摘要:
A content purchase processing terminal achieves smooth purchase processing of content without the need for burdensome interactions between a content distributor and a user who wants to purchase the content. A content purchase processing terminal includes a secret information managing section for managing secret information on the user and the terminal, an authentication processing section for authenticating whether metadata selected by the user has been issued by the distributor, and a purchase processing section for requesting the purchase processing of the content by means of the secret information from the secret information managing section when the metadata is successfully authenticated.
摘要:
A measurement system (222) for measuring the position of a stage (248) along a first axis includes a first system (260) having a first beam source (260A) that directs a first beam (260H) on a first path that is parallel with a second axis and a first redirector (260D) that redirects the first beam so that the redirected first beam (260H) is on a first redirected path that is parallel with the first axis irrespective to the orientation of the first redirector (260D) about a third axis. The measurement system (222) can include a shield (380) that protects the first beam (260H) from environmental conditions.

摘要:
A graft copolymer produced by polymerizing 2-hydroxyethyl methacrylate, or monomer mixture containing the monomer, by using initiator produced by copolymerizing (A) N-vinyllactam or styrene and (B) peroxy-fumarate or combination of the peroxy-fumarate and diester of fumaric acid, the peroxy-fumarate being represented by the formula (I): ##STR1## wherein R1 is a linear alkyl, branched alkyl or cycloalkyl group containing not more than 18 carbon atoms, or an aromatic hydrocarbon group containing 6 to carbon atoms; and R2 is a linear alkyl, branched alkyl or cycloalkyl group containing not more than 13 carbon atoms, or a phenyl group.A solution for treating a contact lens, including the above graft copolymer and a solvent dissolving the copolymer. A method of treating a contact lens, comprising the step of wetting a surface of the contact lens with the above solution, and the step of contacting the wetted surface with a poor solvent, thereby modifying the hydrophobic contact lens surface into a hydrophilic surface.
摘要:
A polymer-type polymerization initiator produced by copolymerizing (A) 40 to 60 mole % of an N-vinyllactam and (B) 60 to 40 mole % of at least one fumarate containing a peroxy group, the peroxy-fumarate (B) being represented by the following formula: ##STR1## wherein R1 is a linear alkyl, branched alkyl or cycloalkyl group containing not more than 18 carbon atoms, or an aromatic hydrocarbon group containing 6 to 18 carbon atoms; and R2 is a linear alkyl, branched alkyl or cycloalkyl group containing not more than 13 carbon atoms, or a phenyl group.The peroxy-fumarate (b1) may be used in combination with (b2) at least one diester of fumaric acid selected from the group consisting of alkyl fluoroalkyl fumarate, alkyl silicon-containing-alkyl fumarate, fluoroalkyl silicon-containing-alkyl fumarate, bis(fluoroalkyl) fumarate, and bis(silicon-containing-alkyl) fumarate, a mole ratio of the peroxy-fumarate to the diester of fumaric acid falling within a range of 9 to 1 to 1 to 9.
摘要:
To provide a content distribution system which 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.
摘要:
An electronic notification device (100) is provided which is capable of presenting, to a user, content which the user wishes to view, from a large number of pieces of content without the need for a large number of user operations. An electronic notification device (100) notifies a user whether content is available via a network, and includes a content availability checking unit (110) which obtains content availability information indicating one or more pieces of content available via the network; a specifying unit (120) which specifies one or more pieces of specific content in which a user's interest level is determined as having increased, by determining whether or not the user's interest level in the content has increased; and a notification unit (130) which notifies the user of specific content information indicating the one or more pieces of specific content specified by the specifying unit (120) among the one or more pieces of content indicated in the content availability information.
摘要:
It is to provide a meta data conversion device for converting to meta data in line with a purpose of a content provider when generating meta data for digest viewing or when selecting segmentation meta data. Thus, there is provided a meta data conversion device including: a meta data database for storing meta data; a use condition input part for inputting a use condition for converting the meta data; a scene section information input part for inputting scene section information for converting the meta data; a meta data conversion part for converting selected meta data to the meta data in line with the purpose of the content provider, using the use condition or the scene section information; and a meta data use/reproduction part for reproducing the content using the converted meta data.
