In accordance with an embodiment, a method of decoding an encoded audio bitstream at a decoder includes receiving the audio bitstream, decoding a low band bitstream of the audio bitstream to get low band coefficients in a frequency domain, and copying a plurality of the low band coefficients to a high frequency band location to generate high band coefficients. The method further includes processing the high band coefficients to form processed high band coefficients. Processing includes modifying an energy envelope of the high band coefficients by multiplying modification gains to flatten or smooth the high band coefficients, and applying a received spectral envelope decoded from the received audio bitstream to the high band coefficients. The low band coefficients and the processed high band coefficients are then inverse-transformed to the time domain to obtain a time domain output signal.

Video encoding

The invention relates to a video encoder (201) for encoding a video signal. The video encoder comprises a segmentation processor (207) which divides the picture into picture regions. Preferably, picture regions having a high degree of flatness or uniformity are determined in this way. A characteristics processor (209) determine a spatial frequency characteristic for each picture region, and a coding controller (211) selects an encoding block size, such as a prediction block size for motion estimation, in response to the spatial frequency characteristic. An encode processor (213) encodes the picture using the selected encoding block size. Specifically, increasing block sizes are selected for increasing degrees of uniformity or flatness indicated by the spatial frequency characteristic. Thereby, an increasing proportion of high frequency components and a consistent choice of encoding block sizes are maintained, and thus the coding artefacts from many encoders having variable prediction block sizes is reduced. The invention is particularly suitable for H.264 and similar encoders.

Semiconductor substrate and its production method, semiconductor device comprising the same and its production method

When a SOI substrate is produced a first silicon layer epitaxially grown on the insulating underlay is ion implanted to make deep part of interface of the silicon layer amorphous, and then annealed to recrystallize. Next, the silicon layer is heat treated to oxidize part of the surface side, and after the silicon oxide is removed by etching, a silicon layer is epitaxially grown on the remaining first silicon layer to form a second silicon layer. Subsequently, the second silicon layer is again ion implanted to make deep part of interface amorphous, then annealing is performed to recrystallize. With this method, a SOI substrate, which is very small in crystal defect density of the silicon layer and good in surface flatness, can be produced. Therefore, on the semiconductor substrate an electronic device or optical device having high device performance and reliability can be realized.
