Patent ID: 8462845

Claim:
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: completely encoding the frame sequence with different supporting sequences of values for the encoding parameter, out of M N possible sequences of values, and determining a distortion and a compression rate of the completely encoding per frame for each supporting sequence, encoding, for respective frames of the frame sequence from a second frame of the frame sequence up to the N th frame of the frame sequence, the frame sequence from a first frame of the frame sequence to one of the respective frames of the frame sequence with, for each supporting sequence, fragment sequences of values for the encoding parameter, which include, for each frame from the first frame to the one of the respective frames of the frame sequence, exclusively, the same values as a respective supporting sequence, respectively, but differ from the respective supporting sequence in a value of the encoding parameter for the one of the respective frames, and determining, for each fragment sequence, a distortion and a compression rate of the encoding per frame from the first frame of the frame sequence to the respective frame of the frame sequence; 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.
