Title: ENCODER AND CONCEPT FOR CONFIGURING SAME
Abstract:
A more effective configuration of an encoder for encoding a media signal in units of segments by encoding each segment by executing at least one of a set of encoder operations may be rendered more effectively is achieved by having the encoder segmentally traversing at least a conditional subset of the set of encoder operations and making, for each operation of the conditional subset, a decision on executing the respective encoder operation on the basis of a decision function. If the decision function indicates that the respective encoder operation is to be executed, the encoder executes the respective encoder operation so as to obtain a set of features and the arguments of the decision function on the basis of which the decision on executing the respective encoder operation is made comprises the sets of features obtained by the execution of preceding encoder operations. Then, the encoder determines which of an executed subset of the set of encoder operations results in a coded representation of the respective segment which is extremal in terms of a predetermined optimization criterion. The coded representation of the encoder operation thus determined is used for encoding the respective segment. The encoder thus prepared enables to be configured in a manner which trades off maximizing the predetermined maximization criterion on the one hand and some other criterion on the other hand, namely computational effort. Configuration of such encoder(s) is also described.
