  • Patent number: 11550713
    Abstract: Systems and methods are described for enabling garbage collection on data storage systems. Traditional garbage collection often attempts to track use of data items on an individual level, deleting each item when it is no longer used. In distributed systems, tracking use on an individual level is difficult, and may require centralized knowledge across the system with respect to individual data items. Provided herein is a “coarse-grained” garbage collection mechanism, which divides objects into logical groups referred to as “roots.” Each root has a life cycle. While active, new data can be stored in a root. While inactive, use of data within a root can cause that date to be copied to a different, active root. When the system detects that data hasn't been used in an inactive root for a threshold period, the root can be considered “dead” and data within the root may be deleted.

  • Publication number: 20070110168
    Abstract: A method for generating low delay video streaming is provided. In an embodiment, the bit rate desired for outputting the received video stream is input into a buffer (32 of FIG. 1), determining the size of the buffer according to the bit rate, outputting the video frame (36 of FIG. 1) according to the bit rate and the buffer size by varying the bit rate accordingly to obtain the level of quality and delay period required. Additionally, a header may be assigned to each frame and the sleep time for each frame is allocated prior to the time for frame compression.
