Abstract

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.
