Examples of Using MPEG in a Sentence

• The Moving Picture Experts Group (MPEG) is an alliance of working groups established jointly by ISO and IEC that sets standards for media coding, including compression coding of audio, video, graphics, and genomic data; and transmission and file formats for various applications.
• Systems (defining a format for storage and synchronization of video, audio, and other data together in a single file—later dubbed the MPEG program stream to distinguish it from the MPEG transport stream format introduced as an alternative in MPEG-2).
• MPEG-3 was the designation for an abandoned plan to create a group of audio and video coding standards agreed upon by the Moving Picture Experts Group (MPEG) designed to handle HDTV signals at 1080p in the range of 20 to 40 megabits per second.
• It was originally introduced in late 1998 as a group of audio and video coding formats and related technology agreed upon by the ISO/IEC Moving Picture Experts Group (MPEG) (ISO/IEC JTC 1/SC29/WG11) under the formal standard ISO/IEC 14496 – Coding of audio-visual objects.
• The player features an optimized version of the Xing MPEG decoder, a powerful music browser and playlist editor, and a built in download manager which supports downloading files from sites using the RMP (RealJukebox) download process.
• Standardized interoperability specifications such as the video coding standards produced by the MPEG and the ITU-T, and the audio coding standards produced by the MPEG, often specify only the bitstream format and the decoding process.
• mpg123's Assembly code is optimized with SIMD instructions to improve the performance of the iDCT part of the MPEG decoding.
• MPEG-7 is intended to complement the previous MPEG standards, by standardizing multimedia metadata -- information about the content, not the content itself.
•  601 video raster format has been re-used in a number of later standards, including the ISO/IEC MPEG and ITU-T H.
• DigiCipher 2 also extends the MPEG program number that is assigned for each service in a transport stream with the concept of a virtual channel number, whereas the DVB system never defined this type of remapping preferring to use a registry of network identifiers to further differentiate program numbers from those used in other transport streams.
• 264 was standardized by the ITU-T Video Coding Experts Group (VCEG) of Study Group 16 together with the ISO/IEC JTC 1 Moving Picture Experts Group (MPEG).
• While the actual DVB-S standard only specifies physical link characteristics and framing, the overlaid transport stream delivered by DVB-S is mandated as MPEG-2, known as MPEG transport stream (MPEG-TS).
• This system transmits compressed digital audio, digital video and other data in an MPEG transport stream, using coded orthogonal frequency-division multiplexing (COFDM or OFDM) modulation.
• Source coding and MPEG-2 multiplexing (MUX): video, audio, and data streams are multiplexed into an MPEG program stream (MPEG-PS).
• It is also compatible with MPEG 4 cameras, AVCHD camcorders, HDV cameras, and Apple's iSight webcams.
• In North America, DVB-T, precisely the same modulation technique as European Broadcast, is used, using a constellation of QPSK, 16QAM, or 64QAM, enabling sufficient digital bandwidths at 6 MHz deviation for transmission of an MPEG transport stream at 10 or more megabits per second, producing three "lower", "center", and "upper" overlapping 6 MHz channels within each 12 MHz channel.
• The DCT is the most widely used lossy compression algorithm, the basis for multimedia formats such as JPEG, MPEG and MP3.
• More-advanced TV tuners encode the signal to Motion JPEG or MPEG, relieving the main CPU of this load.
• Cinepak is based on vector quantization, which is a significantly different algorithm from the discrete cosine transform (DCT) algorithm used by most current codecs (in particular the MPEG family, as well as JPEG).
• To achieve the high performance needed for mathematically intensive tasks, such as decoding/encoding MPEG streams, generating or transforming three-dimensional data, or undertaking Fourier analysis of data, the Cell processor marries the SPEs and the PPE via EIB to give access, via fully cache coherent DMA (direct memory access), to both main memory and to other external data storage.
