Srinath V. Ramaswamy has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10356492
    Abstract: The disclosure relates to a method of processing a sequence of image frames to reduce its length. One implementation may involve extracting coefficients (e.g., Discrete Cosine Transform coefficients) from components of individual frames, and comparing the resulting coefficients for sequential frames to identify frames having the least change from a prior frame. Also, scene change values for each frame may be calculated and placed in a sorted list to facilitate identification of frames for removal. Frame removal may be conducted in rounds, where a group of pictures (GOP) may only have one frame removed for any given round.
    Type: Grant

  • Publication number: 20190166170
    Abstract: The disclosure relates to a method of determining complexities and/or quality of video segments of a video program and providing data indicating the quality of video segments to user devices. Such data may be included in a manifest file of the video program. Based on the data indicating the complexities and/or quality of video segments, a user device or the system may choose a bitrate version for each video segment that minimizes network bandwidth usage while providing sufficient video quality.
