Abstract

Disclosed is a method of transmitting video files, wherein an electronic device performs the steps of: (a) receiving a first video segment from time T₀ to time T₀+ΔT within a video file transmitted via a network from a video server; (b) receiving plural n_th video segments from time T_n to time T_n+ΔTT within the video file transmitted via the network from the video server, wherein n=1, 2, 3, . . . N, and N is the number of video skipping points, ΔT and ΔTT are predetermined playback length, and time T₀<time T₁<time T₂<time T₃< . . . <time T_n; (c) playing the first video segment; (d) detecting whether a skip playback command has been received while the electronic device playing the first video segment, if affirmative, the electronic device skips to play the n_th video segment, and subjecting the time T₀ of the video server to be time T_n, if negative, the electronic device continues playing the first video segment until the time T0+ΔT, and subjecting the time T₀ of the video server to be time T₀+ΔT, in which the skip playback command serves to instruct the electronic device to play the n_th video segment; and (e) repeating steps (a) to (d) until the end of the video file.

Claims

1. A method of transmitting video files, wherein the method is performed by an electronic device, the method comprising:

(a) receiving a first video segment from time T₀ to time T₀+Δ

T within a video file transmitted via a network from a video server;

(b) receiving plural n_th video segments from time Tn to time T_n+Δ

TT within the video file transmitted via the network from the video server, wherein n=1, 2, 3, . . . , N, and N is the number of video skipping points, Δ

T and Δ

TT are predetermined playback length, and time T₀<

time T₁<

time T₂<

time T₃<

. . . <

time T_n;

(c) playing the first video segment;

(d) detecting whether a skip playback command has been received while the electronic device playing the first video segment, if affirmative, the electronic device skips to play the n_th video segment, and subjecting the time T₀ of the video server to be time T_n, if negative, the electronic device continues playing the first video segment until the time T₀+Δ

T, and subjecting the time T₀ of the video server to be time T₀+Δ

T, in which the skip playback command serves to instruct the electronic device to play the n_th video segment; and

(e) repeating steps (a) to (d) until the end of the video file.

2. The method of claim 1, wherein the time T₀ and the time T_n represent the file size of the video file.

3. The method of claim 1, wherein the time T₀ and the time T_n represent the playback time of the video file.

4. The method of claim 1, wherein the electronic device is a client terminal.

5. The method of claim 1, wherein the number of the video skipping points is a predetermined number.

6. The method of claim 1, wherein the number of the video skipping points may be reconfigured.

7. The method of claim 1, wherein the electronic device is a mobile phone.

8. The method of claim 1, wherein the electronic device is a computer.

9. The method of claim 1, wherein the electronic device is a PDA.

10. The method of claim 1, wherein the network is a web network.

11. The method of claim 1, wherein the network is a local network.

12. The method of claim 1, wherein the network is a mobile digital communication network.
