In an embodiment, a data processing method comprises receiving, at a BIER replicator node that is programmed to implement Bit Index Explicit Replication (BIER) protocol, from a data source, a multicast stream packet identifying a service-level multicast group address; using the BIER replicator node, replicating the multicast stream packet according to BIER protocol and transmitting two or more replicated packet streams to two or more BIER receiver nodes that are programmed to implement BIER; using the two or more BIER receiver nodes, transmitting the two or more replicated packet streams to two or more receivers. Other embodiments may use modified iOAM (In-situ Operations, Administration, and Maintenance) techniques.

An electronic device, method, and a non-transitory computer-readable recording medium provide a function of locating and identifying a paired device in a wireless network. The wireless network communicatively connects a plurality of electronic devices including the electronic device and the paired device. The electronic device includes a user interface, a network interface, a hardware processor, and a non-transitory memory storing one or more programs. The hardware processor executes the programs to receive a search command using a first communication connection via the network interface. Moreover, the hardware processor executes the programs to determine whether the peer device identifying information matches identifying information of the electronic device. When the peer device identifying information matches the identifying information of the electronic device, the electronic device identifies as the paired device. Otherwise, the electronic device broadcasts to the wireless network using a second communication connection.

The data collection management device (10) is connected via a network to a plurality of communication devices (20) performing cyclic communication and includes: a network configuration storage (17) to store network configuration information indicating the communication devices participating in the cyclic communication; a data receiving unit (11) to receive communication data multicast from each communication device (20); a received data storage (12) to store the received communication data as collected data; a received data determination unit (13) to determine whether there is missing data in the collected data and identify unreceived communication data, based on information specifying communication cycles included in the collected data, on information specifying sender communication devices included in the collected data, and on network configuration information; and a retransmission requesting unit (15) to transmit a retransmission request of the unreceived communication data to one of the plurality of communication devices (20).

This technology enables prioritization of Multiple Stream Reservation Protocol (“MSRP”) transmissions in Audio Video Bridging (“AVB”) virtual local area networks (“VLANs”). An AVB switch receives a status from listener devices, associates a state with each of the statuses indicating whether each listener device is active or in-active, and stores each state in a database. For each listener device, a queue of MSRP protocol data unit (“PDU”) packets exists to be transmitted to the listener device. The AVB switch searches the database for listener devices with an active state, searches the queue for each active listener device for packets associated with an active state, and transmits the packets associated with the active state to each active listener device. Subsequently, the AVB switch searches each listener device's queue for packets associated with an in-active state and transmits the packets associated with an in-active state to each listener device.

The present disclosure relates to a video playback method and apparatus, a storage medium, and an electronic device. The method comprises: receiving a video playback request, the video playback request comprising first video information, and instructing to playback video data corresponding to the first video information by means of a target page; acquiring second video information corresponding to a video preview page, the video preview page being used to playback video data corresponding to the second video information; and when the first video information and the second video information are the same, performing video playback on the target page based on video playback progress information corresponding to the video preview page and video data loaded on the video preview page. Therefore, the transmission amount of video data can be effectively reduced, and the request response time of the video data and the waiting time of video playback can be shortened.

A command services manager of a control device can receive a command from a user interface device and provide for the storing and sharing of the command with one or more service providers so as to provide an improved user experience. Media service providers can register with a network resource associated with the command services manager. The command can be encrypted and stored locally at the control device or remotely at a network resource and be sent to a registered media service provider so that the media service provider can provide improved search responses and/or customize the interaction with the user, recommendation of content availability from other service providers, etc. The command services manager can also receive notifications from the media service provider and provide the notifications to the user, for example, notifications indicative of the success or failure of a command.

A split streaming system and method are provided in which a stream of data (that can be video, audio or textual data) is split and sent over a plurality of stream reflectors to a stream recipient. Each stream reflector performs time gradient replacement to manage the split streaming.

A transmission device according to an embodiment includes one or more processors. The processors divide a plurality of pieces of transmission data to be transmitted into first data and second data. The processors transmit the first data to a server device configured to distribute the transmission data to a reception device. The processors store the second data in storage. The processors receive, from the reception device or the server device, a request for transmission of the second data. The processors transmit the second data to the server device in accordance with the request for transmission.
