Abstract

Systems and methods are provided for the reconstruction of a video and audio recording of stored or transmitted media streams, using a proprietary file format or protocol.

Claims

1. A computer-implemented method for reconstructing a media stream, comprising:

obtaining a first modified media stream of an original media stream;

obtaining a second modified media stream of the original media stream;

normalizing the first and second modified media streams to create corresponding normalized first and second media streams;

aligning the first and second normalized media streams to;

identify standard headers and standard trailers in at least the first normalized media stream;

identify a media data payload in at least the first normalized media stream; and

,

identify proprietary headers and proprietary trailers in at least the first normalized media stream; and

,

reconstructing the original media stream based on the identifications from the alignment of the first and second normalized media streams.

2. The computer-implemented method of claim 1, additionally comprising:

outputting the reconstructed media stream.

3. The computer-implemented method of claim 1, wherein the reconstructed media stream includes the identified:

1) standard headers;

     2) standard trailers; and

,

     3) media data payloads.

4. The computer-implemented method of claim 1, additionally comprising:

replacing the identified proprietary headers with replacement standard headers; and

/or replacing the identified proprietary trailers with replacement standard trailers; and

,

the reconstructed media stream includes the identified;

     1) standard headers,

     2) standard trailers,

     3) media data payloads, and

     4) replacement standard headers.

5. The computer-implemented method of claim 4, additionally comprising:

outputting the reconstructed media stream.

6. The computer-implemented method of claim 1, wherein the first modified media stream and the second modified media stream include transmitted modified media streams.

7. The computer-implemented method of claim 1, wherein the first modified media stream and the second modified media stream include stored modified media streams.

8. The computer-implemented method of claim 1, wherein at least one of the first modified media stream or the second modified media stream includes a transmitted modified media stream, and, the other of the first modified media stream or the second modified media stream includes a stored modified media stream.

9. The computer-implemented method of claim 1, wherein the original media stream, the first modified media stream and the second modified media stream include at least one of:

audio content, video content and/or audio and video content.

10. A computer usable non-transitory storage medium having a computer program embodied thereon for causing a suitably programmed system to reconstruct a media stream from at least two modified media streams, by performing the following steps when such program is executed on the system, the steps comprising:

obtaining a first modified media stream of an original media stream;

obtaining a second modified media stream of the original media stream;

normalizing the first and second modified media streams to create corresponding normalized first and second media streams;

aligning the first and second normalized media streams to;

identify standard headers and standard trailers in at least the first normalized media stream;

identify a media data payload in at least the first normalized media stream; and

,

identify proprietary headers and proprietary trailers in at least the first normalized media stream; and

,

reconstructing the original media stream based on the identifications from the alignment of the first and second normalized media streams.

11. The computer-usable non-transitory storage medium of claim 10, wherein the reconstructed media stream includes the identified:

1) standard headers;

     2) standard trailers; and

,

     3) media data payloads.

12. The computer-usable non-transitory storage medium of claim 11, wherein the steps additionally comprise:

replacing the identified proprietary headers with replacement standard headers; and

/or replacing the identified proprietary trailers with replacement standard trailers; and

,

the reconstructed media stream includes the identified;

     1) standard headers,

     2) standard trailers,

     3) media data payloads, and

     4) replacement standard headers.

13. The computer-usable non-transitory storage medium of claim 12, wherein the steps additionally comprise:

outputting the reconstructed media stream.

14. The computer-usable non-transitory storage medium of claim 10, wherein the first modified media stream and the second modified media stream include transmitted modified media streams.

15. The computer-usable non-transitory storage medium of claim 10, wherein the first modified media stream and the second modified media stream include stored modified media streams.

16. The computer-usable non-transitory storage medium of claim 10, wherein at least one of the first modified media stream or the second modified media stream includes a transmitted modified media stream, and, the other of the first modified media stream or the second modified media stream includes a stored modified media stream.
