    • A glucan derivative (e.g., a cellulose acylate derivative) which is useful for a thermoplastic resin, is inhibited in hygroscopicity at a high level and is excellent in compatibility with a plasticizer or solubility in a solvent is provided. In the glucan derivative which comprises an acyl group and a graft chain formed from at least one graft component selected from a lactone and a hydroxycarboxylic acid, each bonding to a glucose unit of a glucan (e.g., a cellulose) constituting the glucan derivative, a hydroxyl group in the graft chain is protected with a protecting group. The graft chain may be formed from a C4-16lactone. The hydroxyl group in the graft chain may be protected with an acyl group (e.g., a C2-8alkylcarbonyl group such as acetyl group). The degree of substitution of the acyl group may be from 1 to 2.99, and the degree of substitution of the graft chain may be from 0.01 to 2.

    • Disclosed is a method for producing a cyclic ester-modified glucan derivative wherein generation of homopolymers of the cyclic ester can be highly suppressed. Specifically disclosed is a method for producing a modified glucan derivative to which a cyclic ester is graft-polymerized, wherein a glucan derivative having a hydroxyl group and a cyclic ester are reacted in a solvent in the presence of a ring-opening polymerization catalyst. In this method, (1) the ring-opening polymerization catalyst is composed of a metal complex which does not initiate polymerization of the cyclic ester by itself; (2) the solvent is composed of an aromatic hydrocarbon solvent having a solubility in water at 20° C. of not more than 10% by weight; and (3) the ratio of the solvent is set at not less than 60 parts by weight per 100 parts by weight of the glucan derivative having a hydroxyl group.

    • For a plurality of digital video signals whose frame frequencies are different, a pixel number converting circuit to convert the number of pixels is provided so that differences of the frame frequencies are replaced to differences of the numbers of pixels and a plurality of digital video signals whose frame frequencies are different can be processed by a common clock frequency. The frame frequency is detected by a frame frequency value decoder and the number of pixels in the horizontal direction of the pixel number converting circuit is properly set in accordance with the frame frequency. As mentioned above, if the differences of the frame frequencies are replaced to the differences of the numbers of pixels and the images are converted into the image in which the frame frequencies are the same and the numbers of pixels are different, the frame frequencies are equalized and the signals can be processed by the same clock.
    • 对于帧频不同的多个数字视频信号,提供转换像素数目的像素数转换电路,使得帧频的差异被替换为像素数量和多个数字视频信号的差异 帧频不同可以通过公共时钟频率进行处理。 帧频由帧频值解码器检测,并且像素数转换电路的水平方向的像素数根据帧频适当地设定。 如上所述,如果将帧频的差异替换为像素数的差异,并且将图像转换为帧频相同且像素数不同的图像,则将帧频均衡 信号可以通过相同的时钟进行处理。

    • When a digital broadcast receiver selects a channel and thereby changes an MPEG picture stream, a video decoder starts a decoding operation in response to an instruction to start decoding. When a predictive coded picture includes an intra slice and an intra macroblock, the video decoder decodes the intra slice and the intra macroblock of the predictive coded picture without waiting for an intra picture to be decoded. When a macroblock to be referred to has previously been decoded, the video decoder further decodes a non-intra slice and a non-intra macroblock of the predictive coded picture by using a decoding result of the macroblock to be referred to. Thus, when changing the channel, for example, it is possible to quickly obtain output picture data, shorten interruption of the pictures, and check a picture of the next channel in a short time.
    • 当数字广播接收机选择信道并从而改变MPEG图像流时,视频解码器响应于开始解码的指令开始解码操作。 当预测编码图像包括帧内和帧内宏块时,视频解码器解码预测编码图像的帧内和帧内宏块,而不必等待帧内图像被解码。 当要参考的宏块先前被解码时,视频解码器通过使用要参考的宏块的解码结果进一步解码预测编码图像的非帧内和非帧内宏块。 因此,当改变频道时,例如,可以快速获得输出图像数据,缩短图像的中断,并在短时间内检查下一个频道的图像。
