Abstract
A video transmission method includes: A first media gateway receives an uplink media packet sent by a first terminal, where the uplink media packet carries information indicating that the first terminal supports an uplink-downlink resolution asymmetry capability and an uplink media stream of a first resolution of the first terminal. The first media gateway sends a first downlink media packet to the first terminal, where the first downlink media packet carries a downlink media stream of a second resolution of the first terminal, and the first resolution is different from the second resolution. The solution is applicable to the following example case: In a video call process, a terminal that supports different resolutions in a sending direction and a receiving direction can lower a resolution based on channel quality to deliver a video packet, and can raise the resolution when network resources are sufficient.
