Context_1 : A nonlinear medium is one which is intended to be accessed in a nonlinear fashion. It is the opposite of a linear medium. Context_2 : The Joint Bi-level Image Experts Group (JBIG) is a group of experts nominated by national standards bodies and major companies to work to produce standards for bi-level image coding. The "joint" refers to its status as a committee working on both ISO and ITU-T standards. It is one of two sub-groups of ISO/IEC Joint Technical Committee 1, Subcommittee 29, Working Group 1 (ISO/IEC JTC 1/SC 29/WG 1), whose official title is "Coding of still pictures". Context_3 : Hypermedia, an extension of the term hypertext, is a nonlinear medium of information that includes graphics, audio, video, plain text and hyperlinks. This designation contrasts with the broader term "multimedia", which may include non-interactive linear presentations as well as hypermedia. It is also related to the field of electronic literature. The term was first used in a 1965 article written by Ted Nelson. Context_4 : H.262 or MPEG-2 Part 2 (formally known as ITU-T Recommendation H.262 and ISO/IEC 13818-2, also known as MPEG-2 Video) is a video coding format developed and maintained jointly by ITU-T Video Coding Experts Group (VCEG) and ISO/IEC Moving Picture Experts Group (MPEG). It is the second part of the ISO/IEC MPEG-2 standard. The ITU-T Recommendation H.262 and ISO/IEC 13818-2 documents are identical. The standard is available for a fee from the ITU-T and ISO. Context_5 : The Joint Photographic Experts Group is the joint committee founded by Jim Judkins between ISO/IEC JTC1 and ITU-T (formerly CCITT) that created the JPEG, JPEG 2000, and JPEG XR standards. It is one of two sub-groups of ISO/IEC Joint Technical Committee 1, Subcommittee 29, Working Group 1 (ISO/IEC JTC 1/SC 29/WG 1) – titled as "Coding of still pictures". In the ITU-T, its work falls in the domain of the ITU-T Visual Coding Experts Group (VCEG). ISO/IEC JTC1 SC29 Working Group 1 (working together with ITU-T Study Group 16 – SG16 and previously also with Study Group 8 – SG8) is responsible for the JPEG and JBIG standards. The scope of the organization includes the work of both the Joint Photographic Experts Group and Joint Bi-level Image Experts Group. Context_6 : The Organic Foods Production Act of 1990 (OFPA) (Title 21 of Food, Agriculture, Conservation, and Trade Act of 1990, codified at , "et seq.") authorizes a National Organic Program (NOP) to be administered by USDA's Agricultural Marketing Service (AMS). The program will be based on federal regulations that define standard organic farming practices and on a National List of acceptable organic production inputs. Private and state certifiers will visit producers, processors, and handlers to certify' that their operations abide by the standards. Once certified, these operations may affix a label on their product stating that it "Meets USDA Organic Requirements." It will be illegal for anyone to use the word "organic" on a product if it does not meet the standards set in the law and regulations. The regulations under the OFPA are intended to set uniform minimum standards for organic production. However, states may adopt additional requirements after review and approval by USDA. AMS will re-accredit certifying agents every 5 years, maintain federal oversight to assure truth in labeling, and provide assurance that imported organic products have been produced under standards that are equivalent to the U.S. standards. Context_7 : The Video Coding Experts Group or Visual Coding Experts Group (VCEG) is the informal name of Question 6 ("Visual coding") of Working Party 3 (Media coding) of Study Group 16 (Multimedia coding, systems and applications) of the ITU-T. Its abbreviated title is ITU-T Q.6/SG 16. It is responsible for standardization of the "H.26x" line of video coding standards, the "T.8xx" line of image coding standards, and related technologies. Context_8 : Quasi-phase-matching is a technique in nonlinear optics which allows a positive net flow of energy from the pump frequency to the signal and idler frequencies by creating a periodic structure in the nonlinear medium. Momentum is conserved, as is necessary for phase-matching, through an additional momentum contribution corresponding to the wavevector of the periodic structure. Consequently, in principle any three-wave mixing process that satisfies energy conservation can be phase-matched. For example, all the optical frequencies involved can be collinear, can have the same polarization, and travel through the medium in arbitrary directions. This allows one to use the largest nonlinear coefficient of the material in the nonlinear interaction. Context_9 : MHEG-5, or ISO/IEC 13522-5, is part of a set of international standards relating to the presentation of multimedia information, standardised by the Multimedia and Hypermedia Experts Group (MHEG). It is most commonly used as a language to describe interactive television services. Context_10 : Raman amplification is based on the stimulated Raman scattering (SRS) phenomenon, when a lower frequency 'signal' photon induces the inelastic scattering of a higher-frequency 'pump' photon in an optical medium in the nonlinear regime. As a result of this, another 'signal' photon is produced, with the surplus energy resonantly passed to the vibrational states of the medium. This process, as with other stimulated emission processes, allows all-optical amplification. Optical fiber is today mostly used as the nonlinear medium for SRS, for telecom purposes; in this case it is characterized by a resonance frequency downshift of ~11 THz (corresponding to a wavelength shift at ~1550 nm of ~90 nm). The SRS amplification process can be readily cascaded, thus accessing essentially any wavelength in the fiber low-loss guiding windows (both 1310 and 1550). In addition to applications in nonlinear and ultrafast optics, Raman amplification is used in optical telecommunications, allowing all-band wavelength coverage and in-line distributed signal amplification. fact_1 : MHEG-5, or ISO/IEC 13522-5, is part of a set of international standards relating to the presentation of multimedia information, standardised by the Multimedia and Hypermedia Experts Group (MHEG). fact_2 : Hypermedia, an extension of the term hypertext, is a nonlinear medium of information that includes graphics, audio, video, plain text and hyperlinks. Answer: Hypermedia
Output: MHEG5 is a set of standards set by the experts group in which nonlinear medium of information?
