Abstract:
Disclosed is a method for generating a substream ID usable in transmitting media content based on a plurality of scenarios, and allocating the substream ID for transmitting media. A method for allocating an ID for transmitting media content comprises: a step of generating a substream ID containing information required for transmitting the media content based on a certain scenario from among a plurality of scenarios; and a step of transmitting the substream ID to a client. According to the present invention, a header for the transmission of media may be simplified, media content may be transmitted regardless of the number of ports, number of servers, and presence/absence of additional information, an application to be introduced in the future may be used, and backward compatibility for an existing media content transmission system may be provided.
Abstract:
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.
Abstract:
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.
Abstract:
Provided is an apparatus and method for transmitting and receiving a streaming service. The apparatus and method for transmitting and receiving a streaming service may use a light multimedia file suitable for a Hypertext Transfer Protocol (HTTP) streaming service. Using an HTTP hint track, an International Organization for Standardization (ISO) file generated in a non-interleaved storing scheme that is unsuitable for an HTTP streaming service may be converted into an ISO file based on an interleaved storing scheme that is suitable for an HTTP streaming service. An ISO file may include multiple media tracks for supporting multiple bitrates and resolutions. Chunk data of media tracks that provide multiple multimedia qualities may be effectively acquired, and a light ISO file suitable for an HTTP streaming service may be generated by storing the acquired chunk data in an interleaved scheme.
Abstract:
Provided are an image encoding and decoding apparatus and method, which can effectively transmit a large capacity image. The image encoding apparatus generates a plurality of actual images with respect to an input image, and generates a difference image capable of predicting another actual image using one actual image, thereby effectively reducing an amount of data before encoding the input image.
Abstract:
The present invention provides haptic steering wheel switch apparatus including: a haptic wheel housing unit disposed on a steering wheel of a vehicle; a circuit board unit disposed in the haptic wheel housing unit; and a haptic wheel device unit including a haptic wheel device actuator establishing an electrical connection with the circuit board unit and including a haptic shaft, a haptic knob connected to the haptic shaft and exposedly disposed on one surface of the haptic wheel housing unit, and a haptic wheel device sensing unit for detecting a rotating state of the haptic shaft, wherein the haptic knob achieves a rotary operation on a plane formed by the steering wheel of the vehicle, the haptic wheel device actuator moves in a longitudinal direction of the haptic shaft, and a button switch unit operating vertically and independently of the haptic knob is provided outside the haptic knob.
Abstract:
A method of authenticating at least one piece of content provided to an image forming apparatus in which at least one consumable is disposed includes determining whether the at least one consumable includes authentication information of the at least one piece of content, displaying the at least one piece of content on a user interface according to a license policy corresponding to the authentication information, selecting at least one piece of content from the at least one piece of content displayed on the user interface, and executing the selected at least one piece of content.
Abstract:
Disclosed is an apparatus and a method for automatically changing the broadcast channel for a mobile communication terminal adapted to receive digital multimedia broadcasts. The apparatus includes a memory unit for storing an adjacent area database and an area-wise broadcast channel database; a search unit for searching for broadcast channels and receiving broadcasts; and a control unit for determining the received field strength of at least one adjacent area frequency based on the adjacent area database during digital multimedia broadcast playback, and when a predetermined threshold is exceeded, determining that a movement into a corresponding adjacent area is occurring, the control unit controlling the search unit to search through broadcast channels of the adjacent area in the area-wise broadcast channel database to find a broadcast channel identical to a broadcast channel used for playback before the movement into the adjacent area.
