Image buffering techniques

1. An apparatus, comprising:

a buffer having a fixed number of storage slots, each storage slot to store a reconstructed picture representation received from an image processing module;

a buffer status unit to store a plurality of information items, the plurality of information items to indicate one or more characteristics of the buffer; and

a buffer control module to manage storage within the buffer and to store the reconstructed picture representation in the buffer based on a type of the reconstructed picture representation, wherein one or more of the storage slots are to store a complementary pair of reconstructed first and second field picture representations based on an offset parameter.

2. The apparatus of claim 1 , wherein the plurality of information items comprises a parameter to indicate how many of the storage slots are occupied, and a data structure to indicate which of the storage slots are occupied.

3. The apparatus of claim 1 , wherein the buffer control module is to identify from the storage slots a slot having a first field picture representation corresponding to a received second field picture representation, and to store the second field picture representation in a portion of the identified slot.

4. The apparatus of claim 1 , wherein the buffer control module is to select one of the storage slots for emptying when the buffer is full.

5. The apparatus of claim 1 , wherein the buffer control module is to find an available slot within the buffer.

6. The apparatus of claim 1 , further comprising the image processing module, wherein the image processing module includes a video decoder.

7. The apparatus of claim 6 , wherein the video decoder is an H.264 based video decoder.

8. The apparatus of claim 6 , further comprising a display to output one or more decoded pictures received from the video decoder.

9. An apparatus, comprising:

a video decoder to generate decoded video signals according to an inter-prediction technique, the inter-prediction technique employing a plurality of reconstructed reference picture representations;

a buffer having a fixed number of storage slots to store the plurality of reconstructed reference picture representations;

a buffer status unit to store a plurality of information items, the plurality of information items to indicate one or more characteristics of the buffer; and

a buffer control module to manage storage within the buffer and to store the reconstructed picture representation in the buffer based on a type of reconstructed picture representation, wherein one or more of the storage slots are to store a complementary pair of reconstructed first and second field picture representations based on an offset parameter.

10. The apparatus of claim 9 , wherein the buffer control module is to identify from the storage slots a slot having a first field picture corresponding to a received second field picture, and to store the second field picture in a portion of the identified slot.

11. The apparatus of claim 9 , wherein the buffer control module is to select one of the storage slots for emptying when the buffer is full.

12. The apparatus of claim 9 , wherein the buffer control module is to find an available slot within the buffer.

13. The apparatus of claim 9 , wherein the video decoder is an H.264 based video decoder.

14. A method, comprising:

allocating a buffer having a fixed number of storage slots;

receiving a reconstructed reference picture from a video decoder;

identifying one of the storage slots for the reconstructed picture based on a type of the reconstructed reference picture, wherein one or more of the storage slots are to store a complementary pair of reconstructed first and second field picture representations based on an offset parameter; and

storing the reconstructed picture in the identified storage slot based on the type of reconstructed picture representation.

15. The method of claim 14 , further comprising emptying one of the storage slots when the buffer is full; and wherein identifying the one storage slot comprises selecting the emptied storage slot.

16. The method of claim 14 :

wherein the reconstructed reference picture is a field picture corresponding to a complementary field picture stored in one of the storage slots; and

wherein identifying the one storage slot comprises selecting a storage slot containing the complementary field picture.

17. The method of claim 14 , further comprising maintaining a plurality of information items to indicate one or more characteristics of the buffer, the plurality of information items comprising a parameter to indicate how many of the storage slots are occupied, and a data structure to indicate which of the storage slots are occupied.

18. An article comprising a machine-readable storage medium containing instructions that if executed enable a system to:

allocate a buffer having a fixed number of storage slots;

receive a reconstructed reference picture from a video decoder;

identify one of the storage slots for the reconstructed picture based on a type of the reconstructed reference picture, wherein one or more of the storage slots are to store a complementary pair of reconstructed first and second field picture representations based on an offset parameter; and

store the reconstructed picture in the identified storage slot based on the type of reconstructed picture representation.
