Abstract

A media device allows users to watch and capture portions from a media stream. Users may then share the captured media content with other users. In one embodiment, the media device receives a media stream, plays the media stream, and caches a portion of the media stream as it is being played. A user can define a media clip by selecting its boundaries in the cached portion of the media stream. The media device creates the media clip based on the user'"'"'s input and enables the user to transmit the media clip to another system, such as a community website for sharing it with other users.

Claims

1. A computer-implemented method for sharing media content from a first device over a digital network, the method comprising:

receiving a media stream at the first device from a remotely-located media source;

receiving user commands that define a portion of the received media stream bounded by a start point and an end point;

responsive to receiving the user commands, capturing the defined portion of the received media stream that is bounded by the start point and the end point to thereby create a clip from the; and

transmitting the clip to a second device via the digital network.

2. The method of claim 1 further comprising receiving metadata associated with the media stream that defines a limited duration for clips created from particular programming contained within the media stream.

3. The method of claim 2 wherein the metadata is received with the media stream from the remote source.

4. The method of claim 2 further comprising preventing the clip from exceeding the limited duration defined in the metadata for the particular programming contained within the media stream.

5. The method of claim 1 further comprising receiving a subsequent user input that identifies a representative video frame that represents the clip, and associating the clip with the representative video frame prior to transmitting the clip to the second device via the network.

6. The method of claim 1, further comprising:

receiving information that describes the content of the clip; and

associating the information with the clip.

7. The method of claim 6, wherein the information is received at least in part from a user input.

8. The method of claim 6, wherein the information is received at least in part from an automatic process for obtaining information about the clip.

9. The method of claim 6, wherein the information is received at least in part by extracting metadata embedded in the media stream.

10. The method of claim 6, wherein the information is obtained at least in part from electronic programming guide data received from the remotely-located media source.

11. The method of claim 1, wherein the transmitting of the clip comprises uploading the clip to a media content sharing website.

12. The method of claim 1 wherein transmitting of the clip comprises sending an email containing the clip to a selected recipient.

13. The method of claim 1 further comprising caching at least a portion of the received media stream at the first device and playing the media stream from the cached portion of the media stream, and wherein the captured portion of the media stream used to create the clip is obtained from the same cached portion of the media stream used to play the media stream.

14. A computer program product for sharing media content from a first device to a second device, the computer program product comprising a non-transitory computer-readable storage medium containing computer program code for performing a method comprising:

receiving a media stream at the first device from a remotely-located media source;

receiving user commands that define a portion of the received media stream bounded by a start point and an end point;

responsive to receiving the user commands, capturing the defined portion of the received media stream that is bounded by the start point and the end point to thereby create a clip of the defined portion of the received media stream; and

transmitting the clip of the defined portion of the received media stream to a second device via the digital network.

15. The computer program product of claim 14 wherein the media stream is a digital media stream transmitted over the digital network from a placeshifting device that is configured to receive a television signal from a source, to convert the television signal to the media stream, and to transmit the media stream on the digital network.

16. The computer program product of claim 14 wherein the media stream is a broadcast television signal.

17. A media device comprising:

an interface to a digital network;

a cache configured to temporarily store at least a portion of a media stream as the media stream is received from a remotely-located media source; and

a processor configured to output the cached portion of the media stream for presentation on a display as the media stream is received, to receive user commands that define a portion of the received media stream bounded by a start point and an end point while the cached portion of the media stream is being output for presentation, to create a clip of the defined portion of the media stream by copying data from the cached portion of the media stream, and to transmit the clip to a second device via the digital network.

18. The media device of claim 17 wherein the media stream is received via the interface to the digital network from a remotely-located placeshifting device.

19. The media device of claim 17 wherein the media stream contained within a broadcast television signal received at the media device.

20. The media device of claim 17 further comprising a remote control interface, and wherein the user commands that define the portion of the received media stream bounded by the start point and the end point are received from a remote control via the remote control interface.
