Abstract

Content recordation techniques are described. In an implementation, a method includes querying electronic program guide (EPG) data to determine if a content item described in a recording document is available for recording. If the content item is available, a reference is added to a recording list for causing recordation of the content item.

Claims

1. A method comprising:

receiving a recording document via a network that describes a content item but does not describe whether the content item is available for recording or how the content item is to be recorded, wherein the recording document was generated by a recording module configured to examine a textual description of the content item to locate one or more words that describe the content item and dynamically generate the recording document, wherein the recording document includes the located one or more words from the textual description;

querying electronic program guide (EPG) data to determine if the content item described in the recording document is available for recording without user intervention, and if so, how the content item is to be recorded;

examining client state data that describes conditional access rights of a client to determine if recordation of the content item for the client is permitted using digital rights management; and

if the content item is available and recordation is permitted, adding a reference in a recording list for causing recordation of the content item without user intervention.

2. A method as described in claim 1, wherein the querying is performed by execution of a parser module on a head end.

3. A method as described in claim 1, wherein:

the querying is performed by execution of a parser module on a head end; and

the reference in the recording list is for causing recordation of the content item by a client.

4. A method as described in claim 1, wherein the querying is performed by execution of a parser module on a client.

5. A method as described in claim 1, wherein:

the query is performed at a client; and

the reference in the recording list is for causing recordation of the content item at a head end.

6. A method as described in claim 1, further comprising determining if the available content item conflicts with another content item in the recording list.

7. A method as described in claim 1, wherein the recording document describes the content item through at least one of a restrictive criterion, a service, a time, or a genre.

8. A method as described in claim 1, wherein the textual description is selected from the group consisting of:

one or more words entered by a user via a user interface;

an article;

a text message;

an email; and

another content item.

9. A computer-implemented method comprising:

examining, by a recording module, a textual description of a content item to locate one or more words that describe the content item;

dynamically generating, by the recording module, a recording document that includes the located one or more words;

comparing the one or more words in the generated recording document with electronic program guide (EPG) data to determine if the content item is available for recording; and

if the content item is available, adding a reference in a recording list to cause recordation of the content item.

10. A computer-implemented method as described in claim 9, wherein the content item is selected from the group consisting of:

a television program;

a movie;

a picture;

a music file; and

media.

11. A computer-implemented method as described in claim 9, wherein:

the examining is performed by executing a recording module on a client; and

the comparing and the adding are performed by executing a parser module on a head end.

12. A computer-implemented method as described in claim 9, wherein the examining, the comparing, and the adding are performed by executing a recording module and a parser module on a client.

13. A computer-implemented method as described in claim 9, further comprising:

communicating the recording document to a head end which executes a parser module to perform the comparing and the adding; and

communicating the recording list to a client to cause recordation of the content item described in the EPG data through execution of a navigation module on the client.

14. A computer-implemented method as described in claim 9, further comprising determining if the client is authorized to record the content item.

15. A computer implemented method as described in claim 14, wherein the determining is performed at a head end using client state data that is stored on the head end.

16. One or more computer readable memory devices comprising computer executable instructions that, when executed by a computer, direct the computer to:

examine, by a recording module, a textual description of a content item to locate one or more words that describe the content item;

dynamically generate, by the recording module, a recording document having the located one or more words; and

form a communication for communicating the recording document for comparison with electronic program guide (EPG) data to determine if the content item described by the recording document is available for recording, and if so, how the content item is to be recorded.

17. One or more computer readable memory devices as described in claim 16, wherein the computer executable instructions further direct the computer to:

determine if the content item described by the recording document is available for recording; and

if the content item is available, add a reference to the available content item to a recording list.

18. One or more computer readable memory devices as described in claim 16, wherein the computer executable instructions further direct the computer to examine client state data that describes conditional access rights of a plurality of clients to determine if recordation of the content item for a particular said client is permitted.

19. One or more computer readable memory devices as described in claim 16, wherein the computer executable instructions further direct the computer to determine if the available content item conflicts with another content item in a recording list.

20. One or more computer readable memory devices as described in claim 16, wherein the textual description is selected from the group consisting of:

one or more words entered by a user via a user interface;

an article;

a text message;

an email; and

another content item.

21. A head end comprising:

a processor; and

memory configured to maintain;

electronic program guide (EPG) data;

a recording document having a plurality of elements which describe a content item, wherein the recording document was generated by a recording module configured to examine a textual description of the content item to locate one or more words that describe the content item and dynamically generate the recording document, wherein the recording document includes the located one or more words; and

a parser module that is executable on the processor without user intervention to;

determine if the content item described in the recording document is available for recording by comparing at least one said element with the electronic program guide (EPG) data;

examine client state data that describes conditional access rights of a plurality of clients to determine if recordation of the content item for a particular said client is permitted based on one or more parental blocks; and

if the content item is available and recordation of the content item for the particular said client is permitted, add a reference to a recording list describing how the content item is to be recorded for causing recordation of the content item in the memory for access by the particular said client.
