Moving Picture Experts Group

The Moving Picture Experts Group is a working group of authorities, formed by ISO and IEC to set standards for audio and video compression and transmission. It was established in 1988 by the initiative of Hiroshi Yasuda and Leonardo Chiariglione, group Chair since its inception; the first MPEG meeting was in May 1988 in Canada. As of late 2005, MPEG has grown to include 350 members per meeting from various industries and research institutions. MPEG's official designation is ISO/IEC JTC 1/SC 29/WG 11 – Coding of moving pictures and audio. Joint Video Team is joint project between ITU-T SG16/Q.6 – VCEG and ISO/IEC JTC 1/SC 29/WG 11 – MPEG for the development of new video coding recommendation and international standard. It was formed in 2001 and its main result has been H.264/MPEG-4 AVC. Joint Collaborative Team on Video Coding is a group of video coding experts from ITU-T Study Group 16 and ISO/IEC JTC 1/SC 29/WG 11, it was created in 2010 to develop High Efficiency Video Coding, a new generation video coding standard that further reduces the data rate required for high quality video coding, as compared to the current ITU-T H.264 / ISO/IEC 14496-10 standard.

JCT-VC is co-chaired by Gary Sullivan. Joint Video Exploration Team is a joint group of video coding experts from ITU-T Study Group 16 and ISO/IEC JTC 1/SC 29/WG 11 created in 2017 after an exploration phase in 2015, it seeks to develop Versatile Video Coding. Like JCT-VC, JVET is co-chaired by Gary Sullivan; the MPEG standards consist of different Parts. Each part covers a certain aspect of the whole specification; the standards specify Profiles and Levels. Profiles are intended to define a set of tools that are available, Levels define the range of appropriate values for the properties associated with them; some of the approved MPEG standards were revised by amendments and/or new editions. MPEG has standardized ancillary standards. All of the MPEG formats listed below use discrete cosine transform based lossy video compression algorithms. MPEG-1: Coding of moving pictures and associated audio for digital storage media at up to about 1.5 Mbit/s. This initial version is known as a lossy fileformat and is the first MPEG compression standard for audio and video.

It is limited to about 1.5 Mbit/s although the specification is capable of much higher bit rates. It was designed to allow moving pictures and sound to be encoded into the bitrate of a Compact Disc, it can be used for low-quality video on DVD Video. It was used in digital satellite/cable TV services. To meet the low bit requirement, MPEG-1 downsamples the images, as well as uses picture rates of only 24–30 Hz, resulting in a moderate quality, it includes the popular MPEG-1 Audio Layer III audio compression format. MPEG-2: Generic coding of moving pictures and associated audio information. Transport and audio standards for broadcast-quality television. MPEG-2 standard was broader in scope and of wider appeal – supporting interlacing and high definition. MPEG-2 is considered important because it has been chosen as the compression scheme for over-the-air digital television ATSC, DVB and ISDB, digital satellite TV services like Dish Network, digital cable television signals, SVCD and DVD Video, it is used on Blu-ray Discs, but these use MPEG-4 Part 10 or SMPTE VC-1 for high-definition content.

MPEG-3: MPEG-3 dealt with standardizing scalable and multi-resolution compression and was intended for HDTV compression but was found to be redundant and was merged with MPEG-2. MPEG-3 is not to be confused with MP3, MPEG-1 or MPEG-2 Audio Layer III. MPEG-4: Coding of audio-visual objects. MPEG-4 provides a framework for more advanced compression algorithms resulting in higher compression ratios compared to MPEG-2 at the cost of higher computational requirements. MPEG-4 supports Intellectual Property Management and Protection, which provides the facility to use proprietary technologies to manage and protect content like digital rights management, it supports MPEG-J, a programmatic solution for creation of custom interactive multimedia applications and many other features. Several new higher-efficiency video standards are included, notably: MPEG-4 Part 2 and MPEG-4 AVC. MPEG-4 AVC may be used on HD DVD and Blu-ray Discs, along with VC-1 and MPEG-2. MPEG-4 has been chosen as the compression scheme for over-the-air in Brazil, based on original digital television from Japan.

In addition, the following standards, while not sequential advances to the video encoding standard as with MPEG-1 through MPEG-4, are referred to by similar notation: MPEG-7: Multimedia content description interface. MPEG-21: Multimedia framework. MPEG describes this standard as a multimedia framework and provides for intellectual property management and protection. Moreover, more than other standards above, MPEG has started following international standards. MPEG-A: Multimedia appl

Hallen A.F.C.

Hallen Association Football Club is a non league football club based in Hallen, near Bristol, England. Affiliated to the Gloucestershire County FA, they are members of the Western League Premier Division and play at the Hallen Centre; the club was established in Lawrence Weston in 1949 under the name Lawrence Weston Athletic. They joined the Bristol & District Football League moving up to the Avon Premier Combination, which became the Bristol Premier Combination. In 1979 the club relocated to Hallen in order to meet the league's ground grading requirement and were renamed Lawrence Weston Hallen. In 1982 Lawrence Weston Hallen gained promotion to the Gloucestershire County League, they were runners-up in 1987–88 and won the league the following season. In 1989–90 the club won the Gloucestershire Challenge Trophy, at the end of the season the club adopted their current name. After winning both the Gloucestershire County League and the Gloucestershire Challenge Trophy in 1992–93, they were promoted to Division One of the Hellenic League.

The club were Division One runners-up in earning promotion to the Premier Division. In 2000 Hallen transferred to the Western League. However, they were promoted to the Premier Division. In 2009–10 the club won the league's Les Phillips Cup, they won the Gloucestershire Challenge Trophy for a third time in 2013–14. The club played at Kingsweston House, a former army camp, with a disused nissen hut turned into changing rooms; the ground was rented from Bristol City Council, who installed changing rooms in the basement of the House. When the site was needed by Bristol College of Technology, the club were moved to St Bedes playing fields in Lawrence Weston; the club moved to the Hallen Centre on Moorhouse Lane in 1979 in order to meet ground grading requirements. In the mid-1990s floodlights were erected and the 200-seat Frank Fairman Stand was built.

Johann Friedrich Pfaff

Johann Friedrich Pfaff was a German mathematician. He was described as one of Germany's most eminent mathematicians during the 19th century, he was a precursor of the German school of mathematical thinking, which under Carl Friedrich Gauss and his followers determined the lines on which mathematics developed during the nineteenth century. He received his early education at the Carlsschule, where he met Friedrich Schiller, his lifelong friend, his mathematical capacity was noticed during his early years. He pursued his studies at Göttingen under Abraham Gotthelf Kästner, in 1787 he went to Berlin and studied practical astronomy under J. E. Bode. In 1788, Pfaff became professor of mathematics in Helmstedt, continued his work as a professor until that university was abolished in 1810. After this event, he became professor of mathematics at the University of Halle, where he stayed for the rest of his life, he studied mathematical series and integral calculus, is noted for his work on partial differential equations of the first order Pfaffian systems, as they are now called, which became part of the theory of differential forms.

He knew Gauss well, when they both lived together in Helmstedt in 1798. August Möbius was his student, his two principal works are Disquisitiones analyticae maxime ad calculum integralem et doctrinam serierum pertinentes and “Methodus generalis, aequationes differentiarum particularum, necnon aequationes differentiales vulgares, utrasque primi ordinis inter quotcumque variabiles, complete integrandi” in Abhandlungen der Königlichen Akademie der Wissenschaften zu Berlin. His brother Johann Wilhelm Andreas Pfaff was a professor of applied mathematics. Another brother, Christian Heinrich Pfaff, was a professor of medicine and chemistry.
