A luminance space conversion section of an information processing apparatus converts an image signal represented in a luminance space corresponding to an SDR into a signal represented in a luminance space corresponding to an HDR, and outputs the converted signal to a synthesis processing section that performs alpha blend processing on an HDR image. In an adjustment mode, a parameter adjustment section allows a display apparatus to display an adjustment image represented in the SDR and adjusts a parameter used for a conversion of the luminance space so that a change in a display image is made small before and after converting the luminance space. The parameter is stored in a conversion parameter storage section after the adjustment and is used when a luminance signal conversion section performs conversion processing.

Information processing apparatus and image processing method

Provided is a moving image generation device, which is configured to: render a frame image including a plurality of image elements; output rendering position information specifying a rendering position within the frame image of a confidential element whose viewing is to be restricted among the plurality of image elements; and generate a moving image by using the frame image while performing display restriction processing on a target region within the frame image which is specified by the rendering position information.

Moving image generation device

To provide an apparatus and method for efficiently displaying image content, which is sent and received between a server and a client, in a correct direction. An image content providing server stores, as property information, original angle information indicating correct directions of image content as metadata of the image content. The server generates content information including the original angle information and sends the generated content information to a client. This allows the client to understand the correct direction of the image content received from the server, and to obtain and display image data in the correct direction by performing rotation processing in the client device based on the obtained information or to request the server to perform the rotation processing.

Information processing apparatus, information processing method, and computer program

The present invention provides an apparatus and method capable of efficiently sending an event corresponding to content to be transmitted from a server to each client. A content providing server assigns a session ID to each client on condition that the server receives an event notification request, which specifies an event URL, from the client and then manages an event notification process on the basis of the event URL and the session ID. When respectively transmitting pieces of content to a plurality of clients, the server determines event information to be transmitted on the basis of each event URL regarding the corresponding piece of content and controls event notification timing for each client on the basis of the corresponding session ID. According to the present configuration, the load of managing data in the event notification process on the server can be reduced and a correct event synchronized with transmission content can be sent to each client.

Information processing apparatus and content information processing method for transmitting content and event information to a client

An apparatus and a method are provided, which enable to perform an improved management processing based on an identifier information of a content on a server. The content providing server sets content-associated unique identifier information as property information that is a component of content-associated metadata, maintains the unique identifier information as content-associated metadata without changing the unique identifier information even if the logical/physical position of a content stored in the storage unit is changed, and maintains a setting value of unique identifier information, which is set associated with a received content, as metadata associated with the received content without changing the setting value of the unique identifier information. By this configuration, even if a content is moved between servers, a client can acquire the content based on the unique identifier.

Information processing device, content management method, content information management method, and computer program

An apparatus and a method capable of efficiently and accurately constructing an access control configuration having high security are realized. Only the MAC address of a controller (client)authorized by a user is authenticated and registered in a MAC address table of a device, and the deviceperforms MAC address filtering for permitting access by the controller(client) which is authenticated and registered in the MAC address table. Furthermore, by making a registration completion notification and by performing version adjustment, a reliable access control configuration is constructed. The device authentication apparatusavoids access from an unauthorized party which is not authenticated and registered, and makes the presence of a server not known to the controller which attempts to illegally perform device authentication. Therefore, access control with high security is realized.

An apparatus and a method are proposed which enable an improved control processing for live streaming distribution of tuner received content from a server to a client. By setting a URL to a channel list as a set of channels, and transmitting a content acquisition request from the client to the server, wherein the channel list URL is designated, to a server, the client can collectively obtain rights to control all content on the channels listed in the channel list. By continuously using an HTTP connection set on the basis of a channel list, the client can switch channels.
