What is MPEG-4?


MPEG-4 AVC/H.264 is a licensed video compression standard. It saw designed to achieve a high degree of video stream compression while maintaining high quality.

This standard contains a number of new features that significantly improve the efficiency of video compression compared to previous standards. While also providing greater application flexibility in a variety of network environments.

Its main advantage over the previous standard MPEG-4 is the ability to include pictures, text, and three-dimensional images in the structure of the processed media file. In addition, MPEG4 technologies largely focus on applications. Not only by professional recording and video editing studios but also by ordinary users.


Digital satellite television uses the MPEG-2 format, where, with a frame resolution of 720×576 pixels. The information flow rate is 30 frames / sec. is about 12 Mbps, but in practice, a flow rate of about 3 Mbps is used. With a standard bandwidth of 54 MHz, 18 channels usually fit on one satellite transponder. When broadcasting in HDTV, the image resolution is 1920×1080 pixels, which is 5 times higher compared to conventional SD TV, and for broadcasting one HDTV channel in the MPEG-2 standard, the operator would need to rent almost a third of the transponder.

Are MP4 and MPEG4 the same thing?

MPEG 4 is one of the latest audio and video compression methods that has been standardized by the MPEG group. It has been specially designed for low bandwidth (below 1.5Mbps) audio and video encoding processes.

MP4 is an abbreviation for MPEG4 Part 14, not MPEG4. MP4 is the format and file extension for videos. You can use this container format to store audio and video data, as well as images, subtitles, and other similar data. It uses .h264 or .mpeg4 video codec and audio formats like MP3, AAC, and others.
