A method for controlling multiple auxiliary streams, comprising: applying, by a terminal at a first site, for a presentation token; and sending, by the terminal at the first site, after applying for and obtaining the presentation token, an auxiliary stream to a terminal at a second site through a presentation auxiliary stream channel corresponding to the presentation token, and characterized by: sending, by the terminal at the first site, one other auxiliary stream to the terminal at the second site through an auxiliary stream channel bound with the presentation auxiliary stream channel, wherein the other auxiliary stream is transmitted through the auxiliary stream channel and the other auxiliary stream has a same destination site as the auxiliary stream, and the auxiliary stream channel bound with the presentation auxiliary stream channel is a live auxiliary stream channel, wherein, before the sending one other auxiliary stream to the terminal at the second site through an auxiliary stream channel bound with the presentation auxiliary stream channel, the method further comprises: sending binding relationship indication information to the terminal at the second site, wherein the binding relationship indication information indicates which live auxiliary stream channel is bound with the presentation auxiliary stream channel. applying, by a terminal at a first site, for a presentation token; and sending, by the terminal at the first site, after applying for and obtaining the presentation token, an auxiliary stream to a terminal at a second site through a presentation auxiliary stream channel corresponding to the presentation token, and characterized by: sending, by the terminal at the first site, one other auxiliary stream to the terminal at the second site through an auxiliary stream channel bound with the presentation auxiliary stream channel, wherein the other auxiliary stream is transmitted through the auxiliary stream channel and the other auxiliary stream has a same destination site as the auxiliary stream, and the auxiliary stream channel bound with the presentation auxiliary stream channel is a live auxiliary stream channel, wherein, before the sending one other auxiliary stream to the terminal at the second site through an auxiliary stream channel bound with the presentation auxiliary stream channel, the method further comprises: sending binding relationship indication information to the terminal at the second site, wherein the binding relationship indication information indicates which live auxiliary stream channel is bound with the presentation auxiliary stream channel. sending, by the terminal at the first site, one other auxiliary stream to the terminal at the second site through an auxiliary stream channel bound with the presentation auxiliary stream channel, wherein the other auxiliary stream is transmitted through the auxiliary stream channel and the other auxiliary stream has a same destination site as the auxiliary stream, and the auxiliary stream channel bound with the presentation auxiliary stream channel is a live auxiliary stream channel, wherein, before the sending one other auxiliary stream to the terminal at the second site through an auxiliary stream channel bound with the presentation auxiliary stream channel, the method further comprises: sending binding relationship indication information to the terminal at the second site, wherein the binding relationship indication information indicates which live auxiliary stream channel is bound with the presentation auxiliary stream channel. sending binding relationship indication information to the terminal at the second site, wherein the binding relationship indication information indicates which live auxiliary stream channel is bound with the presentation auxiliary stream channel.
