetermined priorities selected for the different types of content.

0070Hereinbelow, another exemplary embodiment of the present invention will be explained in detail with reference to <figref idref="f0008">FIG. 9. FIG. 9</figref> illustrates a flowchart of the operations of controlling a remote controller according to another exemplary embodiment of the present invention.

0071As shown in <figref idref="f0008">FIG. 9</figref>, if a user inputs a command to play back a still image (S901-Y), the controller 106 controls the remote controller 100 to operate in a still image playback mode (S902, S903).

0072In the still image playback mode, the controller 106 controls the remote controller 100 so that a still image is displayed on the internal display screen 102 (S902), and it is determined that a predetermined time has elapsed while a user does not operate the remote controller 100 (S903).

0073The predetermined time in operation S903 may be set appropriately as occasion demands.

0074The still image may be typified as a picture content, but a text content, an EPG screen, a screen for controlling an external device, an Internet browser, a file browser, and other screens for executing application programs may also have the characteristic of the still image. Accordingly, if a user inputs a command to call for/execute the screen having the characteristic of the still image, the command may be treated as the same case as in operation S901, that is, a user inputs the command to play back a still image.If it is determined that a predetermined time has elapsed while a user does not manipulate the remote controller 100 (S903-Y), the controller 106 determines whether the remote controller 100 is connected to the docking station 200 or not (S904).

0075If it is determined that the remote controller 100 is connected to the docking station 200 (S904-Y), the controller 106 controls the remote controller 100 to operate in a screen saver mode (S905).

0076In the screen saver mode, the controller 106 controls the remote controller 100 to display a screensaver instead of the still image on the internal display screen 102. The screensaver may be formed as an icon such as a character, clock, or calendar against a dark background. The character, clock, or calendar displayed on the screensaver may be selected by a user according to a user's preference.

0077If a user inputs a command to wake up a screen (S906-Y), the controller 106 returns to operation S902. The command to wake up a screen in operation S906 may be input by touching the internal display screen 102 of the remote controller 100 or pressing manipulation buttons by a user.

0078If it is determined that the remote controller 100 is not connected to the docking station 200 (S904-N), the controller 106 controls the remote controller 100 to operate in a power save mode (S907).

0079In the power save mode, the controller 106 controls the elements constituting the remote controller 100 to consume the minimum power. As the power is not supplied to the internal display screen 102 in the power save mode, the internal display screen 102 displays a black screen.

0080If a user inputs a command to wake up a screen (S908-Y), the power is re-supplied to the elements constituting the remote controller 100 under the control of the controller 106 (S909). The controller 106 returns to operation S902.

0081If a user inputs a command to play back a moving image (S910-Y), the controller 106 controls the remote controller 100 to operate in a moving image playback mode (S911).

0082The moving image playback mode is similar to the still image playback mode, in that the controller 106 controls the remote controller 100 so that a moving image is displayed on the internal display screen 102. However, the moving image playback mode is different from the still image operation mode, in that the controller 106 performs neither the operation of determining a predetermined time has elapsed while a user does not operate the remote controller 100 nor the following operation.

0083The controller 106 determines whether the remote controller 100 is connected to the docking station 200 or not in operation S904, but the case that the remote controller 100 is directly connected to the power source 210 may also be regarded as satisfying operation S904.

Also, the description of the exemplary embodiments of the present invention is intended to be illustrative, and not to limit the scope of the claims, and many alternatives, modifications, and variations will be apparent to those skilled in the art.
