Abstract

Systems and methods are described herein for a receiver device transitioning between networks during ultra-low latency streaming with minimal user experience impact. Such systems and methods avoid dropping packets of streamed content and do not require expensive and time-consuming retransmission techniques or instantaneous decoder refresh repair. The disclosed techniques may receive packets of a content stream via a first network and first receiver instance. The disclosed techniques may additionally identify an indication to switch to a second network and receive packets of the content streams via both a first network and a second network. The disclosed techniques may further identify that the received packets across both the first network and the second network are synchronized, terminate execution of the first receiver instance, and continue to receive packets of the content stream via only the second network.

Claims21

Dependent claims

A method comprising:

receiving, from a sender device, a first one or more packets of a content stream by a first receiver instance executing on a receiver device for processing data received via a first network of a first network type;
identifying an indication to attempt to switch from receiving the content stream via the first network to receiving the content stream via a second network of a second network type;
based at least in part on the identifying the indication:
instantiating a second receiver instance on the receiver device for processing data received via the second network;
receiving, from the sender device:
a second one or more packets of the content stream by the first receiver instance;
a third one or more packets of the content stream by the second receiver instance, wherein the second one or more packets and the third one or more packets represent the same data of a portion of the content stream;
based at least in part on determining that the second one or more packets received by the first receiver instance are synchronized with the third one or more packets received by the second receiver instance:
terminating execution of the first receiver instance on the receiver device;
and
receiving a fourth one or more packets of the content stream by the second receiver instance.

8 more elements

A system comprising:

input/output circuitry, wherein the input/output circuitry is configured to:
receive, from a sender device, a first one or more packets of a content stream by a first receiver instance executing on a receiver device for processing data received via a first network of a first network type;
and
control circuitry, wherein the control circuitry is configured to:
identify an indication to attempt to switch from receiving the content stream via the first network to receiving the content stream via a second network of a second network type;
based at least in part on the identifying the indication:
instantiate a second receiver instance on the receiver device for processing data received via the second network;
and
wherein the input/output circuitry is further configured to:
receive, from the sender device:
a second one or more packets of the content stream by the first receiver instance;
a third one or more packets of the content stream by the second receiver instance, wherein the second one or more packets and the third one or more packets represent the same data of a portion of the content stream;
and
wherein the control circuitry is further configured to:
based at least in part on determining that the second one or more packets received by the first receiver instance are synchronized with the third one or more packets received by the second receiver instance:
terminate execution of the first receiver instance on the receiver device;
and
wherein the input/output circuitry is further configured to:
receive a fourth one or more packets of the content stream by the second receiver instance.
