Abstract

A method for transmitting data stream includes the steps of analyzing a request to generate a transmitting command, calculating a data receiving ability of a receiving end when receiving the transferring command, calculating an I frame dividing rate, a P frame dividing rate, and a B frame dividing rate based on the data receiving ability, dividing an I frame, a P frame, and a B frame based on the I frame dividing rate, the P frame dividing rate, and the B frame dividing rate to generate a plurality of I frame segments, P frame segments, and B frame segments, transmitting the I frame segments, P frame segments, and B frame segments of the data stream to the receiving end in turn base on the data receiving ability.

Claims

1. A method for transmitting data stream, comprising:

analyzing a request to generate a transmitting command, wherein the transmitting command corresponds to a computer;

calculating data receiving ability of the computer when the transmitting command is received;

calculating a I frame dividing rate, a P frame dividing rate, and a B frame dividing rate of a stream according to the data receiving ability;

dividing an I frame, a P frame, and a B frame respectively according to the I frame dividing rate, the P frame dividing rate, and the B frame dividing rate to generate a plurality of I frame segments, P frame segments, and B frame segments; and

transmitting the I frame segments, the P frame segments, and the B frame segments of the stream to the computer in turn by a server according to the data receiving ability,

wherein the data receiving ability is calculated by the following formula;

2. The method for transmitting data stream according to claim 1, wherein the I frame dividing rate is calculated by the following formula:

3. The method for transmitting data stream according to claim 1, wherein the B frame dividing rate is calculated by the following formula:

4. The method for transmitting data stream according to claim 1, wherein the B frame dividing rate is calculated by the following formula:

5. The method for transmitting data stream according to claim 1, wherein the I frame segments is calculated by the following formula:

6. The method for transmitting data stream according to claim 1, wherein the P frame segments is calculated by the following formula:

7. The method for transmitting data stream according to claim 1, wherein the number of the divided B frame is calculated by the following formula:

8. The method for transmitting data stream according to claim 1, wherein the step of calculating the I frame dividing rate, the P frame dividing rate, and the B frame dividing rate of the stream according to the data receiving ability comprises:

calculating the I frame dividing rate, the P frame dividing rate, and the B frame dividing rate of one of a plurality of streams according to the data receiving ability.

9. The method for transmitting data stream according to claim 8, wherein the step of transmitting the I frame segments, the P frame segments, and the B frame segments of the stream to the computer in turn by the server according to the data receiving ability comprises:

transmitting the I frame segments, the P frame segments, and the B frame segments of the streams to the computer in turn by the server according to the data receiving ability.
