The equalizer equalizes the demodulated DTV signal using the detected known data, and the transmission parameter detector detects an error correction mode from the equalized DTV signal. Finally, the block decoder decodes the equalized DTV signal for error correction using the detected error correction mode.

Abstract: The present invention relates to a A moving image coding apparatus and method involving the simultaneous parallel running of respective modules, namely: a segment-unit-coding module in which an input image frame is divided into segment units and the integer pel (integer pixel) motion is estimated while at the same time the 1/n pixel images are generated with respect to the segments of the image coded in the coding module; and a macroblock-unit-coding module in which the segments of the image frame whose the integer pel motion has been estimated in the segment-unit-coding module are received as input in the form of macroblock units and are coded in macroblock units through the 1/n pixel motion estimation. By separating the coding units into different modules and employing the techniques of parallel processing and pipelining, the present invention makes it possible to effect high-speed encoding with reduced delay in the coding rate due to differences in the processing speeds of the respective modules.

These transmit-side innovations include circuit configuration and signal processing methods for mapping Ku “input subcarriers” to N “output subcarriers,” where the “output subcarriers” are some or all of the subcarriers defined for the SC-DCT OFDM signal. In one or more embodiments, Ku is less than N, and the mapping is based on advantageous DCT/IDCT precoding. The present invention additionally or alternatively includes advantageous frequency-selective mapping, and further provides a corresponding receiver apparatus and associated method, for receiving and de-mapping the SC-DCT OFDM signals contemplated herein.

Abstract: The present disclosure discloses a digital-to-analog converter (DAC) design which is suitable for providing a high output power high-speed DAC, e.g., in radio frequency applications. The DAC design utilizes a parallel DAC structure, e.g., having 8 parallel DACs and an aggregate current output, to provide a high and programmable current output (in some implementations, up to 512 mA or more). The parallel DAC structure alleviates the design problems which exist in trying to output a high amount of current using a single DAC. The DAC design further utilizes a hybrid structure which integrates the signal chain for a more reliable system. In some embodiments, the hybrid structure uses a CMOS process for the current sources and switches and a GaAs cascode stage for combining the outputs to optimally leverage the advantages of both technologies. The result is a highly efficient DAC (with peak output power programmable up to 29 dBm or more).

Each of the coding units (102), (103) and (104) determines a prediction method for the component picture at the time of coding.

Abstract: An apparatus generates an image signal in which pixels are encoded in N-bit words which encode at least a luma per pixel. A receiver (201) obtains high dynamic range pixel values in accordance with a first color representation in M-bitwords. A first generator (203) includes the high dynamic range pixel values in the image signal in the N-bit words according to a second color representation. A second generator (205) includes in the image signal an indicator that high dynamic range pixel values are encoded. In some examples, the high dynamic range pixel values may be provided in a segment that can alternatively contain high or low dynamic range pixel values, and the indicator may indicate which type of data is included. The approach may e.g. facilitate introduction of high dynamic range capability into e.g. HDMI systems.
