Description.mpeg (Moving Picture Experts Group) The .mpeg file format is a popular video file format standardized by the Moving Picture Experts Group (MPEG). It is used for audio and video compression and transmission. MPEG files use different compression for audio and video tracks; video is compressed using MPEG-1 or MPEG-2 compression (depending on the quality and purpose), and audio is typically compressed using MP3. MPEG files are commonly used for creating movies that are distributed over the internet due to their high compression and decent quality.
Technical detailsThe `.mpeg` format encompasses various digital video and audio coding formats set by the Moving Picture Experts Group (MPEG). These standards are essential for encoding digital audio and video.
MPEG-1: Aimed at coding progressive video at about 1.5 Mbps, MPEG-1 was used for Video CDs, digital TV, and audio broadcasting. It supports resolutions up to 352x240 (NTSC) or 352x288 (PAL/SECAM) and includes MP3 audio and MPEG-1 Part 2 video components.
MPEG-2: Developed for interlaced images, digital TV, and DVDs, MPEG-2 enhances coding efficiency over MPEG-1. It supports HDTV and includes advanced audio (AAC) and video formats.
MPEG-4: Designed for multimedia streaming, telephony, and broadcast TV, MPEG-4 caters to a range from internet streaming to high-definition TV. It's standard for Blu-ray discs, including MPEG-4 Part 2 and AVC (H.264).
General Aspects:
- MPEG uses lossy compression to minimize data for audio-visual content.
- MPEG files have various extensions like .mpg, .mpeg for video, and .mp3, .aac for audio.
- It employs interframe compression, storing differences between frames to reduce file size.
- MPEG files vary in bitrate, affecting quality and size.
- These files are widely compatible and suitable for internet streaming due to their compression efficiency.
MPEG standards are pivotal in digital video and audio's growth in broadcasting and online streaming, balancing compression efficiency and quality.
