Abstract: Systems and methods for improving the performance and reliability of a copy manager by dynamically controlling performance of concurrent extended copy tasks. In one embodiment, the number of concurrent extended copy commands which are allowed to be active within a copy manager are dynamically adjusted based upon the resources available to service the commands (e.g., buffers available to store in-transit data). For example, the total number of data buffers, together with the number of buffers required to execute a single extended copy command, may be used to constrain the number of concurrent extended copy commands which are allowed to be active in the copy manager. Extended copy commands which are not active are held in queue for later execution.

Abstract: A method of processing video information includes scaling the video information using a first number of fields if a field indicator indicates the first number of fields and scaling the video information using a second number of fields if the field indicator indicates the second number of fields. The video information is searched for motion. The field indicator is set to indicate the first number of fields if the video information includes a first amount of motion, and the field indicator is set to indicate the second number of fields if the video information includes a second amount of motion.
