MPEG , MPEG Picture Structure and SMPTE


The Moving Picture Experts Group (MPEG) develops standards for digital video and digital audio compression. It operates under the auspices of the International Organization for Standardization (ISO). To use MPEG video files, you need a personal computer with sufficient processor speed, internal memory, and hard disk space to handle and play the typically large MPEG file (which has a file name suffix of .mpg). You also need an MPEG viewer or client software that plays MPEG files. You can download shareware or commercial MPEG players from a number of sites on the Web.

MPEG picture structure
A MPEG Picture consists of a field or a frame. It's identified in the bit stream by the picture header that specifies the picture structure and the picture coding type. There are three (3) types of MPEG picture as the following:
Intra picture ( I_picture) refers to a picture which has no reference to any other picture, but it can be used as a reference for other pictures.
Predicted picture (P_picture) refers to a picture which may have references from another frame and can be used as a reference for other pictures. Compared to the I_picture, the P_picture may be coded with a greater efficiency.
Bi-directional picture (B_picture ) refers to a picture which may have references from two different frames, but it cannot be used as a reference picture. This kind of picture may be coded with the greatest efficiency.

Society of Motion Picture and Television Engineers (SMPTE) is a professional association for enhancing the profession and contributing to the technology of motion picture and television engineering. The SMPTE establishes standards, practices, and guidelines for the motion picture and television industry, including the audio that goes with the motion images. The SMPTE publishes the SMPTE Journal, a monthly. Membership is open to anyone who is interested.

How to use DVD Photo Slideshow to make photo DVD playable on TV?
