Real-time latency measurement of video streams

Frames of a video stream collected at first and second points along a video delivery chain are buffered into first and second buffers, respectively, the second point being downstream the video delivery chain from the first point. A control group is identified as a subset of frames of the second buffer. Correlations of extracted features of the control group to extracted features of successive windows of frames of the first buffer are computed, the extracted features being based on spatial information and temporal information of the video stream. A delay between the video stream collected at the first point and the video stream collected at the second point is identified according to a maximum correlation of the correlations.

Embodiments include processes for media object rendering, including the steps of providing a plurality of clients, the clients including a media client and the clients in communication with a synchronization client, the clients defining a synchronization group. The media clients include instructions for receiving media object content over a network from a content server, rendering the media object content, and random access to the media object content in response to synchronization client seek time instructions. The synchronization client includes instructions to calculate a relative lag and provide seek time instructions to the media clients for a media object being rendered, the relative lag being a running measurement of its offset relative to the synchronization server's clock. The synchronization client periodically queries the clock of a synchronization server. The synchronization server responds to the synchronization client queries with internal clock value as a timestamp and a timestamp for a target time reference within said media object content for the synchronization group, whereby the synchronization client provides seek time to its paired media clients for the media client to move to that offset, establishing and maintaining playback synchronization among the synchronization group.
