Abstract: An apparatus and a method for mapping a symbol are provided to symbol-map reliability of information bits and reliability of redundancy bits differently, thereby improving performance. A systematic encoder encodes transmission data(S410). An encoder outputs a plurality of information bits including added redundancy bits. A puncher punches an information bit and a redundancy bit(S420). The puncher punches only the redundancy bit except the information bit. An information interleaver interleaves the punched information bit. The redundancy interleaver interleaves a punched redundancy bit(S430). A symbol mapping device maps the interleaved information bit and the interleaved redundancy bit on symbols respectively(S440).

Abstract: PURPOSE: An apparatus and a method for mapping symbol are provided to improve reception performance by using a different mapping method in retransmission from a mapping method in initial transmission. CONSTITUTION: In a device, transmitted-data is encoded and a plurality of information bits and bits are generated(S410). An information bit and redundancy bit are mapped to a symbol in initial transmission according to a first mapping method(S420). The information bit and redundancy bit are mapped to a symbol in retransmission according to a second mapping method(S450). The second mapping method is different from the first mapping method. The reliability of mapping bit through the first mapping method is different from that of the second mapping method.

Abstract: An electronic picture frame is provided to connect with an external network through a set-top box and a wired and wireless sharing function, perform communication with equipment in a home network through wired and wireless communication technique, and control the equipment at home or remotely. An external communication unit(260) bidirectionally performs the wired or wireless communication of external data contents or an external control signal with the outside of home. An internal communication unit(270) performs the wired or wireless home network communication of internal data contents or an internal control signal with another electronic device in home. The external or internal control signal is processed in a control unit(210). The external or internal data contents are stored in a memory unit(220) by the control unit. An electronic picture frame is operated as a home network server or a home gateway through the internal communication unit.
