Video over Cellular Mobile Device based on Hybrid Technique

Video compression is considered of high importance especially for mobile devices such as laptops and cellular devices. Thus the need for adapting video signal over these device arises mainly to save bandwidth and reduce time. In this paper a new method is proposed of adapting video signal over cellular mobile devices by combining an adaptive method and a compression method (JPEG). JPEG is a standardized image compression mechanism, but in this paper used a different huffman coding for our compression method instead. The compression algorithm is modified to incorporate compression 24 color image as well as 8 bit gray scale image. DCT is used for transform coding. Run-length and Huffman coding are used for achieving compression. Using this approach the 24 bit color image is compressed.
