Abstract: A data transmission method and an electronic apparatus are disclosed. The data transmission method comprises: establishing transmission channels between the local endpoints and a plurality of remote endpoints, wherein at least one of the local endpoints corresponds to at least two of the remote endpoints and at least two transmission channels are established; and transmitting data by using the transmission channels in a time-slice manner between the local endpoints and the corresponding remote endpoints. The data transmission method and the electronic apparatus of the present disclosure can achieve data transmission between a USB host and a plurality of USB devices even when the number of remote endpoints included in the USB devices is greater than the number of local endpoints included in the USB host.

Abstract: The invention provides a navigation device capable of playing voice guidance. In one embodiment, the navigation device comprises a GNSS receiver, a Geographic Information System (GIS), a control module, an audio processing module, and a speaker. The GNSS receiver provides a position, a velocity, and an acceleration of the navigation device. The GIS determines a route according to a map data and determines a decision point in the route. The control module dynamically determines a playing policy corresponding to the decision point according to the position, velocity, and acceleration, and generates a guiding sentence corresponding to the decision point according to the playing policy, wherein the playing policy determines a number of words in the guiding sentence. The audio processing module then generates a guiding voice signal corresponding to the guiding sentence. The speaker then plays the guiding voice signal.
