Abstract
A content streaming system and methodology for facilitating the management of content streaming. A content delivery service receives at least an original content stream and multiple input contents from an original content provider. Additionally, the content delivery service processes the received input content streams, buffers the original and supplemental input content streams, and switches between the available input content streams for seamless and fast broadcasting. The decision to switch between a second content and a third is determined by an indication that a third input content is available in the buffer.
Claims22
A system to manage input content comprising:
- one or more computing devices associated with a set of available original content provider computing devices, wherein at least a portion of the original content provider computing devices are configured to provide a plurality of input content streams to a content delivery service and notifications for switching between input content streams;
- one or more computing devices associated with a scheduler component of the content delivery service, wherein the scheduler component is configured to:
- receive a first original input content stream from the plurality of input content streams provided by the original content provider computing devices;
- process the first original input content stream for transmission, wherein processing the first original input content stream for transmission includes storing at least a portion of the first original input content stream in a first buffer and making the buffered first original input content available for transmission;
- receive a second input content stream from the plurality of input content streams provided by the original content provider computing devices;
- obtain a first notification from the original content provider computing device to switch to the second input content stream;
- process the second input content stream for transmission, wherein processing the original input content stream for transmission includes storing at least a portion of the second original input content stream in in a second buffer;
- responsive to the obtained first notification and storing of the at least a portion of the second original input content stream in the second buffer, make the second input content in the second buffer available for transmission;
- receive a third input content stream from the plurality of input content streams provided by the original content provider computing devices;
- obtain a second notification from the original content provider computing device to switch to the third input content stream;
- process the third input content stream for transmission, wherein processing includes determining that the first input content in the first buffer and the second input content in the second buffer is still available for transmission and storing at least a portion of the third original input content stream in a third buffer, wherein the first, second and third buffers are different;
- and
- responsive to the obtained second notification and storing of the at least a portion of the third original input content stream in the third buffer, make the third input content in the third buffer seamlessly available for transmission.
10 more elements
A computer-implemented method to manage input content streaming comprising:
- receiving, by at least one computing device of a content delivery service, two content streams from original content provider computing devices;
- receiving, by the at least one computing device of the content delivery service, a third input content stream from the original content provider computing devices;
- obtaining, by the at least one computing device of the content delivery service, a notification from the original content provider computing device to switch to the third input content stream;
- processing, by the at least one computing device of the content delivery service, the third input content stream for transmission, wherein processing includes determining that buffers from the two content streams from the original content provider computing devices are not available;
- storing at least a portion of the third original input content stream in a third buffer based at least in part on the determining that the buffers from the two content streams are not available;
- and
- responsive to the obtained notification and storing of the at least a portion of the third original input content stream in the third buffer, making, by the at least one computing device of the content delivery service, the third input content in the third buffer available for transmission to a client device.
4 more elements
A computer-implemented method to manage seamless transmission of input content streaming comprising:
- receiving, by at least one computing device of a content delivery service, a first primary content stream and a first supplemental content stream from original content provider computing devices;
- processing, by the at least one computing device of the content delivery service, the first primary content stream and the first supplemental content stream to make the content available for transmission to a client device;
- obtaining, by the at least one computing device of the content delivery service, a notification from the original content provider computing device to switch to an additional supplemental content stream;
- processing, by the at least one computing device of the content delivery service, the additional supplemental content stream for transmission, wherein processing includes determining that buffers from the first primary content stream and the first supplemental content stream are in use;
- storing at least a portion of the additional supplemental content stream in a third buffer based at least in part on the determining that the buffers from the two content streams are not available;
- and
- responsive to the obtained notification and storing of the at least a portion of the additional supplemental content in the third buffer, seamlessly making, by the at least one computing device of the content delivery service, the additional supplemental content in the third buffer available for transmission to the client device.
