The overall process of watching TV or watching recorded broadcasts with an external personal communication device is as shown in FIG. 4.

First, an external communication device attempts to connect to a communication device connected to a TV (S401).

Here, the communication device connected to the TV may be a device having a function of enabling the video service of the present invention and a general telephone function, or may be an independent device for video service only.

When the connection with the communication device connected to the TV is made, it is determined whether to watch the currently broadcast program or the recorded program (S402).

If the current broadcast program is viewed, the broadcast channel and the program to be selected are selected from the displayed broadcast list (S404).

If the program is not currently being broadcast and the recorded program is being viewed, if a recording list is displayed (S406), a program to be watched is selected from the corresponding list (S407).

Here, the recorded program may be a broadcast program received and stored in a TV system, or may be an image captured and stored using a camera of a personal communication device.

In this way, when the selection of the program to be watched is completed, the viewing time is set (S408).

If the viewing time is current (S409), the selected program is transmitted to the external communication device (S410).

If the viewing time ends while watching the transmitted program on the external communication device (S411), the transmission and viewing of the program is terminated and the connection with the external communication device is terminated (S413).

If the viewing time is not current, the viewing reservation is set (S412) and the connection with the external communication device is terminated.

The operation in the case of watching a program at the time of viewing reservation is as follows.

As shown in FIG. 5, when a reserved viewing time arrives (S501), an attempt is made to connect from a communication device connected to the TV to an external communication device (S502).

When the connection with the external communication device is established, the reserved program is transmitted to the external communication device (S503).

If the viewing time ends while watching the transmitted program on the external communication device (S504), the transmission and viewing of the program is terminated and the connection with the external communication device is terminated (S505).

In this way, an external communication device can be used to watch a broadcast transmitted from a TV.

Such a video service device and method of a TV system using a personal communication device according to the present invention can naturally search and control the state of a TV system in addition to a recorded broadcast program and a viewing function of a currently received broadcast program.

In addition, a function of monitoring the display of the parental control program according to age may be implemented by using a personal communication device from the outside.

That is, the reserved viewing of FIG. 5 may be set in a child viewing time zone, or a function of allowing a parent to try to connect from the outside to check a program currently viewed at home and take appropriate measures.

Such a video service device and method of a TV system using a personal communication device according to the present invention have the following effects.

The present invention transmits a broadcast program to an external personal communication device using a communication device connected to a TV, so that a broadcast can be watched without a portable TV from the outside.

In addition, an individual recorded broadcast can be connected to a TV from an external source and can be reproduced, or a user can store and play back images captured using a camera of a personal communication device.

It is possible to monitor the viewing program from the outside by using a personal communication device, and to check the status of the TV system and control various functions, thereby improving the applicability to various needs of the user.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention.
