Methods and systems for separate delivery of segments of content items
Systems and methods are described herein for transmitting a content item to a user device using multiple delivery protocols. The system receives, at a content source, a request for the content item from the user device. The system splits a digital stream of the content item into a first video signal and a second video signal. The system then transmits, via a unicast server, the first video signal for the content item to the user device, and transmits, via a multicast server, the second video signal for the content item to the user device. The system then causes for presentation on the user device the first video signal followed by the second video signal. In other embodiments, the system is optimized between the unicast delivery of a content item and a peer-to-peer delivery.
1. A method for dynamically optimizing delivery of a content item to a user device, comprising:
receiving, at a content source, a request for the content item from the user device;
splitting, using a demultiplexer, a digital stream into a first video signal of the content item and a second video signal of the content item;
transmitting, via a unicast server, the first video signal for the content item to initiate a presentation of the content item on the user device, wherein the first video signal comprises intraframe segments of the content item;
identifying as transmission servers at least one local device within a proximity of the user device, wherein the at least one local device has received the second video signal of the content item;
transmitting metadata of the transmission servers within the proximity of the user device to the user device;
causing to be transmitted, via a peer-to-peer transmission, the second video signal for the content item from the at least one local device to the user device, wherein the second video signal comprises non-intraframe segments of the content item; and
causing to be presented, on the user device, the first video signal followed by the second video signal.
2. The method of claim 1 , wherein the transmitting, via the unicast server, the first video signal for the content item comprises transmitting the first video signal encrypted with a digital right management (DRM) key for the content item.
3. The method of claim 1 , wherein causing to be transmitted, via the peer-to-peer transmission, the second video signal for the content item comprises causing to be transmitted an unencrypted second video signal for the content item.
4. The method of claim 1 , wherein causing to be presented, on the user device, the first video signal followed by the second video signal comprises switching from presenting the first video signal to presenting the second video signal on the user device.
5. The method of claim 1 , wherein causing to be presented, on the user device, the first video signal followed by the second video signal comprises switching between transmitting the content item via the unicast server and causing to be transmitted the content item via the peer-to-peer transmission.
6. The method of claim 5 , wherein switching between transmitting the content item via the unicast server and causing to be transmitted the content item via the peer-to-peer transmission comprises:
determining that the at least one local device is available;
receiving an indication of the user device receiving the first video signal via the unicast server; and
in response to receiving the indication of the user device receiving the first video signal via the unicast server, causing to be transmitted the second video signal via the peer-to-peer transmission.
7. The method of claim 6 , wherein determining that the at least one local device is available comprises determining that the at least one local device has an available bandwidth.
8. The method of claim 1 , wherein transmitting, via the unicast server, the first video signal comprises delivering the first video signal as a unicast OTT stream to the user device over a cellular network.
9. The method of claim 1 , wherein causing to be transmitted, via the peer-to-peer transmission, the second video signal comprises causing to be transmitted the second video signal via peer-to-peer streaming to the user device.
10. The method of claim 1 , wherein the second video signal for the content item is cached at a content distribution network (CDN) for transmission via the peer-to-peer transmission.
11. A system for dynamically optimizing delivery of a content item to a user device, comprising:
control circuitry configured to:
receive, at a content source, a request for the content item from the user device;
split, using a demultiplexer, a digital stream into a first video signal of the content item and a second video signal of the content item;
transmit, via a unicast server, the first video signal for the content item to initiate a presentation of the content item on the user device, wherein the first video signal comprises intraframe segments of the content item;
identify as transmission servers at least one local device within a proximity of the user device, wherein the at least one local device has received the second video signal of the content item;
transmit metadata of the transmission servers within the proximity of the user device to the user device;
cause to be transmitted, via a peer-to-peer transmission, the second video signal for the content item from the at least one local device to the user device, wherein the second video signal comprises non-intraframe segments of the content item; and
cause to be presented, on the user device, the first video signal followed by the second video signal.
12. The system of claim 11 , wherein the control circuitry is further configured to transmit via the unicast server, the first video signal for the content item by transmitting the first video signal encrypted with a digital right management (DRM) for the content item.
13. The system of claim 11 , wherein the control circuitry is further configured to cause to be transmitted, via the peer-to-peer transmission, the second video signal for the content item by causing to be transmitted an unencrypted second video signal for the content item.
14. The system of claim 11 , wherein the control circuitry is further configured to cause to be presented, on the user device, the first video signal followed by the second video signal by switching from presenting the first video signal to presenting the second video signal on the user device.
15. The system of claim 11 , wherein the control circuitry is further configured to cause to be presented, on the user device, the first video signal followed by the second video signal by switching between transmitting the content item via the unicast server and causing to be transmitted the content item via the peer-to-peer transmission.
16. The system of claim 15 , wherein the control circuitry is further configured to switch between transmitting the content item via the unicast server and causing to be transmitted the content item via the peer-to-peer transmission by:
determining that the at least one local device is available;
receiving an indication of the user device receiving the first video signal via the unicast server; and
in response to receiving the indication of the user device receiving the first video signal via the unicast server, causing to be transmitted the second video signal via the peer-to-peer transmission.
17. The system of claim 16 , wherein the control circuitry is further configured to determine that the at least one local device is available by determining that the at least one local device has an available bandwidth.
18. The system of claim 11 , wherein the control circuitry is further configured to transmit, via the unicast server, the first video signal by delivering the first video signal as a unicast OTT stream to the user device over a cellular network.
19. The system of claim 11 , wherein the control circuitry is further configured to cause to be transmitted, via the peer-to-peer transmission, the second video signal by causing to be transmitted the second video signal via peer-to-peer streaming to the user device.
20. The system of claim 11 , wherein the second video signal for the content item is cached at a content distribution network (CDN) for transmission via the peer-to-peer transmission.
