Abstract

A method, performed by a computer device, may include determining one or more frequently watched television channels associated with a customer's account. The method may further include obtaining content associated with the one or more frequently watched television channels via multicast transmission units from a video serving office associated with a television services provider; converting the multicast transmission units into video segments playable by a media playing device; storing the video segments in a cache associated with the computer device; detecting a selection of a television channel associated with the obtained content made via the media playing device; and providing the stored video segments to the media playing device, in response to detecting the selection of the television channel associated with the obtained content.

First claim

What is claimed is:

1. A method, performed by a computer device, the method comprising:
determining, by the computer device, one or more frequently watched television channels associated with a customer's account;
obtaining, by the computer device, content associated with the one or more frequently watched television channels via multicast transmission units from a video serving office associated with a television services provider, wherein the multicast transmission units include User Datagram Protocol (UDP) Maximum Transmission Units (MTUs);
converting, by the computer device, the multicast transmission units into video segments playable by a media playing device, wherein the video segments playable by the media playing device include Moving Picture Experts Group (MPEG) Dynamic Adaptive Streaming over Hypertext Transfer Protocol (DASH) video segments or Hypertext Transfer Protocol Live Streaming (HLS) video segments;
storing, by the computer device, the video segments in a cache associated with the computer device;
detecting, by the computer device, a selection of a television channel associated with the obtained content made via the media playing device; and
providing, by the computer device, the stored video segments to the media playing device, in response to detecting the selection of the television channel associated with the obtained content, wherein the provided video segments are treated by the media playing device as if being received from the video serving office, and wherein the computer device is configured to function as a customer premises switch or router.

2. The method of claim 1 , wherein the video segments stored in the cache for the television channel include at least the past three days of content for the television channel, the method further comprising:
receiving, from the media playing device, a request to view content for the television channel that was broadcast at a particular time during the past three days; and
providing the requested content for the television channel to the media playing device.

3. The method of claim 1 , further comprising:
receiving, from the media playing device, a trick mode command, wherein the trick mode command includes at least one of a pause command, a play command, a rewind command, or a fast forward command; and
executing the trick mode command with respect to the stored video segments provided to the media playing device.

4. The method of claim 1 , wherein the video segments stored in the cache are encrypted, and wherein the media playing device performs authentication and decryption on the video segments to play the video segments.

5. The method of claim 1 , wherein determining the one or more frequently watched television channels associated with the customer's account includes:
receiving, from a user associated with the customer's account, a selection of the one or more frequently watched television channels as channels to store in the cache.

6. The method of claim 1 , further comprising:
detecting a faulty or missing video segments among the stored video segments;
requesting a replacement video segment from the video serving office; and
storing the replacement video segment in the cache.

7. The method of claim 1 , further comprising:
receiving updated content associated with the television channel via multicast transmission units from the video serving office;
converting the multicast transmission units associated with the updated content into updated video segments; and
storing the updated video segments in the cache.

8. The method of claim 1 , wherein the media playing device includes:
a set-top box;
a smart television;
a High Definition Multimedia Interface (HDMI) dongle media device;
a game console; or
a mobile communication device.

9. The method of claim 1 , wherein the computer device includes a broadband router and wherein the cache includes at least one terabyte of storage capacity.

10. A computer device comprising:
logic configured to:
determine one or more frequently watched television channels associated with a customer's account;
obtain content associated with the one or more frequently watched television channels via multicast transmission units from a video serving office associated with a provider of television services, wherein the multicast transmission units include User Datagram Protocol (UDP) Maximum Transmission Units (MTUs);
convert the multicast transmission units into video segments playable by a media playing device, wherein the video segments playable by the media playing device include Moving Picture Experts Group (MPEG) Dynamic Adaptive Streaming over Hypertext Transfer Protocol (DASH) video segments or Hypertext Transfer Protocol Live Streaming (HLS) video segments;
store the video segments in a cache associated with the computer device;
detect a selection of a television channel associated with the obtained content made via the media playing device; and
provide the stored video segments to the media playing device, in response to detecting the selection of the television channel associated with the obtained content, wherein the provided video segments are treated by the media playing device as if being received from the video serving office, and wherein the computer device is configured to function as a customer premises switch or router.

11. The computer device of claim 10 , wherein the video segments stored in the cache for the television channel include at least three days of content for the television channel, and wherein the logic is further configured to:
receive, from the media playing device, a request to view content for the television channel that was broadcast at a particular time during the three days; and
provide the requested content for the television channel to the media playing device.

12. The computer device of claim 10 , wherein the logic is further configured to:
receive, from the media playing device, a trick mode command, wherein the trick mode command includes at least one of a pause command, a play command, a rewind command, or a fast forward command; and
execute the trick mode command with respect to the stored video segments provided to the media playing device.

13. The computer device of claim 10 , wherein the logic is further configured to:
receive updated content associated with the television channel via multicast transmission units from the video serving office;
convert the multicast transmission units associated with the updated content into updated video segments; and
store the updated video segments in the cache.

14. The computer device of claim 10 , wherein the logic is further configured to:
determine that the customer's account is associated with a channel surfing habit; and
request channel snapshots via a multicast join request, in response to determining that the customer's account is associated with a channel surfing habit.

15. A computer-readable memory device storing instructions executable by one or more processors, the computer-readable memory device comprising:
one or more instructions to determine one or more frequently watched television channels associated with a customer's account;
one or more instructions to obtain content associated with the one or more frequently watched television channels via multicast transmission units from a video serving office associated with a provider of television services, wherein the multicast transmission units include User Datagram Protocol (UDP) Maximum Transmission Units (MTUs);
one or more instructions to convert the multicast transmission units into video segments playable by a
