Systems and methods are disclosed herein for optimizing bandwidth for broadcast transmission. The disclosed techniques herein provide for receiving first and second content for transmission to subscriber devices on a first and second channels. The system then determines whether the first and second content contain a common segment. If so, the system updates metadata schema (e.g., homogeneous channel descriptor, homogeneous switch descriptor) to indicate there is a common segment. The system may generate a transport stream during multiplexing of the first and second channels based on the updated metadata schema. The transport stream, for a time duration based on the at least one common segment, includes a first audio feed of the first content and a first video feed of the first content to be provided on the second channel. The system then transmits the transport stream to the one or more subscriber devices.
