Abstract
The invention relates to a transcoder comprising a drift compensating loop (DCL) for compensating a drift signal (Ei) introduced in the transcoding path by a quantization operation (Q2). This drift compensation loop performs a motion compensation of a signal (F1) issuing from a previous dequantization (IQ1) resulting in a prediction signal (P1). The motion compensation is based on the drift signal stored in a memory unit (MEM). The drift signal and the prediction signal may be conveyed in an interlaced or de-interlaced structure. According to the invention, an AMC unit adapts the motion compensation operation with the de-interlaced or interlaced structures of the drift and prediction signals.
