Assignee:

Avid Technology, Inc. - Erlington MA

International Classification:

G06F 15/16

US Classification:

709203, 709215, 709244, 711 5, 711 11, 711113, 711114, 711162, 710 68

Abstract:

In one general aspect, a data access method is disclosed that includes directing data block write requests from different clients to different data storage servers based on a map. Data blocks referenced in the data block write requests are stored in the data storage servers. Data from the data write requests are also relayed to a parity server, and parity information is derived and stored for the blocks. This method can reduce the need for inter-server communication, and can be scaled across an arbitrary number of servers. It can also employ parity load distribution to improve the performance of file transfers.

Abstract:

Video processing methods include correlating a video frame in a video stream with event data in a data stream based on a video frame time stamp and an event data time stamp, the time stamps being based on a time scale that is independent, and recording the correlation in a database. Other video processing methods include receiving a query for a video frame and searching for event data in a database. The database has an event data table and a video data table used in locating the video frame. Further video processing methods include receiving a query to retrieve a video clip for each of a plurality of plays, searching for event data in a database, locating the video clip for each of the plurality of plays, and compiling the video clips into a compiled video stream lacking video frames that do not satisfy the query.
