We are thrilled to welcome readers to the lawsuits of the sixth Pacific-Rim convention on Multimedia (PCM). the 1st PCM was once held in Sydney, Australia, in 2000. seeing that then, it's been hosted effectively by means of Beijing, China, in 2001, Hsinchu, Taiwan, in 2002, Singapore in 2003, and Tokyo, Japan, in 2004, and eventually Jeju, some of the most appealing and very good islands in Korea. This yr, we accredited 181 papers out of 570 submissions together with common and detailed consultation papers. The popularity cost of 32% exhibits our dedication to making sure a truly top of the range convention. this is able to now not be attainable with out the whole help of the wonderful Technical Committee and nameless reviewers that supplied well timed and insightful experiences. we might for that reason prefer to thank this system Committee and all reviewers. this system of this 12 months displays the present pursuits of the PCM’s. The permitted papers conceal a number of subject matters, together with, all facets of multimedia, either technical and creative views and either theoretical and sensible concerns. The PCM 2005 application covers educational classes and plenary lectures in addition to standard displays in 3 tracks of oral periods and a poster consultation in one song. we've attempted to extend the scope of PCM to the inventive papers which needn't to be strictly technical.

Sample text

Finally, we conclude the paper in Section 6. 2 Related Works With the explosive usage of various computing devices providing multimedia services, there have been studies on caching in these environments in recent years. Dan et al. proposed a caching scheme for video-on-demand servers named interval caching that exploits temporal locality of accessing the same object consecutively [14]. The interval caching policy organizes all consecutive request pairs by increasing order of memory requirements.

Then, the adjusted value should be close to the original value when tn is small, and it should be large enough when tn becomes large. The following adjustment function satisfies these requirements. (2) is replaced by VI n ' = f n ⋅ VI n and the adjustment function is invoked periodically. (4) 6 T. Kim, H. Bahn, and K. Koh As mentioned in Section 1, each multimedia object has its own streaming rate and even a single object may have multiple QoS versions for servicing different appliances. In terms of the hit rate, caching an interval with a higher streaming rate is more efficient when buffer requirements are identical.

1 Introduction In the recent years, the demand of video service over the network has been increasing very fast, and it is feasible due to the fast development of network and digital video processing technologies. Generally, video needs a larger amount of data compared with other media. Thus, it is indispensable to employ the effective video compression algorithm to reduce the amount of data. So far, digital video coding techniques have advanced rapidly. 264 [5] have been established or under development to accommodate different needs by ISO/IEC and ITU-T, respectively.
