Barco projectors choose channels according to films, what are JPEG and MPEG respectively,

The narrowest part of the passage should be greater than 102cm, the narrowest part of the projection room door/stairs should be greater than 80cm, and the turning space should be 130cm.

JPEG is a common image format, which was developed by Joint Photographic Experts Group. The extension of JPEG files is. Jpg or. Jpeg, which uses lossy compression to remove redundant image and color data, can display very rich and vivid images at the same time, that is, it can obtain better image quality with less disk space.

MPEG (Moving Picture Expert Group) is an organization established by ISO and IEC in 1988, which formulates international standards for moving pictures and voice compression.

Extended data

The commercial application fields of MPEG-4 include: digital TV, real-time multimedia monitoring, low bit rate mobile multimedia communication, multimedia system based on content storage and retrieval, network video streaming and visual games, network conference, interactive multimedia application, visual collaborative laboratory scene application based on computer network, radio and television, etc.

The algorithm is specially designed for low bandwidth, so the compression ratio of MPEG4-4 is higher, which makes it possible to transmit video at low bit rate. Video can be transmitted continuously on public telephone lines, and the image quality can be maintained, which can not be achieved by other technologies.

Photographic works or realistic works support advanced compression, file size can be controlled by variable compression ratio, support interleaving (for progressive JPEG files), and widely support Internet standards. Because of its small size, JPEG pictures are used to store and transmit photos on the World Wide Web.
