Holograms are being produced using optical methods for decades. A lot of techniques and methods exist for the production of efficient holograms. Digital Holography (DH) is the method of simulating holograms with the use of computer. In this paper digital holograms are generated using Fresnel and Fraunhofer diffraction integrals. Multi color holograms are simulated and the digitally generated holograms are analysed. DH technique is extended further to video format which yields video holograms. The concept that every bit of a hologram contains full information of the original video, which is being effectively utilized to reduce the file size required for communication in terms of storage, security and speed. The entire process is simulated using Matlab7.10 environment.
