  • Patent number: 10686853
    Abstract: Online content is served to participant devices using two or more systems. The content served by each system is not the same. Rather, the content streams coming from each system is a partial or lower-quality version of the original high-quality version of the content stream. A single one of the partial data streams can be used by the participant device to output a lower-quality version of the original content stream to the user. Alternately, the received partial content streams can be combined to output, to the user, a high-quality version of the original content stream.

  • Publication number: 20200162438
    Abstract: A method and apparatus for encrypting communications between two radio frequency (RF) transceivers selects a level of encryption based on device characteristics of the two RF transceivers. Each RF transceiver generates a common sequence having an integer, M, symbols based on the selected encryption level and on signals received from the other RF transceiver. Each RF transceiver then generates a cryptographic key based upon the common sequence, encrypts a message using the cryptographic key, and sends the encrypted message to the other RF transceiver. In one embodiment, the M symbols are selected from an alphabet where the value M and the size of the alphabet are selected based on the device characteristics of the two RF transceivers.

  • Patent number: 10432355
    Abstract: Techniques for enhanced error protection for high priority communication sessions are described. Generally, the described techniques enhance error protection for high priority communication sessions, such as emergency calling, such that the high priority communication sessions are essentially error free. According to various implementations, user input to initiate a communication session over a network is received at a communication application. In response to detecting that the communication session corresponds to a high priority communication session, error protection for data of the high priority communication session is enhanced. The data may be enhanced in a variety of different ways, such as by performing forward error correction on the data. The enhanced data of the high priority communication session is then communicated over the network to an endpoint.

  • Publication number: 20190253561
    Abstract: An initial data center can be selected to host a communication session between multiple participants. This data center can be initially selected based, at least in part, on a first set of effective distances (e.g., representing distances between the initial data center and the first group of participants modified by effective distance factors). For example, the data center closest to the centroid can be selected. The effective distance factor (or weighting) can be based on one or more of the participant's device/driver type, the participant's network type, the participant's connection type, and a participant weighting factor. Then, as the multiple participants on the conference session change or the effective distances change (e.g., based on a change in connectivity), a second data center can be selected to host the communication session.

  • Publication number: 20190245899
    Abstract: One or more data centers are selected to host an online conference. The selection of the data center is based on a set of metrics that are measured from ‘synthetic’ transactions. These synthetic transactions are sent between candidate data centers and the participants in the conference call in order to measure one or more performance metrics (e.g., link quality metrics such as delay, packet loss, etc.) These measured performance metrics are used to determine a centroid that represents the geometric center or ‘center of mass,’ of the link quality between participants and data centers. This ‘link quality centroid’ is used to select a subset of data centers as candidate data centers. The candidate data center with the best average performance metric(s) is selected as the data center to host the conference.
