Abstract

A digital video logging system including a logging apparatus able to synchronize at least two digitally formatted video input and digital storage apparatus to store the digitally formatted input is provided.

Claims

1. A method comprising synchronizing at least two digitally formatted video inputs.

2. A method comprising compressing at different compression ratio video inputs received from different input devices.

3. The method of claim 2 further comprising varying the compression ratio for one of more of said inputs devices from time to time.

4. A method comprising:

receiving input from one or more input devices, said input devices are any of a group including a video input device and an audio device; and

synchronizing said input received from more than one of said input devices.

5. The method of claim 4 further comprising selectively providing said input to storage apparatus.

6. The method of claim 4 further comprising selectively providing said input to output apparatus.

7. The method of claim 4 further comprising associating at least a portion of said input with one or more datum from a group including:

an input channel datum, a time datum, a data datum, a non-ambient characteristic datum and a trigger datum; and

maintaining said one or more datum in a database.

8. The method of claim 7 further comprising:

accepting a query comprising at least one of said datum; and

instructing said logging apparatus to retrieve at least said portion associated with at least one of said datum from a digital apparatus and to provide said portion to an output apparatus.

9. The method of claim 4 further comprising:

detecting a non-ambient characteristic associated with at least a portion of said input, said portion associated with at least one of said input devices; and

providing at least said portion to a storage apparatus subsequent to said non-ambient characteristic being detected.

10. The method of claim 4 further comprising selectively controlling one or more of said input devices to provide said input therefrom.

11. The method of claim 10, wherein said controlling is activating or deactivating in accordance with a predetermined schedule.

12. A digital video logging system comprising:

A logging apparatus able to synchronize at least two digitally formatted video input; and

digital storage apparatus to store said digitally formatted input.
