    摘要： A media data transmission and processing system and a method for operating the system is a suggested. The media data transmission and processing system comprises two independent processing cards. The system is configured such that if one of the two processing cards fails, then the system is still capable of one downstream data stream. A key role in place the Master Slave configuration between the two processing cards. The Master processing card is configured to assign a new PTP timestamp and packet counter number to an IP packet currently processed in the Master processing card and to communicate the new PTP timestamp and packet counter number to the Slave processing card, which assigns the same PTP timestamps and packet counter numbers as the Master processing card.

    摘要： A method for controlling a robotic camera (106) capturing a portion of a playing field (100) is suggested. An image region of interest is determined in a reference image of the playing field. The image region of interest is determined by artificial intelligence (111). The image region of interest is associated with a physical region of interest on the playing field. From the physical region of interest control parameters for the robotic camera (106) are deduced such that the robotic camera captures the physical region of interest on the playing field. As a result it is achieved that the robotic camera automatically captures the most interesting scene on the playing field. Furthermore, a camera system is suggested that implements the method.

    摘要： It is provided a method for content presentation of a 3D video and a complementary 3D content, wherein the 3D video comprises a left view and a right view and the complementary 3D content comprises a left view and a right view. The complementary 3D content is associated in time with at least a portion of the 3D video, the method comprises the steps of temporally multiplexing the left view and the right view of the portion of the 3D video and the left view and the right view of the complementary 3D content to produce multiplexed data; polarizing the multiplexed data to produce polarized data; presenting the polarized data.

    摘要： The present invention provides a method and apparatus for creating a 3D model from an input 3D model based on repetitive structures of the input 3D model. The Method comprises: detecting repetitive structrures of the at least one component of the input 3D model and hierarchical relationship of the repetitive structrures, each repetitive structure comprising a component set as a representative and one or more components, if any, set as an instance; determining a relative transformation among all representatives and instances of all the repetitive structures of the input 3D model; and updating relevant components of the input 3D model according to a change of a representative in the repetitive structrures and recalculating the poses of the updated components as a function of the determined relative transformation to create the 3D model.

    摘要： A method of operating a video/audio processing apparatus is suggested. The system comprises a plurality of processing units connected by data links for communicating packetized data. The method comprises the following steps: receiving the input signals according to user requests; providing resources for processing, routing, and transmitting signals; providing input signals; routing the input signals to selectable destinations according to user requests; monitoring the required resources for processing and/or routing the signals; comparing the required resources with available resources; and issuing a warning message to the user if the required resources exceed the available resources of the system. Also a processing apparatus is suggested which is adapted for executing the method.

    摘要： To estimate content complexity of a video, energy of prediction residuals is calculated. The prediction residuals are usually smaller when the video is less complex and more predictable. Scales of prediction residuals also depend on encoding configurations, for example, I pictures usually have larger prediction residuals than P and B pictures even when the contents are very similar and thus have similar perceived content complexity. To more closely reflect the content complexity, alignment scaling factors are estimated for different encoding configurations. Based on the energy of prediction residuals and alignment scaling factors, an overall content unpredictability parameter can be estimated to compute a compression distortion factor for the video. The compression distortion factor, combined with slicing and freezing distortion factors, can be used to estimate a video quality metric for the video.
