Abstract:
A method and apparatus of processing data to support Augmented Reality (AR) are provided. In the method, an image file including at least a scene description stream, an object descriptor stream, and a visual stream including a real-world medium is received, the scene description stream including an AR node that represents information about at least one piece of AR content used to augment the real-world medium, information about an AR locator and an object descriptor Identifier (ID) is acquired from the AR node, the AR locator describing when the at least one piece of AR content appears and how the real-world medium is augmented with the at least one piece of AR content and the object indicator ID identifying an Object Descriptor (OD) that describes the at least one piece of AR content, and at least one elementary stream descriptor.
Abstract:
An apparatus and a method for transmitting multimedia data in a hybrid network are provided. The apparatus includes a payload part including at least one of first data synchronized according to a time to be reproduced and second data other than the first data, a first header part including information on the payload part, a packet part for generating a packet, the packet part including a second header part including information on the packet, and a transceiver for generating and transmitting a signal including the payload part, the first header part, and the packet part to the hybrid network.
Abstract:
The present invention discloses a server for transmitting and receiving messages for a signaling (S) layer in MMT (Moving Picture Experts Group Media Transport), which includes a first sub-layer of the S layer for producing first messages to provide information necessary for the use of MPEG, a second sub-layer of the S layer for producing second messages to provide information used for delivering MPEG media, and a delivery (D) layer for making external and internal deliveries of the first and the second messages, wherein each of the first and the second messages includes at least one field corresponding to each of the message type, version, length, extension field and payload.
Abstract:
An apparatus and a method for transmitting a multimedia frame through a heterogeneous network in a broadcast system supporting a multimedia service based on an internet protocol are provided. The method includes generating header information including a frame identifier distinguishing a multimedia frame and information measuring a quality of a connection service between network layers and end-to-end network capabilities, and combining the header information and multimedia data to configure the multimedia frame.
