    • The client's screen includes a shared area that displays a portion of the server's screen information. The present invention performs a remote event from the client upon the server by causing an input event that is instigated upon the shared area thereof to be replayed upon the server. When this circumstance occurs, the client detects the instruction for the transfer of data to the shared area thereof, requests the transfer of data from the server, receives the data that is thereby transferred from the server, and develops the data thus received to the client's memory space. Upon receipt of the request for transfer of data from the client, the server converts the data that is stored within the server's own memory space into a state wherein the data thus stored is capable of being transferred, and transmits the data thus converted to the client.

In the terminal A, the editing information by that time is held, and when the data object is restored, the held editing information is transmitted to the other terminals. Then the initial display status is restored in the other terminals.

    • Disclosed are an audio encoding device and an audio decoding device which reduce degradation of subjective quality of a decoding signal caused by power mismatch of a decoding signal which is generated by a concealing process upon disappearance of a frame. When a frame is lost, a past encoding parameter is used to obtain a concealed LPC of the current frame and a concealed sound source parameter. A normal CELP decoding is performed from the obtained concealed sound source parameter. Correction is performed by using a conceal parameter on the obtained concealed LPC and the concealed sound source signal. The power of the corrected concealed sound source signal is adjusted to match a reference sound source power. A filter gain of the synthesis filter is adjusted so as to adjust the power of a decoded sound signal to the power of a decoded sound signal during an error-free state. Moreover, a synthesis filter gain adjusting coefficient is calculated by using an estimated normalized residual power so that a filter gain of a synthesis filter formed by using a concealed LPC is a filter gain during an error-free state.

    • An audio decoding device capable of suppressing an information amount for a lost flame compensation process and encoding efficiency is provided. A decoded sound source generator generates a lost frame's CELP decoded sound source signal. A pitch pulse information decoder CELP decodes a pitch pulse position information and a pitch pulse amplitude information. A pitch pulse waveform learner learns a pitch pulse learning waveform in a past frame in advance from the lost frame. A convolution adjuster amplitude-adjusts the pitch pulse learning waveform according to the pitch pulse amplitude information by considering a predetermined number of waveforms peripheral to a peak position of the lost frame's CELP decoded excitation signal, and convolutes a pitch pulse waveform into a time axis which has been amplitude-adjusted according to the pitch pulse position information. A sound source signal corrector adds or replaces the pitch pulse waveform convoluted into the time axis to the lost flame decoded sound source signal.

    • There is provided an audio encoding device capable of causing a decoding side to freely select an audio decoding mode corresponding to a control method used for audio encoding and capable of generating data which can be decoded even when the decoding side does not correspond to the control method. The audio encoding device (100) outputs encoded data corresponding to an audio signal containing an audio component and encoded data corresponding to an audio signal containing no audio component. An audio encoding unit (102) encodes the input audio signal in a predetermined section unit and generates encoded data. An audio present/absent judgment unit (106) decides whether the input audio signal contains an audio component for each predetermined section. A bit embedding unit (104) performs synthesis of noise data only for those generated from the input audio signal of the voice absent section in the encoded data generated by the audio encoding unit (102), thereby acquiring encoded data corresponding to an audio signal containing an audio component and encoded data corresponding to an audio signal containing no audio component.
