Many of these multimedia content reproduction apparatuses provide a remote controller for remote control to be performed through the transmission of a radio control frequency for the convenience of the user.

In general, the remote control is a tool necessary for remotely operating home appliances such as a television receiver and a set top box, and is used to remotely operate a multimedia content reproducing apparatus such as the television or the set top box without direct manipulation. The remote controller includes a transmitter on the remote controller and a receiver on the receiver side of the multimedia content reproducing apparatus. The remote controller is connected via a short-range communication means such as infrared or ultrasonic waves as a transmission medium to transfer any operation information between the transmitter and the receiver. . That is, the remote control modulates the user's key operation into an electric signal and loads it on a transmission medium such as infrared rays, and the receiving unit on the multimedia content reproducing apparatus demodulates the operation signal by demodulating the electric signal using the transmission medium transmitted from the remote control. If the control unit is sent to the control unit, the control unit performs a specified operation on each device.

With the development of technology, the multimedia content reproduction apparatus as described above has realized more various functions. In particular, as with a recent smart TV, not only multimedia contents can be played but also related information can be directly searched using an internet network, and related information can be provided directly from a broadcast program, thereby selectively receiving information.

However, in order to control the various functions as described above with the remote controller, the key buttons of the remote controller become more and more complicated, and the user may not easily understand the function of the specific key button. When a large number of key buttons are required and a plurality of functions are integrated into one key button to implement a remote controller more consequently, there is a problem in that the function of the corresponding key button can not be intuitively recognized. Although a description of the function may be briefly displayed around the key button, the detailed description is not possible and there is a problem that the lighting of the room must be maintained even when watching a movie.

It is determined whether the signal receiver 200 receives the first signal or the second signal (S130), and when the signal receiver 200 receives the first signal, a UI (User Interface) message UI of message 412 such as output device 300 guides' search 'button corresponding to the function of the' search 'button 110 corresponding to the finger position-click to connect to the search window.' It is displayed on the screen 410 connected to the message output device 300 (S140).

When the signal receiver 200 receives the second signal, the UI (User Interface) message output device 300 displays a search window 413 corresponding to the function of the “search” button 110. It is displayed on the screen 410 connected to 300 and receives a search word (S150).

9 is a flowchart illustrating a case where a signal corresponding to a "change channel" button is received according to another embodiment of the present invention. The key button is a channel change button 110, and the related additional information is content received in a channel selected when the channel change button is operated. When the UI message output device 300 receives the first signal, the channel change button The content received from the channel selected during operation of the 110 may be reproduced on the sub-screen 416 provided on a part of the screen 410 connected to the UI message output device 300. In addition, when the signal generator 100 detects a finger position on the channel change button 110, the UI message output device 300 may receive a content stream received from a channel selected when the channel change button 110 is operated. The method may further include transmitting a buffering start signal to the signal receiver 200 instructing to start buffering.

5A, 5B, and 9, when the user places a finger on the "change channel" button 110 of the signal generator 100, the sensor 120 of the signal generator 100 Measures the finger position on the "change channel" button 110 of the signal generator 100 (S210).

When the sensor 120 of the signal generator 100 measures the finger position, the signal receiver 200 receives a first signal including the finger position information from the signal generator 100, and the user receives the signal. When the "channel change" button 110 of the generator 100 is operated, the signal receiver 200 receives a second signal including operation information of the "channel change" button 110 from the signal generator 100. (S220).

It is determined whether the signal receiver 200 receives the first signal or the second signal (S130), and when the signal receiver 200 receives the first signal, the signal generator 100 Transmits a buffering start signal to the signal receiver 200 instructing the UI message output device 300 to start buffering the content stream received on the channel selected when the “change channel” button 110 is operated. (S240).

In addition, the UI (User Interface) message output device 300 is the additional information corresponding to the function of the "channel" button 110 corresponding to the position of the finger, it is selected when the "change channel" button 110 is operated Content received from the channel can be played on the sub-screen 416 provided on a part of the screen 410 connected to the UI message output device (S250).

When the signal receiver 200 receives the second signal, the UI (User Interface) message output device 300 changes a channel as a function corresponding to the “change channel” button 110 and the UI message output device 300. In step S260, content received through the changed channel may be displayed on the main screen 415 of the screen 410 connected to the screen.

Specific features of the content playback method according to an embodiment of the present invention are as described in the above-mentioned content playback system.
