Transmitting multiple adaptive bit rate (ABR) segment streams on a shared frequency

摘要

A system for transmitting multiple adaptive bit rate (ABR) segment streams on a shared frequency may include an ABR segment generator and transmitter circuitry. The ABR segment generator may encode a content item based at least in part on different ABR profiles to generate encoded streams. The ABR profiles may indicate encoding parameters corresponding to the encoded streams, e.g., bit rates, resolutions, frame rates and/or codecs. The ABR segment generator may be further configured to segment the encoded streams to generate ABR segment streams. The transmitter circuitry may be configured to transmit the ABR segment streams on a shared frequency, such as by transmitting the segment streams over spatially separated antennas, or by applying different orbital angular momentums to the ABR segment streams. In one or more implementations, the system may further include a segment interleaver that is configured to interleave the ABR segment streams.

1. A method for transmitting multiple adaptive bit rate (ABR) segment streams on a shared frequency, the method comprising:
encoding a content item based at least in part on a plurality of ABR profiles to generate a plurality of encoded streams, each of the plurality of encoded streams being encoded differently and each of the plurality of encoded streams corresponding to one of the plurality of ABR profiles; segmenting the plurality of encoded streams to generate a plurality of ABR segment streams, each of the plurality of ABR segment streams corresponding to one of the plurality of encoded streams; and transmitting the plurality of ABR segment streams on the shared frequency to an electronic device irrespective of whether any of the plurality of ABR segment streams have been requested by the electronic device, wherein at least two of the plurality of ABR segment streams are transmitted on the shared frequency to the electronic device simultaneously.
