Abstract: A system for aggregating signals for sensors in a computer system is disclosed. Multiple aggregator circuits are coupled to corresponding sets of sensors. A particular client of multiple clients in the computer system may generate a request for a particular sensor and send the request to an aggregation processor coupled to multiple clients. The aggregation processor can relay the request to a particular aggregator circuit coupled to the particular sensor. Upon receiving the request, the particular aggregator circuit may relay the request to the particular sensor.

Abstract: A video delivery system generates and stores reduced bandwidth videos from source video. The system may include a track generator that executes functionality of application(s) to be used at sink devices, in which the track generator generates tracks from execution of the application(s) on source video and generates tracks having a reduced data size as compared to the source video. The track generator may execute a first instance of application functionality on the source video, which identifies region(s) of interest from the source video. The track generator further may downsample the source video according to downsampling parameters, and execute a second instance of application functionality on the downsampled video. The track generator may determine, from a comparison of outputs from the first and second instances of the application, whether the output from the second instance of application functionality is within an error tolerance of the output from the first instance of application functionality. If so, the track generator may generate a track from the downsampled video. In this manner, the system generates tracks that enable reliable application operation when processed by sink devices but also have reduced size as compared to source video.
