Abstract

According to example configurations, a digital asset manager receives a digital asset. The digital asset manager generates multiple sets of thumbnail data based on the digital asset. Each of the multiple sets of thumbnail data can be encoded to support display of a different thumbnail resolution of the digital asset. The digital asset manager initiates storage of the multiple sets of thumbnail data in a unit of storage of a repository. The unit of storage can be pre-allocated for storing the multiple sets of thumbnail data associated with the digital asset. Accordingly, in lieu of storing data for each thumbnail in a different file as in conventional methods, configurations herein can include storing thumbnail data in the same unit of storage or file. Thus, multiple sets of thumbnail data for a corresponding digital asset can be stored in a single file.

Claims

1. A method comprising:

receiving a digital asset;

generating, based on the digital asset, multiple sets of thumbnail data for different sized thumbnails, each of the multiple sets of thumbnail data encoded to support display of a respective thumbnail rendition of the digital asset at a different respective thumbnail resolution; and

storing the multiple sets of thumbnail data in a thumbnail file stored as a single unit of storage partitioned into preallocated regions,

each preallocated region having a different respective size,

the size of each preallocated region corresponding to a maximum size of thumbnail data that can reside therein,

wherein multiple thumbnail files are created for multiple digital assets by partitioning each of the multiple thumbnail files into the preallocated regions, wherein common offset locations in each of the respective thumbnail files identify where thumbnail data supporting particular thumbnail resolutions are stored; and

wherein, when the thumbnail file is used by a recipient device, the recipient device retrieves thumbnail data supporting a thumbnail resolution of interest by identifying an offset location of a preallocated region in the thumbnail file corresponding to the thumbnail resolution of interest.

2. The method as in claim 1 further comprising:

initiating storage of at least a portion of the digital asset in a second file, the second file corresponding to a second unit of storage allocated to store the digital asset.

3. The method as in claim 1 further comprising:

receiving a command to modify the digital asset;

in response to receiving the command, modifying the digital asset and the multiple sets of thumbnail data based on the modified digital asset; and

updating the file to store the modified multiple sets of thumbnail data and the modified digital asset.

4. The method as in claim 1 further comprising:

receiving a command to retrieve data representing a rendition of the digital asset;

determining at least one of the multiple sets of thumbnail data in the file that corresponds to the data representing the rendition of the digital asset;

identifying the pre-allocated region of the file that includes the determined at least one of the multiple sets of thumbnail data; and

transmitting the at least one of the multiple sets of thumbnail data in the file to a remote resource for rendering a version of the digital asset via a thumbnail.

5. The method as in claim 1, wherein the generating the multiple sets of thumbnail data based on the digital asset comprises:

generating a first set of thumbnail data, the first set of thumbnail data encoded to render the digital asset according to a first display resolution; and

generating a second set of thumbnail data, the second set of thumbnail data encoded to render the digital asset according to a second display resolution, the second display resolution being different than the first display resolution.

6. The method as in claim 5 further comprising:

allocating a first portion of the single unit of storage to store the first set of thumbnail data, the first portion being a first predetermined size; and

allocating a second portion of the single unit of storage to store the second set of thumbnail data, the second portion being a second predetermined size.

7. The method as in claim 6, wherein storing the multiple sets of thumbnail data in a thumbnail file stored as a single unit of storage partitioned into preallocated regions comprises:

initiating storage of the first set of thumbnail data and the second set of thumbnail data in the single unit of storage allocated to store the multiple sets of thumbnail data, the first portion of the single unit of storage being larger in size than an amount of storage resources needed to store the first set of thumbnail data, the second portion of the single unit of storage being larger in size than an amount of storage resources needed to store the second set of thumbnail data.

8. The method as in claim 1 further comprising:

in response to receiving a command, initiating distribution of the multiple sets of thumbnail data stored in the single unit of storage.

9. The method as in claim 1 further comprising:

receiving a request to display a thumbnail rendition of the digital asset;

identifying, in the multiple sets of thumbnail data, a given set of thumbnail data that satisfies the request;

identifying a second offset location in the single unit of storage assigned to store the given set of thumbnail data;

retrieving the given set of thumbnail data based on the second offset location; and

transmitting the given set of thumbnail data to a remote resource to display the thumbnail rendition of the digital asset.

10. The method as in claim 1 further comprising:

for a first digital asset of the multiple digital assets, allocating a first file to store the multiple sets of thumbnail data associated with the first digital asset, the first file corresponding to the single unit of storage;

storing a first set of the multiple sets of thumbnail data associated with the first digital asset in a first allocated portion of the first file, the first allocated portion of the first file being of a first predetermined size;

storing a second set of the multiple sets of thumbnail data associated with the first digital asset in a second allocated portion of the first file, the second allocated portion of the first file being of a second predetermined size;

for a second digital asset of the multiple digital assets, allocating a second file to store the multiple sets of thumbnail data associated with the second digital asset, the second file corresponding to a second single unit of storage;

storing a first set of the multiple sets of thumbnail data associated with the second digital asset in a first allocated portion of the second file, the first allocated portion of the second file being a same size as the first allocated portion of the first file; and

storing a second set of the multiple sets of thumbnail data associated with the second digital asset in a second allocated portion of the second file, the second allocated portion of the second file being a same size as the second allocated portion of the first file.

11. The method as in claim 10 further comprising:

ordering the allocated portions in the first file and second file from smaller to larger.

12. The method as in claim 10 further comprising:

producing the first set of thumbnail data associated with the first digital asset as first compressed data for rendering the first digital asset according to a first resolution, the first compressed data occupying less than the first allocated portion of the first file; and

producing the first set of thumbnail data associated with the second digital asset as second compressed data for rendering the second digital asset according to the first resolution, the second compressed data being of a different size than the first compressed data, the second compressed data occupying less than the first allocated portion of the second file.

13. The method of claim 1, further comprising:

providing a set of thumbnail data of the multiple sets of thumbnail data, upon receiving a request to provide the set of thumbnail data, by determining the pre-allocated region in the single unit of storage where the requested set of thumbnail data is stored.

14. A computer system comprising:

a processor;

a memory unit that stores instructions associated with an application executed by the processor; and

an interconnect coupling the processor and the memory unit, enabling the computer system to execute the application and perform operations of;

receiving a digital asset;

generating, based on the digital asset, multiple sets of thumbnail data for different sized thumbnails, each of the multiple sets of thumbnail data encoded to support display of a respective thumbnail rendition of the digital asset at a different respective thumbnail resolution;

storing the multiple sets of thumbnail data in a thumbnail file stored as a single unit of storage partitioned into preallocated regions,

each preallocated region having a different respective size,

the size of each preallocated region corresponding to a maximum size of thumbnail data that can reside therein,

wherein multiple thumbnail files are created for multiple digital assets by partitioning each of the multiple thumbnail files into the preallocated regions, wherein common offset locations in each of the respective thumbnail files identify where thumbnail data supporting particular thumbnail resolutions are stored; and

wherein, when the thumbnail file is used by a recipient device, the recipient device retrieves thumbnail data supporting a thumbnail resolution of interest by identifying an offset location of a preallocated region in the thumbnail file corresponding to the thumbnail resolution of interest.

15. A method comprising:
