  • Distributed multimedia server system, multimedia information distribution method, and computer product
    Patent number: 9002969
    Abstract: A distributed multimedia server system includes a buffer server module, a storage server module, and an intercluster connection network. Based on memory information on a buffer memory of the storage server module that stores divided multimedia information, the buffer server module obtains the divided multimedia information from the buffer memory using remote direct memory access. The storage server module reads the divided multimedia information requested from the buffer server module from a storage device, and stores the divided multimedia information in the buffer memory.
    Type: Grant

  • Video data playback system using effective scheme for producing coded video data for fast playback mode
    Patent number: 5887110
    Abstract: A video data playback system for reproducing requested video data by switching coded video data to be reproduced between normal playback coded video data and fast playback coded video data according to a requested playback mode, where the normal playback coded video data are encoded by a first video coding scheme using both intra-frame coding and inter-frame coding, while the fast playback coded video data are encoded by a second video coding scheme using only intra-frame coding and having a playback bit rate and a frame rate identical to those of the normal playback coded video data. The normal playback coded video data can be obtained by encoding the original video data first, then the fast playback coded video data can be obtained by encoding selectively decoded normal playback coded video data. Alternatively, the normal and fast playback coded video data can be obtained by synchronizing start and end of encoding by the first video coding scheme and encoding by the second video coding scheme.
