METHOD AND DIGITAL VIDEO ENCODER SYSTEM FOR ENCODING DIGITAL VIDEO DATA
First Claim
1. A method for encoding digital video data corresponding to a sequence of original input video frames, comprising:
- encoding a first original input video frame into an INTER-frame,decoding and reconstructing the INTER-frame into a reference frame,creating an INTRA input frame comprising information from both a second original input video frame and the reference frame, andencoding the INTRA input frame into an INTRA-frame.

Abstract
A method is used for encoding digital video data corresponding to a sequence of original input video frames. The method comprises: encoding a first original input video frame into an INTER-frame; decoding and reconstructing said INTER-frame into a reference frame; creating an INTRA input frame comprising information from both a second original input video frame and said reference frame; and encoding said INTRA input frame into an INTRA-frame. A digital video encoder system is used for encoding digital video data corresponding to a sequence of original input video frames by encoding the sequence of original input video frames using INTRA- and INTER-mode.

11. A digital video encoder system for encoding digital video data corresponding to a sequence of original input video frames by encoding the sequence of original input video frames using INTRA- and INTER-mode, comprising:
-
an encoder module being arranged to process input frames into an INTRA-frame or an INTER-frame; a decoder module being arranged to decode the INTRA- or the INTER-frame encoded by the encoder; a motion compensation module being arranged to use the information from the decoder module in order to reconstruct the encoded frame into a reference frame; and an INTRA input frame construction module being arranged to create an INTRA input frame using information from an original input video frame as well as information from a previously encoded and reconstructed reference frame, wherein the encoder module when encoding an INTRA-frame is arranged to use the INTRA input frame being constructed by means of the INTRA input frame construction module; wherein the INTRA input frame construction module is arranged to use information from a reference frame being formed by encoding a first original input video frame into an INTER-frame and thereafter reconstructing the INTER-frame into the reference frame and information from a second original input frame to create the INTRA input frame. - View Dependent Claims (12, 13)
