Abstract
The subject of this thesis was the verification and the implementation of a multiple retransmission technique for the one-way asynchronous communication channel of the Interactive Video Data Service (IVDS) system. The commercial application of the IVDS project made reliability of the retransmission technique important. Verification of the reliability of the technique was done using a simulator written in the C programming language. The results of the IVDS simulator were compared to the existing statistical model of the transmission channel. Following a favorable comparison of the statistical model and simulator results, a prototype of the control section for the IVDS Consumer Control Unit (CCU) was designed and constructed. This was an important step towards the completion of the IVDS system. The CCU design defined protocols for message format and error detection and also helped to establish an IVDS test-bed system.
