Abstract: The present invention provides a real-time video transmission method for a multipath network. The multipath network comprises at least two video stream transmission sub-paths from a transmitting terminal to a receiving terminal. The real-time video transmission method for a multipath network comprises steps of: 1) by the transmitting terminal, packing original video stream data and sequentially adding a tag into a packet header to obtain multipath transmission data, and sending the multipath transmission data packets to different ones of the video stream transmission sub-paths for transmission; and, 2) by the receiving terminal, receiving and parsing the multipath transmission data packets, and restoring the original video data stream according to the tags in the packet headers. The present invention can take full advantage of outlet and inlet bandwidths at two ends of a transmission path, and can effectively improve stability in video transmission to improve user experience.

Abstract: An electronic device and a method for automatically converting text to be displayed on a display screen of an electronic device into a speech signal when ambient light conditions affect viewing of the text. The method is performed by the electronic device and the method includes receiving a command to display text on the display screen and determining if an ambient light signal provided by an ambient light sensor is above a pre-determined viewing threshold. This ambient light signal corresponds to ambient light conditions adjacent the display screen. The method also includes automatically converting the text to a speech signal when the ambient light signal is above the pre-determined viewing threshold. Suitably, there is performed a step of emitting the speech signal in an audible form from a speaker.
