Abstract: Laser hazard at disconnection can be prevented with a simple structure. A tubular connector exterior, and a block that is incorporated on one end side of the connector exterior and on which a light emission portion or a light incident portion is mounted toward the other end side are provided. The light emission portion or the light incident portion is mounted on the block so that the optical axis direction thereof is tilted relative to the longitudinal direction of the connector exterior. The light emission portion is a lens through which light output from a light transmission path is collimated and emitted. At least part of the collimated light emitted through the lens is incident on a light diffusion portion provided inside the connector exterior.

Abstract: To enable an HDR image and an HDR image metadata to be stored in an MP4 file, and a reproduction device to reproduce an optimum HDR image based on metadata. In generating the MP4 file that stores HDR image data, the HDR image metadata is recorded in the MP4 file. An HDR image metadata storage box is set to a trak box or a traf box in the MP4 file, and the HDR image metadata is stored. The reproduction device acquires the HDR image metadata stored in the MP4 file, determines whether executing a conversion process of the HDR image read from. the MP4 file according to the acquired metadata and display function information of the display unit, and executes an output image generation process according to a determination result.

Abstract: A lock mechanism of an optical connector suited for practical use and having robustness is provided. A first optical connector, a second optical connector, a first lock member, and a second lock member are equipped. The first optical connector is attached to an electronic device, and corresponds to a so-called receptacle. The second optical connector is attached to an end portion of an optical cable, is fittable to the first optical connector, and corresponds to a so-called plug. The first lock member is attached to the electronic device at a position corresponding to the first optical connector in such a manner as not to prevent fitting of the second optical connector to the first optical connector. The second lock member is attached to the optical cable at a position corresponding to the second optical connector in such a manner as not to prevent fitting of the second optical connector to the first optical connector. In addition, the second lock member is fittable to the first lock member in a state of fitting between the first optical connector and the first optical connector.

Abstract: [Object] To propose an optical communication connector, an optical communication cable, and an electronic device being novel and improved that have excellent maintenance properties and can prevent parallel light (collimated light) from being directly emitted to the outside of an optical connector during non-optical coupling. [Solution] There is provided an optical communication connector device including: a collimating lens configured to collimate light from an optical transmission path; a refracting section arranged on a leading end side with respect to the collimating lens, and configured to refract and eject light from the optical transmission path ejected from the collimating lens; and a scattering section configured to scatter at least a part of the light ejected from the refracting section.

Abstract: A configuration capable of performing reliable source analysis of illegal copy content using content in which a reproduction path is settable is implemented. Content in which an individual segment region including a plurality of pieces of variation data which include different identification information embedded therein and are decryptable using different keys and a common segment region including single data are provided, and variation data is configured with an aligned unit is set. A content reproducing device calculates a reproduction path by applying a device key and selects and reproduces an aligned unit corresponding to the reproduction path on the basis of a variation data identifier recorded in an adaptation field in a plain text region at the head of a plurality of aligned units constituting the variation data.
