The box including the media data of the second content and the box including the metadata information for playing the media data of the second content each includes identification information for the second content.
摘要:
A system and method for providing content in a digital broadcasting system are provided. The system includes a server for, after a lapse of a buffering time of a segment of the content, storing the segment, and for transmitting an updated Multimedia Presentation Description (MPD) including Uniform Resource Location (URL) information indicating a location where the segment is stored, and a client device for receiving the updated MPD, and for acquiring the segment stored in the location indicated by the URL information included in the updated MPD.
摘要:
An apparatus and a method for providing an adaptive multimedia service in a mobile communication system are provided. The method of providing a multimedia service includes collecting user-preference-aware information, device-capability-aware information, and network-aware information, generating a packet according to a correlation among the user-preference-aware information, the device-capability-aware information, and the network-aware information, and providing a multimedia service according to the generated packet.
摘要:
A method and apparatus for transmitting and receiving rich media content. A creator creates configuration information of each node formed in a hierarchical structure in a changeable format in which a driver can change the configuration information, and transmits content including the configuration information of each node to the driver. A driver receives the content, determines whether configuration information of each node formed in a hierarchical structure in the received content is created in the changeable format, reconfigures each node when the configuration information is created in the changeable format, and performs an application on the reconfigured node.
摘要:
An apparatus includes a storage unit to receive and store an image file, a processor to parse a media data field of the image file including one or more image data samples and to parse a media header field including an image type data field indicating whether each of the one or more image data samples is one of 2 dimensional (2D) image data and 3 dimensional (3D) stereoscopic image data to generate an image corresponding to one of a 2D image and a 3D stereoscopic image based on the image type data field of the image file, and a display unit to display the generated image according to the image type data field of the image file.
摘要:
Disclosed are a system and a method for generating and regenerating three-dimensional (3D) image files based on two-dimensional (2D) image media standards. The system includes a 3D image file generating device for generating a 3D image file including a data area, which includes a first image data and a second image data, the second image data being synchronized with the first image data so as to be used for generating a 3D image and undergoing a data conversion process based on the first image data, a header area including information of the first image data, and a metadata area including information of the second image data, and a 3D image file regenerating device, which parses information of the first and second image data when a 3D image file is inputted so as to extract the first and second image data, restores the second image data through a data conversion process, and synthesizes the first image data and the restored second image data so as to regenerate the 3D image file.
摘要:
A method for creating content in a broadcasting system that provides an Internet protocol (IP) based multimedia service, the method comprising combining multiple assets into a package, the multiple assets being transferred from an upper layer and having multiple contents, and adding configuration information for multiplexing the multiple assets to the package and then transferring the package to a lower layer, wherein the configuration information comprises a list of assets contained in the package, composition information including information about relationships among the multiple assets, and a transport characteristic relating to delivery paths of the multiple assets.
摘要:
Methods and apparatus are provided for transmitting adaptive streaming mechanism-based content. Representations, which include content components, are combined into a group. At least two of the group, a representation, and a content component type are combined into a subset. The subset is transmitted.
