We propose a new algorithm to reject the rustle noise in a pen-type voice recorder. In the proposed method, we estimate the subspace on each subband, and design the optimal filter.

A phase-locked loop is commonly used for carrier synchronization in a communication receiver. A carrier synchronizer with an adaptive loop bandwidth for rapid carrier frequency offset acquisition and low steady-state jitter is proposed. The new carrier recovery loop consists of a tracking-status detector and a loop bandwidth controller. The tracking-status detector monitors the frequency-estimate signal output from the loop filter, determining whether the residual carrier frequency offset is locked or not. Then, by adjusting the loop bandwidth, it can reduce the convergence time of the acquisition-state and carrier jitter of the steady state. The new scheme, implemented by FPGAs, has been successfully applied to a 256-QAM baseband digital receiver and inter-operated with commercial CMTSs. Only around 11200 gates are needed for the new carrier synchronizer; however, the SNR can be improved by up to 3 dB.

This paper describes the proposed improvements to the ATSC DTV standard. The proposal provides a mechanism for embedding a new robust bit-stream in the standard bitstream in a backward compatible manner. The robust stream has a higher threshold of visibility (TOV) compared to the standard stream and can be transmitted either in the pseudo 2-VSB mode or in the E-VSB mode. A prototype transceiver system, based on the proposed system, has been developed and is being tested in the field.

The paper presents motion adaptive search (MAS), that effectively utilizes motion activity information to achieve superior performance both in terms of quality and speed in comparison with other fast search algorithms for motion estimation. The main features of MAS are: the early elimination of search by detecting the stationary macroblocks; the adaptation of both the search window size and the search strategy based on motion activity information; the minimization of overlap of search points by performing intelligent search.

We propose a motion vector correction algorithm to correct the erroneous motion vectors due to the failures of conventional motion estimation (ME) based on block matching algorithms (BMA). The proposed method is based on the pattern-like image analysis that corrects the erroneous motion vectors by considering multiple possible motion vectors and by excluding the wrong motion vectors. Also, it does not significantly increase computational complexity since it uses the estimated motion vectors and the sum of absolute difference (SAD) previously obtained from the conventional ME. Experimental results indicate good performance of the proposed scheme combined with frame rate up-conversion system.

As a simple and intuitive interface, a new-style mobile terminal without a single operation button has been developed. The terminal contains an accelerometer and is operated by gestures, such as changing its inclination or by shaking it, replacing conventional button operation. The list of contents is presented as "bubbles flowing in the water" instead of the conventional hierarchical structure. Using such gesture commands allows the user to enjoyably browse contents such as text, video, still pictures, and music.

In this paper, we have proposed the merging of the OpenCable reference model with the smart card interface defined by ISO/IEC 7816-3 and have implemented a new conditional access system (CAS) using this interface along with a Personal Computer Memory Card International Association (PCMCIA) interface. In addition, we have also designed the hardware architecture of the point-of-deployment (POD) security module, designed with the Verilog HDL, using the above two interfaces. The designed POD security module has an embedded 32-bit reduced instruction set computer (RISC) microprocessor that manages applications, such as an MPEG-2 filter, descrambler, and Data Encryption Standard (DES).

The paper proposes an ROI (region of interest) video coding algorithm based on H.263+. The ROIs are automatically selected by a robust skin-color detection which utilizes the Cr and RGB variance instead of the traditional skin color models, such as YCbCr, HSI, etc. The skin color model defined by Cr and RGB variance can choose the skin color region more accurately than other methods. For the video coding system, a region-based video codec based on H.263+ with the option mode of modified quantization is set up. We adjust the distortion weight parameter and variance at the macroblock layer to control the qualities at different regions. Experimental results show that the proposed method can significantly improve the quality at the ROI. Our method is suitable for real time videoconferencing.
