First Embodiment

If a program reservation is requested in the state that the program information necessary for watching TV in real time, the electronic device 100 may register the program as a scheduled item in association with the schedule application (e.g. S planer) and VOD (On Demand). Typically, the video display device is capable of navigating broadcast programs using the broadcast program information (Electronic Program Guide (EPG)). The video display device is also capable of making it possible to watch the programs already aired using rebroadcast informations or VOD informations. In the following description, the terms ‘broadcast program’ and ‘program’ are interchangeably used in the same meaning; and the terms ‘program information’, information of program’, and ‘EPG’ are used interchangeably in the same meaning. The electronic device 100 may provide the information in association with the schedule application and EPG and/or VOD in real time.

The program information provision method may be executed manually or automatically. In the manual broadcast program registration method, the control unit 300 of the electronic device 100 may download the program information from the broadcast server 120 and store in the storage unit 310 and control the display unit 330 to display the program information. The program information may include the information (including broadcast date) on the programs to be broadcast (or rebroadcast) by the broadcast station (including cable and IP TV providers). If the user select a certain program information item by means of the input unit 340 in the state that the display unit 330 displays the program information, the control unit 300 executes the schedule application which checks the broadcast date (or rebroadcast date) included in the program information and registers the program as a scheduled item with a calendar (such as S-planer). In the case of the pay program, it is possible to register the program, after the program has been purchased, as a scheduled item with the scheduler application along with the playback time.

The electronic device 100 also may register the broadcast program automatically based on the program information provided by the broadcast server 120. The control unit 300 of the electronic device 100 may transmit the information on the program registered as a scheduled item to the broadcast server 120 by means of the first communication unit 320. The processor 200 of the broadcast server 120 stores the information on the program registered with the electronic device 100 as the schedule item. If the program information is received, the processor 200 may analyze the accumulated program information to check the user's favorite programs, select the program information closely associated with the received program information, and send the selected program information to the electronic device 100. The control unit 300 registers the user favorite broadcast and content information with ‘my schedule’ automatically.

If the program information is downloaded from the broadcast server, the control unit 300 may register the information on the programs associated with the program scheduled by the user with the schedule and alarms automatically. If there is the related broadcast program registered on the same date, the control unit 300 may notify the user of the related broadcast program so as to set the schedule-registered time in consideration of the program running time or broadcast time.

As described above, a program may be registered as a scheduled item by the user manually or by the broadcast server 120 automatically such that the program is played at the time registered in the schedule. If the registered time arrives, the control unit 300 may notify the user of arrival of the registered time by means of the display unit 330 and/or the audio processing unit and turns on the external display device 190 through the second communication unit 370 in response to the user request. The external display device 190 may receive and display the program registered in the schedule under the control of the control unit 300.

The external display device 190 and the electronic device 100 may communication through a wireless link. If brief, if scheduled time of the registered program arrives, the control unit 300 may establish a communication link with the external display device 190 and, if the communication is established normally, determine this as the playback-available state at operation 915 and thus transmit the channel information on the program registered as a scheduled item so as to play the program at operation 917. However, if at operation 915, the control unit fails to establish the communication link with the external display device 190, the control unit 300 may determine this as the playback-unavailable state and determine whether a predetermined time duration for determining as a missing program has elapsed at operation 921. If the scheduled time arrives, the control unit 300 may establish a communication link with the external display device 190 and, if the control unit 300 fails to establish the communication link, the control unit 300 may retry communication establishment repeatedly for a predetermined duration. If the predetermined time elapses, the control unit 300 may determine that a missing program has occurred at operation 921 and handles the corresponding program as a missing program at operation 923.

If the missing program occurs, the control unit 300 analyzes the corresponding program information to check whether there is any rebroadcast schedule of the program and, if so, executes the schedule application to register the program at the rebroadcast time with the calendar at operation 923. Otherwise, there is not rebroadcast schedule, the control unit 300 may cancel the registration of the corresponding broadcast program at operation 923.

The electronic device 100 may include a broadcast receiver 350. In this case, if it is impossible to establish a communication link with the external display device 190 at the scheduled time, the control unit 300 may play the registered program with the broadcast receiver 350. That is, if it is impossible to play the program using the external display device 190, the control unit 300 may check the playback availability with the broadcast receiver 350 at operation 915 and activate the broadcast receiver 350 to play the corresponding program through the display unit 330 at operation 917.

After registering the program as a scheduled item, if the schedule time arrives, the electronic device 100 may play the registered program through the external display device 190. In the state that the external display device 190 is playing a certain broadcast program, the electronic device 100 may display other video or information associated with the broadcast program being played on the external display device 190 simultaneously.
