Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for reducing processor latency through the use of dedicated cores. In one aspect, a method includes a multi-core processor having n cores, including, selecting k cores of the n cores of the multi-core processor to perform dedicated low-latency operations for the n-core processor, where k is less than n, m cores are unselected, and each core of the multi-core processor has a rated core capacity. The methods operate the selected k cores at less than the rated core capacity such that k cores are collectively underutilized by an underutilized capacity and operate one or more of the m cores at a capacity in excess of the rated core capacity such that the m cores operate at a collective capacity that exceeds a collective capacity of the rated core capacities of the m cores.

Title: Detecting sentinel frames in video delivery using a pattern analysis
Inventor: STEPHEN P EMEOTT
IPC: G06K9/00
Filed: 2017-05-11
Abstract: Particular embodiments extract features for frames from a video. Then, a sequence of frames is identified based on a pattern analysis of frames based on the features. This pattern may be used to select sentinel features from the sequence of frames. For example, a pattern may include a first sentinel sequence followed by a transitional frame and then a second sentinel sequence. The transitional frame may be a black frame that is used to identify back-to-back sentinel sequences. Then, a sentinel frame that demarks a transition from a first content type to a second content type is identified. For example, the frames on either side of the black frame may be very similar and be identified as sentinel frames that mark a transition from program content to advertisement content. The above process may allow automated detection of sentinel frames that can run without user supervision.
