Abstract

A method is provided in one example and includes receiving video data propagating in a network environment; maintaining the video data in a buffer having a predetermined size; generating meta-information associated with the video data; and receiving a recording request from an end user participating in a video session associated with a video data. The recording request triggers the video data to be recorded in the network environment remote from the end user.

Claims

1. A method for providing video data recording in a network environment, comprising:

receiving video data propagating in the network environment;

maintaining the video data in a buffer having a predetermined size, wherein;

the buffer is a circular buffer that is to be hashed and shared between a first end user and a second end user, both end users participating in a video session associated with the video data;

the predetermined size of the buffer corresponds to a buffer timing recording preference of the first end user specifying a duration of video data to be maintained in the buffer, wherein the buffer timing recording preference of the first end user specifies a longer duration of video data than a duration of video data specified by the buffer timing recording preference of the second end user;

generating meta-information associated with the video data while the video data is residing in the circular buffer; and

receiving a recording request from one of the two end user participating in a video session associated with a video data, wherein the recording request triggers the video data to be recorded in the network environment remote from the end user by moving the video data from the circular buffer to another memory element that is more persistent than the circular buffer.

2. The method of claim 1, wherein the meta-information includes a selected one of a group of elements, the group consisting of:

a) optical character recognition (OCR) characteristics;

b) speech to text characteristics;

c) speaker recognition data;

d) facial recognition characteristics;

e) closed captioning information; and

f) scene change information.

3. The method of claim 1, wherein an application program interface (API) is used to provide a command for recording the video data.

4. The method of claim 1, wherein a wireless access protocol (WAP) is used to proxy certain video streams to be recorded.

5. The method of claim 1, wherein the video data that recorded is provided as a network service.

6. The method of claim 1, further comprising:

detecting activity of the first end user and the second end user based on call setup information for the video session, or a join request for the video session.

7. The method of claim 1, further comprising:

posting meta-information as an M-Track that describes certain aspects of the video data that was recorded.

8. One or more non-transitory computer readable media that includes code for execution and when executed by a processor is operable to perform operations for providing video data recording in a network environment, said operations comprising:

receiving video data propagating in the network environment;

maintaining the video data in a buffer having a predetermined size, wherein;

the buffer is a circular buffer that is to be hashed and shared between a first end user and a second end user, both end users participating in a video session associated with the video data;

the predetermined size of the buffer corresponds to a buffer timing recording preference of the first end user specifying a duration of video data to be maintained in the buffer, wherein the buffer timing recording preference of the first end user specifies a longer duration of video data than a duration of video data specified by the buffer timing recording preference of the second end user;

generating meta-information associated with the video data while the video data is residing in the circular buffer; and

receiving a recording request from one of the two end user participating in a video session associated with a video data, wherein the recording request triggers the video data to be recorded in the network environment remote from the end user by moving the video data from the circular buffer to another memory element that is more persistent than the circular buffer.

9. The one or more non-transitory computer readable media of claim 8, wherein the meta-information includes a selected one of a group of elements, the group consisting of:

a) optical character recognition (OCR) characteristics;

b) speech to text characteristics;

c) speaker recognition data;

d) facial recognition characteristics;

e) closed captioning information; and

f) scene change information.

10. The one or more non-transitory computer readable media of claim 8, wherein an application program interface (API) is used to provide a command for recording the video data.

11. The one or more non-transitory computer readable media of claim 8, wherein a wireless access protocol (WAP) is used to proxy certain video streams to be recorded.

12. The one or more non-transitory computer readable media of claim 8, wherein the video data that recorded is provided as a network service.

13. The one or more non-transitory computer readable media of claim 8, the operations further comprising:

detecting activity of the first end user and the second end user based on call setup information for the video session, or a join request for the video session.

14. The one or more non-transitory computer readable media of claim 8, the operations further comprising:

posting meta-information as an M-Track that describes certain aspects of the video data that was recorded.

15. An apparatus for providing video data recording in a network environment, said apparatus comprising:

a memory element configured to store data;

a processor operable to execute instructions associated with the data;

a recording element configured to interface with the memory element and the processor such that the apparatus is configured for;

receiving video data propagating in the network environment;

maintaining the video data in a buffer having a predetermined size, wherein;

the buffer is a circular buffer that is to be hashed and shared between a first end user and a second end user, both end users participating in a video session associated with the video data;

the predetermined size of the buffer corresponds to a buffer timing recording preference of the first end user specifying a duration of video data to be maintained in the buffer, wherein the buffer timing recording preference of the first end user specifies a longer duration of video data than a duration of video data specified by the buffer timing recording preference of the second end user;

generating meta-information associated with the video data while the video data is residing in the circular buffer; and

receiving a recording request from one of the two end user participating in a video session associated with a video data, wherein the recording request triggers the video data to be recorded in the network environment remote from the end user by moving the video data from the circular buffer to another memory element that is more persistent than the circular buffer.

16. The apparatus of claim 15, wherein an application program interface (API) is used to provide a command for recording the video data.

17. The apparatus of claim 15, wherein a wireless access protocol (WAP) is used to proxy certain video streams to be recorded.

18. The apparatus of claim 15, wherein the video data that recorded is provided as a network service.

19. The apparatus of claim 15, wherein activity of the first end user and the second end user is detected based on call setup information for the video session, or a join request for the video session.

20. The apparatus of claim 15, wherein meta-information is posted as an M-Track that describes certain aspects of the video data that was recorded.
