摘要:
An ocular lens material comprising a copolymer prepared by polymerizing a monomer mixture comprising, as main components, (A) 15 to 40% by mole of a fluoroalkyl (silicon-containing alkyl) fumarate, (B) 35 to 55% by mole of an N-vinyl lactam, (C) 3 to 30% by mole of at least one of acrylic acid and methacrylic acid, and (D) 0.1 to 20% by mole of a crosslinkable monomer. The ocular lens material is excellent in all of transparency, oxygen permeability, mechanical strength and hardness. Further, the material is excellent in hydrophilic property in spite of its low water absorption.

An ocular lens material comprising a copolymer prepared by polymerizing a monomer mixture comprising, as main components, (A) 15 to 40% by mole of a fluoroalkyl (silicon-containing alkyl) fumarate, (B) 10 to 50% by mole of a styrenic monomer, (C) 5 to 35% by mole of a hydrophilic monomer, and (D) 0.1 to 20% by mole of a crosslinkable monomer. The ocular lens material is excellent in all of transparency, oxygen permeability, mechanical strength and hardness. Further, the material is excellent in hydrophilic property in spite of its low water absorption.
摘要:
A water-absorptive soft contact lens material having a high transparency, an excellent flexibility, a high oxygen permeability independent of water content, a high mechanical strength and an adequate hardness, which comprises a copolymer prepared by the polymerization of a monomer mixture comprising an N,N-dialkyl acrylamide or methacrylamide, an N-vinyllactam and a bis(silicon-containing alkyl) fumarate in a specific ratio, and which provides water-absorptive soft contact lenses having excellent properties such as high transparency and high oxygen permeability.
摘要:
A water-absorptive soft contact lens comprising a polymer prepared by polymerizing a monomer mixture comprising, as main components, (A) 25 to 75% by weight of a (meth)acrylamide monomer, (B) 20 to 70% by weight of a fluoroalkyl (silicon-containing alkyl) fumarate, and (C) 0.01 to 10% by weight of a crosslinkable monomer. The water-absorptive soft contact lens has excellent oxygen permeability and high mechanical strength independent of water content, and is excellent in transparency and shape stability.

A content distribution system inhibits execution of processing which is unnecessary for streams having specific structures. The content distribution system includes a distribution server and a playback apparatus. The distribution server transmits a program stream and a program state flag associated with the program stream that indicates whether or not program content corresponding to the program stream is constituted of only 3D video. The playback apparatus determines, prior to decoding the program stream, whether or not the program state flag indicates that the program content is constituted of only 3D video, and when determining that the program content is constituted of only 3D video, decodes the program stream and performs control so as to play back the program stream as 3D video without determining whether or not each frame included in the program stream is a 3D video frame.

The present invention aims to provide a video processing device allowing notifications to be made to viewers of a program without annoyances being posed thereby. A video processing device comprises a receiver receiving video information including a subject program and flag information indicating whether the video information includes type-1 guide information for making a notification when the subject program is in 3D; a determiner determining, according to received flag information, whether the user is to be notified of the type-1 guide information; and an output controller outputting a program from the received video information, outputting type-2 guide information for making the notification when the subject program is in 3D and the determiner determines that the user is not to be notified of the type-1 guide information, and preventing output of the type-2 guide information when the determiner determines that the user is to be notified of the type-1 guide information.
摘要:
An encoding method is provided, according to which video streams obtained by compression-coding original images are contained in one transport stream. The video streams contained in the transport stream include a video stream that constitutes 2D video and video streams that constitute 3D video. When containing such video streams in the transport stream, a descriptor specifying the video streams constituting the 3D video is contained in a PMT (Programmable Map Table) of the transport stream.
摘要:
A content recommendation device and a content recommendation method that recommend appropriate content with appropriate timing are provided. The content recommendation device (300) is a content recommendation device (300) which recommends content to a user as recommended content, and which includes a recommended content determining unit (330) which determines second content as the recommended content, the second content being related to first content that is at least partially viewed by the user and a recommendation timing determining unit (350) which determines a recommendation timing for presenting information of the recommended content, based on a chronological relationship between the recommended content and third content which is related to the recommended content and is currently available or will be available for viewing.
摘要:
A content start control device that changes the resource to be started first within a content in accordance with the type of license purchased, and enables a plurality of viewing modes for one content is provided. The content start instruction reception unit 201 of the content start control device 100 receives a start instruction for a content, and sends the content ID of the content to the license information verification unit 211. The license information verification unit 211 obtains information on whether or not a license has been purchased, by using license information obtained from the license information storage unit 221 and the content ID obtained from the content start instruction reception unit 201. The start resource selection unit 212 selects the start resource of the content which is associated with the license, by using start resource information, and the resource starting unit 213 starts the resource selected by the start resource selection unit 212.
