  • Patent number: 10733963
    Abstract: 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.

  • Patent number: 9002779
    Abstract: 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.

  • Patent number: 7996538
    Abstract: 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.

  • Patent number: 7792865
    Abstract: 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.
