 DETAILED DESCRIPTION OF THE INVENTION

Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

FIG. 1 is a block diagram of an image transmission system according to an embodiment of the present invention.

Referring to FIG. 1, the image transmission system is constructed to include a user's uploading unit 100, a broadcast station's server 200, and a recipient's display device 400. Here, examples of the recipient's display device 400 include a TV receiver. The uploading unit 100 transmits at least one of an image, a voice and a message, together with reservation request information, to the server 200. The reservation request information includes user information, recipient information, the type of an image to be uploaded, a reserved broadcast date and time, and display options, and so on. The user information includes the user's name, address, phone number and e-mail address, and the like. The recipient information includes the number of recipients, the recipients' names, addresses, phone numbers, e-mail addresses and display device identification (ID) or Internet protocol (IP) addresses, and so on. Also, the reservation request information may further include a message to be displayed together with the image. Examples of the uploading unit 100 include a mobile terminal, such as a portable phone and a PDA, a digital TV, a camcorder and a PC.

The server 200 stores the image, the voice and the reservation request information that are received from the uploading unit 100, and transmits the image, the voice and the message to the recipient's display device 400 according to the reservation request information. The server 200 is constructed to include a controller 201 for controlling input and output of various data, and a database (DB) 202 or a memory for storing the data.

FIG. 2 is a flow diagram illustrating an image transmission method according to an embodiment of the present invention.

The image transmission method will now be described with reference to FIG. 2.

Referring to FIG. 2, the image transmission method is broadly classified into three steps. That is, the image transmission method is constructed to include the steps of: transmitting an image, a voice and a message, together with reservation request information, to the server 200 (S100); storing the image, the voice, the message and the reservation request information (S200); and transmitting the image, the voice and the message to a corresponding recipient according to the reservation request information (S300).

FIG. 3 is a flow diagram illustrating a procedure for transmitting an image, a voice and message to the server 200.

The procedure for transmitting an image, a voice and message will now be described in detail with reference FIG. 3.

Referring to FIG. 3, when a user connects the uploading unit 100 to the server 200 through a communication network such as the Internet (S101), the server 200 provides a menu for registering or selecting reservation request information to the user. The user generates reservation request information by using the menu displayed on the uploading unit 100.

The user registers the type of image to be uploaded, a desired broadcast date and time, and display options by using the menu (S102). The image type represents whether the image is an MPEG (moving picture experts group) image or a digital video (DV) image. The user registers his user information (S103), and selects a recipient (S104). For example, the user registers the number of recipients, the recipients' name, address, phone number, e-mail addresses and display device ID or IP addresses (S105). Also, the user can register a message to be displayed together with the image, by using the menu (S106 and S107).

The server 200 determines whether to be able to transmit the image at the date and time reserved by the user, and transmits the determination results to the uploading unit 100. If transmission of the image can be reserved, the uploading unit 100 uploads the image and the voice to the server 200 (S108). The server then stores the reservation request information and the uploaded image and voice.

FIG. 4 is a flow diagram illustrating a reserved image-processing method according to an embodiment of the present invention.

The reserved image-processing method will now be described in detail with reference to FIG. 4.

Referring to FIG. 4, the server 200 determines whether or not an image reserved by a user exists from the stored reservation request information (S201). The server 200 then determines whether or not the reserved image is suitable for the over-the-air broadcast (S202 and S203). For example, the server determines whether or not the reserved image or voice contains a lewd or violent content. For this determination, the server 200 may scan word data contained in the voice, or a broadcast station's staff may monitor the image and voice. If the reserved image is determined to be unsuitable for the over-the-air broadcast, the server 200 transmits to the uploading unit 100 a message for informing the unsuitableness of the image (S213).

If the reserved image is determined to be suitable for the over-the-air broadcast, the server 200 determines a broadcast date and time from the reservation request information corresponding to the reserved image (S204). The server 200 then transmits a message for informing the user of the determined (or reserved) broadcast date/time and a service fee to the uploading unit 100 or the user's mobile terminal or e-mail address (S205). Also, the server 200 transmits a message preannouncing the reservation transmission to the recipient 300's display device 400 or the recipient 300's mobile terminal or e-mail address (S206). Here, the message preannouncing the reservation transmission will be referred to as a preannouncing message. The preannouncing message includes the reserved broadcast date and time.

The server 200 stores the reserved image and voice in a DB corresponding to the reserved broadcast date and time (S207), and then transmits the stored image and voice to the display device 400 when the reserved broadcast date/time arrives (S208). If a stored message exists, the server 200 also transmits the stored message to the display device 400, together with the reserved image and voice.

If in a turned-on state, the display device 400 receives the reserved image and voice and then displays the received image and voice on its screen. At this time, the display device 400 displays the reserved and received image (hereinafter simply referred to as “the image”) on its sub-screen (S209), such as a PIP (picture in picture) screen, or on its main screen according to set display options. During the display of the image, the display device 400 determines whether or not a display screen mode switch command (hereinafter simply referred to as “the mode switch command”) is inputted thereto by the recipient (S210). If the mode switch command is inputted, the display device 400 displays the image on its sub-screen or main screen according to the mode switch command (S211). If the image is displayed while the recipient watches a broadcast program of a specific channel, a voice of the broadcast program is muted and the voice corresponding to the image is outputted.

If in a turned-off state, the display device 400 stores the received image and voice. Thereafter, when the recipient turns on the display device 400, the display device 400 displays on its screen a message for informing the recipient that the received image and voice has been stored therein.

The display device 400 generates a confirmation message for informing the server whether or not the recipient has watched the image, and then transmits the confirmation message to the server 200, For example, the display device 400 transmits to the server 200 a message for informing the server that the image has been displayed, Upon receipt of the confirmation message from the display device 400, the server 200 transmits the received confirmation message to the uploading unit 100.

As stated above, the system and method according to the present invention makes it possible to transmit a reserved image to a desired person on a broadcast wave and then display the resulting received image on the person's TV, and to transmit a reserved image to a predetermined recipient at a reserved date and time.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
