This paper presents an overview of the latest transform and quantization designs for H.26L. Unlike the popular discrete cosine transform (DCT) used in previous standards, the transforms in H.26L can be computed exactly in integer arithmetic, thus avoiding inverse transform mismatch problems. The new transforms can also be computed without multiplications, just additions and shifts, in 16-bit arithmetic, thus minimizing computational complexity, especially for low-end processors. By using short… CONTINUE READING
