4	14	Shanghai channel
			……	……	……
60	60	Channel 60

For example, in a possible embodiment, the channel change command received by the controller is "Jiangsu satellite view", and the controller identifies the channel identifier as the first identifier. The controller determines that the Jiangsu channel is the target channel based on the Jiangsu satellite television traversal first sub-table. In a possible embodiment, the channel change command received by the controller is channelNumber: "4", and the controller identifies the channel identifier channelNumber as the second identifier. The controller determines that the Jiangsu channel is the target channel based on 4 traversal of the first sub-table.
