Methods and apparatus for providing virtual content over a network

Computerized network apparatus configured to provide digitally rendered content to a computerized client device within a content distribution network, the computerized network apparatus comprising:

• digital processor apparatus;
• network interface apparatus in data communication with the digital processor apparatus;
• and
• storage apparatus in data communication with the digital processor apparatus, the storage apparatus comprising at least one computer program configured to, when executed on the digital processor apparatus, cause the computerized network apparatus to:
• cause storage of encoded digital content at first storage location of a computerized storage entity;
• cause transmission of the encoded digital content to the computerized client device, the computerized client device associated with at least one user and comprising an application computer program configured to execute on the computerized client device at least after decode of at least a portion of the encoded digital content, the application computer program configured to enable the at least one user to indicate one or more locations within the decoded digital content with marker data wherein at least one of an addition to, deletion from, or modification of, the digital content is to be performed, and generate one or more data structures comprising at least the marker data;
• receive at least one of the one or more data structures, the one or more data structure having been uploaded by the computerized client device;
• cause storage of the received at least one data structure at a second location of the computerized storage entity of the content distribution network, the second location comprising a separate storage location from the first storage location;
• based at least on the received at least one data structure, cause application of the at least one of the addition, deletion or modification to the encoded digital content to generate a version of the encoded digital content implementing the at least one of the addition, deletion or modification, wherein the application of the at least one of the addition, deletion or modification to the encoded digital content is not performed until data representative of a request to access the version of the encoded digital content is received;
• and
• cause delivery of the version of the encoded digital content to the computerized client device.

Computer readable apparatus comprising a non-transitory storage medium, the non-transitory storage medium comprising at least one computer program having a plurality of instructions, the plurality of instructions configured to, when executed on a digital processing apparatus of a computerized network apparatus of a content distribution network, cause the computerized network apparatus to:

• cause storage of encoded digital content at first storage location of a computerized storage entity;
• cause transmission of the encoded digital content to the computerized client device, the computerized client device associated with at least one user, the computerized client device comprising an application computer program congfigured to execute on the computerized client device at least after decode of the encoded digital content and enable designation by a user of the computerized client device of one or more locations within the decoded digital content with marker data indicative of where at least one of an addition to, deletion from, or modification of the digital content is to be performed, the client device further configured to generate a data structure, the data structure comprising at least the marker data;
• receive the data structure, the data structure having been uploaded by the computerized client device;
• cause storage of the data structure at a second location of the computerized storage entity of the content distribution network, the second location comprising a separate storage location from the first storage location;
• based at least on the data structure, apply the at least one of the addition, deletion or modification to the digital content to generate a version of the encoded digital content implementing the at least one of the addition, deletion or modification to the encoded digital content, wherein the application of the at least one of the addition, deletion or modification to the encoded digital content is not performed until data representative of a request to access the version of the encoded digital content is received;
• and
• cause delivery of the version of the encoded digital content to the computerized client device.
