ISO/IEC 23001 (MPEG systems technologies) Part 1, also called Binary MPEG format for XML or BiM, provides a standardized set of generic technologies for encoding XML documents. It addresses a broad spectrum of applications and requirements by providing generic methods for transmitting and compressing XML documents.
Although originally based on the use of XML Schema information, the BiM format now has an efficient mode without schema, as of its Amendment 2. It also features a built-in update mechanism, low memory footprint and high processing speed because it does not require regenerating and parsing XML at the decoder, and it supports forward compatibility. Moreover, it has been widely adopted in several standardization bodies:
MPEG: for encoding MPEG-4, MPEG-7 and MPEG-21 descriptions, as specified in ISO/IEC 15938-1 (MPEG-7 Systems), ISO/IEC 21000-16 (MPEG-21 Binary Format), ISO/IEC 14496-20 (MPEG LASeR) and ISO/IEC 23000-3 (MPEG Photo Player Application format)
TV-Anytime Forum: in ETSI TS 102 822, for encoding the Electronic Program Guide
ARIB: ARIB-STD B38, for coding, transmission and storage specification
DVB: in ETSI TS 102 323 for encoding EPG information over DVB-S/-T/-C; in ETSI TS 102 034 and TS 102 539 over IPTV; and recently in ETSI TS 102 471 for encoding ESG information in IPDC over DVB-H.
BiM is already deployed in many commercial services such as Mobile TV over DVB-H in Italy and IPTV in Japan.
JTC1/SC29/WG 11 believes that BiM responds efficiently to most of technical requirements from the industry in this area, is widely adopted and deployed. If further optimization and/or extensions of the technology are deemed necessary, WG11 believes they can efficiently be done within MPEG whose constituency has grown expertise in the area in the last ten years and as much as possible in the framework of the BiM in order to prevent confusing the industry.
