Abstract: The increasing demand to incorporate video into communications services and the continuous developments in telecommunication, create a demand for finding efficient ways for compression techniques. In this research, the interframe approach is designed and implemented by Visual Basic language 6.0 with H.263, where the H.263 is the most important compression standard for video over the Internet. Many techniques have been applied for motion estimation for video compression. The motion estimation process is the most significant factor in a video compression process.

Abstract: Telephone networks are an essential part of modern life, the newest version or generation is the broadband integrated services digital network (BISDN). The B-ISDN uses the ATM as a transmission protocol. ATM is a streamlined form of packet switching suitable for high speed networks; it developed as a part of B-ISDN. Its importance grows especially after the introduction of IP over ATM. It is a flexible mode of transfer. It can provide many QoS categories and can work with different rates.
