Moving image communication device, moving image communication system and semiconductor integrated circuit used for communication of moving image

A moving image communication device comprising:

• an encoder for generating encoded data from image data;
• a packet generator for generating a packet from the encoded data and transmitting the generated packet to a network;
• a communication processor for judging whether or not the packet can be transmitted by the packet generator based on communication conditions of the network and generating and transmitting a storage request signal in accordance with a result of the judgment;
• a buffer memory in which the encoded data can be stored;
• and
• a data processor for judging a state where the encoded data is stored in the buffer memory in response to the storage request signal and controlling the encoded data based on a result of the judgment, wherein
• the communication processor sets the storage request signal to be effective when it is judged that the packet cannot be transmitted and sets the storage request signal to be ineffective when it is judged that the packet can be transmitted,
• the data processor makes the buffer memory store the encoded data therein when it is confirmed that the storage request signal is effective;
• the data processor reads the encoded data from the buffer memory and transmits the read encoded data to the packet generator when it is confirmed that the storage request signal is ineffective and the encoded data is stored in the buffer memory, and
• the data processor receives the encoded data from the encoder and transmits the received encoded data to the packet generator when it is confirmed that the storage request signal is ineffective and the encoded data is not stored in the buffer memory.
