• MPEG audio supports sampling frequencies of , . and KHz. • Supports one or two audio channels in one of the four modes: Monophonic — single audio channel. Dual-monophonic — two independent channels (functionally identical to stereo). Stereo — for stereo channels that share bits, but not using joint-stereo coding.

MPEG standards address audio and video formats used online, in television broadcasts, and in DVD media. MPEG can be used to store movies on VCDs. A number of MPEG standards are in current use, and more are sure to follow. Some well-known standards are explained briefly below. MPEG-2 is widely used for satellite communication.

MPEG-1: The most common implementations of the MPEG-1 standard provide a video resolution of 352-by-240 at 30 frames per second (fps). This produces video quality slightly below the quality of conventional VCR videos. MPEG-2: Offers resolutions of 720×480 and 1280×720 at 60 fps, with full CD-quality audio. This is sufficient for all the major TV standards, …

The opinion reveals some interesting facts about the relationship between the patent owners (i.e. Philips) and Audio MPEG/Sisvel. Some highlights: although Audio MPEG is a subsidiary of Sisvel, the master agreement is between the patent holders and Audio MPEG. Audio MPEG has granted a sublicense to Sisvel for the European patents.

The MPEG1 audio [1] becomes a popular algorithm for audio data compression due to its high quality with various compression rate, sampling rate and mode. In addition to these variety choices, the MPEG1 is classi-fied into 3 different layers by its complexity. It can compress 1.5Mbit/sec CD quality audio data into 32 to 448 Kbit/sec for layer I
