The analysis and design of windowed Fourier frame based multiple description source coding schemes

In this paper the windowed Fourier encoding–decoding scheme applied to the multiple description compression problem is analyzed. In the general case, four window functions are needed to define the encoder and decoder, although this number can be reduced to three or two by using time-shift or frequency-shift division schemes. The encoding coefficients are next divided into two groups according t...

the analysis of the role of the speech acts theory in translating and dubbing hollywood films

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...

Multiple Description Coding Schemes for the H.264/AVC Coder

The recent development of multimedia communications across unreliable channels has brought the need for robust coding techniques, such that a partial loss of information does not necessarily imply the loss of the whole video sequence. The implementation of Multiple Description Coding (MDC) schemes based on the H.264/AVC coding standard provides an affordable solution to this problem. This paper...
