  • Adaptive media encoding and decoding equipment
    Patent number: 7437285
    Abstract: An encoding unit encodes data at a first rate during an initial predetermined section of uncompressed data (a), and encodes data at a second rate after the initial predetermined section (where the first rate<the second rate), and encoded data are stored in a storage. The storage is read out the stored data to a network at a transmission rate equal to the transmission rate of the network. A decoding unit decodes received data at the first rate during an initial predetermined section, and decodes received data at a second rate after the initial predetermined section. For finite contents, receiving completion and decoding completion of the received data are simultaneous. In accordance with the present invention, while tolerance with respect to data incoming fluctuations is ensured, playback of dynamic images and music and the like can be immediately started after receiving.
