Abstract

A communication unit stores information including audio and image information in order to respond to a multiplexed multimedia information signal from another communication unit. In response to the received multiplexed multimedia information signal, the stored image information is transmitted after transmission of the stored audio information.

Claims

1. A communication apparatus for multimedia information, comprising:

reception means for receiving multiplexed multimedia information;

memory means for storing information containing audio information and image information as an automatic response message in an automatic response to a transmission side in accordance with a reception by said reception means; and

transmission means for transmitting image frame data information for use in the automatic response to the transmission side after having transmitted audio frame data information for use in the automatic response in accordance with the reception,

wherein said transmission means establishes one or more connections with a communication apparatus of a communication partner during the transmission of audio data by said transmission means to yield a multi-channel communication link with the communication partner, and

wherein the number of connections established by said transmission means is determined by the capability of the communication apparatus of the communication partner and the type of multimedia information that is to be transmitted as the automatic response message.

2. A communications apparatus according to claim 1, wherein said transmission means transmits the audio frame data information encoded by PCM.

3. A communications apparatus according to claim 1, further comprising storing means for storing said received multiplexed information.

4. A communications apparatus according to claim 1, wherein said memory means stores information for one reception for a predetermined time.

5. A communications apparatus according to claim 1, wherein said transmitted image frame data information is encoded information according to an H.261 codec.

6. A communications apparatus according to claim 1, wherein said transmitted image frame data information is encoded information according to a JPEG encoding method.

7. A communications apparatus according to claim 1, further comprising pick up means for picking up an image, wherein said transmission means transmits said picked up image together with said audio frame data information when an automatic response mode is not set, and

said transmission means transmits only said audio frame data information without said picked up image when the automatic response mode is set.

8. A communications apparatus according to claim 1, further comprising selection means for selecting a response message as the transmitted information transmitted in the automatic response message in response to the multiplexed multimedia information received by said reception means.

9. A communication apparatus according to claim 1, further comprising storage means for storing additional audio and image information which is transmitted from a communication partner after said transmission means has transmitted the stored image frame data information.

10. A communication apparatus according to claim 1, further comprising means for establishing an additional connection with the communication partner according to the presence or absence of an additional connection setting after said transmission means has transmitted the stored image frame data information.

11. A communication method for multimedia information, comprising the steps of:

receiving multiplexed multimedia information;

storing information containing audio information and image information as an automatic response message in an automatic response to a transmission side in accordance with a reception in said receiving step; and

transmitting image frame data information for use in the automatic response to the transmission side after having transmitted audio frame data information for use in the automatic response in accordance with the reception,

wherein, in said transmission step, one or more connections with a communication apparatus of a communication partner are established during the transmission of audio data in said transmission step to yield a multi-channel communication link with the communication partner, and

wherein the number of connections established in said transmission step is determined by the capability of the communication apparatus of the communication partner and the type of multimedia information that is to be transmitted as the automatic response message.
