20080250101 | MULTIMEDIA DATA TRANSMITTING APPARATUS AND MULTIMEDIA DATA RECEIVING APPARATUS - To provide, in a multimedia content server which stores multimedia data and transmits the stored multimedia data to a terminal, a technique which allows the terminal to implement a data broadcast even when random access for trick play, and the like, is performed. Upon receiving a data transmission request from a multimedia data receiving apparatus, a multimedia data transmitting apparatus transmits the requested multimedia data and definitely inserts data required for data broadcasting or transmits data for data broadcasting, separately from the multimedia data, thereby enabling the multimedia data receiving apparatus to obtain the data required for data broadcasting. | 10-09-2008 |
20080250461 | MULTIMEDIA DATA TRANSMITTING APPARATUS AND MULTIMEDIA DATA RECEIVING APPARATUS - To provide, in a multimedia content server which stores multimedia data and transmits the stored multimedia data to a terminal, a technique which allows the terminal to properly detect and process version up of section data even when random access for trick play, and the like, is performed. Upon receiving a data transmission request from a multimedia data receiving apparatus, a multimedia data transmitting apparatus transmits the requested multimedia data and notifies data necessary for obtaining an update-point of section data included in the multimedia data or a URI which enables the obtaining of the data, to the multimedia data receiving apparatus. | 10-09-2008 |
20090193101 | MULTIMEDIA DATA TRANSMITTING APPARATUS AND MULTIMEDIA DATA MANAGEMENT METHOD - To provide, in a multi-user environment, a multimedia data transmitting apparatus which prevents a content for which playing is paused by a user from being deleted by another user, and allows playing to be resumed. The multimedia data transmitting apparatus includes: a content managing unit which holds a content and an attribute thereof; and a judging unit which judges, when deletion of the content is requested, whether or not deletion is possible for the content, based on the attribute. The judging unit judges that deletion is possible when the attribute does not indicate either “currently played” or “playing paused”, and to judge that the deletion is not possible when the attribute indicates “currently played” or “playing paused”, and the content managing unit deletes the content when said judging unit judges that deletion is possible. | 07-30-2009 |
20090222867 | Broadcast receiving apparatus, video storing apparatus, and multimedia delivering system - An apparatus is provided which supplies cached data in a house which does not require a large-space storage device, is a broadcast receiving apparatus that is connected to a network and that receives multimedia data including at least one of video and audio, from a device installed in a broadcast station. The apparatus includes a data receiving unit that receives the multimedia data from the device installed in the broadcast station, a selecting unit that selects one of the video storing apparatuses each of which stores multimedia data, an information communicating unit that transmits a request for storing multimedia data to the video storing apparatus selected by the selecting unit, and a data output unit that outputs the multimedia data received by the data receiving unit to the video storing apparatus selected by the selecting unit via the network. | 09-03-2009 |
20090300231 | DATA OUTPUT DEVICE, EQUIPMENT CONTROL DEVICE, AND MULTIMEDIA DELIVERY SYSTEM - A technology which can appropriately resume reproduction of paused content from a terminal in another terminal in a multimedia delivery system made up of a multimedia content server and plural terminals connected to a network. | 12-03-2009 |
20100262674 | DATA TRANSMITTING APPARATUS, DATA RECEIVING APPARATUS, DATA TRANSMITTING METHOD AND DATA RECEIVING METHOD - A data transmitting apparatus, which implements a RESUME function which is capable of properly setting a resume position and capable of setting plural resume positions, executes a Java™ application program and includes: a memory for storing content and content attribute information; a network unit which transmits a content to a data receiving apparatus; an action request receiving and responding unit which receives an update request indicating a resume position, from the data receiving apparatus; and a resume position managing unit which updates content attribute information stored in the memory in accordance with the received update request, so that such resume position and a resume position identifier are included in the content attribute information. | 10-14-2010 |
20120311645 | VIDEO PROCESSING DEVICE, METHOD, RECORDING MEDIUM, AND INTEGRATED CIRCUIT - A video processing device receives at least a supplementary display object playback stream and a data block, the supplementary display object playback stream containing an encoded supplementary display object to be displayed along with a 3D video image, and the data block including identifying information for 3D display of the supplementary display object by a processing unit. Before the content of the supplementary display object playback stream is referred to, the identifying information is extracted from the data block and the processing unit for 3D display of the supplementary display object is determined. The determined processing unit processes the supplementary display object playback stream to create and output a right-view supplementary display object and a left-view supplementary display object. | 12-06-2012 |
20130024898 | CONTENT PLAYBACK DEVICE, CONTENT PLAYBACK METHOD, CONTENT PLAYBACK PROGRAM, AND CONTENT PROVIDING SYSTEM - To provide a content playback device capable of, when playing back a content distributed in a streaming format via a network whose view mode is selectable among a plurality of view modes, presenting to a user the switchability between the view modes, thereby to improve the user's convenience. The content playback device includes a reception unit that receives, from the content distribution system, control information indicating a plurality of view modes selectable for viewing the video content, a presentation unit that presents, to a user, the view modes as options of a view mode for viewing the video content, an input reception unit that receives an input selecting one view mode among the view modes from the user; and a request unit that requests the content distribution system to distribute the video content in the streaming format, by transmitting information indicating the selected view mode to the content distribution system. | 01-24-2013 |
20130291025 | CONTENT PLAYBACK DEVICE, METHOD FOR PLAYING BACK CONTENT AND CONTENT DELIVERY SYSTEM - A content playback device reduces user discomfort, relative to conventional devices, when playback is interrupted and resumed after switching viewing modes, pieces of content representing different viewing modes for a common product, and differing in video length or having other differences. The content playback device receives and plays back streaming content from a content server delivering two pieces of content having different viewing modes for the common product, and comprises: a selection unit selecting a viewing mode; a determination unit determining whether playback of a first piece of content not having the selected viewing mode was interrupted; a conversion unit converting, when the determination unit has determined affirmatively, a playback interrupt position into a corresponding position in a second piece of content having the selected viewing mode; and a request unit making a request to the content server for transmission of the second piece of content from the corresponding position. | 10-31-2013 |
20140079368 | DISPLAY DEVICE AND TRANSMISSION DEVICE - A display device comprising: a reception unit; a display unit; a storage unit; and an acquisition unit. The reception unit receives a stream containing a plurality of video frames and first display timing information specifying a display timing of each video frame. The display unit displays each video frame at a corresponding display timing specified by the first display timing information. The storage unit stores an image and second display timing information specifying a display timing of the image. The acquisition unit acquires correction information specifying a correction amount for correcting the display timing of the image and thereby enabling the image to be displayed in synchronization with the video frames displayed by the display unit. The display unit further displays the image at a corrected display timing determined by correcting the display timing of the image by using the correction amount specified by the correction information. | 03-20-2014 |
