Content server media stream management
Mechanisms are provided to manage media stream transmissions at a content server. A content server detects that a user on a device such as a mobile device has stopped playing a live media stream. The content server maintains information associating the user with the media stream and time information. When the content server detects that a user wishes to resume playing a media stream, the user can continue viewing the media stream from where stoppage occurred. In many instances, the content server stores many hours of live media stream data and allows a user to select a particular starting point.
1. A method comprising:
maintaining a plurality of channel buffers at a content server;
transmitting a first media stream to a first device beginning with packets having timestamps corresponding to a first position;
receiving a stop request for the first media stream from the first device, wherein the first media stream continues to buffer at the content server even after receiving the stop request from the first device such that a user may resume the first media stream at a later time without missing portions of the first media stream;
receiving a resume request for resuming playback of the first media stream from a second device, the second request identifying a second position in the first media stream; and
transmitting the first media stream or a second media stream, wherein the resolution of the first media stream is different from the resolution of the second media stream, to the second device beginning with packets having timestamps corresponding to the second position, wherein the second media stream is transmitted if the second device cannot play the first media stream, and
wherein either the first device is a mobile device and the second device is not a mobile device, or the second device is a mobile device and the first device is not a mobile device.
2. The method of claim 1 , wherein transmitting the first media stream is performed in response to a request to establish a session from the from the first device.
3. The method of claim 1 , wherein information at the content server is maintained after an indication that the first media stream is no longer being played is received.
4. The method of claim 1 , wherein the first device is a mobile device and the second device is a set-top box.
5. The method of claim 1 , wherein the first device is a mobile device and the second device is a computer system.
6. A content server comprising:
a plurality of channel buffers;
a processor; and
memory storing instructions to execute a method, the method comprising:
maintaining the plurality of channel buffers at the content server;
transmitting a first media stream to a first device beginning with packets having timestamps corresponding to a first position;
receiving a stop request for the first media stream from the first device, wherein the first media stream continues to buffer at the content server even after receiving the stop request from the first device such that a user may resume the first media stream at a later time without missing portions of the first media stream;
receiving a resume request for resuming playback of the first media stream from a second device, the second request identifying a second position in the first media stream; and transmitting the first media stream or a second media stream, wherein the resolution of the first media stream is different from the resolution of the second media stream, to the second device beginning with packets having timestamps corresponding to the second position, wherein the second media stream is transmitted if the second device cannot play the first media stream, and
wherein either the first device is a mobile device and the second device is not a mobile device, or the second device is a mobile device and the first device is not a mobile device.
7. The content server of claim 6 , wherein transmitting the first media stream is performed in response to a request to establish a session from the from the first device.
8. The content server of claim 6 , wherein information at the content server is maintained after an indication that the first media stream is no longer being played is received.
9. The content server of claim 6 , wherein the first device is a mobile device and the second device is a set-top box.
10. The content server of claim 6 , wherein the first device is a mobile device and the second device is a computer system.
11. A non-transitory computer readable medium comprising instructions to execute a method, the method comprising:
maintaining a plurality of channel buffers at a content server;
transmitting a first media stream to a first device beginning with packets having timestamps corresponding to a first position;
receiving a stop request for the first media stream from the first device, wherein the first media stream continues to buffer at the content server even after receiving the stop request from the first device such that a user may resume the first media stream at a later time without missing portions of the first media stream;
receiving a resume request for resuming playback of the first media stream from a second device, the second request identifying a second position in the first media stream; and
transmitting the first media stream or a second media stream, wherein the resolution of the first media stream is different from the resolution of the second media stream, to the second device beginning with packets having timestamps corresponding to the second position, wherein the second media stream is transmitted if the second device cannot play the first media stream, and
wherein either the first device is a mobile device and the second device is not a mobile device, or the second device is a mobile device and the first device is not a mobile device.
12. The non-transitory computer readable medium of claim 11 , wherein transmitting the first media stream is performed in response to a request to establish a session from the from the first device.
13. The non-transitory computer readable medium of claim 11 , wherein information at the content server is maintained after an indication that the first media stream is no longer being played is received.
14. The non-transitory computer readable medium of claim 11 , wherein the first device is a mobile device and the second device is a set-top box or a computer system.
