We propose a frame rate up-conversion algorithm using the weighted-adaptive motion-compensated interpolation (WAMCI) that reduces the blocking artifacts due to block-based processing. The proposed method is based on the interpolation scheme by weighted sum of multiple interpolation filtering results. Also, the blocking artifacts on the block boundaries are reduced by applying a technique similar to the overlapping-block motion compensation (OBMC) in the proposed method. To reduce the drawback of overlapping processing, the proposed method uses the motion analysis to determine the type of motion and applies the WAMCI adaptively. Experimental results indicate good performance of the proposed scheme with significantly reduced blocking artifacts.

The paper presents symbol timing-offset compensation techniques to improve the reception performance of ATSC DTV receivers. Short and long echoes can induce timing-offset in the symbol timing recovery circuit. The timing-offset shifts sampling instants to the wrong points, causing the performance of the equalizer to become poor. When many echoes exist, the optimal sampling instant is the point at which the main-path has a peak value. By using channel estimation techniques, we find the optimal sampling instant, thereby compensating the timing offset and improving DTV reception performance.

We propose a new de-interlacing algorithm using two types of motion information, i.e., the block-based and the pixel-based motion information. In the proposed scheme, block-wise motion is first calculated using the frame differences. Then, it is refined by the pixel-based motion information. The results of hardware implementation show that the proposed scheme using block-wise motion is more robust to noise than the conventional schemes using pixel-wise motion. Also, the proposed spatial interpolation provides a good visual performance in the case of moving diagonal edges.

An embedded implementation of acoustic field enhancement is proposed, which is dedicated to stereo sound sources. With the use of the embedded DSP-base platform, this algorithm successfully constructs the signal processing filter structure to enhance a 3D acoustic field through either of stereo headphones and stereo speakers. The whole of proposed algorithm can be implemented by a 16 bit fixed-point DSP with the computational costs of 51.6 MIPS and 6.6 kB of memory, high-fidelity spatial acoustics can be achieved in various applications, such as portable stereo players, music streaming to mobile devices, etc.

Characterization of indoor antennas has become a current issue, especially with DTV. The GTEM (Gigahertz TEM) cell, originally made to test equipment for EMI susceptibility, is often available to CE designers. The device is also suited for measurement of relatively small indoor television antennas including those with integrated amplifiers.

This paper presents a one-pass VBR coding algorithm, which provides high visual quality and satisfies a target bit-budget constraint. Since the proposed algorithm exploits the remaining bit amount instead of average bit-rate in determining quantization scale, it can balance the target bit-budget. The proposed algorithm also achieves real-time VBR video encoding requiring high visual quality for storage media.
