Abstract:
1. A device for determining a sequence of values for an encoding parameter of a hybrid encoding scheme, which includes for each frame of a frame sequence of N frames, a value which is selected from of a predetermined set of M predetermined values for the encoding parameter, for use for encoding the frame sequence by using the hybrid encoding scheme, the device comprising: a data establisher configured to establish, using the hybrid encoding scheme, distortions and compression rates for the frames of the frame sequence, by: a data estimator configured to, for a predetermined frame of the frame sequence, establish, per fragment sequence which includes, for each frame from the first frame to the predetermined frame of the frame sequence, exclusively, the same values as a predetermined one of the supporting sequences, respectively, but differ from the predetermined supporting sequence in a value of the encoding parameter for the respective one of the frames, estimated distortions and compression rates for frames of the frame sequence which follow the predetermined frame, under association of a respective fragment sequence to the one of the supporting sequences for which a determined distortion of the predetermined frame includes a smallest difference to the distortion established using the respective fragment sequence; and a first determiner configured to determine the sequence of values for the encoding parameter of the hybrid encoding scheme, based on the distortions and compression rates as determined from the encodings performed by the data establisher, and the estimated distortions and compression rates as established by the data estimator; wherein at least one of the data establisher, the data estimator and the first determiner comprises a hardware implementation.
