A system and method for managing video storage in a network including continuously receiving in real time, at a recording server, from an edge device having a local storage, a plurality of incoming packets pertaining to a video stream, determining that at least one packet of the video stream is missing, and retrieving from the edge device the missing packets stored in the local storage, while continuing receiving additional incoming packets pertaining to the video stream in real time.

Method and apparatus for managing video storage

A method, apparatus and a computer readable medium for skipping macro blocks of a compressed video. The method includes, for at least one INTER frame, saving a set of macro blocks including at least one of a macro block having a motion vector greater than a predetermined motion vector threshold, a macro block having positional correspondence to at least one macro block having a motion vector, a macro block having a size greater than a predetermined macro block size threshold, and a macro block having positional correspondence to a second macro block in a previous group of pictures, the second macro block having a motion vector. The method deletes and marks as skipped one or more remaining macro blocks, and merges the set in an order to create a compressed frame including a skipped macro block. The processor implements the method, and the computer readable medium contains processor instructions.

System and method for enhancing compression using skip macro block on a compressed video

The subject matter discloses a method, comprising obtaining a current retention time of storage associated with a digital recorder; obtaining current bitrates of channels used to transmit video captured by edge devices communicating with the digital recorder. The method then determines change in compression rates to be allocated to at least a portion of the channels according to the current retention time and the current bitrates and transmits the change in compression rates to be allocated to the channels to edge devices communicating with the digital recorder. The method can be implemented in a system in which several digital recorders use the same storage.

Method and system for utilizing storage in network video recorders

Embodiments of the invention are directed to a system and method for controlling visual parameters of a capturing device to minimize clipping and saturation according to predefined parameters. The method may include processing pixel values of a current input frame of a received video signal captured by a capturing device; accumulating processing results of the current input frame to processing results of one or more previous input frames and calculating a desired dynamic range based on pre-determined user parameters. The processing may further include checking if the accumulated results are within the desired dynamic range and determining if adjustment is desired. If the accumulated results are not within the desired dynamic range, adjusting visual parameters for a subsequent input frame, by controlling the capturing device and if the accumulated results are within the desired dynamic range maintaining current visual parameters of the current input frame for the subsequent input frame.
