Abstract: A transmission method, apparatus, and system implement bidirectional transmission of an audio/video signal between peer devices. The transmission system may include a first transmission apparatus and a second transmission apparatus, where the first transmission apparatus is connected to the second transmission apparatus through a first cable, and the first cable includes a first number of main downlink lanes and a second number of main uplink lanes. Bidirectional transmission of the audio/video signal between the first transmission apparatus and the second transmission apparatus is performed through the first cable.

Abstract: Embodiments of this application disclose a video switching method and a related device, and are applied to the multimedia field. The method in embodiments of this application includes: A video transmit end receives a video switching instruction when sending a first video frame, where the first video frame is one frame of video data of a first video stream that is being sent by the video transmit end; and the video transmit end switches video data in response to the video switching instruction when a first field blanking period after the first video frame arrives. In embodiments of this application, a video data switching process of the video transmit end may be controlled to occur in the field blanking period, and the video transmit end always sends a complete video frame to a video receive end.

Abstract: An embodiment provides a packet transmission method and apparatus, to resolve a problem that occurs when a packet cannot traverse a NAT device when VTEPs communicate with each other through the NAT device. The method is applied to a VXLAN including a first VTEP, a second VTEP, and a NAT device. The method includes: performing, by the first VTEP, VXLAN encapsulation on a first packet, obtaining a second packet; sending, by the first VTEP, the second packet to the second VTEP through the NAT device; and performing, by the second VTEP, VXLAN decapsulation on the received second packet, to obtain the first packet. The first packet is a packet to be sent by the first VTEP, a destination port number of the second packet is obtained based on a destination IP address of the second packet, and a source port number of the second packet is a preset port number.
