Abstract: A video indexing method, a video indexing apparatus, and a computer readable medium are disclosed. The video indexing apparatus comprises a generation module, a calculation module and a construction module. The generation module generates a frame movement analysis graphics according to a plurality of analysis points corresponding to a plurality of video frames of a video record. The calculation module calculates a plurality of frame movement velocities corresponding to the video frames according to the frame movement analysis graphics. The construction module constructs an indexing graphics of the video record according to the frame movement velocities.

Abstract: A transmission rate determination method for streaming media is disclosed. The transmission rate determination method includes the following steps: collecting a location message, a time message, a communication parameter information and a transmission bit rate of a mobile device; updating a database of streaming throughput according to the location message, the time message, the communication parameter information and the transmission bit rate; wherein the database of streaming throughput includes information regarding a plurality of regions. The information of each of the plurality of regions includes an average transmission rate. The average transmission rate is related to the location message, the time message, the communication parameter information and the transmission bit rate.
