A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of content are provided. The metadata of the content may be efficiently divided for a purpose of use of a terminal based on general media information or specific media information, and may be transmitted to the terminal. A group may include one or more representations of content. The metadata may include a group element, and the group element may provide a summary of attributes of one or more representations included in the group.

Method and device for providing streaming content

Provided is a display apparatus including a light source configured to emit light; a light guide plate configured to diffuse and emit light emitted from the light source; and a local dimming portion configured to pass or scatter light emitted from the light guide plate. The local dimming portion may include an electro-optical material and a plurality of grains having refractive index that changes based on an electric field.

Display apparatus

A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of content are provided. The metadata may include a minBufferTime attribute indicating a minimum amount of initially buffered media content. A terminal may receive content from a server before playback of the content, and may buffer the content by at least the minimum amount. The metadata may include a range attribute that designates a range of a target indicated by a Uniform Resource Locator (URL). The terminal may receive bytes designated by the range attribute from the URL, and may play back the content using the received bytes.

Apparatus and method for providing streaming content

The present disclosure relates to an advertisement effect analysis apparatus and an advertisement effect analysis method. Specifically, the advertisement effect analysis method collects an advertisement viewing history of a user, determines a display state of an advertisement displayed to a user and a user response, and analyzes an effect of the advertisement displayed to the user based on a determination result.

Apparatus for analyzing advertisement effect and method of analyzing advertisement effect

A dynamic packet relay method of a personal area network (PAN) coordinator in a sensor network includes receiving a Child_Register message that includes information about a device associated with a coordinator and building or updating a network hierarchical structure; monitoring reception of a packet or a beacon from the coordinator and determining whether the coordinator is defective or not; and in response to a determination that the coordinator is defective, changing the current coordinator to one of devices belonging to a PAN as a new coordinator.

Dynamic packet relay apparatus and method for sensor network

Disclosed is an apparatus and method for tagging a topic to content. The apparatus may include an unstructured data-based topic generator configured to generate a topic model including an unstructured data-based topic based on content and unstructured data, a viewer group analyzer configured to analyze a characteristic of a viewer group including a viewer of the content based on a social network of the viewer and viewing situation information of the viewer, a multifaceted topic generator configured to generate a multifaceted topic based on the topic model and the characteristic of the viewer group, a content divider configured to divide the content into a plurality of scenes, and a tagger configured to tag the multifaceted topic to the scenes.

Apparatus and method for tagging topic to content

Apparatus and method for providing streaming contents

A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of content are provided. The metadata may include one or more BaseURL elements. Uniform Resource Locators (URLs) of segments forming media may be generated based on the BaseURL elements. Additionally, a URL of a segment may be generated by mapping a BaseURL element among the BaseURL elements to a sourceURL attribute of the segment. Segments indicated by generated URLs may be identical to each other.

A network cooperation-based low power type charged broadcasting set-top box and a controlling method therefor, the set-top box sub-dividing a standby mode of the set-top box into an active standby mode, in which only background functions are processed without processing a main function, and a passive standby mode, in which no functions are processed; extending the passive standby mode occupation time to more than that of the active standby mode; and including a way of transitioning between operating modes by exchanging information regarding the set-top box through an inter-cooperation between a charged broadcasting network and the set-top box, thereby reducing the power consumption of a processor (SoC) which processes multimedia contents and minimizing the power consumption while the set-top box is in standby mode.

Network cooperation-based low power type charged broadcasting set-top box and controlling method therefor

A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of media content are provided. The media content may include a sequence of one or more periods. The metadata may include a start time attribute and/or a duration attribute of each of the periods. The metadata may determine a start time of each of the periods, and a start time of each of segments included in each of the periods. A terminal may access segments included in each of the periods, may decode and render data of media content included in the segments, and may play back the media content.

A method of acquiring an Internet protocol (IP) address to control a standby mode of a set-top box, and the set-top box and a power management server performing the method are disclosed. The method may include determining whether a state of the set-top box changes from a broadcasting state in which a broadcasting service is provided to a passive standby state in which a network connection between the set-top box and a headend providing the broadcasting service is blocked, receiving state information associated with an IP address allocated to the set-top box for the network connection in response to the state of the set-top box changing to the passive standby state, and transmitting, to the set-top box, a state change command to maintain the network connection for the IP address allocated to the set-top box based on the received state information.
