Abstract: Provided is an apparatus and method for encoding/decoding a moving picture based on adaptive scanning. The moving picture apparatus and method can increase a compression rate based on adaptive scanning by performing intra prediction onto blocks of a predetermined size, and scanning coefficients acquired from Discrete Cosine Transform (DCT) of a residue signal and quantization differently according to the intra prediction mode. The moving picture encoding apparatus includes: a mode selector for selecting and outputting a prediction mode; a predictor for predicting pixel values of pixels to be encoded of an input video based on the prediction mode to thereby output a residue signal block; a transform/quantization unit for performing DCT onto the residue signal block and quantizing the transformed residue signal block; and an encoder for adaptively scanning and encoding the quantized residue signal block based on the prediction mode.

Abstract: Disclosed are an apparatus and a method for configuring an MMT payload header. The apparatus for configuring an MMT payload header, according to one embodiment, extracts a sequence number of a media processing unit (MPU) comprising one or a plurality of media fragment units, which are to be aggregated into one payload and mapped, and displays the extracted sequence number of the MPU on the MMT payload header. Specifically, the apparatus for configuring an MMT payload header displays the sequence number commonly associated with a plurality of MFUs on the header only once, when the plurality of MFUs in one payload are aggregated in the one payload and mapped.
