- step ST23 after a new link is established, the process returns to step ST17.
- a change in the intelligent link mode is constantly monitored, and a change in the content type is monitored in the content priority mode. If there is a change, a new link setting corresponding to the change is performed. .
- the MHL link setting is performed between the mobile phone 100 and the television receiver 200 based on the setting information of the intelligent link mode. For this reason, for example, it is possible to change the MHL link setting content to a state desired by the user in a timely manner.
- the optimal resolution and frame rate for the content can be obtained. That is, when the content type is a sport or a game, a high frame rate link setting state is set. When the content type is photo or cinema, a high resolution link setting state is set. For example, when the energy saving mode is selected, the power consumption of the device is reduced by optimizing the transmission rate, and as a result, heat generation is suppressed and the battery duration is increased.
