Abstract(in English) A number of digital video contents have been used through various media such as optical disc storage, digital television, and Internet. Moreover, DVD/HDD recorders are widespread and growing in capacity to store more contents. Such a situation causes strong demands for novel systems utilizing large amount of digital video streams including simultaneous video browsing and video search systems. In this paper, an implementation of simultaneous video decoding on Cell Broadband Engine is reported aiming at at multiple video display systems. By introducing a set of mechanisms to reduce decoding complexity, simultaneous decoding of 40 MPEG-2 HL (1,920×1,080) streams is attained.
