摘要： Two-way communication devices (101, 103) communicating through a transmission channel (102) each have an encoding section, decoding section and at least either a combination of an interleaver and a deinterleaver or a combination of an error correction encoding section and a decoding section. Each of the two-way communication devices can asymmetrically through transmission/reception set the interleaving unit and interleaving order, or the error-correction encoding method, error generation code generation unit, encoding rate, frame rate, and sampling frequency and communicate depending on the state of the transmission channel (102), the delay request of the user, and the quality request.

摘要： An image data communication system where data missing during a handover peri od is suppressed while preventing the network resources from becoming short. Th e system comprises an image data delivery device (101) that sequentially at a predetermined time interval delivers image encoded data (1, 2) produced by encoding the same image and an image data reception device (107) that receives, while moving across a plurality of wireless areas, the image encod ed data (1, 2) delivered from the image data delivery device (101). At a handov er time at which the image data reception device (107) moves from the current wireless area to another neighboring wireless area, it receives for a predetermined period the image encoded data (1, 2) delivered from the image data delivery device (101) at the predetermined time interval and selects necessary data from the received image encoded data (1, 2) to restructure da ta on one moving image.

摘要： A PTT server includes a controlling unit, a receiving unit, a medium converting unit, and a transmitting unit. The controlling unit controls pieces of connection setting information less than the number of a plurality of PTT terminals having different specifications by complying them with the plurality of PTT terminals. The receiving unit receives a medium coded data from any one of the PTT terminals. The medium converting unit converts the medium coded data with a converting method on the basis of the connection setting information compliant with a PTT terminal for transmission destination to produce an output coded data. The transmitting unit transmits the output coded data to the PTT terminal for the transmission destination.
