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 receiving end;

calculating data receiving ability of the receiving end 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;

to 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 is frame segments of the stream to the receiving end in turn according to the data receiving ability.

2. The method for transmitting data stream according to claim 1, wherein the data receiving ability is calculated by the following formula:

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

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

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

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

9. The method for transmitting data stream according to claim 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.

10. The method for transmitting data stream according to claim 9, wherein the step of transmitting the I frame segments, the P frame segments, and the B frame segments of the stream to the receiving end in turn 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 receiving end in turn according to the data receiving ability.
