  • Patent number: 11470374
    Abstract: Systems, methods, and devices enable a receiver device to determine completeness of low level signaling (LLS) tables received via broadcast transmissions. In various embodiments, broadcast service signaling may include determining whether a received LLS table is a directory table identifying each of a complete set of LLS tables, parsing the directory table, determining whether the directory table is confirmed based at least in part on a digital signature in the directory table, determining whether a complete set of LLS tables is received based at least in part on the identification of each of the complete set of LLS tables in the directory table, and determining available services based at least in part on the complete set of LLS tables before an expiration a repetition time period after receiving the directory table.

  • Patent number: 11310540
    Abstract: In one example, a device includes one or more processors implemented in circuitry and configured to execute a Dynamic Adaptive Streaming over HTTP (DASH) aware application (DAA) and a DASH client, and one or more user interfaces. The DAA subscribes to DASH events of a DASH event stream via a first application programming interface (API) between the DAA and a DASH client executed by the one or more processors. The DAA then receives data for one or more DASH events of the DASH event stream from the DASH client via a second API between the DAA and the DASH client, the data for the one or more DASH events specifying interactivity-related content. The DAA then presents the interactivity-related content via the one or more user interfaces. The DAA may further send usage measurements on usage of the interactivity-related content to the DASH client, for reporting to a report server device.

  • Publication number: 20190306199
    Abstract: A method for securely connecting to a remote server that provides improved Internet security. In the method, a client receives a request to connect to a remote server associated with a domain name. The client, when resolving the domain name, determines whether the remote server supports at least one predetermined IP layer security protocol. The client performs a key exchange protocol with the remote server to generate at least one shared secret in response to determining that the remote server supports the at least one predetermined IP layer security protocol. The client connects to the remote server using the at least one shared secret in the IP layer security protocol.
