A media processing apparatus according to embodiments comprises: a memory; and a processor connected to the memory, wherein the processor may be configured to receive media on the basis of a session comprising multicast and unicast, receive multicast server configuration information for the media, receive multicast gateway configuration information for the media, and control the media. A media processing method according to embodiments may comprise the steps of: receiving media on the basis of a session comprising multicast and unicast; receiving multicast server configuration information for the media; receiving multicast gateway configuration information about the media; and controlling the media.

An information processing method, an interconnection device, and a computer-readable storage medium are provided. The interconnection device includes a request processing module configured for: receiving a data access request from at least one processor, wherein the data access request comprises a merge bit, a multicast group identifier (MGID), and a multicast transaction identifier (MTID); determining whether the data access request is a multicast request; determining whether the interconnection device receives other multicast requests if it is determined that the data access request is a multicast request based on the MGID, the MTID, and a static routing policy of a multicast group; and obtaining the other multicast requests if it is determined that the interconnection device receives the other multicast requests, merging the multicast request with the other multicast requests into a merged request, and forwarding the merged request to a next-hop device of the interconnection device.

An apparatus and a method for providing information used for generating and consuming multimedia content in a broadcast system supporting a multimedia service based on an Internet protocol are provided. The method includes composing a message type field containing information indicating on a type of control information contained in the control message, composing a length field containing information on the length of the control message, composing optional fields having different values according to the type of the control information, and composing a payload field containing content of the control information.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit an indication of one or more beams for simultaneous unicast and multicast monitoring and receive, using the one or more beams, at least one of unicast traffic or multicast traffic. Numerous other aspects are provided.

A multicast data packet processing method in a point-to-multipoint (P2MP)-based bit index explicit replication (BIER) multicast tree, which includes an intermediate node configured to use P2MP to forward a BIER packet, includes receiving a first multicast data packet with a BIER header having a first label. The method further includes obtaining a first forwarding entry based on the first label. The first forwarding entry includes the first label, a first identifier identifying the multicast tree, and a second identifier instructing to perform P2MP forwarding. The method further includes obtaining, based on the first identifier, a second forwarding entry including the first identifier and a second label. The method further includes obtaining a second multicast data packet based on the second identifier, the second forwarding entry, and the first multicast data packet, and sending the second multicast data packet. The second multicast data packet includes the second label.

The present invention relates to systems and methods suitable for verifying and compensating nodes for streaming multimedia. In particular, the present invention relates to systems and methods that utilize a blockchain to verify and compensate devices for computational resources contributions when streaming multimedia over a decentralized network.

Some embodiments of the invention provide novel methods for providing transparent services for multicast data messages traversing a network edge device operating at a boundary between two networks. The method analyzes data messages received at the network edge device to determine whether they require a service provided at the boundary and whether they are unicast or multicast (including broadcast). The method modifies a multicast destination media access control (MAC) address of a multicast data message requiring a service to be a unicast destination MAC address and provides, without processing by a standard routing function, the modified data message directly to an interface associated with a service node that provides the particular service required by the data message. The method receives the serviced data message, restores the multicast destination MAC address, and forwards the serviced data message to a set of destinations associated with the multicast destination address.

An apparatus for receiving a broadcast signal, includes a receiver configured to receive the broadcast signal, a parser configured to parse signaling information for a service scan included in the broadcast signal, a link layer processor configured to process a link layer packet included in the broadcast signal, and an audio/video (A/V) processor configured to present broadcast contents based on the signaling information for the service scan and the link layer packet.

A hub includes: a multi-function control unit; a microprocessor; at least one sharing port connected to the multi-function control unit, which controls the at least one sharing port to connect with a computing device; a USB audio control unit connected to the multi-function control unit; an audio processing module connected to the USB audio control unit and the microprocessor; a wireless module connected to the audio processing module and the microprocessor and used for wireless communication with a mobile device; and an audio input and output module connected to the audio processing module and the microprocessor, and including an audio cable jack used for connecting with an audio input and output device, and/or a built-in speaker and a microphone.
