摘要： An optical block which is light in weight and low in price, and has optical path distances equivalent to those obtained with glass has an outside form composed by arranging a polyhedron 8a having a surface of incidence for a blue ray B, a polyhedron 8b having a surface of incidence for a red ray R and a polyhedron 8c having a surface of incidence for a green ray G which are configured as transparent plastic members, and optical members 9a and 9b configured as dichroic filters formed as glass members. The polyhedrons 8a to 8c are coupled by way of the optical members 9a and 9b so as to compose an optical block as a monochromator prism block.

摘要： An interconnection between fully synchronous networks of the prior art and next generation frame communications networks, which is required for the shift to next-generation packet networks and a broader-based connection service, is realized. Here, the first point is that a means of bidirectional frame format conversion between a synchronous multiplexing system and a logical multiplexing system is provided, and a method of transmitting data between different networks on a path as if it was being transmitted in the same network. The second point is that when converting network control information in an STM network into data suitable for a packet network, even across the boundary of a synchronous multiplexing system and a logical multiplexing system, a unified communication management means is provided over the whole path. For this purpose, a hierarchized logical path control method is used wherein, in a network comprising two or more information relay devices having one or more line interfaces, this network performs communication between information relay devices using data packets, and has a means, when performing communication between any two points in the network, to control the path via which the packets pass between arbitrary end points, and the communication control means has a first communication path management function which performs communication management at the connection level which is terminated at the end point of a communication section, and a second communication path management function which performs communication management for each section of a physical circuit or logical circuit which is terminated at each communication section between any adjacent information relay devices in the communication section.

摘要： [Object] To prevent image quality deterioration due to unnecessary format conversion.[Solution] An STB (set top box) 200 receives bit stream data that is transmitted from a broadcast station 100 in such a manner as to be carried on a broadcast wave, and obtains stereoscopic image data, audio data, and the like. Furthermore, the STB 200 transmits the stereoscopic image data and the audio data to the TV (television receiver) 300 through the digital interface of HDMI. In a case where the received stereoscopic image data can be handled by a TV 300 and, furthermore, the TV 300 has requested that transmission of the stereoscopic image data be performed without performing format conversion, the STB 200 does not convert the format of the received image data, and transmits the received image data to the TV 300 in the as-is format. Furthermore, in the case of other cases, the STB 200 converts in advance the format of the received stereoscopic image data into, for example, a format that is set by the user, and transmits the stereoscopic image data to the TV 300.
