Visual Psychology
There are two type of visual psychologies, high number of sequencial image frames per second in streaming video and visual range of radio frequencies. Optimum numbers of image frames at least 25 frames per second is acceptable for video streaming. These sampled image frames are processed for transmission and storing. For better compression, sequencial frames are differentiated and only difference signal can be processed.
This optimum sampling of video streaming reduces the data rate per second for transmission of video stream.
Coding
Image frames can be coded with lower number of data bits per pixel. Sequencially differentiated image frames can be coded with lower difference with lower number of data bits per pixel and higher difference with higher data bits assuming lower difference with low information content and higher difference with higher information content.
Further coded data bits could be compressed using discrete wavelet transform, where wavelet function is chosen in such a way higher number of transformation coefficients equals to zero or tends to zero. Thus better compression can be achieved.
