A method of generating a stereoscopic panorama is provided, the method comprising: processing a first right image, a second right image, a first left image, and a second left image to derive a right homography between the first right image and the second right image and a left homography between the first left image and the second left image; stitching the first right image with the second right image to generate a right panorama, the first left image with the second left image to generate a left panorama wherein the right homography is consistent with the left homography; and generating a stereo panorama using the right panorama and the left panorama. The method further comprises capturing the first right image, the second right image, the first left image, and the second left image using a camera array comprising a first right camera, a second right camera, a first left camera, and a second left camera, wherein a relative position between the first right camera and the second right camera is substantially the same as a relative position between the first left camera and the second left camera, and the first right camera and the second right camera comprise parallel optical axes.

One embodiment of the invention sets forth a mechanism for encoding video streams associated with the same digital content such that switch points staggered across two video streams occur at every offset temporal distance The offset temporal distance is less than the distance between two consecutive key frames in a given video stream This enables a content player to switch to a video stream having a playback quality up or down one level from a current video stream at the offset temporal distance from the most recently played key frame In effect, the content player does not wait the entire key frame temporal distance before switching

The invention discloses a data synchronization method and a data synchronization device. The method comprises the steps of obtaining at least two paths of video streams from different collection devices located on the same main body, wherein the video streams comprise target video clips when the same state of the main body of the acquisition equipment changes; then determining synchronous compensation values of at least two paths of video streams according to the target video clips; then determining to-be-synchronized video clips in the at least two paths of video streams, and performing synchronous compensation on the to-be-synchronized video clips according to the synchronous compensation values. The synchronization compensation value of the video stream is determined according to the target video clip corresponding to the main body state change, and then the to-be-synchronized video clip is subjected to synchronization compensation according to the synchronization compensation value, so that the synchronization of each video stream can be dynamically balanced, and the synchronization error caused by transmission can be reduced or eliminated; and the method is realized without atimestamp, so that high-precision synchronous transmission can be realized with relatively low cost.

The invention discloses video recording equipment with a standard definition video depth detection function. The equipment comprises a standard-definition video decoding chip and an FPGA chip. The standard-definition video decoding chip is used for converting input standard-definition videos of different formats into digital videos of a unified data format and sending the digital videos to the FPGA chip, and meanwhile a field synchronization locking state, a color carrier frequency locking state and a field frequency state are written into a register. The FPGA chip is used for firstly detecting whether effective digital video input exists or not. If yes, the field synchronization locking state, the color carrier frequency locking state and the field frequency state are read from a registerof the standard definition video decoding chip, and the original format of the digital video is judged. The video recording equipment provided by the invention can carry out deep detection on the standard definition video input into the aviation record loader, accurately judges the type of the standard definition video, and improves the testability and maintainability of the aviation record loader.

A sharing client device shares content with viewing client devices. A sharing module operating on a sharing client device and on the viewing client devices facilitates the creation and analysis of viewer snapshots, permitting automatic determination of whether viewers are up-to-date with their display of shared content. Based on the analysis and on a policy of the sharing module, the sharing module can take a number of actions, such as generating and displaying a viewer summary that a user of the sharing client device may view to determine whether, or to what extent, the viewing client devices are up-to-date in their displays of the shared content.

Dynamic user interface and module facilitating content sharing in a distributed computing environment

A system for video synchronization between multiple video streams and methods for making and using same. The video synchronization system can synchronize video frames of a search frame sequence with respect to a reference frame sequence, ordering frames of the search frame sequence so that image data of the search frame sequence corresponds to image data of the reference frame sequence. Video synchronization can be performed for video streams that originate from a single imaging device or multiple imaging devices. Comparison of the search frame sequence to the reference sequence can be performed using point sequences in the image data. The points of the point sequences can be individual pixels or features having one or more pixels. Video synchronization can be performed by maximizing a correlation, between corresponding image data. The systems and methods are advantageously suitable for synchronizing videos taken from mobile platforms such as unmanned aerial vehicles.
