One key problem in video compression is the operational control of the source encoder. This problem is compounded because typical video sequences contain widely varying content and motion, necessitating the selection between different coding options with varying rate-distortion efficiency for different parts of the image. The task of coder control is to determine a set of coding parameters, and thereby the bit-stream, such that a certain rate-distortion trade-off is achieved for a given decoder. This chapter focuses on coder control algorithms for the case of error-free transmission of the bit-stream. A particular emphasis is on Lagrangian bit-allocation techniques, which have emerged as a widely accepted approach. The popularity of this approach is due to its effectiveness and simplicity.
