The present invention concerns a method of encapsulating images in a file, wherein the method comprises determining a grouping type based on a capture mode of the images; generating a grouping data structure describing the images as a group, the grouping data structure comprising image identifiers of the images of the group; and embedding the grouping data structure, the grouping type and the images in the file.

Method and apparatus for encapsulating images in a file

A method of encapsulating entities in a file, wherein the method comprises for at least one entity: generating a grouping data structure associated with at least one of the entities, and indicating that the at least one of the entities belong to a same group; encapsulating the grouping data structure and the entities in the file; wherein the grouping data structure is a proprietary grouping data structure comprising an universally unique identifier identifying the type of the proprietary grouping.

Method and apparatus for encapsulating images or sequences of images with proprietary information in a file

A video transmitting apparatus includes a providing unit configured to provide retransmission request information including information for retransmitting video information to be transmitted to a video receiving apparatus, a control unit configured to perform connection control for communication with the video receiving apparatus, a transmitting unit configured to transmit the retransmission request information provided by the providing unit and the video information to the video receiving apparatus, through communication for which connection control is performed by the control unit, a receiving unit configured to receive a retransmission request based on the retransmission request information, the retransmission request being transmitted from the video receiving apparatus, and a retransmitting unit configured to retransmit a specific part of the video information in accordance with the retransmission request received by the receiving unit.

Video transmitting apparatus, video receiving apparatus, and video transmission system

An error-correction data generation apparatus for correcting data to be protected in which an error has occurred, the apparatus includes an input unit configured to input data to be protected and a generation unit configured to generate first correction data to be used in correcting first data to be protected.

Error-correction data generation apparatus and generation method

A communication control apparatus includes a data acquiring unit configured to acquire data to be transmitted to a receiving apparatus, a packetizing unit configured to generate packets using the data acquired by the data acquiring unit, a determining unit configured to compute a possible data transmission delay time of the data packetized by the packetizing unit and determine a transmission interval of the packets based on a result of the computation, and a transmission unit configured to transmit the packets generated by the packetizing unit at intervals that are each within the transmission interval determined by the determining unit.

Apparatus and method for controlling communication

A moving image processing apparatus includes an acquisition unit adapted to acquire moving image data captured with an image capturing unit and image capturing information of the image capturing unit associated with each image frame constituting the moving image data; and an addition unit adapted to add marker information for performing display control of a marker display to the moving image data, in association with an image frame that has been designated from the moving image data.

Moving image processing apparatus and method for acquiring moving image data and performing display control

This invention provides a data processing apparatus, data processing server, and data processing system, which can easily edit data by utilizing features of object-based coding, and can easily generate object-based encoded multimedia data. A multimedia edit & playback terminal () issues an edit instruction of multimedia data to a multimedia edit server () that edits multimedia data consisting of a plurality of object data. A communication client () receives layout information of multimedia data. A playback unit () displays the acquired layout information, and an edit designation unit () designates desired one of the displayed layout information. The designated layout information is output via the communication client ().

Data processing apparatus, data processing server, data processing system, method of controlling data processing apparatus, method of controlling data processing server, computer program, and computer readable storage medium

An image collector/transmitter with the smallest transmission cost is provided which can collect images from image keeping locations with the smallest transmission cost without lowering user services such as selection of an output receiver. Position information indicating the keeping location of image data is managed, and when a print order is issued from an external apparatus, the image data for the print order is collected in accordance with the managed position information, and the collected image data and a print request for the print order are transmitted to a printer controller.

Center server, information processing apparatus and method, and print system

During obtaining new multimedia data, the multimedia data is automatically added to an original file, and a user interface which is used to select whether to record the multimedia data while being added to the original file or to separate the added multimedia data from the original file and create a new file for recording the added multimedia data is provided after the multimedia data is obtained.

Multimedia data processing apparatus and multimedia data processing method

A method and apparatus that, when generating a multimedia file in which encoded data management information is placed at the head of the file, estimates the size needed for the management information in advance and generates a file in which an empty space the size of the estimated size is reserved at the head of the file, with the encoded data directly recorded behind the empty space. If the reserved empty space is insufficient, a new file that reserves a larger empty space is generated and the recorded encoded data is copied and the management information that is ultimately generated is inserted in the head of the file, thus shortening contents creation time and moreover reducing storage space for multimedia contents designed for quick reproduction.

File recording method and file recording apparatus

An object of this invention is to provide a data structure description method and processing method, which can present the contents of data to the user in every devices as much as possible. A data processing method of this invention has a parsing step of parsing a structured document having second data which is included in first data described in a first markup language, is described in a second markup language, and is required to present contents corresponding to the first data, and a processing step of executing, if it is determined in a determination step that a part described in the first markup language of the parsed structured document cannot be understood, a process of data on the basis of a part described in the second markup language.

Data structure, processing method of structured document described using that data structure, program for implementing the method, and storage medium storing the program

This invention provides structured document data and a contents processing method, which can assure high versatility and process each individual required information using an application corresponding to processing performance in each device, so as to solve the problems in the aforementioned conventional description method. Structured document data according to this invention has designation information that designates an item position of a list held in a first document element which holds item information associated with a reference destination of contents as a list, and a second document element that holds information required to present the contents at the reference destination described in the item information corresponding to the designation information.

Structured document data, contents processing method, program for implementing that process, and storage medium storing program

There is provided a print system in which a print instruction is received from an information appliance (IA), a print request is issued to a server in response to the print instruction from the IA, and print data formed by the server is received in accordance with the print request, thereby enabling the print data to be printed from the IA.
