摘要： A system and method is provided for performing lossless switching in a redundant multicast network. An exemplary method includes receiving a primary media stream and a redundant media stream over different forwarding network paths by network ports of a receiver communicatively coupled to an A/V device. Furthermore, the receiver outputs media data of the media streams to the A/V device to be presented thereon. In response to a control signal to switch the receiver to a new primary media stream, the method disconnected either the primary or the redundant media streams from the respective network port of the receiver receiving that stream. Furthermore, the method includes controlling the disconnected network port to receive the new primary media stream and then outputting media data of the new primary media stream to the A/V device to be presented thereon.

摘要： The present aspects relate to techniques of timing synchronization of audio and video (AV) data in a network. In particular, the techniques for a AV master to distribute AV data encoded with one or more time markers to a plurality of processing nodes. The one or more time markers may be indexed to a precision time protocol (PTP) time stamp used as a time reference. In one technique, the nodes extract the time markers to determine an offset value that is applied to a PLL to synchronize AV data packets at a distribution node or a processing node. In another technique the distribution node or the processing node determines the worst case path, which corresponds to a system offset value. The distribution node then reports the system offset value to the AV master, which in turn adjusts the phase based on the report.

摘要： A system and method is provided for minimizing delay time for controlling media content capture during live video broadcast production. The system includes a video production receiver that receives media content streams from one or more cameras that includes live media content captured by the cameras and encoded in a first encoding format. Moreover, a multi-view interface displays the media content and a video production controller generates control instructions based on inputs to the interface to change operation of the cameras capturing the respective media content. A camera controller is included that transmits the generated control instructions to the cameras to change the operation for capturing the respective media content. Moreover, the video production controls production of a live video stream for video broadcast production using media content that is captured from the cameras and that is encoded in a second encoding format different than the first encoding format.

摘要： A media stream receiver is provided for scalable physical layer flow of packetized media streams. The media stream receiver replicates the processing block in time, rather than in hardware, through the use of a single shared memory and pointer alignment calculations, which combines multiple buffering stages as the single, shared memory buffer to offer redundancy and alignment, while acting as a receiver buffer to account for packet delay variations. By doing so the media stream receiver can perform a vertical interval switch between received media streams.

摘要： An image processor is provided for correcting brightness of saturated pixels of a captured image. The image processor can include a pixel saturation determiner that whether one or more pixels in an image sensor have been saturated by comparing pixel brightness levels of the pixels to a predetermined saturation threshold. Moreover, the image processor includes an image enhancer that generates a corrected image without artifacts due to the saturated pixel(s) by replacing the pixel brightness of the saturated pixel(s) with a pixel correction value that is based on a pixel brightness of one or more unsaturated pixel in the image sensor.
