  • Patent number: 11856191
    Abstract: A post processing system, method and computer program product content-adaptively transforms MPEG on-demand media streams, including a video optimizer software development kit (SDK); an application layer controlling the SDK interfacing with a mobile device operating and file system. Raw pixel frame buffers are parsed and structured. The buffers are normalizes for processing. Source content is analyzed in an uncompressed format for video patterns and characteristics and parameters are selected in a video codec output format. Estimated are parameters for portions and/or segments of the content. The content is recompressed and optimized in a content-adaptive manner to generate optimized content written into persistent storage of the mobile device, and segments of which are combined with an audio stream and/or a metadata stream information to generate a playable media stream in an ISO base media file format and/or a media file application specific format.

  • Publication number: 20160162613
    Abstract: A standard acquisition system is selected, the system comprises seismic signal sources disposed on an excitation surface and seismic signal receivers disposed on an acquisition surface, then a fold number is specified. A bin size is selected for a reflecting boundary, and the reflecting boundary is broken down into bins with the selected size. Ray tracing from each seismic signal source to each bin at the reflecting boundary and elongating of a reflected ray from the reflecting boundary to the acquisition surface are performed by computer simulation. A density of the seismic receivers location at the acquisition surface is calculated using a computer program. Then, based on the calculated seismic receivers location density, the seismic receivers are disposed at the acquisition surface for the selected seismic acquisition system providing the specified fold number.
