    摘要: A method, a media renderer device and a media source device for providing content over a network, and a message structure for controlling a real-time transport protocol (RTP) are provided. The method includes transferring a hypertext transfer protocol (HTTP) control command generated so that content is provided from a media server providing content using a RTP. The HTTP control command can use an HTTP POST command or an HTTP PUT command. When transferring AV content using a RTP, the content is controlled using an existing HTTP not a Real-Time Streaming Protocol (RTSP). Accordingly, a RTP can be more easily supported.

    摘要: A live content management method, a source device, and a sink device are provided. The live content management method includes storing live content in a storage unit of a source device if the transmission of the live content from the source device to a sink device is temporarily stopped. The live content management method may also include transmitting the live content stored in the storage unit of the source device to the sink device and then transmitting live content currently being broadcasted to the sink device via the storage unit of the source device, when receiving a request for resuming the transmission of the live content stored in the storage unit of the source device before a time-out for a command to stop the transmission of the live content stored in the storage unit of the source device. Accordingly, it is possible to provide various data transmission scenarios for a home network environment by efficiently managing live content even when the transmission of the live content via a home network has been temporarily stopped.

    摘要: A method and apparatus where a source delivers graphics data to a target, which receives and displays the graphics data. The source of the graphics data controls how the graphics data is to be displayed at the target. The source transmits a display control signal prescribing a manner in which the video signal is to be displayed in relation to the graphics data. A target receives the video signal, the graphics signal, and the display control signal, and combines the video signal and the graphics data in the manner prescribed by the display control signal to form a combined display at the target.

    摘要: An apparatus and method for allocating channel time for each application in a single superframe when applications such as wireless USB and IEEE 802.2, which are implemented in a MAC layer, coexist on a wireless PAN. The apparatus includes a beacon generating module for generating a superframe; a duration adjusting module for adjusting a duration of the superframe to be a multiple of a frame of an upper application layer of a device; a channel time dividing module for comparing an allowable size of maximum CTA in the frame of the upper application layer of the device with a size of isochronous CTA of another device and dividing the CTA, if necessary; and a channel time relocating module for comparing a super-rate of CTA previously located in the superframe with a super-rate of CTA to be newly added and relocating the newly added CTA.

    摘要: A live content switching method, a source device, and a sink device are provided. The method includes switching from first content to second content by using a dummy connection, the second content using the same resource of the source device as the first content. Accordingly, by using dummy connections set between a source device and a sink device, it is possible to switch the sink device from one live content to another live content without the need to cut off existing connections set between the source device and the sink device.
