1. A video transmission method, comprising:
receiving, by a first media gateway, an uplink media packet from a first terminal, wherein 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, and the uplink-downlink resolution asymmetry capability allows different resolutions in a sending direction and a receiving direction; and
sending, by the first media gateway, a first downlink media packet to the first terminal, wherein 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,
wherein the uplink-downlink resolution asymmetry capability supports different resolutions for a downlink media stream carried in a downlink media packet transmitted from the first media gateway to the first terminal and an uplink media stream carried in an uplink media packet transmitted from the first terminal to the first media gateway, and supports unidirectional resolution adjustment for adjusting resolutions in the receiving direction and the sending direction asynchronously.
