Abstract
There is provided a method for adaptive bitrate (ABR) adjustments in an IP network before making upshift of ABR level of media streams like video for live Over the Top (OTT) distribution. Example methods may include initiating, at a first time interval, probing of the IP network to determine if a first candidate bitrate is applicable, where the first candidate bitrate is greater than a preset bitrate of a client device data stream, determining that the candidate bitrate is applicable, increasing a transfer bitrate of the client device data stream, and initiating, at a second time interval, probing of the IP network to determine if a second candidate bitrate is applicable, where the second candidate bitrate is greater than the first candidate bitrate.
Claims20
A method for adaptive bitrate (ABR) adjustments in an Internet Protocol (IP) network comprising:
- initiating, at a first time interval, probing of the IP network to determine if a first candidate bitrate is applicable, wherein the first candidate bitrate is greater than a preset bitrate of a client device data stream;
- determining that the candidate bitrate is applicable;
- increasing a transfer bitrate of the client device data stream;
- and
- initiating, at a second time interval, probing of the IP network to determine if a second candidate bitrate is applicable, wherein the second candidate bitrate is greater than the first candidate bitrate.
A system comprising:
- memory configured to store computer-executable instructions;
- and
- at least one computer processor configured to access the memory and execute the computer-executable instructions to:
- initiate, at a first time interval, probing of an IP network to determine if a first candidate bitrate is applicable, wherein the first candidate bitrate is greater than a preset bitrate of a client device data stream;
- determine that the candidate bitrate is applicable;
- increase a transfer bitrate of the client device data stream;
- and
- initiate, at a second time interval, probing of the IP network to determine if a second candidate bitrate is applicable, wherein the second candidate bitrate is greater than the first candidate bitrate.
