Abstract

The main goal of transcoding is to change bit rate of video sequence. This can be done by cascaded connection of decoder and encoder, known as Cascaded Pixel Domain Transcoder (CPDT). Decoding and re-encoding video bit stream always gives lower image quality than encoding original sequence. This paper presents a new technique of video transcoding that is able to deliver image quality superior to CPDT and has lower computational complexity. The technique is restricted to homogeneous (within the same bit stream format) transcoding of bit streams encoded according to H.264/AVC(MPEG 4) standard specification. The standard defines different types of encoded frames but proposed technique is designed for I(ntra) type frames only.
