Abstract

When an image recording start instruction or an image recording end instruction is transmitted from a terminal, a DTMF detecting section (106) detects a DTMF signal and outputs the result of the detection to a control unit (107). The control unit (107) outputs the received image recording start instruction or the received image recording end instruction to an image data conversion section (105) and a switching section (108). When the image recording start instruction is inputted, the image data conversion section (105) converts received image data (103) into image data coded in an intra mode to output it to the switching section (108). The switching section (108) outputs the image data outputted from the image data conversion section (105) to a storage device (110) at the time when the image recording start instruction is inputted and after the image recording start time, continuously outputs the received image data (103) to the storage device (110) until the image recording end instruction is inputted.

Description

MOBILE IMAGE STORAGE SYSTEM, MOBILE IMAGE STORAGE METHOD, AND MOBILE IMAGE STORAGE PROGRAM Technical Field The present invention relates to a mobile image storage system, a mobile image storage method, and a program Mobile image storage to convert and store mobile images that have been received as input. Previous Branch Videophone services and mobile image distribution services using portable terminal devices in an online switching network are being put to wide use. The services in which the mobile image data received from portable terminal devices in an online switching network or IMS (Multimedia Subsystem I) / NGN (Next Generation Network) are stored in a server and then distributed by the served and expected to become widely popular. MPEG-4 (ISO / IEC 14496-2: 2003"Coding of Audio Information Technology and Visual Video Objects - Part 2: Visual ") is widely used as a mobile image coding method in the portable terminal devices of the Third Generation Partnership Project (3GPP) MPEG-4 incl * uye intramode, in which the coding uses only the image of an acting, and intermode, camera in which the coding is carried out by reference to the images of past frames In the intramode, the input pixels are subjected to a DCT (Discrete Cosine Transformation) which is carried out in units referred to as "macroblocks", after which the DCT coefficients are subjected to variable length coding.In the intermode, the motion compensation diffusion is carried out between input pixels and decoded pixels from past frames to find differential pixels, then the differential pixels are subjected to DCT, the motion and coefficient vectors DCT entities undergo variable length coding. When mobile image data that has been transmitted from a terminal device is stored, the designated interval data in the mobile image data transmitted in real time from the terminal device is stored in a mobile image storage device (e.g. reference to Patent Document 1). Because the images of previous frames can not be referenced for the front frame of the image stored at the time of playback, the front frame must be converted into data that has been subjected to intramode coding. Figure 1 is a block diagram showing an example of the typical configuration of a mobile image storage system. In the mobile image storage system shown in Figure 1, the data receiver 901 receives data 900 for receiving a terminal device (not shown). The reception data 900 includes control data 902, which is information related to image coding, image data 903, and audio data 904. The control data 902 and the image data 903 are applied as input to the image data converter 905. The image data converter 905 converts the forward frame of the image data 903 that has been received in an intramode frame based on the information obtained from the control data 902. The image data after the conversion is then "supplied to the switch 906. The audio data 904 is applied as input to the switch 906. When the conversion principle is notified by the conversion instruction signal 909, the switch 906 applies data 904 of audio and image data that have been converted as input to the data storage unit 908 until the end of conversion is signaled by the conversion instruction signal 909. However, when the image storage system While mobile phone stores mobile images that are transmitted from terminal devices in real time, instructions at the beginning and end of storage should be sent from the terminal devices to the mobile image storage system. Terminal device does not recognize the method of instructing the beginning and end of storage. Patent Document 1: JP-A-2002-232847 (paragraphs 0002-0005, Figure 2).

The mobile image storage system may be provided with a control module for implementing the control so that the amount of code in intramode image data is a predetermined value. The mobile image storage system can be provided with a control module to control the amount of intramode coding so that the amount of code after conversion by the converter is equal to the amount of code before the conversion. In accordance with the present invention, a method is provided for instructing the start and end of storage of a mobile image storage system to terminal devices for transmitting instructions for the start and end of storage in a mobile image storage system from devices terminals, and based on the instruction signals of the terminal devices, the mobile images transmitted from the terminal devices in real time can be stored.

WORKING EXAMPLES First Working Example The following explanation with respect to the first working example of the mobile image storage system (mobile image storage device) in accordance with the present invention with reference to Figure 4. The present example of work corresponds to the first mode (see Figure 2) that is used in a packet switching network. The present working example and each of the second to fifth working examples are examples that use DTMF signals based on RFC3833 as the instruction signals from the terminal device. The data receiver 101 which is equivalent to the receiver 11 shown in Figure 2 analyzes the received packets 100 that were received from a terminal device (not shown) and outputs as at least one between reception control data 102, data 103 of reception image, reception audio data 104, and DT data 116. The reception control data 102 is supplied to control the module 107. The reception image data 103 is supplied to the image data converter 105, which is equivalent to the converter 15 shown in Figure 2, and to the switch 108. The reception audio data 104 is supplied to the switch 108. The DTMF data 116 is supplied to the DTMF detector 106, which is equivalent to the detector 16 shown in Figure 2. At the beginning of the communication, the control module 107 supplies the data transmitter 114, which is equivalent to the transmitter 14 shown in Figure 2, with the control data 111 SIP / SDP based broadcasting to perform call connection and capacity exchange between the terminal device and the mobile image storage device. After the termination of the capacity exchange, the control module 107 supplies the data receiver 101 with the port number for the reception of data 103 of reception and reception of audio data 104 and supplies the data transmitter 114 with the number port for data transmission 112 of audio data transmission 113. In addition, the control module 107 supplies the storage device 110, which is equivalent to the storage unit 10 shown in Figure 2, with a guidance mobile image transmission instruction signal showing the method of operation in the terminal device. . Upon receiving as input the guide mobile image transmission instruction signal, the storage device 110 supplies transmission image data 112 and transmission audio data 113 corresponding to the moving guide image to the data transmitter 114. The mobile guide image contains at least one between speech and an image that has the content "Please press the number 0 'when the registration starts and the number l' when the registration is finished". The data transmitter 114 converts the packets at least one between transmission control data 111, transmission image data 112, and transmission audio data 113 and supplies transmission packets 115. When the mobile image storage device is realized by a device such as a server device that includes a computer, the ability to analyze the packets 100 received in the data receiver 101, the ability to convert data into packets in the transmitter 114 of data, and the image data converter 105, the DTMF detector 106, and the control module 107 are made by a program and a CPU / running processes in accordance with the program. The terminal device transmits a register start instruction or an end of register instruction by DTMF signals based on IETF RFC2833. When receiving from a terminal device a DTMF signal based on IETF RFC2833 as a registration start instruction or an end of registration instruction, the data receiver 101 supplies DTMF data 116 to the DTMF detector 106. The DTMF detector 106 analyzes the DTMF data 116 that has been received as input and supplies the results of the analysis as DTMF signal detection results to the control module 107. When the DTMF signal detection results to indicate a registration start instruction, the control module 107 supplies the registration start instruction to the image data converter and switch 108. When the DTMF signal detection results to indicate an end instruction of registration, the control module 107 supplies an end-of-registration instruction to the image data converter 105 and switch 108. During the input of a registration start instruction, the image data converter 105 converts the data reception 103 of image at the time of input into image data that has been subjected to intramode coding and supplies the result to switch 108. In order to carry out this process, image data converter 105 constantly decodes image 103 of image reception that has been received as input, and upon receiving a registration start instruction as input, submits the decoded image to encoding n intramodo. At the time of entry of a registration start instruction, the switch 108 supplies the storage device 110 with image data that has been subjected to intramode coding and supplied with the image data converter 105. From the time the registration was started until the entry of an end of registration instruction, the switch 108 continues to supply reception image data 103 to the storage device 110. The switch 108 further supplies data 104 for receiving audio to the storage device 110 from the input of a registration start instruction to the entry of an end of registration instruction. Second Work Example. The following explanation relates to the second working example of the present invention with reference to Figure 5. The present working example corresponds to the first embodiment that is used in a packet switching network (see Figure 2). The data receiver 101 analyzes the received packets 100 that have been received from a terminal device and supplies as an output less between the control reception data 102, image reception data 103, audio reception data 104, and data 116. of DTMF. The control reception data 102 is supplied to the control module 107. The image reception data 103 is supplied to the image data converter 105 and to the switch 108. The audio reception data 104 is supplied to the switch 108. The DTMF data 116 is supplied to the DTMF detector 106 in order to carry out the connection and exchange of capacity between a terminal device and the mobile image storage device at the beginning of communication, the control module 107 supplies data to the transmitter 114 with the data transmission data 111 based on SIP / SDP as prescribed by IETF RFC3261 / RFC2327. At the end of the capacity exchange, the control module 107 supplies the data receiver 101 with the port number to receive image 103 data and audio reception data 104, and transmits the port number to transmit data 112 of transmitting image and data 113 of audio transmission to the data transmitter 114. The control module 107 further supplies the storage device 110 with a guide mobile image transmission instruction signal indicating the method of operation in the terminal device. Upon receipt of the guidance mobile image transmission instruction signal as input, the storage device 110 supplies image transmission data 112 and audio transmission data 113 corresponding to the moving guide image to the data transmitter 114. The mobile guide image contains at least one between speech and images that have the content, for example, "Please press the number '0' when the registration starts and the number * 1 'when the registration ends". The data transmitter 114 converts at least one packet between transmission control data 111, image transmission data 112, and audio transmission data 113, and supplies the resulting transmission packets 1154. Upon receiving the IET-based DTMF signal RFC2833 as a registration start instruction or an end-of-register instruction of a terminal device, the data receiver 101 supplies DTMF data 116 to the DTMF detector 106. The DTMF detector 106 analyzes the DTMF data 116 that has been received as input and supplies the DTMF signal detection results to the control module 107. When the DTMF signal detection result indicates a registration start instruction, the control module 107 supplies the registration start instruction to the image data converter 105 and switch 108. When? Resultados signal detection results of DTMF indicate an end-of-registration instruction, the control module 107 supplies the end-of-registration instruction to the image data converter 105 and switch 108. During the input of a registration start instruction, the image data converter 105 converts the reception of the image data 103 at that time into image data which have been subjected to intramode coding and supplies the result to the switch 108. In order to carry out this process, the image data converter 105 constantly decodes the receiving image data 103 that are received as input, and upon receipt of a registration start instruction, subject the decoded image to coding n intramodo. At the time of entry of a registration start instruction, the switch 108 supplies the media synchronization module 109 with image data which has been subjected to intramode coding and which has been supplied from the image data converter 105. From the time the registration was initiated until the entry of an end of registration instruction, the switch 108 continues to supply image reception data 103 to the media synchronization module 109. The switch 108 supplies audio reception data 104 to the media synchronization module 109 from the entry of a registration start instruction to the entry of an end of registration instruction. The media synchronization module 109 confers time information to the audio data and image data that has been converted and supplies this data to the storage device 110. At this time, as a result of intramode encoding, the amount of code in the image data of the time the recording is started is usually greater than the amount of coding before the conversion. In this way, when image and speech are synchronized at the moment when the conversion starts, the presentation of the image is delayed. The media synchronization module 109, therefore, adjusts by shifting the audio data again as shown in frame N in Figure 6A to obtain picture and speech synchronization. In other words, when the amount of coding in the image data has been converted by the image data converter 105 changes with respect to the amount of coding before conversion, the media synchronization module 109 adjusts the information related to the timing of playback of audio data. At this time, when the lack of audio data corresponding to the front image causes a problem at the time of playback, the media synchronization module 109 inserts, for example, silence data corresponding to the front image data which have undergone conversion, as shown in Figure 6B. Third Working Example The explanation below refers to the third working example of the present invention with reference to Figure 7. The present working example corresponds to the first mode that is used in a packet switching network (see Figure 2) . The data receiver 101 analyzes packets 100 received from a terminal device and outputs at least one among the reception control data 102, data 103 of image reception, data 104 of audio and data reception 116 dew DTMF. The control reception data 102 is supplied to the control module 107. The image reception data 103 is supplied to the image data converter and switch 108. The audio reception data 104 is supplied to the switch 108. The DTMF data 116 is supplied to the DTMF detector 106. The control module 107 supplies the data transmitter 114 with transmission control data 111 based on SIP / SDP as prescribed by IETF RFC3261 / RFC2327 to carry out call connection and capacity exchange between a terminal device and the device. mobile image storage at the beginning of a communication. After the termination of the capacity exchange, the control module 107 supplies the port number for receiving data 103 of image reception and data 104 of audio reception to the data receiver 101, and supplies the data transmitter 114 with the number of port for transmitting data 112 of image transmission and data 113 of audio transmission. The control module 107 further supplies the storage device 110 with a guidance mobile image transmission instruction signal showing the method of operation in the terminal device. Upon receiving the guide mobile image transmission instruction signal as input, the storage device 110 supplies the data transmitter 114 with image transmission data 112 and audio transmission data 113 corresponding to the moving guidance image. The mobile guide image contains, for example, at least one between speech and an image that has the content "Please press the number 090 when the registration starts and the number 010 when the registration is finished". The data transmitter 114 converts at least one of the control transmission data 111, image transmission data 112, and audio transmission data to packets 113 and supplies the transmission packets 115. Upon receiving the DTMF signals based on IETF RFC2833 as a registration initiation instruction or an end registration instruction of a terminal device, the data receiver 101 supplies DTMF data 116 to the DTMF detector 106. The DTMF detector 106 analyzes DTMF data 116 that has been received as input and supplies detection results of the DTMF signal to the control module 107. When the DTMF signal detection results indicate a registration start instruction, the control module 107 supplies a start registration instruction to the image data converter and switch 108. When the DTMF signal detection results indicate an instruction at the end of registration, the control module 107 supplies an end-of-registration instruction to the image data converter and switch 108. Upon receipt of a registration start registration instruction as input, the image data converter 125 converts the image acquisition data 103 at that time in image data that has been subjected to intramode coding and supplies the result to the switch 108. In order to carry out this process, the image data converter 125 constantly decodes the reception data 103 that are received as input, and after inputting a start registration instruction, submit the images decoded in intramode coding. The image data converter 125 here complements the control so that the image data size after conversion is made from a predetermined target value. Figure 8 is a block diagram showing the configuration of the image data converter 125. As shown in Fig. 8, the image data converter 125 is provided with an image decoder 701, code quantity control module 705, and image encoder 707. The image decoder 701 supplies the code quantity control module 705 with: decoding time quantization precision 702, which is the precision of quantification 'at the time of decoding that is obtained when it is decoded; and amount 703 of receive code in frame units, macroblock units, or video packet units, which are macroblock groups, in image receiving data 103 that has been subjected to MPEG-4 encoding. The code quantity control module 705 uses at least one between decoding time quantization precision 702, reception coding quantity 703, and target code quantity 704 to determine the quantization precision 706 at the time of coding, and supplies the result to the image encoder 707. The image encoder 707 performs sanctification in accordance with the quantization precision 706 to execute image coding. The decoding time quantization precision 702 is a parameter obtained when the image decoder 701 performs the decoding and is effective information when the coding is controlled so that the amount of coding after the coding approaches the amount 704 of meta code. For example, when the reception code quantity 703 is greater than the target code quantity 704, the code quantity control module 705 implements control so that the coding time quantization precision 706 is stronger than the precision 702 decoding time quantization. When the amount of target code 704 is exceeded even when the quantization precision 706 during coding is set to the strongest level, the amount of code supplied can be reproduced by setting to "0" several of the higher order values of the coefficient of DCT during coding. Adjusting the target code quantity 704 prevents large variations in the amount of code in the image data that has been encoded by the image encoder 707. The switch 108 shown in Figure 7 supplies the storage device 110 with image data which has been subjected to intramode coding and which has been supplied from the image data converter 125 at the time of entry of a start instruction of registry. The switch 108 continues to supply image receiving data 103 to the storage device 110 from the time the registration was initiated until the entry of an end of registration instruction. The switch 108 further provides reception of audio data 104 to the storage device 110 from the entry of a registration start instruction to the entry of an end of registration instruction. Fourth Working Example The explanation below refers to the fourth working example of the present invention with reference to Figure 9. The present working example corresponds to the first embodiment that is used in the packet switching network (see Figure 2) . The data receiver 101 analyzes the received packets 100 that have been received from a terminal device, and outputs as at least one between reception control data 102, image reception data 103, audio reception data 104, and data 116 of DTMF. The reception control data 102 is supplied to the control module 107. The image reception data 103 is supplied to the image data converter and switch 108. The audio reception data 104 is supplied to the switch 108. The DTMF data 116 is supplied to the detector 106 of DT F. The module 107 The control device supplies the data transmitter 114 with transmission control data 111 based on SIP / SDP as prescribed by IETF RFC3261 / RFC2327 to carry out call connection and capacity exchange between a terminal device and the storage device. mobile image at the beginning of communication. At the capacity exchange termination, the control module 107 supplies the data receiver 101 with the port number to receive data 103 of image reception and data 104 of audio reception, and supplies the data transmitter 114 with the port number to transmit image transmission data 112 and audio transmission data 113. The control module 107 further supplies the storage device 10 with a guidance mobile image transmission instruction signal indicating the method of operation in the terminal device. Upon receiving as input the guide mobile image transmission instruction signal, the storage device 110 supplies the data transmitter 114 with image transmission data 112 and audio transmission data 113 corresponding to the moving guide image. The mobile guide image contains, for example, at least one between speech and images that have the content "Please press the number? 0 'when the registration starts and the number * 1' when the registration is finished.2 The transmitter 114 The data stream converts at least one packet between transmission control data 111, image transmission data 112, and audio transmission data 113, and provides transmission packets 115. Upon receipt of a DTMF signal based on IETF RFC2833 as a registration start instruction or an end of registration instruction from a terminal device, the data receiver 101 supplies DTMF 116 to the DTMF detector 106. The DTMF detector 106 analyzes the DTMF data 116 that has been received and supplies the results DTMF signal detection to the control module 107. When the DTMF signal detection results indicate a registration start instruction, the control module 107 supplies the Startup recording to the image data converter and switch 108. When the DTMF signal detection results indicate an end registration instruction, the control module 107 supplies an end instruction to the converter. 125 image data and switch 108. During the input of a registration start instruction, the image data converter 125 converts the reception image data 103 at this time into image data that has been subjected to intramode coding , and supplies the result to the switch 108. In order to carry out this process, the image data converter 105 constantly decodes the image reception data 103 that is received as input, and when a registration start instruction is received. as input, it submits the decoded images to intramode coding. As in the third working example, the image data converter 125 is of the configuration shown in the example of Figure 8. The image data converter 125 at least operates similarly to the case of the third working example. The switch 108 supplies the media synchronization module 109 with image data which has been subjected to intramode coding and which has been supplied from the image data converter 105 at the time of entry of a registration start instruction.

The switch 108 continues to supply the media synchronization module 109 with reception image data 103 from the time the registration was initiated until the entry of an end of registration instruction. The switch 108 further supplies the media synchronization module 109 with audio reception data 104 from the input of the registration start instruction and up to the entry of an end of registration instruction. The media synchronization module 109 confers time information to the audio data and the image data that has been converted and supplies this data to the storage device 110. At this time, the amount of code in image data of the time the recording started, which have been subjected to intramode coding, is usually greater than the amount of code in the image data before conversion. As a result, if the image and speech are synchronized at the beginning of the conversion, the image will be presented with a delay. The media synchronization module 109 therefore adjusts by shifting the audio data again as shown in the hub N in Fig. 6A so that synchronization is established between the image and speech. At this time, if the lack of audio data corresponding to the front image presents problems when they are reproduced, the media synchronization module 109 inserts, for example, silence data as shown in Figure 6B. Fifth Working Example The following explanation concludes the fifth working example with reference to Figure 10. The present working example corresponds to the first modality that is used in the packet switching network (see Figure 2). The data receiver 101 analyzes the received packets 100 that are received from a terminal device, and outputs at least one of the reception control data 102, reception image data 103, reception audio data 104, and data. 116 of DTMF.

The data transmitter 114 at least converts between the transmission control data 111 data transmission data 112, and audio transmission data 113 to packets and then supplies the transmission packets 115. Upon receiving a DTMF signal based on IETF RFC2833 indicating a registration start instruction or an end of registration instruction from a terminal device, the data receiver 101 supplies DTMF data 116 to the DTMF detector 106. The DTMF detector 106 analyzes the DTMF data 116 and then supplies the DTMF signal detection results to the control module 107. When the DTMF signal detection results indicate a registration start instruction, the control module 107 supplies a registration start instruction to the image data converter and switch 108. When the DTMF signal detection results indicate an end-of-registration instruction, the control module 107 supplies the end-of-registration instruction to the image data converter 135 and the switch 108.

The decoding time quantization precision 702 is a parameter obtained when the decoder 701 performs the decoding, and is information that is effective when the coding control is implemented so that the code quantity after coding is determined. approach the 703 amount of reception code. The code quantity control module 805 uses at least one between decoding time quantization precision 702 and receive code quantity 703 to determine the coding time quantization precision 706, and supplies the result to the picture encoder 707 . The code quantity control module 805 after the conversion (1 code quantity when the image encoder 707 has carried out the coding) is the same as the code quantity (allowing a certain amount of error) that the quantity code before the conversion (the amount of code before the decoder 701 performs the decoding). Through this control, synchronization between images and speech is established. The switch 108 shown in Fig. 10 supplies the storage device 110 with image data which has been subjected to intramode coding and which has been supplied from the image data converter 135 at the time of entry of a registration start instruction .

The data multiplexer 214 multiplexes at least one between transmission control data 211, transmission image data 112, and supplies multiplexed transmission data 215. When a registration start instruction or an end of registration instruction is transmitted from a terminal device, the DTMF decoder 206 detects a DTMF signal by analyzing the frequency of the audio signal obtained from the audio reception data 104 and supplies the DTMF signal detection results to the control module 207. When the DTMF signal detection results indicate a registration start instruction, the control module 207 supplies the registration start instruction to the data image converter 105 and switch 108. When the DTMF signal detection results indicate an end-of-registration instruction, the control module 207 supplies the end-of-registration instruction to the image data converter 105 and switch 108.

The switch 108 further supplies the storage device 110 with reception audio data 104 from the entry of the registration start instruction to the entry of an end of registration instruction. Seventh Work Example The explanation below is related to the seventh working example of the present invention with reference to Figure 13. The present working example corresponds to the second mode that is in an on-line switching network (see Figure 3). The data separator 201 separates at least one between the reception control data 202, reception image data 103, and reception audio data 104 of multiplexed reception data 200 that has been multiplexed and received from a terminal device. The reception control data 202 is supplied to the control module 207. The reception image data 103 is supplied to the image data converter 105 and switch 108. The reception audio data 104 is supplied to the DT F detector and switch 108. In order to carry out capacity exchange between the device terminal and the mobile image storage device at the beginning of the communication, the control module 207 supplies the data multiplexer 214 with transmission control data 211 based on H. 245 which is prescribed by IUT-T, and supplies the separator 201 data and data multiplexer 213 with capacity information related to multiplexing and that is contained in the reception control data 202 (such as multiplexing frames and the maximum values of parameters used during the multiplexing of size AL- Multiple SDU, and separation). Based on this capacity information, the data separator 201 separates the multiplexed reception data 200. The data multiplexer 214 multiplexes at least one between transmission control data 211, transmission image data 112 and audio transmission data 113. At the capacity exchange termination, the control module 207 supplies the storage device 110 with a mobile guide image transmission instruction signal indicating the method of operation in the terminal device. When the guide mobile image transmission instruction signal is received as input, the storage device 110 supplies the data multiplexer 214 with data transmission data 112 and audio transmission data 113 corresponding to the guide mobile image. received. The mobile guide image includes, for example, at least one between speech and images that have the content "Please press the number '0' when the registration starts and the number? 1 'when the registration is finished.

The data multiplexer 214 multiplexes at least one between the transmission control data 211, transmission image data 112, and transmission audio data 113 and then supplies multiplexed transmission data 215. When a start registration instruction or an end of registration instruction is transmitted from the terminal device, the DTMF detector 206 analyzes the frequency of the audio signal obtained from the audio reception data 104 for detecting DTMF signals and supplies the DTMF signal detection results to the control module 297. When the DTMF signal detection indicates a registration start instruction, the control module 207 supplies the registration start instruction to the image data converter 105 and switch 108. When the DTMF signal detection results indicate an instruction of end of the image converter converter 105 and switch 108. Upon receiving a registration start instruction as input, the image data converter 105 converts the reception image data 103 at this time into image data that has been subjected to intra-mode coding and supplies the result to the switch 108. In order to carry out this process, the image data converter 105 constantly decodes the reception image data 103 that is received as input, and when an instruction is received. Starting record as input, submit the decoded image to intramode encoding. The switch 108 supplies the media synchronization module 109 with image data which has been subjected to intramode coding and which has been supplied from the image data converter 105 at the time of entry of a registration start instruction. The switch 108 continues to supply the metering data module 109 with reception image data 103 from the time the registration has started until the entry of an end of registration instruction. The media synchronization module 109 confers time information to audio data and image data that has been converted, and supplies this data to the storage device 110. At this time, the amount of code in image data when the record is started, which have been subjected to intramode coding, is usually greater than the amount of code before the conversion. In this case, the synchronization of images and speech at the time of conversion starts results in the delayed presentation of images. In response, the media synchronization module 109 adjusts by shifting the audio data again as shown in frame N in Figure 6A so that synchronization is established between images and speech. At this time, when the lack of audio data for the front image causes problems during playback, the media synchronization module 109 inserts, for example, silence data as shown in Figure 6B. Eighth Working Example The following explanation with respect to the eighth working example of the present invention with reference to Figure 14. The present working example corresponds to the second mode used in an on-line switching network (see Figure 3) . The data separator 201 separates at least one between the reception control data 202, reception image data 103, and reception audio data 104 from the multiplexed reception data that has been multiplexed and received from a terminal device. The reception control data 202 is supplied to the control module 207. The reception image data 103 is supplied to the image data converter and intrupter 108. The audio reception data 104 is supplied to the DTMF detector 206 and switch 108. In order to carry out the capacity exchange between the receiver and the receiver. terminal device and the mobile image storage device at the beginning of the communication, the control module 207 supplies the data multiplexer 214 with transmission control data 211 based on H. 245 as prescribed by ITü-T, and supplies the data separator 201 and data multiplexer 214 with capacity information related to multiplexing and that is contained in the reception control data 202 (the multiplexing frames and the maximum values of parameters used during multiplexing of multiple AL-SDü size and separation). Based on this capacity information, the data separator 201 performs the separation of multiplexed reception data 200. The data multiplexer 214 multiplexes at least one between transmission control data 211, transmission image data 112, and transmission audio data 113. At the termination of the capacity exchange, the control module 207 supplies the storage device 110 with a guidance mobile image transmission instruction signal indicating the method of operation in the terminal device. During the input of the guide mobile image transmission instruction signal the storage device 110 supplies the data multiplexer 214 with transmission image data 112 and transmission audio data 113 corresponding to the moving guide image. The mobile guide image contains, for example, at least one between speech and images that has the content "Please press the number '?' when the registration starts or the number '1' when the registration is finished ". The data multiplexer 214 multiplexes at least one between transmission control data 211, transmission image data 112, and transmission audio data 113 and supplies multiplexed transmission data 216 as output. When a start registration instruction or end of register instruction is transmitted from the terminal device, the DTMF detector 206 analyzes the frequency of the audio signal obtained from the receiving audio data 104 to detect the DTMF signal, and then supplies the DTMF signal detection results to the control module 207. When the DTMF signal detection results indicate a registration start instruction, the control module 207 supplies the registration start instruction to the image data converter 125 and the switch 108. when the DTMF signal detection results indicate an end of registration instruction, the control module 207 supplies the end of registration instruction to the image data converter 125 and switch 108. At the input of a start registration instruction, the image data converter 125 converts the image data of reception at that moment in image data that have been subjected to intramode coding and supplies the result to the switch 108. In order to carry out this procedure, the image data converter 125 constantly decodes the data 103 of reception image that are received as input, and during the entry of a registration start instruction, the images are submitted encoded to intramode coding. As in the third working example, the image data converter 125 is of the configuration shown in FIG. 8, and the operation of the image data converter 125, therefore, is similar to that of the third working example. The switch 108 supplies the storage device 110 with image data which has been subjected to intramode coding and which has been supplied from the image data converter 125 at the time of entry of the start registration instruction. The switch 108 continues to supply the storage device 110 with reception image data 103 from the time the registration was initiated to the entry of an end of registration instruction. The switch 108 further supplies the storage device 110 with reception audio data 104 from the input of a start registration instruction to the entry of an end of registration instruction. Ninth Working Example The following explanation relates to the ninth working example of the present invention with reference to Figure 15. The present working example corresponds to the second embodiment that is used in an on-line switching network (see Figure 3) .. The data separator 201 separates at least one between reception control data 202, data 103 of reception image, and data 104 of audio of reception of the data 200 receiving multiplexes that have been multiplexed and received from a terminal device. The reception control data 202 is supplied to the control module 207. The reception image data 103 is supplied to the image data converter and switch 10- The reception audio data 104 is supplied to the DTMF detector 206 and switch 108. In order to carry out the capacity exchange between the receiver and the receiver. terminal device and the mobile image storage device at the beginning of the communication, the control module 207 supplies data to the multiplexer 214 with the transmission control data 211 based on H.245 as prescribed by ITÜ-T and supplies the separator 201 data and data multiplexer 214 with capacity information related to the multiplexing that is contained in the reception control data 202 (multiplexing frames and the maximum values of parameters used during multiplexing of multiple AL-SDÜ size and separation). Based on this capacity information, the data separator 201 separates the multiplexed reception data 200. The data multiplexer 214 multiplexes at least one between transmission control data 211, transmission image data 112, and transmission audio data 114. At the capacity exchange termination, the control module 207 supplies the storage device 110 with a mobile guide image transmission instruction signal indicating the method of operation in the terminal device. Upon receipt of the guidance mobile image transmission instruction signal, the storage device 110 supplies the data multiplexer 214 with transmission image data 112 and transmission audio data 113 corresponding to the mobile guidance image. The mobile guide image contains, for example, at least one between speech and images that have the content "Please press the number 0 'when the registration starts and the number * 1' when the registration ends". The data multiplexer 214 multiplexes at least one between transmission control data 211, transmission image data 112 and audio data 113 and provides transmission data multiplexed 215 as output. When a start registration instruction or an end of registration instruction is transmitted from a terminal device, the DTMF detector 206 analyzes the frequency of the audio signal obtained from the receiving audio data 104 to detect a DTMF signal and supplies the DTMF signal detection results to the control module 207.

When the DTMF signal detection results indicate a registration start instruction, the control module 207 supplies the registration start instruction to the image data converter and switch 108. When the DTMF signal detection results indicate a end of registration instruction, the control module 207 supplies the end-of-registration instruction to the image data converter 125 and the switch 108. Upon receiving a registration start instruction as input, the image data converter 125 converts the image data of reception at that time in image data that has been subjected to intramode coding and supplies the result to switch 108. In order to carry out this process, the image data converter 105 constantly decodes data 103. that are received as input, and upon receipt of a registration start instruction as input, submit the decoded images to intramode coding. As with the third working example, the image data converter 125 is of the configuration shown in Figure 8, and the image data converter 125, therefore, has the same operation as in the third working example.

The switch 108 supplies the storage device 110 with image data that has been subjected to coding. intramode and that have been supplied from the image data converter 125 at the time of entry of a registration start instruction. The switch 108 continues to supply the storage device 110 with reception image data 103 from the time the registration was initiated to the entry of an end of registration instruction. The switch 108 further supplies the media synchronization module 109 with reception audio data 104 from the input of a register start instruction to the input of an end of register instruction. The media synchronization module 109 confers time information to the audio data and image data that has been converted and supplies this data to the storage device 110. At this time, the amount of code in the image data at the time the registration has started, having been submitted to intramode coding, is usually greater than the amount of code before the conversion. As a result, when speech and images are synchronized at the time you initiated that conversion, the presentation of images is delayed.

The media synchronization module 109 therefore adjusts by moving audio data again as shown in frame N in Figure 6A so that synchronization is obtained between images and speech. At this time, if there is a lack of audio data corresponding to the front images causes problems during playback, the media synchronization module 109 inserts, for example, silence data as shown in Figure 6B.

The reception control data 202 is supplied to the control module 207. The reception image data 103 is supplied to the image data converter and switch 108. The reception audio data 104 is supplied to the DTMF detector 206 and switch 108. In order to carry out the capacity exchange between a terminal device and the mobile image storage device at the beginning of the communication, the control module 207 supplies the data multiplexer 214 with transmission control data 211 based on H.245 as prescribed by ITÜ-T and supplies the separator 201 data and data multiplexer 214 with capacity information related to the multiplexing that is contained in the reception control data 202 (multiplexing frames and the maximum values of parameters used during multiplexing of multiple AL-SDU size and separation). Based on this capacity information, the data separator 201 performs the separation of multiplexed reception data 200. The data multiplexer 214 multiplexes at least one between transmission control data 211, transmission image data 112, and transmission audio data 113. At the capacity exchange termination, the control wire 207 supplies the storage device 110 with a mobile guide image transmission instruction indicating the method of operation in the terminal device. Upon receipt of the guidance mobile image transmission instruction signal as input, the storage device 110 supplies the data multiplexer 214 with transmission image data 112 and transmission audio data 113 corresponding to the moving guide image. The mobile guide image contains, for example, at least one between speech and images that have the content "Please press the number 0 'when the registration starts and the number' 1 'when the registration is finished." As in the case of the fifth working example, the image data converter 135 implements the contri so that the size of the image data after the conversion is the same as the amount of code in the received image data. In other words, the image data converter 135 is of the configuration shown in Figure 11, as with the case of the fifth working example, and t the image data converter 135, therefore has an operation similar to the fifth work example. The switch 108 supplies the storage device 110 with image data which has been subjected to intramode coding and which has been supplied from the image converter 135 at the time of entry of a registration start instruction. The switch 108 continues to supply the storage device 110 with reception image data 103 from the time the registration was initiated to the entry of an end of registration instruction. Switch 108 supplies, in addition to the storage device 110 with audio data 104 of receiving the input of a registration start instruction until the entry of an end of registration instruction. Potential for Use in the Industry The present invention is ideally suited to store mobile image data that is received from a terminal device in a server, such as when mobile image data that is received from a videophone service is stored and distributed or that they are received from a mobile movie distribution service using portable terminals in a line switching network or packet switching network.
