20090265479 | DUAL-TYPE OF PLAYBACK FOR MULTIMEDIA CONTENT - Using multimedia data for both continuous playback and streaming playback purposes, including: encoding an elementary stream of multimedia content into a fixed length of a group of pictures; multiplexing the encoded multimedia content into a transport stream; locating data offsets of each GOP header inside the transport stream; and uploading the data offsets along with the transport stream to a server. Continuous and streaming playback of multimedia content. | 10-22-2009 |
20090269042 | CPS UNIT MANAGEMENT IN THE DISC FOR DOWNLOADED DATA - An information processing device comprising: a data processing unit configured to load a disk, which stores content that is divided into content usage control units, and to execute processes for reading the content; and a local storage unit configured to store subsequential data obtained and/or generated subsequentially, wherein the data processing unit is configured to perform processes to: select a title that is an index for reading the subsequential data from dummy titles stored in advance on the disk; set the title as a title for the subsequential data; and store the subsequential data in the local storage unit. | 10-29-2009 |
20090271411 | BINDING UNIT MANIFEST FILE - An information processing device including: a storage unit for storing a data file including readable content, and a control file including control information corresponding to the data file; and a data processing unit configured to use a filename conversion table, which stores filename conversion information, to convert the filename of a file stored in the storage unit into a virtual file system (VFS) name, to construct a VFS that includes storage data of a disc and storage data of the storage unit, and to perform a data reading process; wherein the data processing unit: compares the control information stored in the control file and data stored in the storage unit, and reads and/or updates the filename conversion table to reconcile the control information stored in the control file and the stored data in the storage unit. | 10-29-2009 |
20110109730 | STEREOSCOPIC OVERLAY OFFSET CREATION AND EDITING - Adjusting overlay positioning in stereoscopic video, including: receiving overlay data including a plurality of overlays, each overlay having a lateral axis value, a vertical axis value, and a depth value; receiving and displaying the stereoscopic video to a user as at least one of a video preview display and a stereoscopic display, each display including an overlay from the overlay data, wherein a position of the overlay in each display is based on the lateral axis value, the vertical axis value, and the depth value of the overlay, and wherein the video preview display includes interfaces for adjusting the position of the overlay in each display; receiving input from the user related to the depth value of the overlay; and adjusting the position of the overlay in the video preview display based on the input from the user. | 05-12-2011 |
20120128324 | 3D AUTHORING TOOL ENSURING NO BUFFER UNDERRUN UPON JUMPS - Systems and methods are provided to implement a technique for providing 3D content, such as on optical media like Blu-ray® discs. In one implementation, a 3D authoring tool executing on a computer system manages how to construct an image for replication where the image handles jumps without buffer underruns, the jumps caused by layer switching or by moving from or to branches in a multi-branch story line. | 05-24-2012 |
20150326393 | CONTENT INDIVIDUALIZATION - Content individualization, including: encrypting a first part of a source data set using a first key creating a first encrypted data set; encrypting a second part of the source data set using a second key creating a second encrypted data set; encrypting the second part of the source data set using a third key creating a third encrypted data set; and combining the first encrypted data set, the second encrypted data set, and the third encrypted data set to form a final encrypted data set. Key words include watermarking and content individualization. | 11-12-2015 |
20160036885 | CONTENT FORMAT CONVERSION VERIFICATION - Content conversion verification, includes: converting, at a first computer system, an original content file to a target format, generating a converted content file in the target format; generating a checksum for the converted content file; and sending the original content file and the checksum to a second computer system. Key words include content verification and checksum. | 02-04-2016 |
20160057112 | INFORMATION PROCESSIING DEVICE, INFORMATION PROCESSING METHOD, AND PROGRAM - Provided is an information processing device including: a data processing unit that performs a content playback process; and a communication unit that communicates with a server, wherein the content is content that has a segment region configured with a plurality of pieces of variation data which can be respectively decrypted by different keys, and for which a plurality of playback paths can be configured according to variation data which is selected as a playback object, wherein each piece of variation data is data for which a variation data identifier can be analyzed from decrypted data, and wherein the data processing unit receives playback path information which is allowed to be played from the server through the communication unit, and selects variation data from the segment region so as to perform content playback, according to the playback path information received from the server. | 02-25-2016 |
20160057491 | INFORMATION PROCESSING DEVICE, INFORMATION RECORDING MEDIUM, INFORMATION PROCESSING METHOD, AND PROGRAM - Provided is an information processing device including: a data processing unit that performs format conversion of converting MPEG-2 TS format data into MP4 format data, wherein the MPEG-2 TS format data is data that includes each segment region having a plurality of pieces of variation data decryptable with different keys, and wherein the data processing unit selects encrypted MP4 variation data from the segment region of the MPEG-2 TS format data and stores the MP4 variation data as MP4 format structure data in an MP4 file, while the encrypted variation data remains, without performing a decryption process and a re-encryption process for the selected MP4 variation data. | 02-25-2016 |
20160064028 | INFORMATION PROCESSING DEVICE, INFORMATION RECORDING MEDIUM, INFORMATION PROCESSING METHOD, AND PROGRAM - An information processing device includes: a data processing unit which executes a reproduction process of recorded data of a disc, in which the data processing unit reads disc type information that is recorded on the disc, and ascertains a recorded data configuration of the disc based on the disc type information that is read, and executes data reading-out and reproduction processes according to a reading-out rate corresponding to the ascertained recorded data configuration. | 03-03-2016 |
