This study suggests that the application of split screen as visual media can attain the effect of diversity through providing rich information and accepting diverse contents as gorgeous aesthetics. Single images are analyzed as appropriate to a demanded concentration genre such as news and dramas, entertainment. In contrast, images with natural images and ads images those are more appropriate and analyzed as the genre of the split-screen which is highly efficiency to the contents and also highly efficiency to the spatial diversification. In introducing various genres of digital contents into split screen, the synergy of contents is induced by placement in consideration of the characteristics of split screen position. In order to increase the concentration of the split-screen image, using the left area and right area above it, can increase the effectiveness of the content.

In this paper, I examine the history of split screens, primarily seek to explain types of them, and explore the narrative meaning of each type in feature films. In short, I try to categorize the types of split screens and present a figure of them according to events and characters, focusing the relations between/among simultaneous images and narrative meanings. In addition, I assert that split screen have altered some methods of filmic storytelling and the ontology of screen. Story lines no longer have to be linear and the screen need not to remain a window through which we can see another world. The screen has come to be a canvas upon which several images can be arranged for narrative purposes.

The split-screen function on the multipoint control unit(MCU) which is usually using processing method based on pixel domain has many problems for manipulating the video signal in real-time. Although the researches and the developements to cope ith such problems are processing, these have too complex architecture to implement and are limited to method for H.261 video signal. In this paper, we propose a new mechanism for split-screen that can actually apply to ISO/IEC MPEG video standard. The new method that is proposed in this paper do the processes in complete compression domain, thus it is suitable for the application of real-time multipoint multimedia communication service. By simple interpreting and manipulating the MPEG video element stream, the split-screen functional module can be implemented easily and the result of the procedures does not accompany image degradation at all. Finally, the complexity of implementation, the aspect for processing delay and the loss of image quality as compared to that resulting in the case of applying the previous split-screen method has been investigated. And it is confirmed that the proposed mechanism has a significant advantage as a split-screen method.

The phase-screen and the split-step Fourier migrations, which are implemented in both the frequency-wavenumber and frequency-space domains by using one-way scalar wave equation, allow imaging in laterally heterogeneous media with less computing time and efficiency. The generalized-screen migration employs the series expansion of the exponential, unlike the phase-screen and the split-step Fourier migrations which assume the vertical propagation in frequency-wavenumber domain. In addition, since the generalized-screen migration generalizes the series expansion of the vertical slowness, it can utilize higher-order terms of that series expansion. As a result, the generalized-screen migration has higher accuracy in computing the propagation with wide angles than the phase-screen and split-step Fourier migrations for media with large and rapid lateral velocity variations. In this study, we developed a 2D prestack generalized-screen migration module for imaging a complex subsurface efficiently, which includes various dips and large lateral variations. We compared the generalized-screen propagator with the phase-screen propagator for a constant perturbation model and the SEG/EAGE salt dome model. The generalized-screen propagator was more accurate than the phase-screen propagator in computing the propagation with wide angles. Furthermore, the more the higher-order terms were added for the generalized-screen propagator, the more the accuracy was increased. Finally, we compared the results of the generalizedscreen migration with those of the phase-screen migration for a model which included various dips and large lateral velocity variations and the synthetic data of the SEG/EAGE salt dome model. In the generalized-screen migration section, reflectors were positioned more accurately than in the phase-screen migration section.

We present the design and implementation of a novel anti-malware system called SplitScreen. SplitScreen performs an additional screening step prior to the signature matching phase found in existing approaches. The screening step filters out most non-infected files (90%) and also identifiesmalware signatures that are not of interest (99%). The screening step significantly improves end-to-end performance because safe files are quickly identified and are not processed further, and malware files can subsequently be scanned using only the signatures that are necessary. Our approach naturally leads to a network-based anti-malware solution in which clients only receive signatures they needed, not every malware signature ever created as with current approaches. We have implemented SplitScreen as an extension to ClamAV, the most popular open source anti-malware software. For the current number of signatures, our implementation is $2{\times}$ faster and requires $2{\times}$ less memory than the original ClamAV. These gaps widen as the number of signatures grows.

Recently, it isn't hard to find split screen effects in films, TV dramas and commercial films which composes a screen with different frames of images. The TV series '24' which was produced in USA in the year 2001 and is expecting the release of its 7th series next year frequently exhibits such split screen methods. '24' is a TV drama of the events taking place in one day which is produced in the form of real-time mode and consists of 24 episodes which is an hour long. Using split screen method, the drama effectively delivers the events simultaneously taking place at different locations. Moreover, the divided frames of each screen relates to one another by means of collision, synthesis and ect. which captures the vision of the spectators. This study aims at analysing the relationships between the frames which consists split screen scenes in the drama '24' and discover its eye capturing attractions using film montage theories.

Computer technology pursuing more innovative image than before, makes some characteristics which distinguishes the digital fiction film from the analogue fiction film. One hand, the split screen in analogue film aides the development of drama in the aspect of narrative, on the other hand, it controls the psychology of spectator. The composite image in digital fiction film by computer graphic, and elaborated digital editing show many innovation in the field of audiovisual. In this context, I would like to remark on the digital film (2003) directed by Ang-Lee. In , the split screen and the composition of the fast transiition of shots in the scene of laboratory were created by computer graphic program for special effects. As visual special effect plays an important role in digital film, its narrative space creates a space which is distinguishable from that of analogue film.This can be an example which says a lot for the special aspect of digital narrative.

This paper examines how split-screen technique works to meet the goals and strategies of the narrative in the romantic comedy films which deal with love and sex. The plot of romantic comedy films aims to the union and marriage of the couple, but is structured to delay the union as much as possible through comical situations and episodes. Usually split-screen scenes are placed before plot point 2 and serve to make a laugh and humor. Besides, it helps focusing on two main characters. Comedy related to love and sex comes from information gap between two main characters which can cause a tension, double meaning of spoken words and combination of split-screen images. Michael Gordon's Pillow Talk(1959) and Peyton Reed's Down with Love(2003) are reviewed in this study.

Screen splitting is one of the fundamental tasks in different methods including video and image compression, screen classification, screen content coding and the like. These methods in turn support various applications in data communications, remote screen sharing, remote desktop delivery to assist teaching-learning, telemedicine, Desktop as a Service etc. In the literature we find systems requiring splitting assumes a fixed size split that do not change dynamically, also there is no analysis why that split is chosen in terms of performance. By doing mathematical analysis this paper first finds the efficient splitting schemes that can be easily automated to make a system adaptive. Thereafter, taking the screen motion detection as a case study, it demonstrates the effects of various splitting methods on motion detection performance. The simulation results clearly shows how classification performances varies with different splitting which will facilitate to choose the best splitting for a specific application scenario as well as making the system adaptive by providing dynamic splitting.

In this paper, we propose a session management and control architecture for N-Screen services, which enable users to change devices and transfer contents among user's devices during service by session transfer and split. In N-Screen services, users may have multiple devices with different attribute such as screen resolution, CPU capability and access network interfaces. Also, since users may change devices during service, or one user may use multiple stream, N-Screen services need to enable the user to share and transfer contents across N-Screen devices. We introduce the management and control servers to provide session split over user multiple devices and session continuity while changing device. Furthermore, the proposed architecture provides the device capabilities aware session continuity. In addition, the proposed scheme minimizes the session transfer delay and content server processing load. We present results that show the effectiveness and usefulness of proposed architecture.
