摘要：A system and method for storing, retrieving displaying, printing and otherwisemanipulating color images stored in a central \"host\" computer from a realtor's remotedata terminal includes a host computer which stores and maintains a database containinglistings of real estate properties on the market. The host computer also optionally canstore image information relating to specific properties. Images can be loaded fromremote terminals over telephone lines to the host system on an interactive basis. Imagescan then be retrieved from the host system, also on an interactive basis, for display,printing, or storage on a storage medium associated with the remote display terminals.Images may also be deleted on an interactive basis from a remote terminal. A specificcommunications protocol conveys image data between the host computer and remotedata terminals. This protocol includes specific \"time- out\" limitations, CRC error checkingschemes, and a specific \"handshaking\" signalling sequence that must be observed beforethe host system will permit manipulation of image files.
