Abstract: Combining with the application of Videophone in PSTN by using software and aiming at an important aspect, real-time videosequence capturing, in the realization of it, the key techniques in the realization of real-time video sequence captUring using the Video forWindows library provided by Visual C++ in Windows are discussed. The software realization diagram for real-time video sequence capturingis proposed and corresponding program examples are provided.
