Abstract

A web-based video editing system includes a communication device configured to: generate information indicative of points of interest of a video, the points of interest being indicative of one or more active data or one or more inactive data during a selected time interval; determine an identity of each of the active data, and a required amount of an identified active data during the selected time interval; and request the identified active data and the required amount of each of the identified active data. The system also includes: a web server configured to: receive the requested information, assign a unique identifier to the identified active data and transmit a redirect to the communication device. The system also includes: a custom web server configured to: receive and transmit to the communication device information indicative of the unique identifiers and the required amount of each of the identified active data.

Claims

1. A public network based video system having flow control, the system comprising:

a network server configured to;

a communication device configured to;

receive the data stream;

analyze the data stream to determine a timing of presentation of the temporal and non-temporal elements to determine a data rate requirement for a future period of time; and

send a request to the server to send particular elements of the audiovisual sequence, the request including a data rate requirement for the requested elements;

the network server further configured to;

include the particular elements in the data stream; and

send the data stream at a data rate according to the data rate requirement.

2. The system of claim 1 wherein the network server is further configured to send data indicative of data rates for one or more elements to be included in the data stream, directed to the communication device, via the public network.

3. The system of claim 2 wherein the network server is further configured to:

assign a unique identifier to one of the elements; and

transmit redirection data for the one of the elements and the unique identifier to the communication device;

the network server further a custom network server, the custom network server configured to;

receive information, according to the redirection information, indicative of the unique identifier and a data rate requirement for each of the one or more identified active data; and

the custom network server it configured to;

include the particular elements in the data stream; and

send the data stream at a data rate according to the data rate requirement.

4. The system of claim 3 wherein the redirection information for at least two of the elements in the audiovisual sequence includes different domain name server portions of a resource locator.

5. The system of claim 1 wherein the system comprises a video editing system.

6. The system of claim 5 wherein the network server is further configured to:

receive instructions to modify the elements to be included in the data stream after the data stream has begun being sent by the network server.

7. The system of claim 1 wherein the communications device comprises at least one selected from the group consisting of:

a personal computer, a laptop computer, a handheld computer, a phone, and a video player.

8. The system of claim 1 wherein the public network is the Internet.

9. A public network based video system having flow control, the video system comprising:

a web server configured to;

send a data stream representative of an audiovisual sequence, directed to a communication device, via a public network, the audiovisual sequence including one or more temporal elements and one or more non-temporal elements;

receive information indicative of one or more of the elements of the audiovisual sequence to be sent in the data stream and a required data rate for the indicated elements;

include the indicated elements in the data stream; and

send the data stream at a data rate according to the required data rate while the data stream includes the indicated elements.

10. The system of claim 9 wherein the network server is further configured to send data indicative of data rates for one or more elements to be included in the data stream, directed to the communication device, via the public network.

11. The system of claim 10 wherein the network server is further configured to:

assign a unique identifier to one of the elements; and

transmit redirection data for the one of the elements and the unique identifier to the communication device;

the network server further a custom network server, the custom network server configured to;

receive information, according to the redirection information, indicative of the unique identifier and a data rate requirement for each of the one or more identified active data; and

the custom network server it configured to;

include the particular elements in the data stream; and

send the data stream at a data rate according to the data rate requirement.

12. The system of claim 11 wherein the redirection information for at least two of the elements in the audiovisual sequence includes different domain name server portions of a resource locator.

13. The system of claim 12 wherein the system comprises a video editing system.

14. The system of claim 9 wherein the network server is further configured to:

receive instructions to modify the elements to be included in the data stream after the data stream has begun being sent by the network server.

15. The system of claim 9 wherein the public network is the Internet.

16. A public network video system having flow control, the system comprising:

a communication device configured to;

receive a data stream representative of an audiovisual sequence from a server via a public network, the audiovisual sequence including one or more temporal elements and one or more non-temporal elements;

analyze the data stream to determine a timing of presentation of the temporal and non-temporal elements to determine a data rate requirement for a future period of time;

send a request to the server for transmission of particular elements of the audiovisual sequence, the request including a data rate requirement for the requested elements

17. The system of claim 16 wherein the communication device is further configured to receive data indicative of data rates for one or more elements to be included in the data stream.

18. The ys term of claim 16 wherein the system comprises a video editing system.

19. The system of claim 18 wherein the communication device is further configured to:

send instructions to modify the elements to be included in the data stream after the data stream has begun being received by the communication device.

20. The system of claim 16 wherein the communications device comprises at least one selected from the group consisting of:

a personal computer, a laptop computer, a handheld computer, a phone, and a video player.

21. The system of claim 16 wherein the public network is the Internet.

22. A method of network based video transmission having flow control, the method comprising:

sending a data stream representative of an audiovisual sequence, from a network server directed to a communication device, via a public network, the audiovisual sequence including one or more temporal elements and one or more non-temporal elements; and

receiving the data stream by the communication device;

analyzing, by the communication device, the data stream to determine a timing of presentation of the temporal and non-temporal elements to determine a data rate requirement for a future period of time;
