  • Publication number: 20220182692
    Abstract: A computing system that identifies a media stream that a media client is processing for presentation determines which frame format of the media stream the media client is processing for presentation. And the computing system uses that determined frame format as a basis to facilitate dynamic content modification. For instance, based on then determined frame format, the computing system could work to ensure that replacement or overlay content that the media client obtains to facilitate dynamic content modification of the media stream is of that determined frame format. Further or alternatively, based on the determined frame format, the computing system could work to ensure that the media client gets provisioned with reference fingerprints of that particular frame format of the media stream, for use to facilitate client-side fingerprint matching to confirm that the media stream continues to be identified media stream.

  • Patent number: RE49158
    Abstract: The present invention relates a method and apparatus for transmitting/receiving data using multiple codewords in a communication system using SC-FDMA (single carrier frequency division multiple access). A transmitter generates the multiple codewords for user data and transmits the generated multiple codewords. A receiver receives the multiple codewords and sequentially performs decoding and SIC (successive interference cancellation) on the received multiple codewords. Therefore, this structure can minimize a PAPR (peak to average power ratio) and considerably reduces interference between symbols in a frequency selective fading environment.
