Abstract

Content intended for delivery to one or more consuming users may be recorded by a content distribution system. The recording or archival of the content may allow users to retrieve the content at a later time without providing specific instructions to record the content. Storage of the content may include retrieving programming information describing the content and storing the information in association with the content. In one or more arrangements, descriptive data for content may be generated based on user feedback. Additionally or alternatively, content storage may include fragmentation of the content into a number of segments or segments of a specified size. Content may further be paused and resumed between multiple devices, taking into account the capabilities and compatibilities of the devices and a network through which the content is to be delivered.

Claims

1. A method comprising:

delivering, by a computing system, content to one or more user devices of a plurality of user devices connected to a network during a first delivery process; and

storing, by the computing system while delivering the content during the first delivery process, a copy of the content to a storage device, wherein the storage device and the computing system are located remotely from the one or more user devices of the plurality of user devices, wherein the storing is performed irrespective of any interaction with or input received from any of the plurality of user devices,

wherein the storing of the copy of the content is separate from the first delivery process, and comprises;

fragmenting the content into a plurality of segments, each segment being of a predefined size; and

storing, as the copy of the content, each of the plurality of segments as a separate content segment file.

2. The method of claim 1, wherein storing the copy of the content to the storage device further comprises:

retrieving supplemental information comprising content attribute information from a source other than the content; and

storing the content attribute information in association with the copy of the content.

3. The method of claim 2, wherein the content is received from a content source and the content attribute information is retrieved from an electronic programming guide, the method further comprising:

receiving, by the computing system, a request for the stored copy of the content after the first delivery process;

identifying the stored copy of the content in the storage device based on the retrieved content attribute information; and

delivering the stored copy of the content to a requesting device in a second delivery process.

4. The method of claim 1, wherein storing the copy of the content to the storage device further comprises storing each of the plurality of segments as individually user-retrievable content items in the storage device.

5. The method of claim 1, further comprising:

receiving, by the computing system during or after the first delivery process, user identification of a start time and an end time of an event in the content from the one or more user devices, the event being less than an entirety of the content;

receiving, by the computing system, information describing the event;

identifying one or more of the plurality of segments of the content corresponding to a period of time between the user-identified start time and the user-identified end time of the event; and

storing the information describing the event in association with the identified one or more plurality of segments corresponding to the period of time between the user-identified start and end times.

6. The method of claim 1, further comprising identifying, from one or more external content repositories, at least a portion of the content using one or more time codes specified in a content segment file.

7. The method of claim 1, further comprising scheduling retrieval availability of the stored copy of the content to one or more users during a second delivery process for a future date and time, wherein the future date and time is defined based on an amount of time from storing the copy of the content to the storage device.

8. The method of claim 1, further comprising:

receiving, during the first delivery process, user feedback relating to the content;

identifying a segment of the plurality of segments corresponding to a time at which the user feedback was received; and

storing the user feedback in association with the identified segment.

9. The method of claim 1, further comprising:

storing, in the storage device, a first version of the copy of the content and a second version of the copy of the content, wherein the first version is different from the second version; and

storing, in the storage device, a reference between a segment of the first version of the copy of the content and a corresponding one or more segments of the second version of the copy of the content.

10. The method of claim 9, wherein the first version corresponds to a first video quality and the second version corresponds to a second video quality,

wherein the segment of the first version corresponds to a plurality of segments of the second version, and

wherein the reference links the segment of the first version to the corresponding plurality of segments of the second version.

11. An apparatus comprising:

at least one processor; and

memory coupled to the at least one processor and storing computer readable instructions that, when executed, cause the apparatus to;

deliver content to one or more user devices of a plurality of user devices connected to a network during a delivery process; and

store, during the delivery process, a copy of the content to a storage device, wherein the storage device and the apparatus are located remotely from one or more user devices of the plurality of user devices, wherein the storing is performed irrespective of any interaction with or input received from any of the plurality of user devices, wherein storing the copy of the content is separate from the delivery process and comprises;

fragmenting the content into a plurality of segments, each of the segments being of a predefined size; and

storing, as the copy of the content, each of the plurality of segments as a separate content segment file.

12. The apparatus of claim 11, wherein storing the copy of the content to the storage device further comprises:

retrieving content attribute information; and

storing the content attribute information in association with the copy of the content.

13. The apparatus of claim 12, wherein the computer readable instructions, when executed, further cause the apparatus to:

receiving a request for the stored copy of the content;

identifying the stored copy of the content in the storage device based on the content attribute information; and

delivering the stored copy of the content to a requesting device.

14. The apparatus of claim 11, wherein storing the copy of the content to the storage device further comprises storing each of the plurality of segments as individually retrievable content items in the storage device.

15. The apparatus of claim 11, wherein the computer readable instructions, when executed, further cause the apparatus to:

receive, during or after the delivery process, user identification of a start time and an end time of an event in the content from the one or more user devices, the event being less than an entirety of the content;

receive information describing the event;

identify one or more of the plurality of segments of the content corresponding to a period of time between the user-identified start time and the user-identified end time; and

store the information describing the event in association with the identified one or more plurality of segments corresponding to the period of time between the user-identified start and end times.

16. The apparatus of claim 15, wherein receiving the information describing the event further comprises receiving user specified data.
