Method for transmitting stream between electronic devices and electronic device for the method thereof

摘要

A technique for transmitting a video stream between a first electronic device and a second electronic device is provided. The first device receives an encoded video stream and determines whether an encoding format of the encoded video stream is a format decodable by a second electronic device. If the format is decodable, the encoded video stream is transmitted without a re-encoding operation to the second device. The video stream is displayed at the first device delayed by a determined delay time enabling the video stream to be displayed at the second device substantially synchronized with the display at the first device.

主权项

1. A method operable in a first electronic device; comprising:
decoding an encoded video stream to generate a decoded video stream to be displayed on a display of the first electronic device; extracting, from a packet of the encoded video stream, frame time information of the encoded video stream; monitoring an output frame of the decoded video stream so as to derive a decoding time of the output frame using the frame time information of the encoded video stream; and wirelessly transmitting the encoded video stream directly to a second electronic device via a short range wireless communications protocol, after delaying by a determined time computed at least in part from the decoding time, to enable displaying of the video stream on the second electronic device in synchronism with the displaying of the decoded video stream on the first electronic device.
