摘要:
This invention is to enable transfer of a right to speak in an audio teleconference in view of usability. In this invention, a PoC server is introduced to achieve new functions, such as transfer of the right to speak, reservation to acquire the right to speak, and deprivation of the right to speak. The PoC server has a teleconference presence manager, a teleconference manager, and a teleconference audio communication manager. The right to speak is managed in a presence data storage of the teleconference presence manager. The teleconference presence manager directly manages the presence data storage, but the teleconference manager manages transfer of the right to speak. In addition, the teleconference manager manages reservation of the right to speak by a storage for a reservation list of the right to speak. The teleconference audio communication manager carries out routing of audio data. At that time, only audio data received from a user holding the right to speak is transferred.
摘要:
A communication apparatus going to acquire transmission right accepts input of specifying a communication apparatus as a main target of output among other communication apparatuses, and then performs multi-address calling of output data to the other communication apparatuses. At executing output processing on the basis of the output data, the specified communication apparatus executes output processing such as image output and voice output for notifying the fact of being specified. In a system of PoC service or the like where one communication apparatus among a plurality of communication apparatuses acquires transmission right of transmitting voice data, and then performs multi-address calling of voice data to a plurality of the other communication apparatuses, it is avoided that a target person of speech who is a main target of transmission of voice data among all users operating the other communication apparatuses fails to listen to a speech.
摘要:
A communication control method of this invention includes: when a call-in request to a chat for another participant in a voice-based teleconference by a first participant of the voice-based teleconference is received, transmitting the call-in request to the chat to a terminal of another participant; and when a participation response to the chat by another participant is received, carrying out a presence management setting so as to enable the first participant and a participant replying the participation response to update and subscribe dialogue contents of the chat, which are managed as presence data delivered to subscribers when updated. Thus, by using the presence technique, it becomes possible that the conference is shifted from the voice-based teleconference to the character-based teleconference and both of the conferences coexist.

摘要:
A reception-process manager of a call server writes, in a transfer-voice-data storage, voice data contained in a voice packet received from the transmitter terminal which has acquired the talk right. A transmission-process manager of the call server determines the next transmission interval of a voice packet for each receiver terminal on the basis of determination information received from the each receiver terminal. The transmission-process manager reads out the voice data in a size dependent on the determined transmission interval from the transfer-voice-data storage, generates voice packet containing the voice data for the each receiver terminal, and transmits the voice packet to the each receiver terminal. Thus, the voice-packet transmission interval can be changed for each receiver terminal without stopping voice-packet transmission.

摘要:
A data output apparatus accumulates received sound data in an accumulating unit (jitter buffer), and reproduces sound based on the accumulated sound data. Then, for a predetermined period of time from the time point at which reception of data starts, the data output apparatus restricts or prohibits discarding of data based on an upper accumulation limit amount as a basis for discarding the accumulated data. Moreover, prior to starting reception of sound data after a transfer of a transmission right, dummy data such as soundless data is accumulated in the accumulating unit. Further, the set values of the upper accumulation limit amount, etc. optimized in the previous communication are stored, and the settings stored in association with a transmitting source apparatus are set as the upper accumulation limit amount, etc. after the transfer of the transmission right.
摘要:
The input unit stores data input by the user in the data storage. The status determiner determines reception status of the screen data to be one of three statuses of “abnormal”, “normal”, and “recovery” from “abnormal” to “normal” on the basis of frame losses. In a case of the “abnormal” status, a transmission controller does not read the input data stored in the data storage. In a case of the “normal” status, the transmission controller reads the input data stored in the data storage, transmits the input data via the transmitter, and deletes the input data stored in the data storage. In a case of the “recovery” status, the transmission confirmer instructs the output unit to output the input data stored in the data storage to ask the user whether to transmit the input data to the server.
