4 and 5 illustrate two examples of an advertisement screen to be transmitted in the screen transmission method and apparatus including the image according to the present invention. First, a background in which the communication network operator 30 includes an advertisement to the subscriber 10 is described. In the step 111 of providing a screen, the screen is divided into a method of using the entire screen of the terminal 60 and a method of using the liquid crystal space 70 except for the center of the screen of the terminal 60. .

As described above, in the former case, the entire rear screen of a technically focused person may be used as an advertisement screen, and in the latter case, a rectangular liquid crystal space excluding the center of the screen may be used as an advertisement screen. In this case, there is a method of reducing the liquid crystal, or filling a certain portion of the liquid crystal, up or down, left and right, and the entire rectangular square border with an advertisement. In addition, the former uses all the background screens behind the moving center figure as an advertisement, which has the advantage of not exposing the user's own space or location that the subscriber does not want to see. It is provided with a device that can return to.

Looking at the implementation process of the present invention with reference to the accompanying drawings,

The video format currently being serviced on the Internet is Microsoft's ASW (AVI) format, but in mobile video communication such as IMT2000, it is H.263 based video that is currently applied on PSTN (or general telephone network), or The MPEG-4 based video format is expected to be used when the international standard is being completed. Therefore, in this proposal, the video format is based on the environment based on H.263 or MPEG-4.

1) MPEG-4 based video:

MPEG-4 is an international video compression standard established for multimedia communication of 64Kbps or less. In the MPEG-4 based video communication, the video compression and restoration process does not cover the entire screen, but instead compresses and restores the data in object units (compressed in VOP (Video Object Plane) units). In the encoder stage, the separated central object (person) is transmitted as it is compressed. Therefore, the problem of replacing the background screen with the advertisement screen is a problem of replacing only the background screen among the already compressed images for each object, and can be transmitted in real time by the mobile communication company instead of the terminal. For this purpose, the terminal simply needs to have a function of encoding in the MPEG-4 standard, that is, a function of separating and transmitting the central object from the screen in real time.

2) H.263 based video:

H.263 is a standard designed for video phones below 64Kbps. Unlike MPEG-4, the object of compression is not an object but an entire frame. Therefore, in order to have the function to be implemented in the present invention, a separate device having a function of separating and synthesizing the screen in the terminal other than the H.263 compression encoder (Encoder) is required. In other words, in this case, in order for the synthesis of the advertisement screen to be performed by the mobile carrier, the background is separated from the screen by decoding the transmitted simple H.263 compressed video, and the prepared advertisement background is inserted into the separated screen again. Encoding is required, but it is technically problematic that this series of operations are performed in real time. Therefore, in this case, a method of inserting an advertisement background image in the terminal will be adopted.

Therefore, in order to implement such an advertisement, element technology for developing a terminal as follows is required.

o Separation of central object: The segmentation of the central object is a method of finding and dividing the boundary of an object appearing on the image.

-How to make the right video

a) How to make a background with a specific color (Chroma Key Separation): How to make the background easy to distinguish by making the background a specific color with the special operation of the camera.

b) How to use the image of the thermal sensor: How to use this information by mounting a temperature sensor that clearly shows the outline of the object, rather than a normal CCD camera

-How to separate the central object from the captured image:

a) Split & merge method among image analysis techniques:

Once the captured images are separated by regions with certain conditions, in some cases, there are parts that are needed and parts that are not needed to represent an object, and these are combined and separated as needed. How to get.

b) watershed way:

As with the above method, one of the methods of merging the areas is to use the principle that when the water is filled, the small pools overflow and merge into a large pool. Among them, real-time accurate object separation is achieved by using special conditions of mobile communication, for example, always having a certain type of object in the center.

o Background screen preparation: In order to insert a real time advertisement in the terminal, the background in which the advertisement is inserted must be stored in the terminal and must be processed and inserted when communicating. Therefore, the advertisement screen can be stored in the terminal and downloaded and stored by the mobile network operator to a subscriber who has agreed at a certain time.

For example, if the subscriber inserts an advertisement screen, and the subscriber agrees to provide the advertisement of the network operator to protect his privacy and save the communication cost, each time the terminal is turned on (satellite time is transmitted to the terminal to display the current time) The wallpaper with the advertisement inserted can be automatically downloaded to the terminal. In addition, these wallpapers can be downloaded from time to time by selecting from the background provided by the service company when you want. Therefore, the service company prepares various types of wallpaper and overlays the advertisement contents received from the advertiser on the wallpaper desired by the subscriber to download the encoded signal to the individual terminal.

o Synthesis function: The terminal shall transmit the background screen including the downloaded advertisement by combining with the existing separated central object. Therefore, the terminal has the following functions.

-Memory and function to download wallpaper by connecting with service company

-The function of mixing and combining the synthesized background image with the existing separated central object: Since H.263 is encoded by frame unit, it is possible to download the separated and encoded background image from the beginning like MPEG-4. It simply downloads the full screen in the compressed form and inserts the advertised background in the compressed form.

As described above, the present invention configured as described above includes a network operator, an advertisement service provider, an advertisement company, a subscriber, and a communicator as described above in the screen transmission method and apparatus including an image; The subscriber requests communication to the network operator, the network provider provides the subscriber with a background including advertisements, the network operator connects the subscriber to the operator, and the subscriber applies for the service to the advertisement service provider. And the step of compensating the lowering fee to the network service provider by the advertising service provider and the step of requesting the advertising service from the advertising service provider to the advertising service provider, so that the entire rear screen of the technically focused person may be used as the advertising screen. It uses the liquid crystal space of the square except the center of the screen as the advertisement screen, and uses all the background screens behind the moving center figure as the advertisement, so that the subscriber can not expose his or her space or location that the subscriber does not want to see. LCD screen as much as the original size It produces the effect to be used.
