Greetings, All! Comment message: Wed Nov 07 2001 00:48, Dmitry Lomov wrote to Sergey Popov: Briefly about the history and characteristics of MPEG standards. MPEG stands for "Moving Picture Coding Experts Group", literally - "Moving Picture Coding Expert Group". MPEG has its own history since January 1988. More precisely, the MPEG group was created by the International organization of standards (International Standards Organization or abbreviated ISO) and the International Electrotechnical Commission (International Electro-Technical Commission or IEC for short). The group was formed to create mobile phone coding standards images and audio information. Since the first meeting in May 1988 the group began to grow and grew into a community of high-level specialists. Typically, an MPEG meeting is attended by about 350 specialists from more than 200 companies. Meetings are held about three times a year. Most MPEG participants are individual specialists engaged in certain scientific and academic institutions. This is from the field of history. Now about practice. To date, MPEG has developed the following standards and algorithms: MPEG-1 (November 1992) - standard for encoding, storage and decoding of mobile images and audio information; MPEG-2 (November 1994) - encoding standard for digital television;MPEG-4 - standard for multimedia applications: version 1 (October 1998) and version 2 (December 1999); MPEG-7 is a universal standard for working with multimedia information, designed for processing, filtering and managing multimedia information. In order. 1) Consider the MPEG-1 package. This kit is in accordance with the standards ISO, includes three algorithms of varying levels of complexity: Layer (level) I, Layer II and Layer III. The general structure of the coding process is the same for all levels. Each level has its own bit stream recording format and its own decoding algorithm. MPEG algorithms are based generally on learned properties perception of sound signals by the human hearing aid (that is, encoding produced using the so-called “psychoacoustic model”). Briefly about the encoding algorithm. The input digital signal is first decomposed to the frequency components of the spectrum. Then this spectrum is cleared of obviously inaudible components - low-frequency noise and highest harmonics, that is actually filtered. At the next stage, much more is produced complex psychoacoustic analysis of the audible frequency spectrum. This is done in number in order to identify and remove frequencies (frequencies that are not are perceived by the hearing aid due to their attenuation by other frequencies).After all these manipulations, more is excluded from the digital audio signal. half the information.

I found the owner of 5.1. Please explain: 5.1 has the same two stereo outputs as and on the previous ones. What's different in it besides the fifth socket (SPDIF/OUT)? Speakers with amplifier are connected to these two stereo outputs, and they have built-in Dolby decoder? The regular blending surround mixer has a 5+1 configuration. You can do it something else?
