Title: A modified video coding algorithm based on the H.261 standard
Abstract: The development of multimedia systems, which can handle voice and video, is fast growing. Image and video capacity are the essential components of a multimedia system. Representing digital video requires large amount of data, thus, video compression is necessary. In this research composition, the H.261 video compression standard is examined and a video compression algorithm based on the said standard is implemented. Application of H.261 compression algorithms are done with efficiency in mind to provide the least compromise between the computational speed and compression ratio. To make such implementation practicable, the heart of its compression algorithm - the discrete cosine transform, quantization, and variable length coding, are analyzed carefully and fast implementations that do not considerably reduce image quality are incorporated in the codec.
