TL;DR: The basic concepts of video compression techniques are explained and several video compression algorithms have been developed to reduce the data quantity and provide acceptable quality.
Abstract: In today’s digital communication world, digital video communication can be found in many applications such as broadcast services over satellite and terrestrial channels, digital video storage, wire and wireless conversational services, etc. The quantity of data for handling the visual information is very large and needs very high memory for storage and large bandwidth of the transmission channel, so it is not practical to store and transmit the full digital video without processing. For instance, for handling a 720 x 480 pixel quantity of data per frame, having 30 frames/s, with a total of 90 min full color video, the data required is about 167.96 GB. Several video compression algorithms have been developed to reduce the data quantity and provide acceptable quality. This paper explains the basic concepts of video compression techniques.

TL;DR: In this article, the authors propose a video display method and a device which enables continuous viewing without forcing a viewer to perform setting operation of every content even when a content being viewed is switched.
Abstract: PROBLEM TO BE SOLVED: To provide a video display method and a video display device which enables continuous viewing without forcing a viewer to perform setting operation of every content even when a content being viewed is switched.SOLUTION: The video display method of this embodiment comprises steps of; detecting switching of setting from a 2D video viewing mode to a 3D video viewing mode; storing setting of 3D video viewing displayed on a display screen and selected; detecting whether a video content being viewed is switched; if the video content is switched, returning the selected setting of 3D video viewing to a previously stored initial value and if not switched, designating the 3D video viewing setting so as to continue the selected setting 3D video viewing; setting 3D video display according to the setting of the 3D video viewing which is set at the previous step; and displaying a 3D video according to the set 3D video display.

TL;DR: In this paper, a device for playing audios and videos includes a smart TV system-on-chip, a processor and a video format conversion bridge chip, which enables the device to both have high-definition frames and the function of being suitable for executing large-scale software so as to improve the user experience and willingness to use.
Abstract: Disclosed are a device and a method for playing audios and videos. The device for playing audios and videos includes a smart TV system-on-chip, a processor and a video format conversion bridge chip, wherein the smart TV system-on-chip is configured to receive audio and video signals and decode the audio and video signals; the processor receives the decoded audio and video signals and converts video signals in the decoded audio and video signals into first data format video signals; and the video format conversion bridge chip receives and converts the first data format video signals into second data format video signals, and provides the signals to a display screen to play, thus enabling the device for playing audios and videos to both have high-definition frames and the function of being suitable for executing large-scale software, so as to improve the user experience and willingness to use.

24 Nov 2006TL;DR: In this article, a video recording apparatus includes a data acquisition section, an encoding section, and a recording section, with a plurality of group of pictures corresponding to a cell in an optical disk format set as a recording unit.
Abstract: Disclosed herein is a video recording apparatus. The video recording apparatus includes a data acquisition section, an encoding section, and a recording section. With a plurality of group of pictures corresponding to a cell in an optical disk format set as a recording unit, the encoding section generates the streaming data by the time division multiplexing of the encoded data using fixed-data-length packets according to the optical disk format, and multiplexes, to the streaming data, specific information that includes information necessary for generating a navigation packet in the optical disk format and is difficult to obtain without analyzing the packets containing the encoded video and audio data such that the specific information is assigned to each group of picture using a private packet in the streaming data.
