Abstract: A method and system are described wherein a terminal sends, to a server, a video request message that includes an identifier of a virtual reality (VR) video. The VR video comprises N sub-bitstreams. The terminal receives a video response message sent by the server. The video response message indicates multicast addresses respectively corresponding to the N sub-bitstreams, and the terminal determines a target sub-bitstream based on a current field of view of a user, and obtains the target sub-bitstream based on a multicast address corresponding to the target sub-bitstream. The multicast address is one of the multicast addresses, and the target sub-bitstream comprises at least one sub-bitstream of the N sub-bitstreams.

Abstract: Apparatuses, components, devices, methods, and systems for tourniquets are provided. An example tourniquet includes a tensioning device having a housing and a pull-cord assembly and a strap that passes through the housing. An example strap has a first end and a second end. The example strap is arranged to together with the housing form a loop for encircling a limb. An example pull-cord assembly is configured to advance the strap through the housing to tighten the loop.

Abstract: A process for requesting information, the process including generating a plurality of range requests using a client having a plurality of network interfaces, the range requests each corresponding to a data range of a data resource, transmitting, from the client having the plurality of network interfaces, a plurality of range requests to a server via the plurality of network interfaces, receiving, at the client and from the server, a plurality of segments via the plurality of network interfaces such that each segment is received via a network interface which transmitted the corresponding range request, each segment including a portion of the data resource, and reassembling the data resource using the plurality of segments.
