The disclosure relates a display apparatus comprising: a signal input receiver receives a plurality of signals which are different in kind from each other, a plurality of encoders provided respectively corresponding to the plurality of signals, and perform encoding of a corresponding mode according to the kinds of at least one signal input to the signal input receiver among the plurality of signals, a first interface transmits a signal obtained by serializing the encoded signal, a second interface deserializes the signal received from the first interface, a plurality of decoders provided respectively corresponding to the plurality of encoders, and perform decoding and restoring the deserialized signal into the at least one signal, and a display displays an image based on the at least one restored signal.

Display device and control method thereof

An orthogonal frequency division multiplexing (OFDM) transmission device transmits OFDM symbols to at least one reception device and includes an OFDM transmission processing unit which generates a plurality of OFDM symbols; a pilot insertion unit which inserts pilot tones into each of the plurality of OFDM symbols; and a control unit which controls the pilot insertion unit to insert the pilot tones according to a pilot insertion pattern which is selected to correspond to a communication environment from among a plurality of pilot insertion patterns.

OFDM transmission/reception device for transmitting and receiving OFDM symbols having a variable data transmission rate and method thereof

A digital transmitting apparatus may include a first coder which codes a first layer data to add a first parity, a multiplexer which adds a second layer data to the first layer data to which the first parity is added, a second coder which codes the data outputted from the multiplexer to add a second parity, and a modulator which modulates the data to which the second parity is added and outputs the resultant data.

Digital transmitting and/or receiving apparatus and method thereof

An orthogonal frequency division multiplexing (OFDM) signal transmission apparatus and a method thereof are disclosed. The OFDM signal transmission apparatus includes an inverse Fourier transform (IFT) unit for transforming a frequency domain OFDM signal to a time domain OFDM signal according to one of transmission modes of 4K, 16K, and 32K; a guard interval inserting unit for inserting a guard interval into the transformed time domain OFDM signal according to a predetermined guard interval inserting rate; and a transmitting unit for transmitting the OFDM signal having the guard interval. Therefore, the data transmission rate is enhanced.

OFDM signal transmission apparatus and method

A beacon packet is provided. The packet includes a first information field that includes channel-time-allocation information in a wireless network; and information about whether there is residual channel time that can be allocated to a device that belongs to the wireless network.

Method and apparatus for wireless communication in high-frequency band

A method and apparatus for efficiently transmitting large multimedia data over a wireless network are provided. A wireless device includes a device information reading unit which receives and reads information regarding available capabilities of devices included in a wireless network; a control unit which selects a first device which can process a video stream and a second device which can process an audio stream from the devices based on the information; a stream generation unit which generates a video stream and an audio stream which form the same content; and a wireless transmission/reception unit which transmits the generated video stream to the first device and transmits the generated audio stream to the second device.

Method of transmitting/playing multimedia data over wireless network and wireless device using the method

A transmission packet structure for transmitting uncompressed AV data is provided. The transmission packet structure includes a payload including multiple TDUs error-correction coded at a predetermined coding rate, wherein the payload is classified according to importance of bits constituting the uncompressed AV data; a MAC header added to the payload, wherein information for medium access control is recorded in the MAC header; and a PHY header comprising information about the coding rate, wherein the PHY header is added to the MAC header.

Transmission packet structure for transmitting uncompressed A/V data and transceiver using the same

A decoding device having a turbo decoder and an RS decoder concatenated serially and a method of decoding performed by the same. A turbo decoder decodes received data of a channel and an RS decoder RS decodes the turbo decoded data. A controller controls the turbo decoder to iteratively turbo-decode the data according to a number of iterations determined by a stored iteration number and to cease the turbo decoding if an error correction completion signal is received from the RS decoder. The controller decreases the iteration number for a next frame of the data if the completion signal is received within the predetermined number of iterations and increases the iteration number for a next frame if the completion signal is not received within the predetermined number of iterations. The iteration number is changeable within maximum and minimum limits and may exceed the maximum limit in special cases.
