Abstract: An apparatus for decoding video data includes a decoder configured to decode, from a bitstream, a syntax element indicating an intra-prediction type of a current block of the video data, and an intra-predictor configured to generate a prediction block for the current block by selectively performing matrix based intra-prediction (MIP) or regular intra-prediction based on the intra-prediction type of the current block indicated by the syntax element.

Abstract: Image decoding of decoding a sequence of coded pictures on a block-by-block basis is provided. The image decoding incudes decoding a first high-level syntax element from a bitstream to determine, at a sequence level, whether affine motion prediction is allowed. A second high-level syntax element is extracted for each of at least one coding tool from the bitstream depending on the first high-level syntax element. At a picture level, the method determines whether each of the at least one coding tool is allowed. The coding tool includes sample-by-sample adjustment of affine motion prediction samples.

Abstract: A method and device for controlling coding tools are provided. The video decoding method includes decoding, from a high level of a bitstream, an enable flag indicating whether one or more coding tools are enabled. The coding tools includes a first coding tool that encodes sample values using luma component mapping based on a piecewise linear model. The method includes acquiring a value of an application flag depending on a value of the enable flag, by setting the application flag indicating whether to apply the coding tools to a predetermined value, or by decoding the application flag from a low level of the bitstream, the application flag including a first application flag indicating whether to apply the first coding tool. The coding tools are operated when the value of the application flag is a value indicating that the coding tools are applied.

Abstract: A reliable data transmission method and system based on a predicted amount of data in a vehicle-to-infrastructure (V2I) network is disclosed. A data transmission method of a base station includes determining a maximum amount of data to be transmitted from the base station disposed around a road to a vehicle traveling on the road, determining an encoding number for systematic network coding (SNC) based on the determined amount of data, performing the SNC on original data based on the encoding number and the amount of data, and transmitting encoded data obtained by performing the SNC to the vehicle.

Abstract: A test apparatus for generating a test case based on a fault injection technique and a method of controlling the same are disclosed. The method includes identifying at least one function in a program to be tested based on a software detailed design, generating a test design document based on fault location that can be generated in connection with the identified at least one function and a fault type to be injected into the fault location, searching for the fault location to be injected based on the generated test design document and source code of the program, determining a fault injection scheme and the fault type, and predicting a result by applying a fault injection corresponding to the fault injection scheme and the fault type into the searched location to generate a test case.
