“…That is, the deinterlacer banks give a new spatio-temporal scalable function, which we refer to as Field Scalability. In the article [8], as a primal application of the single stage motion-compensated deinterlacer banks, a simple two-layer field scalable video codec system using JPEG2000 was experimented. In the articles [10], [11], the multi-stage deinterlacer banks are developed for fine spatio-temporal multiresolution control.…”

In this paper, theoretical properties of deinterlacer banks are analyzed. Deinterlacer banks are novel filter banks in the sense that a progressive video sequence is separated into two progressive video sequences of a half frame rate and, furthermore, interlaced sequences are produced as intermediate data. Unlike the conventional filter banks, our deinterlacer banks are constructed in a way unique to multidimensional systems by using invertible deinterlacers, which the authors have proposed before. The system is a kind of shift-varying filter banks and it was impossible to derive the optimal bit-allocation control without any equivalent parallel filter banks. This paper derives an equivalent polyphase matrix representation of the whole system and its equivalent parallel structure, and then shows the optimal rate allocation for the deinterlacer banks. Some experimental results justify the effectiveness of the optimal rate allocation through our theoretical analysis.
