摘要： Herein disclosed is an apparatus for transcoding a coded multiplexed sound and moving picture sequence comprises the rate converter, which is operated to compress only the video bit streams, which have extremely large information volume. The compression operation is carried out through the steps of (a) operating the MPEG-2 TS demultiplexer to demultiplex the input MPEG-2 transport streams into video TS, audio TS, and system information TS; (b) operating the MPEG-2 video transcoder to transcode the video TS to generate output video TS having information volume less than the video TS; (c) operating the system controller to modify or not modify part of fixed codes of the system information TS in accordance with the output MPEG-2 transport streams; (d) operating the MPEG-2 TS multiplexer to multiplex the video TS thus transcoded, the audio TS, and the eventually partly-modified or not modified system information TS into output MPEG-2 transport streams, and output the output MPEG-2 transport streams, thereby making it possible to control the output bit rate less than the input bit rate.

摘要： Herein disclosed is a multiple-output bit stream separating apparatus for inputting an original MPEG-2 bit stream to separate into a plurality of transcoded MPEG-2 bit streams and a plurality of differential bit streams, and a multiple-output bit stream merging apparatus for inputting the transcoded MPEG-2 bit stream and the differential bit streams to reconstruct the original MPEG-2 bit stream. The bit rate of the transcoded MPEG-2 bit stream and the differential bit streams thus multiple times separated are much lower than that of the original MPEG-2 bit stream. This leads to the fact that the multiple-output bit stream separating apparatus and the multiple-input bit stream merging apparatus can promptly and reliably transmit and receive an original MPEG-2 bit stream having a large bit rate by transmitting and receiving a plurality of transcoded MPEG-2 bit streams and a plurality of differential bit streams in place of the original MPEG-2 bit stream.

摘要： Herein disclosed a bit stream separating apparatus for inputting and transcoding an original MPEG-2 bit stream, and separating the transcoded MPEG-2 bit stream to generate a transcoded MPEG-2 bit stream and a differential bit stream, which is a differential bit stream between the original MPEG-2 bit stream and the transcoded MPEG-2 bit stream, and a bit stream merging apparatus for inputting and merging the transcoded MPEG-2 bit stream and the differential bit stream to reconstruct the original MPEG-2 bit stream. The bit stream separating apparatus makes it possible for the bit stream merging apparatus to reconstruct the original, high quality, MPEG-2 bit stream from the transcoded MPEG-2 bit stream already received and the differential bit stream, thereby eliminating the effort and time to send the original MPEG-2 bit stream again.

摘要： An optical access network method, an optical access network and an optical switch for an optical access network, capable of solving all the three problems in the conventional GE-PON: transmission distance problem, security problem and communication interference problem. The optical access network comprises an OLT, a plurality of ONUs and one or more stages of optical switches, which are connected one another. In the direction from the OLT to the ONU, each frame (packet) transmitted from the OLT to one of the ONUs is checked so that only the destination ONU specified in the frame (packet) is connected to the OLT. In the direction from the ONU to the OLT, a control message transmitted from the OLT to one of the ONUs is checked so that only one ONU which has been given a transmission allowance from the OLT is connected to the OLT with respect to each frame (packet).

摘要： In a computer system comprising first through K-th arithmetic processors connected to a control section (18) in an ascending order, where K represents a positive integer which is not less than two, a memorizing unit (20) memorizes first and second information. A clock controlling unit (21) detects a fault signal produced by a k-th arithmetic processor, where k represents one of 1 through K. When the memorizing unit memorizes the first information, the controlling unit controls a supplying unit (19) to put the k-th through the K-th arithmetic processors out of operation. When the memorizing unit memorizes the second information, the controlling unit controls the supplying unit to put the first through the K-th arithmetic processors out of operation even upon production of the fault signal by any one of the first through the K-th arithmetic processors. Besides a first group of the first through the K-th arithmetic processors, a second group may be included in the computer system to comprise an additional arithmetic processor connected to the control section. When the memorizing unit memorizes the first information, the additional arithmetic processor is kept in operation. When the memorizing unit memorizes the second information, the additional arithmetic processor is put out of operation.

摘要： In distribution of high definition video signals in which it is possible to freely move viewing regions, systems and methods allow for determining viewing movement without dependence on user operation. In at least one embodiment, a video region of an input video signal is divided into a specified number of regions, and generates a plurality of video signals corresponding to each of the divided regions. The plurality of video signals are encoded to generate a plurality of video bit streams that are stored in a video bit stream group storage section. A video bit stream is extracted from the storage section based on the viewpoint movement information, and a transmission video bit stream is transmitted to a receiving unit. Viewpoint movement information is determined in order to specify a region for viewing from among the video regions. The viewpoint information is determined regardless of user instruction, based on specified data.
