Referring to FIG. 3, the frame is a basic unit that constitutes a single video, and means a single picture in which several pictures or characters are expressed, and one video is displayed by transmitting and displaying such continuous frames. Will be constructed. The frame is composed of several picture types, and FIG. 3 shows that the first frame is composed of two picture types (first picture type data and second picture type data) and one character type. Since the letter type is sufficiently represented by the conventional art, only the picture type will be described in the present invention. The picture type may be classified into a basic picture type and a transition picture type, wherein the basic picture type is a picture type which is a basic picture type among the picture types constituting a video, and the transition picture type is a picture that is somewhat deformed from the basic picture type. Defined by type. In addition, the picture type represented in the frame is configured to have a unique ID, respectively, to use the ID to give information about the picture type included in the frame. The classification criteria of each picture type may be arbitrarily determined.

4 is a diagram illustrating a method of transmitting a basic picture type. Figure 4 (a) shows a basic picture type having a two-dimensional array consisting of eight pixels in nine longitudinal directions in the horizontal direction. As shown in (a) of FIG. 4, a basic picture type having a two-dimensional array is transmitted in units of consecutive bits or bytes. As shown in (b) of FIG. 4, the pixel values in the first horizontal line are sequentially In this case, the second pixel value is transmitted, and finally, the pixel value in the eighth row is transmitted. The first horizontal line is transmitted as "146 200 218 .... 146 85 146" as a byte value, and is transmitted through the wireless data network as "10010010 11001000 11011010 ..... 10010010 01010101 10010010" which is converted to binary number. do.

FIG. 5 is an explanatory diagram for explaining a portion having a pixel value different from the basic picture type in the transition picture type data. In general, the basic picture type is a picture type frequently used in a video and is generally determined by a video creator. Each picture type in the video to be transmitted is divided into a plurality of blocks, and each divided part is composed of blocks, and the basic picture type determined by the video producer and the picture type not determined are compared. The number of blocks is different from the number of blocks having the same pixel value. This means a picture type with a small number of blocks with pixel values. Statistically, the threshold is set to an integer that is rounded up or down of the calculation result of "(2/3) * total blocks", and the picture type data having the number of blocks above the threshold can be classified as a transition picture type data.

Figure 5 (a) shows a basic picture type of ID i, Figure 5 (b) shows a transition picture type of ID j. The basic picture type of ID i of FIG. 5 (a) and the transition picture type of ID j of FIG. 5 (b) are composed of 8 pixels in 9 vertical directions in the horizontal direction, and the number of blocks of the picture types is 20 It is composed of blocks, and each block contains four pixels. The block size can be arbitrarily selected by the video producer. By comparing the pixel values of the two picture type data with ID i and ID j, the blocks having different pixel values are identified as shown in FIG. Instead of transmitting the entire pixel value shown in FIG. 5 (b), the transition picture type with ID j transmits only blocks having a difference in pixel value from the basic picture type of ID i as shown in FIG. The transmission amount can be reduced.

FIG. 6 is a diagram illustrating a method of transmitting a block having a pixel value different from that of the basic picture type in the transition picture type. 6 (a) is composed of a total of 20 blocks, and indicates that the eighth block, the ninth block, the tenth block, and the sixteenth block among the configuration blocks have pixel values different from the basic picture type. If blocks having pixel values different from the basic picture type exist consecutively like the eighth block, the ninth block, and the tenth block, the blocks are regarded as one part and the "start block and end block number" are transmitted. As shown in 6 (b), the horizontal pixel values of the blocks designated as parts are first transmitted, and then the vertical pixel values are transmitted later. Consecutive blocks having pixel values different from the basic picture type are transmitted as parts, and non-contiguous independent blocks are transmitted in block units as shown in FIG.

7 is a structural diagram of video data used in a video transmission method using the present invention wireless communication. The video data is constructed and compressed in the content server shown in FIG. The content server uses the specifications of the mobile communication terminal and the information of the terminal user stored in the HLR shown in FIG. 2 to find out the specifications of the terminal, and then a bitmap of video data to be serviced according to the specifications (one pixel for each pixel). The image data is composed and the video is newly encoded according to the compression algorithm in the content server. Referring to FIG. 7, the video data includes an S.I.S header, a video information unit, a frame header, a moving data structure, a picture type header, and picture type data. Table 1a and Table 2a show the contents of the Simple Image Service (SIS) image header in the video data configured in the content server.

The SIS image header consists of a plurality of fields as shown in Table 1a and Table 1b. Referring to Table 1, the SIS image header will be described in detail in the S.I.S identification unit, the frame information unit, and the picture type information unit. The SIS identifier displays an Image Identifier field that indicates that the data is a movie, a Version field of the SIS that indicates whether the data is monochrome, gray, or color, an image size field that indicates the size of the data, and a movie. And a reversal field indicating whether or not the entire screen is inverted.

The frame information unit can express a video by selecting any number of frames of a part of a video to easily introduce the video, and a frame number field, a static frame number field used to designate one frame as a representative frame. Number of short frames, a frame duration field indicating an interval of time at which each frame is represented, a variable delay field for adjusting a time interval at which each frame is represented, if necessary, and how the images constituting the frames are stacked in some way The number of layers indicating whether the video is to be transmitted, the repeated flag field indicating whether the frame constituting the video is repeated, the used palette field, the compression field, the palette compression field, the palette size field, and the data field of the palette. do. In addition, the picture type information section includes a picture type level field, a compression method field, and a picture type number field.

Referring to Table 1, the S.I.S image header will be described in detail. The identifier field is composed of 3 bytes to represent the characters of S, I, and S. When the character is input, the data is SIS.

The SIS version is configured to overcome the limitation of the expression of the video of the mobile communication terminal according to the development of the video transmission technology, and indicates that the video is any one of the development stages of the technology, which can be decoded by the mobile communication terminal. This field is arbitrarily given to inform the version of the video so that it can be configured as a video suitable for the mobile communication terminal model.

The version field of SIS can be composed of 8 bits.The 8 bits are divided into two parts.The 1st to 3rd bits are divided into the least significant bits (LSBs), and the 4th to 8th bits are divided into the most significant bits (MSBs). It defines and uses the most significant bit and least significant bit to represent four different versions. The number of bits in the most significant bit and the least significant bit is specified randomly.

The Image Size field is a field indicating the size of the entire video data and indicates the size of the entire video file including 3 bytes of the image identifier.

The horizontal size field and the vertical size field are fields for indicating the size of the screen of the mobile communication terminal, and serve to make a video appropriately displayed on the screen of the mobile communication terminal. The horizontal size field and the vertical size field can be designated as 1 byte each, so that the width and height of the screen can be designated as 256 pixels, and can be expanded according to the version.

The inversion field is a field indicating whether data of the entire video is inverted.

In the frame number field, this field indicates the total number of frames required to express the video.

The number of still frames field may be configured by setting one field as a representative frame among all the fields of the video to indicate a frame that can represent the video in the form of an icon on the screen of the mobile communication terminal and may be configured as 1 byte. It is also possible to indicate when a freeze frame is used in the field and when a freeze frame is not used, indicating whether to use freeze frame using the eighth bit, the most significant bit in one byte, and the remaining seven bits The frame number used as the still frame is displayed. If the 8th bit, the most significant bit, is filled with 0, it indicates that the movie does not use a still frame, and the remaining 7 bits have no meaning. When the eighth bit is filled with 1, the frame uses a still frame, and the number of frames used as the still frame is expressed in the remaining seven bits. For example, the binary value 0001011 of the lower 7 bits displays 11 as decimal number and the frame number starts from 0, which means that the 12th frame is used as the still frame.

The simple frame number field is a field for editing a part of the entire video to display a frame representing the characteristics of the video rather than the entire video. The simple frame number field shows information on whether a simple frame is used and which frame is used as a simple frame. The short frame number field is composed of 1 byte, the most significant bit in 1 byte indicates whether to use a short frame, and the remaining 7 bits indicate how many frames the short frame is composed of. If the eighth bit, the most significant bit, is filled with 0, it indicates that no simple frame is used, and the remaining seven bits have no meaning. In addition, when the eighth bit is filled with 1, it indicates that a simple frame is used, and the remaining seven bits indicate the number of frames used. If the lower 7 bits are composed of 0000011, binary 0000011 is represented as 3 as decimal number and count starts from 0, so the total number of frames used as simple frame is 4 in total.

The frame duration field indicates how long each frame constituting the video is displayed on the screen of the mobile communication terminal when the video is displayed. When the frame duration field is set to 1 byte in size, the 8th bit, the most significant bit of the frame duration, indicates that each frame of the transmitted video is displayed for various times, and if the 8th bit is filled with 1, Frames are represented on the screen for different times. The remaining seven bits indicate the time each frame is displayed on the screen. If the 8th bit, the most significant bit, is filled with 0, the time for each frame to be displayed on the screen is determined according to the value of the lower 7 bits. When the lower seven bits are all filled with zeros, each frame representing the video is represented by each frame with a minimum time that can be arbitrarily determined. Table 1 shows the minimum time as 100ms. For example, if the eighth bit, which is the most significant bit, is 0 and the lower seven bits are filled with 0000101, the decimal value of 0000101 is 6 and the representation time of the screen is displayed on the screen in multiples of the minimum time. Thus, each frame is represented by a regular speed with a time of (100 ms) * (lower 7 bits of decimal value + 1). If the eighth bit is 1, a variable delay field exists, and each frame is displayed at a variable time on a screen of the mobile communication terminal. The lower seven bits are meaningless.

The variable delay field is present only when the eighth bit, the most significant bit of the frame duration field, is filled with one. In expressing a video, when the frames constituting the video need to be represented for various times, the presentation time of all the frames constituting the video is displayed in each byte of the variable delay field. Therefore, the number of bytes of the variable delay field is as many as the number of all frames representing the video. Then, each frame is displayed according to the delay time indicated in each byte, thereby representing a moving picture.

The number of layers field indicates the number of layers used to display an image constituting each frame and may be configured as 1 byte. Depending on the layer, each picture type can specify the arrangement order for composing the frame.

The Repeat Frag field is a field indicating whether the video is to be repeated and may be configured with 1 bit. That is, when the repeat flag field is set to 0, the corresponding video is repeatedly displayed on the user terminal.

The Palette Use field is divided into a Color Palette Use field and a Gray Palette Use field, which can be configured as 1 bit, respectively, and indicates whether the used palette uses 256 colors or 256 gray palettes.

The Better Compression field can be configured with 1 bit. If the Better Compression field is filled with 1, it indicates that the compression rate is important in compressing the video. If the Better Compression field is filled with 0, the compression speed is considered important. .

The Palette Compressed field can consist of 1 bit and indicates whether the palette is compressed.

The palette size field may not exist depending on the values of the color palette use field and the gray palette use field. That is, the palette size field exists as 2 bytes only when the color palette use field is 1 and the gray palette use field is 0, and indicates the size of the next palette data. If the color palette is not used and the gray palette is used, if the color palette use field is 0 and the gray palette use field is 1, the palette size field does not exist and the following palette data field does not exist.

The picture type level field is a field for the color of the picture type, which is a component of the video, and represents information on the image level such as black and white, 4-gray, 256 colors, and can be composed of 1 byte.

The Compression Method field indicates how the video data is compressed. The compression method uses various methods such as Hoffman Coding, W-Coding, Arithmetic Coding. It can be composed of 1 byte.

The number of picture types field is a field indicating the total number of picture types constituting a video and can be configured as 1 byte.

In addition, the video data includes headers of the frames constituting the video, moving data indicating how the picture types appearing in each frame are represented in each frame, and at which positions of the frames, and headers of the picture types constituting the frame And a picture type data section having picture type data.

 The frame header indicates a format in which each frame is expressed in the video, and FIG. 8 is a structural diagram showing the structure of each frame header constituting the video. Referring to FIG. 8, the inversion field indicating whether the frame is inverted, the whether frame is a simple frame indicating whether the frame belongs to the simple frame, the background color use field asking whether the background color is used, and the movement It consists of a moving data number field asking for the number of data.

The inversion field is a field indicating whether or not a frame is inverted and represented in a moving image.

The simple frame whether field indicates that the frame does not belong to the simple frame if the simple frame whether field is 0 in the frame, and if the simple frame whether field is 1, the frame is the simple frame.

The background color use field is a field indicating whether or not to express the background color in the frame when the frame is expressed.

The moving data number field is a field indicating how many picture types belonging to a frame are represented in the frame. When a picture type is expressed in a frame, the picture type can be expressed by zooming, rotating, or symmetry. The picture type represents the number of methods to be expressed when expressed in each method. If the picture type is enlarged, rotated, or mirrored and displayed in the frame, the number of moving data fields is three. The type of movement data displayed in the movement data number field is explained in the structural diagram of the movement data described below.

9 is a structural diagram showing a structure of moving data. The moving data is data indicating how the picture type expressed in each frame is expressed in each frame and in which position of the frame. The moving data indicates each ID which is a unique number of the picture type constituting each frame. Picture type ID field, layer field that specifies the order of composing each picture type, and when picture type is reversed, each picture type is inverted horizontally or vertically in each frame based on the screen of mobile communication terminal. A reversal field indicating whether the picture is reversed, a rotation field indicating whether or not the picture type is displayed while rotating counterclockwise on the screen of the mobile communication terminal, an enlarged field indicating whether each picture type is enlarged, Whether the picture type is enlarged by the magnification field When the name is changed, the expansion algorithm field indicating which algorithm is enlarged, the horizontal position shift field, the vertical position shift field, and the vertical position shift field, which indicate where the image is expressed from the upper left of the frame in the frame constituted by the picture type It is composed of a magnification field indicating the degree and how the picture type is represented in each frame.

In addition, the movement data and the frame header represent a form in which a picture type constitutes a frame, and thus may be defined as a frame header.

10 is a structural diagram of a picture type header of each picture type. The picture type header indicates whether the picture type is compressed or not, whether the picture type is compressed, the ID field of the picture type, the transition type field indicating whether it is a basic or transition picture type, and whether the picture type is a basic or transition picture type. Transition type status field, Transparency color type field that indicates how the picture type is displayed when the picture type is displayed in the frame, Image segmentation field that indicates whether the picture type is divided or not, and Transparency color field. It is composed.

In the Compression field, the picture type data is compressed according to various compression methods. However, even if the data is compressed according to the compression method, the amount of data does not decrease, but rather the amount of data increases. When the above example is described using Hoffman coding, Hoffman coding is compressed as shown in Table 2 according to the change of data values of 0 and 1. Referring to Table 2, if one value of 0 or 1 is repeatedly repeated, the compression rate is increased and the value of data is reduced. However, if 0 and 1 are repeated, the amount of data increases.

This field indicates whether or not data is compressed because the above problem may occur.

In order to express the picture type, the background color is defined as the transparency color, and the state of recognizing the internal shape of the circular picture type is defined as edge detection. Referring to FIG. 11 according to this definition, FIG. 11 (b) illustrates the use of edge detection without using the transparency color, and FIG. 11 (c) illustrates the transparency color and edge detection. Fig. 11 (d) is a diagram illustrating the use of the transparency color.

The segmentation field is a field indicating whether the data of the picture type is divided and received. If the amount of data of the picture type is large, it indicates that the data is divided into an arbitrary size and received.

In addition, the picture type data of FIG. 7 is data of picture types constituting a moving picture, and has information on actual picture types, for example, data such as color, size and shape of the picture type. And when a picture type is repeatedly displayed in a video, the picture type data is not transmitted repeatedly, but data of all picture types constituting the video is transmitted only once. After grasping picture type by using ID, display on frame.

If the transmitted video is black and white, it may be transmitted differently from the structure of FIG. 7. 12 is a data structure diagram of a black and white video. Referring to FIG. 12, an image header comprising an image identifier and a compression field, a frame number field indicating a total number of frames constituting a black and white video, and a figure showing the number of picture types used to construct a video A frame header composed of a type number field, a block number bit number field, and a compression method code indicating how the transmitted video is compressed using various compression methods, and each picture type constituting the video is represented in a frame. The black and white video data can be comprised by the moving data shown and the data field of each picture type which comprises a video.

Referring to Table 3, the image identifier and the compression field indicate the role that the data transmitted from the outside is a black and white video and whether or not the video data is compressed.

number field Explanation Image header One Image identifier Black and white video display 2 Compression Indication of compression Frame header 3 Number of frames Total number of frames in the video 4 Picture Type Total number of picture types in the video 5 Block number 6 Compression method Hoffman coding, Arismatic coding, W-coding, etc. Moving data 7 Include picture type 8 Picture type variation data 9 Transition Block 10 Transition Block 11 Transition block Picture type data 14 Horizontal block Number of horizontal blocks of picture type 15 Vertical blocks Number of vertical blocks of picture type 16 Block encoding status 17 Block data

The frame number field is a field indicating the number of total frames constituting the video.

The Number of Picture Types field indicates the number of picture types that make up a video. For example, if one picture type in a video appears five times in the video and another picture appears six times in the video, The type count field is filled with 10. The reason that 10 is filled instead of 11 is because it counts from 0 and fills it with 1 for 0 and 2 for 1.

The block number bit number field is a field indicating the number of blocks of the largest picture type among the picture types constituting the video.

The compression method field is a field indicating which of the various compression methods the transmitted video data is compressed.

The movement data is configured equal to the value of the total number of frames constituting the video, and represents the form in which the picture type data is represented in the frame. The movement data is composed of picture type inclusion field, picture type variation data field, transition block presence field, and transition block field.

The Include Picture Type field determines whether the picture or text type data is displayed in the frame. The number of bits of the field needs to be as many as the number indicated by the picture type number field of the header field. In the order of left to right bits, if the bit value is 1, the corresponding picture type data is displayed in the frame. If 0, the corresponding type data is not displayed in the frame. For example, if the number of types is 5 in the header field described later, the type inclusion keycode is composed of 5 bits. If the key code of type 1 of the first frame variation data is binary 10010, type 1 and 4 are included and type 2, 3, and 5 type data are not displayed in the first frame. Therefore, the following type mutation data code indicates how type data 1 is included in the first frame. In the picture type variation data, if five picture types are represented in the frame, the type variation data field is composed of five pieces. The horizontal position variation, the vertical position variation field and the picture type are displayed in the frame. It consists of a horizontal inversion field indicating whether it is inverted, a vertical inversion field, and an enlarged field having information on whether the picture type is enlarged or reduced. In addition, the transition block presence field is a 1-bit code indicating whether a transition block is included in a subsequent picture type variation field. If it is 1, it means that the transition block is inserted after. If it is 0, there is no transition block field, so this field is the end of the picture type variation field. The transition block field is a preliminary field to be used when the frame is formed of the above-described type data to complete a frame and then change some block values constituting the frame. The transition block field is a field selectively present according to the previous transition block presence field, and there may be a plurality of transition block fields.

The picture type data field is a field that contains information on the picture types composing the video. The basic structure is the number of horizontal blocks, the number of vertical blocks, the block encoding status field, and the data of each block. It consists of block data that is transmitted in one-dimensional bitstream.

The picture type is divided into basic picture type and transition picture type. If it is basic picture type, the random number of horizontal block and vertical block is encoded in the horizontal block and vertical block fields. In the block encoding status field, the total number of bits becomes the total number of blocks of the transition picture type data, i.e., the number of (horizontal blocks) x (vertical blocks), and each bit is compressed by various compression methods. Indicates whether this is done or not. For example, suppose n is any number between 1 and the total number of blocks. If the nth bit is 1, the nth block is compressed, and 0 is uncompressed. In addition, the block data are compared with the compressed data and the uncompressed data amount, and the ones having the smallest data amount are selected for one-dimensional bitstreaming for transmission.

If the picture type is a transition picture type, a block number field having data about the number of the identified transition block is identified by a block of any part of the picture type as a transition block different from the basic picture type, and a field indicating the end of the transition block. If both are 1, the length consists of the transition block end field as specified in the block number code bits. The transition block also transmits each block by one-dimensional bitstreaming.

FIG. 13 is a diagram illustrating a process of one-dimensional bitstreaming a block constituting a picture type constituting a black and white video in a video transmission method using wireless communication according to the present invention. Referring to FIG. 13, the picture type is arbitrarily divided into a plurality of blocks and transmitted in block units. FIG. 13 shows that one block of the plurality of blocks is configured with 64 bits. As shown in FIG. 13, the data value of the block can be one-dimensional bitstreamed by a zigzag method. In addition to the zigzag method, one-dimensional bitstreaming may be performed by any other method.

Step 3 (ST 130): If the determined picture type is the basic picture type, it is determined whether to divide the basic picture type into vertical blocks. The purpose of vertical block division is that when a picture type is transmitted from a video and displayed on the screen, the picture type may be so large that it may not detect a call signal to the mobile terminal while decoding the picture type. To display part of the type, check the call waiting state, and display the part again and check the call waiting state again, split the picture type vertically. However, in the encoding process, only the vertical block division is displayed, and in the decoding process, the vertical block division is used to display the picture type on the screen. In addition, if the picture type is a transition picture type, only the difference between the parent picture type and the transition picture type is transmitted. Therefore, there is no need to perform vertical block division.

Step 8 (ST 320): The picture type in which the vertical block division is designated determines the number and size of the designated vertical blocks. The total number of vertical blocks of the picture type is defined as M and the number of vertical blocks to be decoded is defined as m.

Step 9 (ST 330): The number m of vertical blocks is initialized to 1 and the first vertical block is decoded.

Step 10 (ST 340): Compare the total number of vertical blocks with the number of vertical blocks (Mm), if not zero, check call waiting, increase the value of m by 1, decode the mth vertical blocks, and decode the vertical blocks. Compare the total number of blocks with the number of vertical blocks and repeat until the compared value is zero.

Step 11 (ST 350): The portion of the picture types transmitted from the transition picture type determines the ID of the parent picture type of the transition picture type.

Step 12 (ST 360): The parent picture type ID is used to determine which of the base picture types is the picture type that has been transferred from the base picture type.

Step 13 (ST 370): After synthesizing the transmitted parts of the identified picture type and the transition picture type, the picture type is completed and the picture type is decoded. If the identified picture type is a picture type in which a vertical block is designated, the process of ST 320 to ST 340 is performed.

Step 7 (ST 460): The number m of vertical blocks is initialized to 1 and the first vertical block is decoded.

Step 8 (ST 470): Compare the total number of vertical blocks with the number of vertical blocks (Mm), if not zero, check for call waiting, increase the value of m by 1, decode the mth vertical blocks, and decode the vertical blocks. Compare the total number of blocks with the number of vertical blocks and repeat until the compared value is zero.

Step 9 (ST 480): The portion of the picture types transmitted from the transition picture type determines the ID of the parent picture type of the transition picture type.

Step 10 (ST 490): The parent picture type ID is used to determine which transition picture type is the picture type that has been transferred from the basic picture type.

Step 11 (ST 500): After synthesizing the transmitted parts of the identified picture type and the transition picture type, the picture type is completed and the picture type is decoded.

On the other hand, the video is completed by the wireless video transmission method of the present invention can be transmitted from the message center (MC) to each mobile communication terminal in a variety of ways, such as WAP, extended SMS, multimedia messaging system (MMS), the video is transmitted An embodiment of a method for sending video data by applying an extended SMS is described below.

According to TIA / EIA-637-A, a standard that defines SMS services in CDMA systems, the protocol for SMS transmission has the following three layer structures.

Relay Layer, Transport Layer, Teleservice Layer.

Among them, the relay layer is the lowest layer, and the teleservice layer is the highest layer.

SMS messages for video data services use these layer structures as they are, while the parameters of the relay layer follow the existing method of sending SMS messages, and the parameters of the transport layer and the teleservice layer are redefined or renewed. Use by definition.

First, there are three types of messages of the transport layer: a point-to-point message, a broadcast message, and an acknowledgment message. Use point-to-point messages because the purpose is to deliver data to specific users.

Table 3 shows the transport layer configuration defined in IS-637A.

SMS Point-to-Point Message Parameters Parameter Type Teleservice Identifier Mandatory Originating Address Mandatory Originating Subaddress Optional Destination Address Mandatory Destination Subaddress Optional Bearer Reply Option Optional Bearer data Optional

Among these, the Teleservice Identifier indicates the type of message transmitted by SMS. There are five types of teleservice identifiers supported by the TIA / EIA-637A as shown in Table 5.

Teleservice Identity TIA / EIA-637-A TELESERVICE TIA / EIA-41 Value IS-91 Extended Protocol Enhanced Services CMT-91 4096 Wireless Paging Teleservice CPT-95 4097 Wireless Messaging Teleservice CMT-95 4098 Voice Mail Notification VMN-95 4099 Wireless Application Protocol WAP

The specific values of this teleservice identifier are defined in another standard, TIA / EIA-41-D, which defines a value between 49152 and 65535 as a teleservice identity that the operator can arbitrarily select.

Therefore, if the teleservice identifier value is selected between 49152 and 65535, which is not currently used by the mobile communication service provider, video data may be transmitted using SMS.

The rest of the parameters of the transport layer are set in the same way as in the case of a normal SMS message. However, since the bearer data area contains information of a teleservice layer, which is a higher layer, this part is set as follows.

Once the bearer data area is configured, the subparameters of the SMS Deliver Message of the Teleservice layer and the new field of the last image information are added as shown in Table 5.

SMS Deliver Message Subparameter Subparameter Type Subparameter ID / Remark Message Identifier Mandatory 0 User Data Mandatory One Message Center Time Stamp Optional 3 Validity Period-Absolute Optional 4 Validity Period-Relative Optional 5 Reply Option Optional 10 Alert Message Delivery Optional 12 Image Information Mandatory Any number unused in 16 ~ 255

The Image Information subparameter uses one of the unused values between 16 and 255, which is set as reserved value in TIA / EIA-637-A. Among the subparameters of the SMS Deliver Message in Table 5, the remaining subparameters except for the user data and image information fields are used in the same way as the existing SMS messages. The subparameters of the User Data field and the Image Information field are defined in Tables 6 and 7, respectively.

User Data Subparameter Fields Length (Bits) Value / Remark SUBPARAMETER_ID 8 00000001 SUBPARAM_LEN 8 Variable MSE_ENCODING 5 Image encoding method NUM_FIELD 8 Length of CHARi CHARi 8 × NUM_FIELD Real image data Reserved 3 000

Image Information Subparameter Fields Length (Bits) Value / Remark SUBPARAMETER_ID 8 Any number unused in 16 ~ 255 SUBPARAM_LEN 8 00000010 IMAGE_ID 16 Identify each image sent MORE_DATA One 0 or 1 Reserved 7 0000000

Among the User Data subparameters of Table 6, MSG_ENCODING sets and uses a unique number (0 ~ 31) indicating the encoding method of the actual image data information contained in CHARi. The Image Information subparameter in Table 7 contains fields that contain information about the image data message currently being sent.

Among these, IMAGE_ID is the only field that distinguishes the video currently being sent, and MORE_DATA cannot be sent because one video is loaded in one SMS message. Indicates whether data to be present exists. If MORE_DATA is 1, it indicates that the data is continued in a later SMS message. If 0, it is the last message.

The operation of the terminal receiving the extended SMS message as described above is based on the operation of FIG. 21 presented in the previous operation description. Referring to Figure 21, after receiving the extended SMS message in the mobile terminal using the SIS image header of the extended SMS message is a video composed of the video configuration method available on the wireless communication of the present invention Make a grasp. In FIG. 21, the part of determining that the service identifier is the video data? Determines whether the Teleservice identifier is a value indicating a predefined video data message (from 49152 to 65535) in the SMS message structure. The part that turns out is determined by looking at the MORE_DATA field in the Image Information subparameter above, and the method of encoding video data is determined according to MSG_ENCODING of the User Data subparameter.

In this way, the terminal which has recovered the compressed / split transmitted image is used for displaying the idle screen.

On the other hand, an example of displaying a video on the standby screen is a terminal receiving a binary video via SMS (or any other method) may configure the entire screen with this video, or screen with other information (text, etc.) You can also mark For example, half of the standby screen is composed of the received image, and the other half is composed of system information such as current time and date.

In order to support these various modes, the terminal transmits information on the current screen mode to the HLR while the system proceeds with the registration procedure every time the screen mode is changed, and the content server CS displays the standby screen display mode of the terminal. The information about is obtained from the HLR, and the video is configured and transmitted according to the idle screen mode specification of the terminal.

According to the present invention, a method for providing a video screen of a mobile communication terminal according to the present invention configures and compresses video data using a predetermined algorithm and transmits the video data to a terminal, thereby displaying a video on a standby screen of the mobile communication terminal. The screen of the terminal can be configured in various ways, and the video can be easily transmitted and received. Therefore, there is an effect that can transmit the video data to the terminal in the current mobile communication system and display the video as a mobile communication terminal screen.

In addition, since the video data corresponding to the display device of the terminal having a different standard can be configured in the network server and transmitted to the terminal, the video can be represented on various terminals.
