Abstract: A network quality measurement method and system are provided. In the method, a movement path and a movement speed of a vehicle device are determined according to a size of a space and an endurance time of the vehicle device, and the vehicle device is controlled to move on the movement path at the movement speed. During a movement of the vehicle device, a network quality in the space is measured according to a measurement frequency to generate network quality data. Whether the network quality in the space is changed is determined according to the network quality data. Whether there is an obstacle around the vehicle device is detected. When it is determined that the network quality in the space is changed or the obstacle is detected around the vehicle device, at least one of the movement path, the movement speed, and the measurement frequency is adjusted.

Abstract: An image capturing method and an image capturing apparatus are provided. An inspection region image of an inspection region is captured by a first image capturing device at a first time point. A control signal is received at a second time point after the first time point. A relative translation relationship and/or a relative rotation relationship of the first image capturing device at the first time point and a second image capturing device at a second time point are calculated. A first three-dimensional coordinate value of the local region relative to the first image capturing device is calculated and the first three-dimensional coordinate value is transformed to a second three-dimensional coordinate value relative to the second image capturing device according to the relative translation relationship and the relative rotation relationship. The second image capturing device is driven to rotate. A local region image of the local region is captured.

Abstract: A method for audio and video control response and bandwidth adaptation based on network streaming applications is disclosed. A server delivers a received control command to a stream controller while a player empties the expired streaming data stored in a buffer thereof. The stream controller controls the input source of a video/audio capturer. The receiver buffer estimator of the receiver estimates whether the amount of the streaming data stored in the buffer is within a safe range and delivers the estimation result and bandwidth variation information to a stream adaptor. If the amount of the stream data is less than a threshold value, the timestamp scalar is adjusted based on the estimation result and the bandwidth variation information, thereby adjusting the consumption rate of the streaming data in the buffer of the player for re-accumulating streaming data of the buffer.
