static content indication data
Vertaling van "static content indication data" in Chinees
静态内容显示数据
静态内容指标数据
communicating the static content indication data to a wireless access device for use in wireless transmission of the video stream.

generating static content indication data representing the static portion of the video stream; and
生成代表视频流的静态部分的静态内容显示数据；并且
In step 702 of this embodiment, static portion(s) of video content are identified during the generation of (including assembly of) a video stream that is provided to a transmitting device such as a wireless dongle for communication to other devices. Next, in step 704, indications of static video content are communicated to an encoding function of the transmitting device (e.g., via a standardized communication protocol interface or a standardized communication interface modified to support static content indication data). Upon receipt, the transmitting device may utilize such indications (step 706) to create a static indication within the compressed video stream to efficiently indicate which portion(s) of each frame (or picture) is (are) static, or to skip or remove static video content in a video stream such that it is not transmitted to a receiving device.
在该实施例的步骤702中，生成（包括汇编）视频流期间对提供给传输装置（例如，无线电子狗），以与其他装置通信的视频内容的静态部分进行识别。接下来，在步骤704中，静态视频内容的指标传输给传输装置的编码功能（例如，通过为了支持静态内容显示数据而修改的标准化通信协议接口或标准化通信接口而进行）。接收时，所述传输装置可利用这些指标（步骤706）在压缩视频流内创建静态指标，以有效显示每个帧（或图像）的静态部分，或跳过或消除视频流中的静态视频内容，使其不会传输给接收装置。
Alternatively, the video content and (in some embodiments) static content indication data may be communicated to the wireless access device 602 by various means such as those described above, including through a broadband internet/wide area network (WAN) connection. In one embodiment, the wireless access device 602 may be coupled to a cable or satellite set top box or the like by a standardized interconnect/interface such as an HDMI cable, an Ethernet cable, a high bandwidth wireless link (e.g., a WiGig or WirelessHD compliant link) capable of transmitting standard or high definition video content, or various combinations of such technologies.
可替代地，所述视频内容和（某些实施例中的）静态内容显示数据可通过各种方式，例如，上文所述的方式，包括宽带互联网/广域网（WAN）连接而传输给无线接入装置602。在一个实施例中，所述无线接入装置602可通过标准化互连线路/接口，例如，HDMI电缆、以太网电缆、能传输标准或高清视频内容的高带宽无线链路（例如，符合WiGig或WirelessHD的链路），或这些技术的各种组合而与有线或卫星机顶盒等耦合。
Methods for removing redundancies in a video stream based on detection of static portions of the video stream prior to encoding of the video stream for wireless transmission. In various embodiments, the generation and buffering of a video stream having a series of video frames is monitored to detect static portions of the video stream. Static content indication data representing static portions of the video stream are communicated to a wireless access device for use in transmission of the video stream. Communication of the static content indication data may occur via a standardized communication interface and protocol. In one embodiment, static video content may be identified by ascertaining portions (e.g., windows in a rendered desktop) of a video frame buffer that are actively addressed by content generators such as software applications, a graphics processing unit, etc.
基于在视频流编码前检测视频流的静态部分而消除视频流中的冗余，以进行无线传输的方法。在各个实施例中，监控具有一系列视频帧的视频流的生成和缓冲，以检测视频流的静态部分。代表视频流的静态部分的静态内容显示数据与无线接入装置通信，以传输视频流。静态内容显示数据的通信可通过标准通信接口和协议进行。在一个实施例中，静态视频内容可用由软件应用、图形处理单元等内容生成器主动寻址的视频帧缓冲器的确定部分（例如，所示桌面的窗口）进行识别。

FIG. 6 is a block diagram representation of a communication network 600 utilizing static content information generated by components of a video source in accordance with alternate embodiments of the present disclosure. In this embodiment of the invention a content creation module 608 includes static content identification functionality 609 to identify (or help identify) and signal static video content. As will be appreciated, the content creation module 608 may take many forms, including a Graphics Processing Unit (GPU) that assembles and/or generates a video stream for transmission to a wireless device. For example, a GPU in a gaming console or like device may produce a rendered video steam and static content indication data that is provided to the wireless access device 602 via a standardized interconnect/interface 610.

Static content indication data produced by static content signaling 804 might comprise, for example, start and stop flags that are synchronized (e.g., through the use of time stamps) with the video stream and indicate the beginning and end of detected static content. In some embodiments, the static content indication data may be provided to the video encoding function of the wireless access device 822 via a standardized interconnect interface 820 which is also used to communicate video frame data. If supported by a recipient wireless access device, the static content indication data may be provided through one or more optional channels of a standardized interconnect interface/protocol, or embedded in the video stream itself.
静态内容信令804功能生成的静态内容显示数据可包括，例如，与视频流同步（例如，利用时间戳），表示检测静态内容的开始和结束的开始和停止符号。在某些实施例中，静态内容显示数据可通过也用于传输视频帧数据的标准化互连接口820提供给无线接入装置822的视频编码功能。如果接收方无线接入装置支持，所述静态内容显示数据可通过标准化互连接口/协议的一个或多个可选信道提供，或嵌入视频流本身内。
