—The brand-new SP-frame in H.264 facilitates drift-free bitstream switching. Notwithstanding the guarantee of seamless switching, the cost is the bulky size of secondary SP-frames. This induces a significant amount of additional space or bandwidth for storage or transmission. In this paper, our investigation reveals that the size of secondary SP-frames is(More)
The distinguishing feature of multiview video lies in the interactivity, which allows users to select their favourite viewpoint. It switches bitstream at a particular view when necessary instead of transmitting all the views. The new SP-frame in H.264 is originally developed for multiple bit-rate streaming with the support of seamless switching. The(More)
The brand-new SP-frame in H.264 facilitates drift-free bitstream switching. Notwithstanding the guarantee of seamless switching, the cost is the bulky size of secondary SP-frames.

Keywords: SP-frame Bitstream switching FMO QDCT domain Motion estimation a b s t r a c t To cope with considerable size of secondary SP-frames, quantized-transform domain motion estimation has recently been proved to be appropriate for the coding of secondary SP-frames in H.264/AVC. Nevertheless, its computational complexity is tremendous and there are(More)
With the proliferation of digital video and the popularity of video streaming applications, it is highly desirable to find and access video segments of interest by searching through the content of video at a speed that is faster than a normal playback. The key functions that enable quick browsing of video are fast-forward and fast-reverse playbacks.(More)
