Abstract

A method for playing back video files optimizes display viewing while minimizing file size. On of a plurality of video files representing the same video production is automatically selected for viewing based on multiple criteria, such as network bandwidth, the type of video players available to display the video file, the format of the video file and the platform used to display the file. The width and height of the image displayed from the selected video file is adjusted to match the resolution of a display screen, or a user specified image size. A system for transmitting and displaying large media files uses an online streaming service to upload full-length movies and other video and audio files to a wide array of viewers. The system includes a robust, scalable, and fat upload technique that allows files of any size to be uploaded to customers'"'"' accounts by the customers. It is specifically tuned to handle hundreds of uploads per second of files which are typically several hundred mega bytes large. Increased scalability is achieved by clustering servers behind a front-end server than gives customers a relative level of distribution transparency.

Claims

1-53. -53. (canceled)

54. A video play-back method, the method on a server comprising:

receiving over a network from at least one client system, a plurality of parameters related to video play-back capabilities which include a resolution of a display of the client system;

calculating at least one optimization factor based on the parameters received from the client system;

selecting, based on the optimization factor, one from at least two videos representing an identical video production but having differing video play-back qualities, wherein the video play-back qualities include at least one of a height and a width of the video associated with the optimization factor which has been calculated; and

sending over the network to the client system a video which has been selected from the at least two videos.

55. The method of claim 54, wherein the receiving over a network from at least one client system, includes receiving the parameters by a portal server;

and

wherein the selecting, based on the optimization factor, one from at least two videos representing an identical video production but having differing video play-back qualities, includes selecting from a plurality of media servers each storing at least two videos.

56. The method of claim 55, wherein at least one of the plurality of servers stores multimedia files for delivery in a first protocol and at least one of the plurality of servers stores media files for delivery in a second protocol.

57. The method of claim 55 further comprising:

authenticating on the portal server security information related to the client system.

58. The method of claim 54, further comprising:

updating accounting information, in response to sending over the network to the client system a video which has been selected.

59. The method of claim 54, wherein the receiving over a network from at least one client system, includes receiving the parameters by a portal server;

and

wherein the selecting, based on the optimization factor, one from at least two videos representing an identical video production but having differing video play-back qualities, includes selecting from a plurality of media servers each storing at least two videos wherein at least one of the plurality of servers stores multimedia files for delivery in a first protocol and at least one of the plurality of severs stores media files for delivery in a second protocol and the selecting, based on the optimization factor, includes selecting both the height and the width of the videos based on the screen resolution used in the optimization factor.

60. The method of claim 54, wherein the receiving over the network from at least one client system, includes receiving at least of a height and a width of the display.

61. The method of claim 54, wherein the selecting, based on at least one optimization criterion includes an optimization factor based upon an encoding type associated with the videos.

62. The method of claim 54, wherein the receiving over a network from at least one client system includes receiving parameters for at least one of:

a type of video player available on the client system;

a bandwidth available in the network; and

a type of hand-held device used for the client system wherein the hand held platform includes at least one of a type of a hardware manufacturers a hardware model, an operating system, and a browser.

63. The method of claim 54, wherein the receiving over a network from at least one client system includes receiving parameters for a combination of:

a type of video player available on the client system; and

a bandwidth available in the network.

64. The method of claim 54, wherein the receiving over a network from at least one client system includes receiving parameters for a combination of:

a type of operating system on the client system; and

at least one of a manufacturer and model of the client system.

65. The method of claim 54, wherein the receiving over a network from at least one client system includes receiving parameters for a type of web browser available on the client system and receiving parameters for a plug-in available for the web browser on the client system.

66. The method of claim 54, further comprising:

adjusting at least one of the height and the width of the video prior to the sending over the network to the client system the video which has been selected.

67. The method of claim 63, wherein the adjusting at least one of the height and the width of the video includes adjusting at least one of the height and the width of the video based on a bandwidth available in the network.

68. The method of claim 54, wherein the step of sending over the network to the client system a video which has been selected from the at least two videos includes streaming the video which has been selected.

69. A video play-back system, comprising:

at least one host computer communicatively coupled to a storage with a plurality of media files and communicatively coupled over a network to a plurality of client systems,

wherein the host is configured to execute programming instructions for

receiving over the network from at least one of the client systems, a plurality of parameters related to video play-back capabilities which include a resolution of a display of the client system;

calculating at least one optimization factor based on the parameters received from the client system;

selecting, based on the optimization factor, one from at least two videos representing an identical video production but having differing video play-back qualities, wherein the video play-back qualities include at least one of a height and a width of the video associated with the optimization factor which has been calculated; and

sending over the network to the client system a video which has been selected from the at least two videos.

70. The video play-back system of claim 69, wherein the host system is a portal server;

and

wherein the selecting, based on the optimization factor, one from at least two videos representing an identical video production but having differing video play-back qualities, includes selecting from a plurality of servers each storing at least two videos.

71. The video play-back system claim 70, wherein at least one of the plurality of servers stores multimedia files in a proprietary format.
