An association with a system timing at the time of transmission is secured without changing a display timing in text information of a subtitle, and a reception side displays the subtitle at an appropriate timing. A packet in which a document of the text information of the subtitle having display timing information is included in a payload is generated and transmitted in synchronization with a sample period. A header of the packet includes a time stamp on a first time axis indicating a start time of the corresponding sample period. The payload of the packet further includes reference time information of a second time axis regarding the display timing associated with the start time of the corresponding sample period.

A content service provider can transmit a plurality of content streams each including audio, video, or audio-video content to a plurality of premises. In addition, the content service provider can transmit one or more command streams, along with the plurality of content streams over a common content distribution network. The one or more command streams may each include a repeating set of premises automation commands. The premises automation commands may be sent to one or more appropriate systems if a user selects a channel associated with the corresponding command stream. Each set of premises automation commands may be configured to instruct a system at a premises to perform a function. The commands may, for example, instruct a lighting system to turn on/off lights, a security system to enter an arm or disarm operational state, a thermostat to adjust its temperature, etc.
