A multimedia middleware apparatus using metadata, a control method and a storage medium are provided which can receive metadata in multimedia middleware provided in a terminal, easily add/delete/change a service, and effectively maintain and manage middleware components. When an open multimedia terminal processes multimedia contents, a multimedia middleware service structure for expressing information of a name, configuration, version and application programming interface (API) update is configured in the form of metadata. Lists of standard and non-standard services of multimedia middleware are then generated and managed.

Multimedia middleware apparatus using metadata, method for controlling multimedia middleware, and storage medium thereof

A security management method in multimedia middleware of a terminal that can download a multimedia service provided from an external entity. The security management method includes if there is an access request for a particular multimedia service, determining whether there is a corresponding multimedia service; if the access-requested multimedia service does not exist in middleware of the terminal, performing negotiation for secure session setup with the external entity; setting up a secure session to the external entity using a security parameter selected as a result of the negotiation; and receiving information for the download from the external entity through the secure session, and determining whether to execute the download.

Multimedia content is provided continuously for multiple users each potentially moving to a different place while enjoying it together. The system includes a network for transmitting preferably IP-format data, a first device for outputting particular multimedia content received through the network, and a second device for outputting a second multimedia content prepared for, and received upon requesting, continuous provision of the particular multimedia content through the network. A contents server delivers the particular multimedia content and the second multimedia output to the first and second devices, respectively. The second multimedia content consists of the part of the particular multimedia content remaining to be transmitted at the point of time at which the second device requested the continuous provision of the particular multimedia content.

Providing multimedia content continuously for multiple users so as to accommodate movement to one or more different audience locations

A metadata transmitter synchronized with multimedia contents comprises: a multimedia contents authoring unit for generating and editing multimedia contents; a multimedia contents format converter for compressing the multimedia contents, converting them into a transmission format, and outputting them; a metadata authoring unit for generating and editing metadata for describing the multimedia contents, the metadata including transmission types and transmission information; a metadata format converter for converting the metadata into binary codes, converting the converted metadata into a synchronization format for synchronization with the multimedia contents and a transmission format, and outputting them; and a multiplexer for multiplexing the multimedia contents format and the metadata format respectively output from the multimedia contents format converter and the metadata format converter into a stream, and outputting it.
