Abstract

A computer-implemented method/system of providing video clip playback, including: (i) receiving a video feed; (ii) converting the video feed into a compressed format structure; (iii) uploading the compressed format structure to a first server; (iv) receiving an electronic edit decision list defining how to manipulate the compressed format structure; (v) saving the electronic edit decision list to a server; (vi) receiving a request to provide to a user terminal a video clip playback corresponding to a video clip defined by the compressed format structure and the electronic edit decision list; (vii) sending to the user code executable to provide the video clip defined by the compressed format structure and the electronic edit decision list; and (viii) responding to requests from the code when executed, to provide content corresponding to the compressed format structure stored in accordance with the electronic edit decision list to provide the video clip playback.

Claims30

Dependent claims

A computer-implemented method of providing video clip playback, the method including the steps of:

(i) receiving a video feed;
(ii) converting the video feed into a compressed format structure, the compressed format structure including a hierarchy of levels of temporal resolution of frames, each respective level of the hierarchy including frames corresponding to a respective temporal resolution of the respective level of the hierarchy, but not including frames which are included in one or more lower levels of lower temporal resolution of frames of the hierarchy;
(iii) uploading the compressed format structure to a first server;
(iv) receiving an electronic edit decision list which defines how to manipulate the compressed format structure;
(v) saving the electronic edit decision list to the first server, or to a second server;
(vi) receiving a request to provide in a web browser executing on a user terminal a video clip playback corresponding to a video clip defined by the compressed format structure and the electronic edit decision list;
(vii) sending to the web browser code executable in the web browser to provide the video clip playback corresponding to the video clip defined by the compressed format structure stored on the first server and the electronic edit decision list saved on the first server or on the second server, and
(viii) responding to requests from the code when executing in the web browser, to provide content corresponding to the compressed format structure stored on the first server, in accordance with the electronic edit decision list saved on the first server or on the second server, to the web browser, to provide the video clip playbacks;
in which the compressed format structure includes loss free compression,
in which the loss free compression includes use of Transition Tables, and
in which the code uses a video codec, wherein the video codec supports private keys to randomise the initial state of its Transition Tables, making each bitstream randomised.
