摘要： The present invention provides a transcoder having a MPEG decoder and a MPEG encoder, for changing a GOP structure and the bit rate of an encoded bitstream obtained as a result of an encoding process. The MPEG encoder receives a past encoding parameters generated at a past encoding process as a history information, and performs a present encoding process by using the past encoding parameters selectively so that the present encoding process is optimized. Furthermore, the encoder describe the past encoding parameters into the encoded bitstream as the history information so as to reuse the history information in advance encoding process. The picture quality of the video data does not deteriorate even if decoding and encoding processes are carried out repeatedly by the transcoder.

摘要： An apparatus and method to preferentially select code quantity from DPCM path in a manner to satisfy the target code quantity thereby preventing deterioration of image quality. Code quantities obtained by a first compression system of quantizing an input image signal by quantization steps different from each other, or code quantities obtained by a second compression system which has compression factor and loss which are lower than those of the first compression system are added on an encoding system selection basis to calculate a total code quantity of equi-length unit. A calculated total code quantity and a target code quantity in the equi-length unit are compared to determine quantization step in the first compression system in accordance with the comparison result to select, on the encoding system selection basis, the first compression system or the second compression system of performing quantization by the determined quantization step.

摘要： The present invention relates to a video signal processing apparatus and video signal processing method, a video signal encoding apparatus and video signal encoding method, and a program which can solve an EPB problem involved when an encoded video signal is subjected to smart rendering editing. In an extraction process, if EPB problem occurrence prevention countermeasures have been taken in an H.264/AVC stream, smart rendering editing is performed without monitoring the occurrence of an EPB problem. If the countermeasures have not been taken, smart rendering editing is advanced while monitoring the occurrence of an EPB problem. And, in a case where an EPB problem of insertion of an EPB has occurred, a filler or a predetermined parameter corresponding to the inserted EPB is deleted. In a case where an EPB problem of deletion of an EPB has occurred, a filler corresponding to the deleted EPB is inserted. The present invention can be applied to a device that processes a video signal using the H.264/AVC scheme.

摘要： An bit-plane coding pass generator is provided in which for SP-pass processing quantization coefficient of each code block divided into bit planes, “significant (S)” or “non-significant (N)” data in a predetermined area and those around the area and compared with an S/N matching pattern. The S/N matching pattern has been set when a jump can be made from an arbitrary sample point to a next sample point to be processed by SP pass. The jump is made to the next sample point to be processed by SP pass according to a jump address value obtained from a pattern coincident with a current S/N matching pattern. Thus, by reducing the time for the significant propagation (SP) pass defined in JPEG-2000, a code block can be coded at a higher speed by three coding passes.
摘要翻译： 提供了一种位平面编码遍发生器，其中针对每个代码块的SP-pass处理量化系数分为比特平面，在预定区域中的“有效（S）”或“非有效（N）”数据） 与S / N匹配模式进行比较。 当可以从任意采样点到下一个待通过SP处理的采样点进行跳变时，设置S / N匹配模式。 根据从与当前S / N匹配模式一致的图案获得的跳转地址值，对通过SP pass处理的下一个采样点进行跳转。 因此，通过缩短在JPEG-2000中定义的显着传播（SP）传递的时间，可以通过三次编码通过以更高的速度对代码块进行编码。

摘要： Two slide bases (106) synchronizingly traveled on linear guides (105) arranged upwardly and downwardly in parallel with each other are rotatably attached with a clincher unit (107) and a driver unit (104) and provided with a click stop mechanism for fixing the clincher unit (103) and the driver unit (104) at a 0 degree position or a 45 degree rotated position. Respective outer peripheral portion thereof are provided with claw portions (119), (120), in correspondence with the 0 degree position and the 45 degree rotated position and a stopper pin (121) is arranged at a traveling path. When the driver unit and the clincher unit are traveled from an initial position to a skewed binding position, the 0 degree claw portion 119 impinges on the stopper pin (121) and the driver unit and the clincher unit are rotated to the 45 degree rotated position to fix. When the driver unit and the clincher unit are traveled reversely to the initial position, the 45 degree claw portion (120) impinges on the stopper pin (121) and the driver unit and the clincher unit are returned to the 0 degree position to fix.
