What is the difference between JPEG and MPEG video in digital cameras?
Ok, so I'm doing my first digital camera, and I I know nothing of JPEG and MPEG. Which is better JPEG or MPEG video?
JPEG video similar to a digital still image camera, network camera captures individual images and compresses them into a JPEG file format. The network camera can capture and compress, for example, 30 such individual images per second (30 fps), and then make them available to a continuous flow of images across a network to a viewing station. At a speed of about 16 fps or more, the viewer receives full motion video. We refer to this method as Motion JPEG or M-JPEG. Since each individual image is a complete JPEG compressed image, all have the same quality assurance, determined by the compression level is defined as the network camera or network video server. MPEG simply described, the basic principle MPEG is to compare two compressed images to be transmitted over the network, and use of the compressed image first as a reference frame (called I-frame), only sending party of the images below (By P-frames) that differ from the reference image. The viewing station of the network then rebuild all images based on the reference image and the "difference data" in the By P-frames. Both have their place and usage. I tend to personally prefer MPEG.
