A system for transmitting information may include a server that generates pseudo-random superpositions, each superposition including multiple packet fragments encoded using a Galois field. The system may transmit the superpositions across a plurality of communication links, which form a single logical path, to a client device. Communication links may include a combination of diverse communication channels, and more preferably one or more low latency (but low bandwidth) communication links and one or more high bandwidth (but high latency) communication links. Advantageously, the use of a plurality of communication links may facilitate transmitting information quickly and reliably.

Devices, methods, and/or systems for broadcasting in a wireless local area network (WLAN). A STA receives a frame from a wireless access point (AP) which includes an indication that an enhanced broadcast service (eBCS) service is ending. The frame may include an end-of-broadcast-service announcement information element, and/or an indication of a time at which the eBCS service is ending. The STA may negotiate with the AP for continuation of the broadcast service if the STA desires to continue receiving the eBCS service beyond the time at which the eBCS service ends. The STA may receive a trigger frame from the AP which triggers a response from the STA indicating that it desires to continue receiving the eBCS service beyond the time at which the eBCS service ends.

Some examples relate to selection of a rendezvous point in an IP multicast network managing multicast group traffic. An example includes transmitting, from a controller in a cloud computing system, messages to a source device and a host device in an IP multicast-capable network, which may include two peer network devices that are virtualized to function as one virtual device. Based on the response to the messages, the controller may determine that the source device is present in OSI layer 3 and the host device is present in OSI layer 2. The controller may determine that the peer network are located downstream in relation to the determined layer of the source device. The controller may select a non-peer network device as a rendezvous point in the IP multicast-capable network. Further to the selection, the controller may synchronize an active-active configuration between the peer network devices.

A system for generating and applying a secure token in a resource distribution network is provided. For example, a headend system generates a global token based on a time duration specified for multiple meters that are in communication with the headend system through at least a mesh network in a normal condition. The global token is associated with the time duration and is applicable to the multiple meters. The headend system causes the global token to be broadcast via a broadcast network. After receiving the global token, the meter verifies the global token and determines the time duration associated with the global token. The meter further connects premises associated with the meter to a resource distribution network for at least the time duration associated with the global token.

A method of transmitting a broadcast signal, includes processing one or more input packets to generate one or more link layer packets, a link layer packet including a header and a payload, the header including packet type information representing a type of an input packet in the payload and payload configuration information representing a configuration of the payload, the payload configuration information representing whether the link layer packet carries a single input packet or not, wherein the type of the input packet is either an Internet Protocol (IP) packet or a Movie Picture Exports Group (MPEG) Transport Stream (TS) packet, the payload configuration information is set to 0 (zero) in response to a layer packet including a single input packet, and 1 in response to a link layer packet including more than one input packet or a segmented part of one input packet, in response to the link layer packet including the single input packet, the header includes header mode information, the header mode information is set to 0 (zero) in response to a payload length that is less than 2048 bytes, 1 in response to a payload length that is larger than 2047 bytes; processing the one or more link layer packets to generate the broadcast signal; and transmitting the broadcast signal.

A conferencing system terminal device includes a display, an audio output, a user interface, a communication device, and one or more processors. The one or more processors present an audio difficulties user actuation target upon the display during an audio or video conference occurring across a network and concurrently with a presentation of conference content. Actuation of the audio difficulties user actuation target indicates that audio content associated with the audio or video conference being delivered by the audio output is impaired.

Advertisement systems may have an administration server, a broadcast system, a receiver, and a consumer device. The receiver may be configured to receive an advertisement with a call-to-action code. The receiver may also be configured to broadcast the advertisement with the call-to-action code to a consumer. The receiver may have an input mechanism. The consumer device may be in communication with the receiver and the administration server. The consumer device may be configured to receive the call-to-action code from the receiver when the consumer engages the input mechanism. The consumer device may include a software application. The software application may be configured to parse the call-to-action code with the administration server into call-to-action instructions. The software application may be further configured to permit the consumer to selectively integrate the call-to-action details into a third-party application on the consumer device.

A computer system that processes state messages is described. During operation, the computer system may receive, associated with communication network devices in a network, the state messages, where the state messages include report messages and event messages. Then, the computer system may validate the state messages based at least in part on tokens associated with the state messages. Moreover, the computer system may provide the report messages to one or more first consumers in the computer system. Furthermore, the computer system may select a subset of the event messages based at least in part on a type of event. Next, the computer system may translate the selected subset of the event messages from a first format to a second format. Additionally, the computer system may provide the translated subset of the event messages to one or more second consumers.

A method for securely broadcasting information to a group of undisclosed recipients. The information in an information system is encoded by applying a hash function to a group of messages to form the information stream, wherein portions of the information in the information stream are intended for respective ones of the group of undisclosed recipients. The information is encoded such that that only an intended recipient can decode a portion of the information intended for the intended recipient. The information stream is broadcasted to the group of undisclosed recipients.

Delivery mode switching between unicast and multicast/broadcast is described. A WTRU may move from a RAN node that supports multimedia broadcast/multicast service (MBMS) session to one that does not support MBMS session, or vice versa. In order to avoid duplicated packet transmission, the unicast delivery mode may be deactivated when the WTRU decides to use multi-cast/broadcast session. When the multicast/broadcast session is not available, the WTRU may re-activate the unicast delivery mode for MBMS. For example, the PDU session for unicast delivery mode deactivation may be released and the PDU session for unicast delivery mode reactivation may be re-established. Such activity may necessitate additional signaling between WTRU and the network for PDU session establishment/release and all other services running in the PDU session may be interrupted.
