Abstract: A digital television transmitting system includes a frame encoder, a block processor, a group formatter, and a multiplexer. The frame encoder forms an enhanced data frame and encodes the data frame for error correction and for error detection. The block processor further encodes the encoded data frame at a rate of 1/2 or 1/4, and the group formatter divides the encoded data frame into a plurality of enhanced data blocks and maps the divided data blocks into a plurality of enhanced data groups, respectively. The multiplexer multiplexes the enhanced data groups with main data.

Abstract: A DTV transmitter includes a pre-processor expanding original enhanced data, a data formatter generating enhanced data packets including the expanded enhanced data and inserting known data place holders into the data packets, a multiplexer multiplexing the enhanced data packets with main data packets including main data, and an RS encoder adding systematic RS parity data to each main data packet and adding non-systematic RS parity data holders to each enhanced data packet. It further includes a data interleaver interleaving the RS-coded data packets, a known data generator generating know data symbols, a converter converting the interleaved data packet into symbols, and a symbol processor processing the converted symbols. The symbol processor removes symbols representing the null data, encodes symbols representing the original enhanced data at a rate of N/M, and replaces symbols representing the know data place holders with known data symbols.

Abstract: An air inlet assembly for circulating air in a receiving space for receiving laundry, and a laundry treatment apparatus including the same are provided. An air inlet assembly according to an aspect of the present disclosure includes a cover mounted on an air suction part, wherein the air suction part includes a through-hole formed in a portion thereof. The cover includes a base plate configured to cover the air suction part when viewed in a plan view, by forming a portion corresponding to the through-hole as an opened plate shape, an outer wall configured to continuously protrude along the periphery of the base plate, and a rib configured to protrude from an inner portion spaced apart from the outer wall so as to form a water discharge channel in a space between the outer wall and the rib, wherein the water discharge channel extends to the through-hole.

Abstract: A transmitting system and method therein are disclosed, by which mobile service data is received and processed. The transmitting system includes an encoder, a signaling encoder, a group formatter, a transmission unit. The encoder encodes mobile data and the signaling encoder encodes signaling information. The group formatter forms data groups having the encoded mobile and signaling information. The data groups have a plurality of data blocks and specific data blocks of the plurality of data blocks include known data sequences. The transmission unit transmit broadcast signal including a parade that includes a collection of data groups having same FEC parameters. And the signaling information includes information identifying the parade and first assigned data group number for the parade to which a first assigned data group belongs.
