The present invention relates to an apparatus and method for providing a real-time chat service having a function of transmitting and receiving voice emoticons, and more particularly, to transmit and receive a voice emoticon in the form of a low volume voice file for expressing emotions of a conversation participant in a real-time chat service such as a messenger. The present invention relates to a chat service providing apparatus and method.

Recently, as high-speed communication services including the Internet are available at a low cost, a large number of computer users use services such as mail, web surfing, and chatting using wired and wireless communication networks. Among them, a chat service or a messenger service is widely used because it can communicate with a plurality of users connected to a communication network in real time.

The chat service is a service in which a large number of users connected to the chat server exchange texts with other users using a chat program implemented with the server and the Common Gateway Interface (CGI). To execute a chat service, a user selects a party to chat with by opening a chat room or designating a specific user. Next, when the user inputs a desired text message in the text input window, the text is transmitted to the selected computer counterpart's computer system and the message is displayed.

On the other hand, the messenger service is a service that transmits digital data such as text and images determined by the caller to the counterpart's computer system via the messenger server. The messenger service is a chat service performed by using a messenger program. The messenger program refers to software that is always connected to the messenger server to receive limited services such as sending and receiving messages with others. The messenger screen is composed of small windows so as not to disturb the desktop or the currently working screen. Occupies a part. Messenger is software that allows two users to send a small amount of text data in real time, between an e-mail system where recipients need to check their mailboxes from time to time, and chats where people need to connect to a specific server at the same time at a given time. It can be seen as intermediate.

Since the above-described chat service or messenger service is provided based on the transmission of a message in a text form prepared by the conversation participants, it is difficult to express the emotions of the conversation participants more easily. In order to overcome the shortcomings of chat service or messenger service, "emoticon", which is a special character combination for expressing emotions, was mainly used. These text emoticons have evolved due to text-oriented communication, but the text emoticons have a limited state of emotion that can be expressed, and when the other person is not familiar with the emoticons, the emoticons cannot exhibit the function of emoticons.

Recently, image emoticons have been used in accordance with the user's point that it is difficult to express one's emotion only with text emoticons. That is, by adding an appropriate image emoticon in addition to image data such as a text-based message or a card delivered to the other party, the conversation participant can appropriately express their feelings. The sun in which these image emoticons are used is largely divided into two. First, the user selects one of various emoticon images possessed by a chat server, a mail server, a messenger, a card transmission server, or a program and transmits the text message and the emoticon image to the counterpart's computer screen by sending the text along with the text to the counterpart or the service providing server. The first way is to display together. In the second method, a message inputted as text is analyzed to analyze the emotions of the corresponding chat subject, and then automatically extracts an image emoticon corresponding to the chat subject and transmits it to the counterpart. According to this second form, it simply finds a pictogram representing an emotion in the input text and converts the pictogram into an image corresponding to it, or uses a punctuation mark such as an onomatopoeia, a prototype, or a question mark. It may be implemented in a manner of recognizing and controlling the facial expression, motion, and the like of the character.

However, although the participants can convey their feelings visually to each other by the text or emoji, the emotions expressed by the characters or emoji are merely visual, so they can convey the emotions of the participants more realistically. There is no problem.

The technical problem to be achieved by the present invention is to provide a real-time chat service providing apparatus and method having a function of transmitting and receiving voice emoticons that can be coupled to the existing chat service or a messenger service to transmit the emotion of the conversation participants to the other conversation participants by sound. There is.

The technical problem to be achieved by the present invention is to implement a real-time chat service providing method having a function of transmitting and receiving voice emoticons that can be coupled to the existing chat service or a messenger service to transmit the emotions of the conversation participants to the other conversation participants by sound.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the apparatus and method for providing a real-time chat service having a function of transmitting and receiving voice emoticon according to the present invention. A chat server or a messenger server for providing a real-time chat service may be interposed between the apparatuses for providing a real-time chat service having a function of transmitting and receiving voice emoticons according to the present invention. In this case, the configuration and function of each server is well known to those skilled in the art, and the present invention is a change to the user terminal only without a change to the server for providing a conventional chat service Since it is intended to implement the function of transmitting and receiving voice emoticons, a detailed description thereof will be omitted.

1 is a block diagram showing a detailed configuration of an embodiment of a real-time chat service providing apparatus having a function of transmitting and receiving voice emoticons according to the present invention.

1, the real-time chat service providing apparatus 100 having a voice emoticon transmission and reception function according to the present invention includes a communication unit 110, a chat performing unit 120, a packet inspection unit 130, an image decoder 140, The voice decoder 150, the emoticon generator 160, the storage unit 170, and the output unit 180 are provided.

The communication unit 110 is connected to a wired / wireless communication network such as wired / wireless internet, wired / wireless LAN, wired / wireless telephone network, and the like, and a real-time chat service providing apparatus 100 having a transmission / reception function of a voice emoticon according to the present invention is a server such as a chat server or a messenger server. Allows the device to send and receive data to and from other wired and wireless terminals, such as personal computers, personal digital assistants (PDAs), mobile phones, and so on. The real-time chat service providing apparatus 100 having a transmission / reception function of a voice emoticon according to the present invention may be a dedicated terminal having a chat function or a terminal having a communication function such as a personal computer, a PDA, a mobile phone, and the like.

The chat performing unit 120 provides a user with a real-time chat service with another user connected through a communication network. When the user executes the chat application, the chat performing unit 120 connects to the chat server and transmits the chat counterpart information selected by the user to the chat server. Next, the chat performing unit 120 transmits the text message input by the user to the chat server, requests a delivery to the counterpart terminal, and performs a general chat process of displaying the text message transmitted from the chat server. At this time, the chat performing unit 120 may transmit a picture file corresponding to the image emoticon selected by the user to the chat server together with the text message, or display the image emoticon received from the chat server together with the text message.

In connection with the display of the image emoticon inserted into the message, the chat performing unit 120 checks whether the image file is included in the received message packet. If an image file is included in the message packet, the chat execution unit 120 outputs the image file at a designated point in the text message. The format of the image file may be BMP, PNG, or the like. BMP files consist of file headers, bitmap headers, and colormaps and actual image data. Among the elements constituting the BMP file, relevant to the present invention are the size fields (bfSize), the plurality of reserved fields (bfReserved1 and bfReserved2), and the image data offset field (bfOffBits) of the BMP file constituting the BMP file header. Since the structure of the BMP file is well known, its detailed description is omitted. PNG files, on the other hand, are made up of units called chunks. PNG files must have IHDR chunks, PLTE chunks, IDAT chunks, and IEND chunks, and additional additional chunks may be added. Each chunk consists of a length field (Length), a type field (Chunk Type), a data field (Chunk Data), and a CRC field (CRC), and actual data is recorded in the data field.

The packet inspecting unit 130 examines a packet input through the communication unit 110 when the chat program is executed. 2 is a data structure of an emoticon transmitted and received by a real-time chat service providing apparatus having a transmission / reception function of a voice emoticon according to the present invention written in a BMP file. Referring to FIG. 2, the voice emoticon 200 includes a file header 210, a file information header 220, a color map 230, voice data 240, and image data 250, similar to a typical BMP file. It is composed. These voice emoticons differ from general BMP files in that voice data exists between the color map and the actual image data. Therefore, the address value of the start point of the image data is recorded in the actual image data offset (bfOffBits) of a typical BMP file, but the address value of the next bit of the color map is recorded, but the voice data is recorded in the actual image data offset (bfOffBits) of the voice emoticon. The address value of the next bit of is recorded.

The packet inspecting unit 130 is recorded at the start position of the image data calculated based on the file size recorded in the BMP file header and the image size recorded in the BMP information header and the actual image data offset (bfOffBits) of the BMP file header. If the start position of the existing image data does not match, it is determined as a voice emoticon. In this case, the packet inspecting unit 130 provides the BMP file determined as the voice emoticon to the image decoder 140 and the voice decoder 150. In contrast, the packet inspecting unit 130 calculates the starting position of the image data calculated based on the file size recorded in the BMP file header and the image size recorded in the BMP information header, and the actual image data offset of the BMP file header (bfOffBits). If the starting position of the image data recorded in the same, the BMP file is provided only to the image decoder 140. As described above, the packet inspecting unit 130 is installed at the rear end of the communication unit 110 and configured to selectively provide the packet introduced through the communication unit 110 to the image decoder 140 and the voice decoder 150. Alternatively, the packet inspection unit 130 may be configured to chain the data transmitted from the communication unit 110 to the image decoder 140 to provide the voice decoder 150 when it is confirmed as a voice emoticon.

On the other hand, the real-time chat service providing apparatus 100 having a transmission and reception function of the voice emoticon according to the present invention can accommodate an image emoticon or voice emoticon created in various image formats (BMP, GIF, JPG, TIF, PNG, etc.) have. In this case, the packet inspecting unit 130 determines the format of the image emoticon by the extension of the emoticon file included in the received message. That is, the packet inspecting unit 130 retrieves the packet introduced through the communication unit 110, and if an acceptable file extension is found, separates the corresponding part from the packet to obtain the file name of the complete image emoticon. Check whether a voice emoticon is found from the corresponding image file.

If the image emoticon or voice emoticon is written in PNG format, the packet inspecting unit 130 checks whether an image file exists in the received packet, and if the image file exists, checks the type of chunk constituting the image file. do. At this time, a string (eg, voice emoticon or voice emoticon, etc.) promised in advance is recorded in the type field of the chunk including the voice emoticon. The packet inspecting unit 130 provides the voice decoder 150 with the chunk identified as the voice emoticon through the inspection of the type field.

The image decoder 140 decodes the image file flowing from the communication unit 110 or the packet inspecting unit 130 and outputs an image. The real-time chat service providing apparatus 100 having a function of transmitting and receiving voice emoticons according to the present invention includes a number of image decoders 140 corresponding to an acceptable image format, and the configuration and function of the image decoder according to each image format. Since it is well known to those skilled in the art to which the present invention belongs, only the BMP decoder will be described in detail. The BMP decoder determines the BMP by whether the first 2 bytes of the BMP file start with BM, whether the exact file size in bytes and the value recorded in the file size field in the header match, and whether 0 is recorded in the reserved field. If the file is checked, and if it is confirmed as a BMP file, the data from the bit recorded in the actual image data offset to the last bit of the BMP file is restored using the BMP information header and the color map.

The voice decoder 150 extracts voice data from the image file flowing from the packet inspecting unit 130 and then decodes the audio data to output sound. When the image file is a BMP file, the voice decoder 150 extracts the voice data recorded from the next bit of the color map of the BMP file to the previous bit of the start position of the image data grasped from the BMP file header. Next, the voice decoder 150 decodes and outputs the extracted voice data. Meanwhile, when the image file is a PNG file, the voice decoder 150 extracts voice data from chunk data, which is a component of a private chunk, which is a chunk that a user can directly generate, and decodes the audio data to output sound. At this time, data existing from the start position of chunk data to the end position of chunk data from the next byte 8 bytes is voice data. The voice decoder 150 may include a data extractor 150-1 and an audio output unit 150-2 for the above operation.

On the other hand, the voice data carried in the image file may be composed of file identification information and sound information. At this time, the file identification information is located in front of the voice data as a unique identifier assigned to each sound information. In this case, the voice decoder 150 stores the voice data extracted from the image file in the storage unit 170 by separating the file identification information and the sound information, and when the image file including the voice data is received later, the file obtained from the voice data. The storage unit 170 is searched based on the identification information to determine whether the same file identification information exists. If the same file identification information exists in the storage unit 170, the voice decoder 150 reproduces the sound information stored in the storage unit 170. By adopting such a method, it is possible to prevent the delay between the text output time and the sound output time. The voice data (when the voice data includes file identification information) can be created in various formats such as wma, mp3, midi, and the like. The voice data (if the voice data includes file identification information) is preferably a short onset of words such as "black and white", "ah", "hahaha", and may be simple words such as "I love you" and "I'm sorry". have.

The emoticon generator 160 inserts sound data selected by the user in the form of a BMP file to generate a voice emoticon. The configuration and function of the emoticon generator 160 is almost the same as the BMP encoder except for the part related to the insertion of voice data. The emoticon generating unit 160 records the voice data selected by the user from the next bit of the color map of the BMP file. In addition, the emoticon generator 160 creates a BMP file header and a BMP information header, and records the address of the next bit after the last bit in which the voice data is recorded in the image data start position field of the BMP file header. Meanwhile, if the user selects both the image emoticon and the voice emoticon to output the sound together with the output of the image, the emoticon generator 160 loads the voice data in the image file corresponding to the image emoticon selected by the user. When the image file is in the BMP format, the emoticon generating unit 160 inserts voice data between the color map and the image data and changes the file size of the BMP file header and the start position of the image data. In contrast, when the image file is a PNG format, the emoticon generator 160 generates a single PNG file by containing voice data in a private chunk, which is an additional chunk.

Meanwhile, the voice emoticon may be generated during a chat, but may be created in advance and stored in the storage unit 170. In this case, the voice emoticon may have a file name such as "voice_love.bmp". The voice emoticon may be linked to a separate voice emoticon list as "I love you"-"voice_love.bmp", and the user may enter the text "I love you" in the chat window. When input, the chat performing unit 120 transmits the voice emoticon "voice_love.bmp" corresponding to "I love you" from the voice emoticon list to the terminal of the chat counterpart.

The storage unit 170 stores image emoticons, voice data (which may take the form of sound information corresponding to file identification information), and the like. In addition, the storage unit 170 may temporarily store the image file received through the communication unit 110. The output unit 180 outputs a message received from the chat execution unit 120, an image received from the image decoder 140, and a sound received from the voice decoder 150.

3 is a flowchart illustrating a process of inserting a voice emoticon into a message in a method for providing a real-time chat service having a function of transmitting and receiving voice emoticons according to the present invention.

Referring to FIG. 3, when a user executes a chat application, the chat execution unit 120 connects to a chat server or a messenger server, and then transmits the chat counterpart information selected by the user to the chat server or a messenger server. A communication path is set between terminals of the chat counterpart (S300). If the user selects to insert the voice emoticon during the chat, the emoticon generator 160 checks whether the image emoticon is selected (S310). If the user selects an image emoticon (S320), the emoticon generator 160 generates voice emoticons by loading voice data into an image file corresponding to the image emoticon selected by the user (S330). In contrast, if the user selects only the voice emoticon (S320), the emoticon generator 160 generates a voice emoticon of a file type used based on the voice data selected by the user (S340).

On the other hand, when the image file used is a BMP format, the emoticon generating unit 160 records voice data selected by the user from the next bit of the color map of the BMP file, and creates a BMP file header and a BMP information header. In contrast, when the image file is a PNG format, the emoticon generator 160 generates a single PNG file by containing voice data in a private chunk, which is an additional chunk.

4 is a flowchart illustrating a process of playing a voice emoticon carried in a message in a method of providing a real-time chat service having a function of transmitting and receiving voice emoticons according to the present invention.

Referring to FIG. 4, when the chat program is executed, the packet inspecting unit 130 inspects a packet input through the communication unit 110 (S400). First, the packet inspecting unit 130 determines the file format of the image emoticon by the extension of the emoticon file included in the received message (S410). If the file format of the image emoticon is determined as BMP (S420), the packet inspecting unit 130 may determine the starting position of the image data calculated based on the file size recorded in the BMP file header and the image size recorded in the BMP information header. If the starting position of the image data recorded in the actual image data offset bfOffBits of the BMP file header does not match, it is determined as a voice emoticon and the voice decoder 150 is provided to the voice decoder 150 (S430). When the image file flowing from the packet inspection unit 130 is a BMP file, the voice decoder 150 records the voice recorded from the next bit of the color map of the BMP file to the previous bit of the start position of the image data grasped from the BMP file header. The data is extracted and the extracted voice data is decoded and output (S440).

On the contrary, if the file format of the image emoticon is detected as a PNG (S420), the packet inspecting unit 130 provides a private chunk to the voice decoder 150 (S450). When the image file flowing from the packet inspecting unit 130 is a PNG file, the voice decoder 150 extracts voice data from chunk data, which is a component of a private chunk, which is a chunk that can be generated by the user, and then decodes the audio data to output sound. (S460).

The invention can also be embodied as computer readable code on a computer readable recording medium. The computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and may also be implemented in the form of a carrier wave (for example, transmission over the Internet). Include. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion.
