A transmitter, according to one embodiment of the present invention, comprises: a data encoder for generating a segment which transmits a portion of data included in a media; a packet encoder for generating a packet which divides the segment into one or more data units, and includes a payload which comprises a header and all or a portion of the data of the data unit; and a broadcast signal transmitting unit for generating a broadcast signal which includes the packet, and transmitting the broadcast signal, wherein the header includes a transport object identifier (TOI) element, and the TOI c elementomprises a data unit identification element which identifies the data unit, and a segment identification element which identifies the segment including the data transmitted in the payload.

Method and apparatus for transmitting/receiving broadcast signal

A housing (3) for a fan (1) forms an impeller space (6) for rotationally accommodating an impeller (2) rotatable about a rotation axis (A), an air intake opening (20) in direct communication with the impeller space (6), an exhaust opening (21) for an air-gas mixture, a gas inlet opening (25) spaced apart from the air intake opening (20) and in direct communication with the impeller space (6), so that the impeller space (6) forms a space for mixing an air flow (31) from the air intake opening (20) with a gas flow (32) from the gas inlet opening (25).
