MPEG-V 3 (SEM) SEM XML,. MPEG-V Binary MPEG format for XML(BiM) gzip. Abstract This paper explains about the structure of multiple sensorial media application format (ISO/IEC 23000-17), which is newly standardized as a project of MPEG-A. This format facilitates effective storage, playing, and management of media with multiple sensorial effects. The ISO base media file format from MPEG-4 Part 12 and sensory effect metadata (SEM) from MPEG-V Part 3 are used to composed the multiple sensorial media application format. In this paper, a fragmentation method to break a SEM XML document into valid SEM samples is presented. Several binarization methods to compress the SEM samples are compared and evaluated as well. The compression ratio and processing time using the MPEG-V binary representation and the Binary MPEG format for XML (BiM) are superior to the gzip compression.
