Abstract: There are provided a content data transmission method, device, and program that minimize serious disturbances in reproduced content on the reception side, caused by a transmission error of encoded data, without sending feedback information from the reception side to the transmission side. When an encoder 103 creates encoded data to be distributed, the encoder creates plural items of encoded data at the same time or creates FEC data at the same time in advance and, when storing the data in a file 104, stores the data as if the data were one item of encoded data. When a distribution server 105 distributes the data using the file 104, the plurality of items of encoded data are automatically distributed at the same time and the FEC data is distributed. A client 106 receives the plurality of items of encoded data or the FEC data to reduce the probability of data shortage due to a packet loss and, as a result, the deterioration in the image quality and the audio quality is reduced.

Abstract: A conversion server and a plurality of clients are connected via a transmission line. The conversion server that receives image coded data from the clients converts the image coding system in accordance with the coding system available to each client, the coding setting, and the status of the transmission line, and transmits the converted image coded data. For a client where the number of images that can be displayed is limited, the conversion server decodes a selected plurality items of image coded data, re-encodes the selected pieces into one composite image, and transmits the re-encoded image. The conversion server also comprises decoding processing units, one for each connected client, for decoding image coded data from each client. In response to a display image switching request from a client, the conversion server intraframe-codes the decoded image data of an image that will be used after the switching and transmits the intraframe-coded data. This enables an image to be switched quickly independently of the intraframe time of received image coded data that will be used after the switching.
