Apparatus and method for compression-transmitting and decoding picture information and storage medium stored its control programs

A real-time picture information compression-transmission method for compression-transmitting picture information in a real-time manner, comprising:

• an encoding step of encoding said picture information on a preset cycle in a real time manner;
• a storage step of writing and storing real-time-encoded frame data on said picture information for each frame;
• a division step of sequentially dividing said real-time-encoded data into packets for each frame;
• and
• a transmission timing control and transmission step of controlling transmission timing to sequentially transmit the divided packets to a network during an entire period between when said storage step of writing and storing real-time encoded data for a frame ends and when said storage step of writing and storing real-time encoded data for a next frame begins, and of transmitting the packets to the network according to a connection-less type protocol.

A real-time picture information compression-transmission apparatus for compression transmitting picture information in a real-time manner, comprising:

• input means for receiving said picture information;
• an encoder encoding frames of said picture information from the input means on a preset cycle in a real-time manner and outputting real-time-encoded data corresponding to respective frames of said picture information;
• storage means for storing said real-time-encoded data corresponding to the respective frames of said picture information output from the encoder, the encoder writing the real-time-encoded data corresponding to the respective frames into the storage means;
• division means for receiving the real-time encoded data corresponding to respective frames from the storage means and sequentially dividing said real-time-encoded data corresponding to the respective frames into packets;
• and
• transmission timing control and transmission means for controlling transmission timing to sequentially transmit the packets corresponding to the respective frames to a network, wherein the transmission timing and control means controls transmission of packets corresponding to respective frames to the network based on a determination of a difference between a time between frames and a time during which the encoder writes frame data to the storage means, and for transmitting the packets to the network according to a connection-less type protocol.
