Abstract

Aspects of the subject disclosure may include, for example, a video camera that includes a video capture device configured to produce a high resolution video signal. A video encoder is configured to layered video encode the high resolution video signal to generate a processed video signal, the processed video signal including a plurality of independent video layers, each of the plurality of independent video layers having a different video resolution. Other embodiments are disclosed.

First claim

What is claimed is:

1 . A video camera comprising:
a video capture device configured to produce a high resolution video signal; and a video encoder configured to layered video encode the high resolution video signal to generate a processed video signal, the processed video signal including a plurality of independent video layers, each of the plurality of independent video layers having a different video resolution.

2 . The video camera of claim 1 wherein the plurality of independent video layers are each compressed.

3 . The video camera of claim 1 wherein each the plurality of independent video layers are independently decodable without accessing any other one of each of the plurality of independent video layers.

4 . The video camera of claim 1 wherein the plurality of independent video layers include a 4K layer and at least one lower resolution layer.

5 . The video camera of claim 1 wherein the plurality of independent video layers are time synchronized to permit a video player to switch, in real time, between playback of a first layer of the plurality of independent video layers and playback of a second layer of the plurality of independent video layers.

6 . A video system comprising:
a plurality of video cameras that generates a plurality of processed video signals at differing vantage points of a common location, each video camera comprising:
a video capture device configured to produce a high resolution video signal; and
a video encoder configured to layered video encode the high resolution video signal to generate a corresponding one of the plurality of processed video signals, the plurality of processed video signals each including a plurality of independent video layers, each of the plurality of independent video layers having a different video resolution.

7 . The video system of claim 6 wherein the plurality of independent video layers are each compressed.

8 . The video system of claim 6 wherein each the plurality of independent video layers are independently decodable without accessing any other one of each of the plurality of independent video layers.

9 . The video system of claim 6 wherein the plurality of independent video layers include a 4K layer and at least one lower resolution layer.

10 . The video system of claim 6 wherein the plurality of independent video layers are time synchronized to permit a video player to switch, in real time, between playback of a first layer of the plurality of independent video layers and playback of a second layer of the plurality of independent video layers.

11 . A method comprising:
generating a high resolution video signal; and layered video encoding, via an encoding device, the high resolution video signal to generate a processed video signal, the processed video signal including a plurality of independent video layers, each of the plurality of independent video layers having a different video resolution.

12 . The method of claim 11 wherein the plurality of independent video layers are each compressed.

13 . The method of claim 11 wherein each the plurality of independent video layers are independently decodable without accessing any other one of each of the plurality of independent video layers.

14 . The method of claim 11 wherein the plurality of independent video layers include a 4K layer and at least one lower resolution layer.

15 . The method of claim 11 wherein the plurality of independent video layers are time synchronized to permit a video player to switch, in real time, between playback of a first layer of the plurality of independent video layers and playback of a second layer of the plurality of independent video layers.

16 . The method of claim 11 further comprising:
analyzing at least one of, the high resolution video signal or a reduced resolution video signal generated for formatting as one of the plurality of independent layers, to generate metadata based on a recognition of an object, person or human activity.

17 . The method of claim 16 wherein the metadata triggers a video player to automatically switch from a low resolution display of the processed video signal to a high resolution display of the processed video signal.
