Abstract
Abstract An apparatus for selecting areas of a film which are of no interest to a user, coding these unimportant areas for identification purposes and selecting the important areas to be translated into useable information. The important information and a code for the unimportant information is transmitted to a user facility, thereby decreasing the information transmitted to the user and conserving the bandwidth required for transmission.
