The .aac file format

MPEG and MPG are very similar in design and function. MPEG is a more recent format which branches off into standards MPEG-1 all the way through to MPEG-21. They feature a lossy compression that allows for ease of downloading and uploading using smaller file sizes and at the same time retaining high quality. These file storage for audio and visual elements enable the two pieces to remain in sync. MPEG-1 files are maintained for the audio elements while MPEG-2 are for the video/audio elements namely for cable and satellite broadcasts. The MPEG system is a precursor to MP3 file. MPEG-1 and MPEG-2 files are compatible with Mac and Windows due to various programs supporting the files.


.aac technical details

MPEG-1 is for the coding of video and associated audio for storage up to 1.5 Mbits/s (ISO/IEC 11172), but also shows capability for higher bit rates. Therefore MPEG-1 is suitable for encoding to a CD or low-quality DVD video. MPEG-2 conversely is used for broadcast-quality television with high definition features. MPEG-3 handles the standardization of scalable and multi-resolution compression for HDTV but but has been later combined with MPEG-2 due to close resemblance. MPEG-4 attained better rates of compression than MPEG-2 with more efficient coding methods and eventually became useful for rendering computer graphics. MPEG-7 falls under the ISO-IEV 15938 standard, and the MPEG-21 falls under ISO/IEC 21000 standard, setting frameworks for multimedia and allows for copyrights.
