You can imagine, streaming 25 HD images per second requires an immense amount of disk space both on the server and user sides. For example, 60 seconds of video requires about 1Gb of memory space. Fortunately, there are several ways to compress this data. The first approach is to install special compression programs both on the user and server sides. These programs compress video on the server-side, transmits the file to the user, uncompressed it, and send it to the screen/speakers. The drawback of this approach is to pre-install the program on the user’s side.
