An adapt flexible macroblock ordering strategy based on unequal protection scheme is presented for video transcoding. The key point of our scheme is selecting the important macroblocks which belong to a separate slice group under prior protection in transmission. The judgement of the importance of the macroblocks is based on the differences of the DCT coefficients of neighbouring subblocks in a macroblock...
This paper presents some key issues in fiber-optic interferometric magnetic field sensors. Practically applicable methods to design and implement fiber-optic Michelson interferometer and transducers are described with experimental verifications. Detection scheme of traditional hardware demodulation is improved, and a new software demodulation method is addressed. Transducers were implemented by using...
