Abstract: An image processing method includes the following steps: performing first guided filtering on a target data to generate a first base layer data; generating a first detail layer data according to the target data and the first base layer data; performing second guided filtering on the first base layer data to generate a second base layer data; generating a second detail layer data according to the first base layer data and the second base layer data; converting the target data, the first base layer data or the second base layer data to obtain a converted base layer data; converting the first detail layer data and the second detail layer data to respectively generate a first converted detail layer data and a second converted detail layer data; and adding the converted base layer data and the first and second converted detail layer data to obtain an output data.

Abstract: Disclosed are a method and apparatus for encoding/decoding images. The image-decoding method comprises the steps of: receiving a bit stream including information regarding an NAL unit type; and checking whether or not the NAL unit in the bit stream is a reference picture based on said information regarding an NAL unit type and decoding the NAL unit. The information regarding an NAL unit type indicates whether the NAL unit is a reference reading picture or not a reference reading picture.

Abstract: According to the disclosure of the present document, a syntax structure and a syntax element may be provided wherein the syntax structure and syntax element enable, on the basis of whether an NAL unit type mixed with a picture is allowed, the existence of signaling-related information of a reference picture list with respect to a slice having a specific NAL unit type in the picture.

Abstract: A display system includes: a host processor which outputs first image data and outputs scan frequency information and a partial scan enable signal, based on an image driving frequency; a display module controlled by the host processor; and an interface. The display module includes: a display driving circuit which controls a selection of pixel rows to which the data signals are supplied based on the scan frequency information and the partial scan enable signal; and a display panel which displays an image on selected pixel rows based on the data signals. In a video mode of the interface, the host processor divides and outputs the first image data through the interface during transmission periods, based on the image driving frequency, and suspends an output of the first image data through the interface during suspend periods.

Abstract: A method for providing a main content and an extra content to a user by accessing said extra content through a reference item. The method includes receiving said main content from a first source and displaying said main content by said first device. Also, based on said reference item, said extra content is retrieved and/or received from a second source and simultaneously displayed together with said main content on said first device. Or said reference item may be forwarded to a second device, and thereby said extra content is retrieved and/or received from a second source by said second device and, simultaneously, the main content is displayed on said first device and the extra content is displayed on said second device.

Abstract: Method for providing a personalized content having a determined sequencing of media contents, comprising steps of: receiving, in a control channel, a control stream comprising temporal control information describing the content sequencing; receiving media streams comprising the media contents of the sequencing; and controlling a rendering of the personalized content by using said control information, wherein the sequencing comprising a first live program followed by a second live program, the method further comprises a step of detection of an overlap of the first and second live programs.

Abstract: An apparatus includes a storage unit to receive and store an image file, a processor to parse a media data field of the image file including one or more image data samples and to parse a media header field including an image type data field indicating whether each of the one or more image data samples is one of 2 dimensional (2D) image data and 3 dimensional (3D) stereoscopic image data to generate an image corresponding to one of a 2D image and a 3D stereoscopic image based on the image type data field of the image file, and a display unit to display the generated image according to the image type data field of the image file.
