The paper presents a novel and fast transcoding scheme with PIP (Picture-in-Picture) functionality based on H.264/AVC standard. We seamlessly achieve significant speedup and maintain identical video quality for the composite video content using two H.264 bitstreams. The proposed Partial Re-Encoding transcoder (PRET) method based on the intra-prediction(More)
This paper presents a unified systolic architecture for inter and intra predictions in H.264/AVC decoder. To increase hardware utilization and minimize cost, we combine inter and intra predictions by a reprogrammable FIR filter, which is further implemented using systolic array. For intra prediction, the boundary pixels are reshuffled before feeding into(More)
Recommended by Alex Kot This paper proposes a low-complexity multiple-window video embedding transcoder (MW-VET) based on H.264/AVC standard for various applications that require video embedding services including picture-in-picture (PIP), multichannel mosaic, screen-split, pay-per-view, channel browsing, commercials and logo insertion, and other visual(More)
