Abstract: A video media playing method includes: A media server receives a call request message from originating UE, where the call request message includes first session description protocol (SDP) information of the originating UE; the media server receives a first response message returned by terminating user equipment (UE); the media server determines, based on the first response message, that the terminating UE does not support a resource reservation mechanism/procedure; the media server sends a second response message to the originating UE, where the second response message includes second SDP information used to respond to the first SDP information; and the media server performs video media negotiation with the originating UE through the resource reservation mechanism/procedure.

Abstract: This application discloses a detection apparatus, a shunt circuit, and a terminal device. The detection apparatus may include a detection unit, an optical-to-electrical conversion unit, and a shunt circuit. The optical-to-electrical conversion unit performs optical-to-electrical conversion on an optical signal received by the detection unit, to obtain a current signal including a first current signal. The shunt circuit may shunt the first current signal to obtain N second current signals used to generate N second voltage signals.

Abstract: Example methods, devices, and computer program products are provided. An example method includes receiving, by a third process, a first render tree generated by a first process. The first render tree is configured to draw an interface associated with the first process and a first display region. The method includes generating, by the third process, a first interface based on the first render tree. The first interface comprises the interface associated with the first process, on the first display region. The method includes receiving, by a fourth process, a second render tree generated by a second process. The second render tree is configured to draw an interface associated with the second process, on the first display region. The method includes generating, by the fourth process, a second interface based on the second render tree. The second interface comprises the interface associated with the second process, on a second display region.

Abstract: A call processing method comprises: a network device receives a call request message sent by an originating UE, determines, according to the call request message, that the originating UE supports a resource reservation procedure, and further transmits, to a media server, indication information indicating that use of the resource reservation procedure for negotiation about first media is not supported and use of the resource reservation procedure for negotiation about second media is supported, so that negotiation about the second media is implemented by using the resource reservation procedure.
