A Fast PU Mode Decision Algorithm for H.264/AVC to HEVC Transcoding
Open accessAbstract
H.264/AVC has been widely applied to various applications.However, a new video compression standard, High Efficient Video Coding (HEVC), had been finalized recently.In this work, a fast transcoder from H.264/AVC to HEVC is proposed.The proposed algorithm includes the fast prediction unit (PU) decision and the fast motion estimation.With the strong relation between H.264/AVC and HEVC, the motion vectors (MVs), residuals, and modes from each coding block of H.264/AVC can be reused to predict the current encoding PU of HEVC.Furthermore, the MV variance from H.264/AVC is calculated to decide the search range of PU and also to reduce the prediction mode.Simulation results show that the proposed method can save up to 53% of the encoding time and maintains the rate-distortion (R-D) performance for HEVC.

The proposed scheme is suitable for both H.264/AVC and HEVC video codec standards.
“As mentioned in Section 1, the scheme is suitable for both current video codec standards, the H.264/AVC standard [20] and the HEVC codec [21]”
From Effectiveness of crypto-transcoding for H.264/AVC and HEVC video bit-streams (2019) · cites this paper as [21]
The Introduction (p. 1) describes a transcoder that takes H.264/AVC input and reuses its parameters to encode HEVC output, so the paper supports a method involving both standards. It does not establish that the citing document’s proposed scheme is suitable for both codecs generally. (LLM, conf=0.82)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
