Latency Reduction by Sending Audio and Metadata Ahead of Time

Latency reduction by sending audio and metadata ahead of time may be provided. First, an encoder may receive a source. Next, the encoder may create a transport stream from the source. The transport stream may comprise a plurality of first data units and a plurality of second data units. The plurality of second data units may respectively correspond to the plurality of first data units. The plurality of first data units are preceded in time in the transport stream by their respective corresponding ones of the plurality of second data units. A packager may then receive the transport stream and package data chunks from the transport stream.
