Abstract: A video playing method, a device, and a system are provided. The method includes: receiving, by a VR device, a first-resolution VR video stream of a first viewing angle and a second-resolution VR video stream of a full viewing angle that are sent by a server, where the first resolution is greater than the second resolution; playing an image of the first viewing angle by using the VR video stream of the first viewing angle; when determining that the viewing angle changes, playing an image of a current viewing angle by using the first or both of the VR video stream of the full viewing angle and the VR video stream of the first viewing angle; sending, to the server, viewing angle information that carries a parameter for indicating a changed-to second viewing angle; receiving a first-resolution VR video stream of the second viewing angle sent by the server.

Abstract: The objective of the embodiments of the present invention is to provide a method and an apparatus of sending address correspondence information and updating a MAC table in a data link layer protocol of applying Link State Routing for solving the problem that too much bandwidth is occupied by broadcasting address correspondence information solicitation in a data link layer of applying link state routing. Through adopting the technical solution of the embodiments of the present invention, since besides the ingress network node, other network nodes also store address correspondence information in their address correspondence information tables, so when they receive an address correspondence information solicitation, they can directly reply with an address correspondence information response without broadcasting the solicitation, decreasing the bandwidth occupied by broadcasting address correspondence information solicitation in a data link layer of applying link state routing.
Abstract translation: 本发明的实施例的目的是提供一种发送地址对应信息并更新在应用链路状态路由的数据链路层协议中的MAC表的方法和装置，以解决广播占用太多带宽的问题 应用链路状态路由的数据链路层中的地址对应信息请求。 通过采用本发明的实施例的技术方案，除了进入网络节点之外，其他网络节点还在其地址对应信息表中存储地址对应信息，所以当他们收到地址对应信息请求时，可以直接回复 地址对应信息响应而不广播请求，减少在应用链路状态路由的数据链路层中广播地址对应信息请求占用的带宽。

Abstract: The present disclosure relates to the field of optical communications. A board is disclosed. The board includes a level adjustment circuit, a detection apparatus, and a control apparatus. The detection apparatus is configured to: when the detection apparatus is connected to an optical module, receive an indication signal output by an upstream optical signal detection pin; continuously detect a received first level signal and the received indication signal. If there is a second level signal, opposite to the first level signal, the detection apparatus notifies the control apparatus that the optical module is inserted. If there is no second level signal in the signal received within the preset duration, the detection apparatus notifies the control apparatus that the optical module is absent. This makes the optical module less dependent on the in-position pin, and decreases a quantity of pins of the optical module.
