  • Patent number: 10498794
    Abstract: Embodiments of the present invention are directed to a social entertainment platform that supports live social video streaming and messaging. One common use for this social entertainment platform is to allow audience members to watch and interact with a person playing an electronic game. The social entertainment platform allows a streamer to stream live (in substantially real-time) on a network(s), such as the Internet, for a live audience to view and to respond to the live entertainment. The social entertainment platform includes several unique areas, including a real-time broadcasting component, a real-time messaging component, and an integrated user interface (UI) component, that make the social entertainment platform advantageous to use over traditional platforms.

  • Patent number: 6353604
    Abstract: A bidirectional digital data communication system which generate phase coherent upstream clock and carrier signals from recovered downstream clock generated from a master clock in a central unit. The preferred species uses any downstream clock rate and generates a phase coherent upstream clock so long as the two clock rates can be related by the ratio M/N where M and N are integers. One embodiment uses an MCNS downstream and an SCDMA upstream and uses MNCN timestamp messages in the downstream to achieve an estimate of RU frame offset prior to establishing frame alignment using a ranging process. The use of timestamp messages to estimate the offset is aided by a low jitter method for inserting timestamp messages by avoiding straddling of MPEG packet headers with the sync message. Clock slip is detected by counting upstream clock cycles over a predetermined downstream clock interval and the RU transmitter is shut down if slip is detected to prevent ISI interference from misaligned codes.
