Abstract

A video ingest system, including a video server, including a receiver for receiving incoming video feeds, a video encoder for encoding incoming video feeds on-the-fly to one or more versions of high resolution video sample data, and to one or more versions of low resolution video sample data, and a transmitter for transmitting versions of the low resolution video sample data to respective ones of a plurality of storage units, and for transmitting high resolution video sample data to a broadcaster, a plurality of storage units, coupled communicatively with the video server, and a plurality of workstations, coupled communicatively with respective ones of the plurality of storage units, each workstation including a receiver for receiving a version of the low resolution video sample data from a storage unit, a video previewer for rendering the version of the low resolution video sample data, and a proxy video editor for generating edit instructions for the low resolution video sample data that is rendered by said video previewer.

Claims

1. A video ingest system, comprising:

a video server, comprising;

a receiver for receiving incoming video feeds;

a video encoder for encoding incoming video feeds on-the-fly to one or more versions of high resolution video sample data, and to one or more versions of low resolution video sample data; and

a transmitter for transmitting versions of the low resolution video sample data to respective ones of a plurality of storage units, and for transmitting high resolution video sample data to a broadcaster;

a plurality of storage units, coupled communicatively with said video server; and

a plurality of workstations, coupled communicatively with respective ones of said plurality of storage units, each workstation comprising;

a receiver for receiving a version of the low resolution video sample data from a storage unit;

a video previewer for rendering the version of the low resolution video sample data; and

a proxy video editor for generating edit instructions for the low resolution video sample data that is rendered by said video previewer.

2. The system of claim 1, further comprising a backup storage unit communicatively coupled with said video server and with said plurality of storage units, and wherein said video server transmitter transmits a version of the high resolution video data to said backup storage unit.

3. The system of claim 1 wherein said video server further comprises an administrative console interface for specifying formats of the one or more versions of high resolution video sample data and the one or more versions of low resolution video sample data for said video server encoder to encode, and for specifying the respective storage units to which said video server transmitter transmits the formatted versions.

4. The system of claim 1 wherein at least one of the versions of the low resolution video sample data is formatted as I-frames with non-interlaced audio tracks, and low bit-rate.

5. The system of claim 1 wherein at least one of the versions of the low resolution video sample data is formatted as long MPEG groups of pictures, and low bit-rate.

6. The system of claim 1 wherein at least one of the versions of the low resolution video sample data is formatter as a two-pass Windows Media Video.

9. The method of claim 1 wherein said transmitting conforms to a user-specified set of storage units corresponding to the user-specific set of formats.

7. A method for video ingest, comprising:

receiving, by a video server, an incoming video feed;

encoding, by the video server, the incoming video feed on-the-fly to one or more versions of high resolution video sample data and to one or more versions of low resolution video sample data;

transmitting, by the video server, the versions of the low resolution video sample data to respective ones of a plurality of storage units, as said encoding is being performed; and

further transmitting, by the video server, high resolution video sample data to a broadcaster.

8. The method of claim 7 wherein said encoding conforms to a user-specified set of formats of the one or more versions of high resolution video sample data and the one or more versions of low resolution video sample data.

10. The method of claim 7 further comprising transmitting, by the video server, a version of the high resolution video sample data to a backup storage unit.

11. The method of claim 7 further comprising transmitting, by the video server, a version of the high resolution video sample data to a storage unit dedicated to the video server.

12. The method of claim 7 wherein one or more of the versions of the video sample data are recovery sources, from which the other versions may be generated, and wherein said transmitting further comprises:

when transmission of a version of video sample data fails;

deleting an incomplete version of the video sample data created on the local storage unit;

when the version of the video sample data is a recovery source, re-attempting transmission of the version; and

when the version of the video sample data is not a recovery source, terminating transmission of the version; and

generating each version of video sample data that was not transmitted successfully, from a recovery source.

13. The method of claim 7 wherein at least one of the versions of the low resolution video sample data is formatted as I-frames with non-interlaced audio tracks, and low bit-rate.

14. The method of claim 7 wherein at least one of the versions of the low resolution video sample data is formatted as long MPEG groups of pictures, and low bit-rate.

15. The method of claim 7 wherein at least one of the versions of the low resolution video sample data is formatter as a two-pass Windows Media Video.
