Screen projection data transmission method and apparatus, electronic device, and storage medium

An electronic device, comprising:

• at least one processor;
• and
• a storage apparatus configured to store at least one program;
• wherein the at least one program, when executed by the at least one processor, causes the at least one processor to perform:
• receiving feedback information which is sent by a target data reception terminal according to received screen casting data, and determining a data round-trip time of the screen casting data according to information content of a preset data transmission field in transmission control protocol (TCP) header information in the feedback information;
• estimating a network bandwidth according to a value change of the data round-trip time, and determining an adjustment strategy for a screen casting data encoding parameter based on a network bandwidth estimation result and a current data sending bandwidth;
• and
• adjusting the screen casting data encoding parameter according to the adjustment strategy, encoding to-be-sent screen casting data according to the adjusted screen casting data encoding parameter and completing data transmission.

A non-transitory storage medium comprising a computer-executable instruction, wherein the computer-executable instruction, when executed by a computer processor, is configured to execute:

• receiving feedback information which is sent by a target data reception terminal according to received screen casting data, and determining a data round-trip time of the screen casting data according to information content of a preset data transmission field in transmission control protocol (TCP) header information in the feedback information;
• estimating a network bandwidth according to a value change of the data round-trip time, and determining an adjustment strategy for a screen casting data encoding parameter based on a network bandwidth estimation result and a current data sending bandwidth;
• and
• adjusting the screen casting data encoding parameter according to the adjustment strategy, encoding to-be-sent screen casting data according to the adjusted screen casting data encoding parameter and completing data transmission.
