Abstract

The effective usage of transmission resources is becoming very important problem as new coding systems are extremely efficient and data transmission channels have higher throughput. That force us to look at the rate control algorithms. This paper presents test results of using local bitrate estimation instead of basic rate control algorithms for video sequences with intra-frame prediction. Local bitrate estimation enables inter and extrapolation of rho-rate function in neighborhood of currently used QP. This approach simplifies rate control process by excluding complex error-based operations.
