Abstract

One example method includes receiving a generation 0 data stream, creating and/or receiving a mask that includes multiple entries, each of which corresponds to a respective block of the generation 0 data stream, and each mask entry indicating a value n (0<=n<=desired generation N), identifying, in the mask, all non-zero entries, locating, in the generation 0 data stream, the blocks to which this entry corresponds to and based on the value n, modifying the generation 0 block to generate a generation N data stream.

First claim

What is claimed is:

1. A method, comprising:
receiving a generation 0 data stream;
creating and/or receiving a mask that comprises a plurality of entries, wherein each mask entry of the plurality of entries corresponds to a respective block of the generation 0 data stream, and wherein each mask entry of the plurality of entries indicates a value n, where 0≤n≤desired generation N data stream;
identifying, in the mask, all non-zero mask entries;
locating, in the generation 0 data stream, the blocks to which the non-zero mask entries respectively correspond; and
based on the value n, modifying one or more blocks of the generation 0 data stream to create a generation N data stream at a relatively high rate using a data stream generator in accordance with one or more parameters specified by a user via a user interface.

2. The method as recited in claim 1 , wherein the value n corresponds to a particular generation of one of the one or more blocks of the generation 0 data stream.

3. The method as recited in claim 1 , wherein the mask comprises a block modification table.

4. The method as recited in claim 1 , wherein the method is performed by the data stream generator.

5. The method as recited in claim 1 , further comprising morphing the generation N data stream by multiple generations either backward to a generation N−X data stream, or forward to a generation N+X data stream, where X is ≥1.

6. The method as recited in claim 1 , further comprising creating a generation N−1 data stream using another mask at a relatively high rate using the data stream generator in accordance with the one or more parameters specified by the user via the user interface.

7. The method as recited in claim 6 , wherein the generation N−1 data stream is created before the generation N data stream.

8. The method as recited in claim 7 , further comprising ascertaining any differences between the generation N−1 data stream and the generation N data stream.

9. The method as recited in claim 8 , wherein ascertaining any differences between the generation N−1 data stream and the generation N data stream comprises comparing the mask with the another mask.

10. The method as recited in claim 1 , further comprising morphing the generation N data stream either backward to a generation N−1 data stream, or forward to a generation N+1 data stream.

11. A non-transitory storage medium having stored therein instructions which are executable by one or more hardware processors to perform operations comprising:
receiving a generation 0 data stream;
creating and/or receiving a mask that comprises a plurality of entries, wherein each mask entry of the plurality of entries corresponds to a respective block of the generation 0 data stream, and wherein each mask entry of the plurality of entries indicates a value n, where 0≤n≤desired generation N data stream;
identifying, in the mask, all non-zero mask entries;
locating, in the generation 0 data stream, the blocks to which the non-zero mask entries respectively correspond; and
based on the value n, modifying one or more blocks of the generation 0 data stream to create a generation N data stream at a relatively high rate using a data stream generator in accordance with one or more parameters specified by a user via a user interface.

12. The non-transitory storage medium as recited in claim 11 , wherein the value n corresponds to a particular generation of one of the one or more blocks of the generation 0 data stream.

13. The non-transitory storage medium as recited in claim 11 , wherein the mask comprises a block modification table.

14. The non-transitory storage medium as recited in claim 11 , wherein the operations are performed by the data stream generator.

15. The non-transitory storage medium as recited in claim 11 , wherein the operations further comprise morphing the generation N data stream by multiple generations either backward to a generation N−X data stream, or forward to a generation N+X data stream, where X is ≥1.

16. The non-transitory storage medium as recited in claim 11 , wherein the operations further comprise creating a generation N−1 data stream using another mask at a relatively high rate using the data stream generator in accordance with the one or more parameters specified by the user via the user interface.

17. The non-transitory storage medium as recited in claim 16 , wherein the generation N−1 data stream is created before the generation N data stream.

18. The non-transitory storage medium as recited in claim 17 , wherein the operations further comprise ascertaining any differences between the generation N−1 data stream and the generation N data stream.

19. The non-transitory storage medium as recited in claim 18 , wherein ascertaining any differences between the generation N−1 data stream and the generation N data stream comprises comparing the mask with the another mask.

20. The non-transitory storage medium as recited in claim 11 , wherein the operations further comprise morphing the generation N data stream either backward to a generation N−1 data stream, or forward to a generation N+1 data stream.
