    摘要: In an apparatus for providing a multimedia streaming service, a server transmits a Media Presentation Description (MPD) including information about media data to a client, receives a partial request message requesting a part of media data having a range according to a defined range in the MPD, and transmits to the client a segment having the range in response to the partial request message. The segment includes at least one fragment, segment index information indicating the position of the at least one fragment in the segment, and fragment index information indicating the position of each of a plurality of samples included in the at least one fragment.

    摘要: Disclosed are a distributed video encoding/decoding method and a distributed video encoding/decoding apparatus, which can improve loss resilience and the quality of service. The distributed video encoding method first involves checking the state of a channel, determining a channel coding rate and the size of video data to be transmitted based on the checked state of a channel, determining the number of motion prediction performance steps based on the determined size of video data to be transmitted, encoding the video data to be transmitted by performing motion predictions according to the determined number of motion prediction performance steps, and channel-coding the encoded video data according to the determined channel coding rate. Accordingly, it is possible to improve loss resilience, even without additionally occupying network resources, thereby being capable of reducing the probability of decoding failure.
