A data communication method and a related apparatus are provided, and the data communication method includes: constructing, by an access device, a beacon frame, where the beacon frame includes a newly added field, and the newly added field represents multiple data guard interval lengths supported by the access device; and broadcasting, by the access device, the beacon frame, so that a terminal selects an available guard interval length matching a data guard interval length supported by the terminal from the beacon frame, and performs data communication with the access device by using the available guard interval length. By using the present invention, data communication between the access device and the terminal can be implemented when the access device supports multiple data guard interval lengths.

An apparatus for monitoring a multicast group is provided. The apparatus includes a storage, a receiver and an operation processor. The storage is configured to store first data including a first authenticated message authenticated as being published by a publisher of the multicast group to n-th data including an n-th authenticated message authenticated as being published by the publisher where n is a natural number of 2 or more. The receiver is configured to receive status data including a first propagation message to be delivered to the multicast group. Further, the operation processor is configured to generate monitoring information including status information of the multicast group by using the status data and the first to n-th data.

Systems and methods for providing synchronous transmission of streaming media are disclosed. One method may include: receiving, from a first user device associated with a first user, a request to invite a second user to a virtual media streaming session; retrieving, from the at least one database, a second user profile, the second user profile identifying a second user device associated with the second user; transmitting, subsequent to the retrieving, instructions to the second user device to present a notification alerting the second user of the request; determining, using a processor, whether a response accepting the request is detected from the second user device; and connecting, responsive to determining that the response accepting the request was detected, the second user profile to the virtual media streaming session; wherein multimedia content presented in the virtual media streaming session is simultaneously viewable on the first user device and the second user device.

A method, a system, and a computer program product for determining whether signals are received by one or more devices in a virtual meeting. The method includes transmitting a data stream received from one or more host computing devices to one or more user computing devices in a plurality of user computing devices. The host and user computing devices are communicatively coupled using a real-time online connection. A first hash in a plurality of hashes is generated by the server using a portion of the data stream and stored in a memory location. The first hash is compared to a second hash received from the user computing devices. The second hash is generated by the user computing devices upon receipt of the transmitted data stream. Based on the comparison, a status of the real-time online connection between the host computing devices and the user computing devices is determined.

A trust network is formed in a communal media system connected to a streaming application and executed within the streaming application. Source location is received for multimedia content selected in the streaming application and transmitted to user devices participating in a communal session. During the communal session, offerings are presented to the user devices in the communal session and user data associated with user interactions with the offerings are obtained and analyzed. Information presented to the user devices in the communal session is optimized based on the user data. Delivery of the multimedia content and social media content generated on the user devices is synchronized. The multimedia content and the social media content are delivered to the user devices at the same time, without any noticeable lag time during receipt of the multimedia content and the social media content by the user devices.
