  • Publication number: 20200329266
    Abstract: For enabling a reception apparatus to appropriately know the direction of a video, a CPU of a video transmission apparatus generates, for two or more second videos corresponding to two or more different directions generated from a first video, direction data indicating the two or more directions. The CPU also generates transmission URLs to be used by the reception apparatus for acquiring any of the second videos, and generates metadata in which the second videos are associated with the transmission URLs and the direction data.

  • Patent number: 7865833
    Abstract: 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 (201) issues an edit instruction of multimedia data to a multimedia edit server (202) that edits multimedia data consisting of a plurality of object data. A communication client (214) receives layout information of multimedia data. A playback unit (212) displays the acquired layout information, and an edit designation unit (211) designates desired one of the displayed layout information. The designated layout information is output via the communication client (214).

  • Patent number: 7584206
    Abstract: 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.
