Method and system for processing video

A video processing system, comprising:

• at least one memory configured to store a source code and a data stream;
• and
• at least one processor configured to execute the source code, to:
• receive a seek command, and determine whether the data stream comprises first data corresponding to a first segment of a video or not;
• if the data stream does not comprise the first data, acquire a download link of the first segment;
• execute a weighted average method according to at least one network speed value and at least one weight, to generate a first network speed value corresponding to the first segment, wherein at least one previous segment is downloaded according to the at least one network speed value before the seek command is received;
• multiply the first network speed value and a predetermined parameter to generate an estimated network speed value;
• select a bit rate according to the estimated network speed value;
• download the first data having the bit rate from a server according to the estimated network speed value and the download link, wherein the bit rate of the first data is less than the estimated network speed value, wherein the at least one weight is associated with a first timing when the seek command is sent out;
• and
• play the first segment according to the first data, to switch from a current segment of the video to the first segment.
