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： 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.
摘要翻译：提供了一种用于通过网络提供内容的方法，媒体渲染器设备和媒体源设备，以及用于控制实时传输协议（RTP）的消息结构。该方法包括传送生成的超文本传输协议（HTTP）控制命令，使得使用RTP提供内容的媒体服务器提供内容。 HTTP控制命令可以使用HTTP POST命令或HTTP PUT命令。当使用RTP传送AV内容时，使用现有的HTTP而不是实时流协议（RTSP）来控制内容。因此，可以更容易地支持RTP。

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.
摘要翻译：提供实况内容管理方法，源设备和宿设备。如果从源设备到宿设备的实时内容的传输被暂时停止，则实时内容管理方法包括将实况内容存储在源设备的存储单元中。实时内容管理方法还可以包括将存储在源设备的存储单元中的实况内容发送到宿设备，然后在接收到请求时通过源设备的存储单元将当前正在广播的现场内容发送到宿设备用于在用于停止发送存储在源设备的存储单元中的实况内容的命令的超时之前恢复存储在源设备的存储单元中的实况内容的传输。因此，即使当通过家庭网络的实时内容的传输已被暂时停止时，也可以通过有效地管理实况内容来为家庭网络环境提供各种数据传输场景。
