  • Publication number: 20230396355
    Abstract: Methods, systems, and devices for wireless communications are described. A rateless code may be used to generate n encoded packets based on a set of source packets. A modulation technique may be used to generate first symbol packets from the encoded packets. And a layered modulation technique may be used to generate coded symbol packets from the first symbol packets. The layered modulation technique may include generating a coded symbol packet from a group of first symbol packets. Different weights may be applied to the different first symbol packets included in the group of first symbol packets before the first symbol packets in the group are combined together. A receiving device may demodulate the transmitted coded symbol packets to reconstruct the group of first symbol packets, use the reconstructed group of first symbol packets to recover the encoded packets, and use the encoded packets to reconstruct the source packets.

  • Publication number: 20230396819
    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.
