Creating a Channel

Notes

• The function of connecting to third-party CDNs is available only in the AP-Singapore, ME-Riyadh, and CN-Hong Kong regions.
• In independent origin mode, extra data transmission fees are incurred when third-party CDNs access the Media Live origin server through the Internet. For more details, submit a service ticket.

Prerequisites

During the creation of a channel, the Channel Mode parameter is not available by default. You need to submit a service ticket to request access.

Procedure

The procedure is the same as that described in Creating a Channel. You only need to note that:

• On the Basic Info page for creating a channel, the Channel Mode and Channel Region parameters are available, as shown in Figure 1.
  For details about the parameter settings, see Table 1.
