Abstract: The video signal is an integral part of multimedia which has a tremendous importance in most of the applications involving the concept of the multimedia i.e. video conferencing; video-on-demand, broadcast digital video, and high-definition television (HDTV), etc. which are expected to have a substantial end user or the consumer market. It means that these applications which are based on the basic principle of the digital signals having both component of the audio and video, are using the most dominant approach of the video compression techniques so as to make the best and efficient use of the available bandwidth. The existing video coding techniques such as those used in MPEG-1 (ISO), MPEG-2 (ISO), MPEG-3 (ISO), H.261 (ITU), and H.263 (ITU) are the typical and most commonly used standards that employ the basic and most essential schemes or techniques that uses the intra frame coding or inter frame coding techniques so as to achieve the high desired compression rates. In this discussion, the authors put forward an innovative approach of the video signal compression that makes the use of the advanced H.264 algorithms which are based on the application of DCT & wavelet based video compression of the multimedia based signal. The simulation of the considered image has been carried out with a comparative analysis of the results that has been obtained with the traditional approach as well as proposed one i.e. SPIHT (Set Partitioning in Hierarchical Trees) algorithm for video compression of the signal.
