Digital watermarking has become an accepted security technology to protect media such as images, audio, video, 3-D, or even text-based documents (Cox & Miller, 2002). Watermarking algorithms embed information into media data by imperceptible changes of the media. They enable copyright or integrity protection, broadcast monitoring, and various other applications. Depending on targeted application and media type, various concepts and approaches for digital watermarking exist.

This paper has proposal to develop audio-video synchronization in the bit-stream syntax using the Slice type and Macro-Block usage. The Media file like MP4, MOV and M4Vcontainer formats consists of both Audio and Video packed as tracks. The Video is encoded in H.264 format while Audio is encoded in AAC formats. There is a common way to achieve synchronization by looking into the type of Slice and the type of MB. This can be achieved by scanning across all the atoms present within the Media data. Time synchronization can be achieved by taking input from the Sample to Time atoms and feeding the data into Auxiliary units. The Slice type plays important role for synchronization as the decode order and display order for Video are different and sufficient time is taken to decode the video based on Profile, Level, type and number of Macroblocks for High profile. So the synchronization can be achieved for a Program stream or a Digital storage medium playback by synchronizing the formats based on type of slice information.

Embedding a hidden stream of bits in a file is called Digital watermarking. The file could be an image, audio, video or text. Nowadays, a digital watermarking has many applications such as broadcast monitoring, owner identification, proof of ownership, transaction tracking, content authentication, copy control, device control and file reconstruction. It is intended to complement cryptographic processes. It is a visible or preferably invisible, identification code that is permanently embedded in the data and remains present within the data after any decryption process. The focus of this paper will detail digital watermarking for multimedia applications and covered by definition of digital watermarking, purpose, techniques and types of watermarking attacks briefly discussed.

When designing a layout, the designer must be aware of fundamental principles so as to make the design structured and consistent. When planning layout, a designer cannot be random and must consider essential factors, such as the media type, the readers, the design elements and so on. Electronic media, like web pages and electronic books, is a newer media than the print media, and is different in several aspects. Yet, the basic principles of the design are still identical. A solid layout is a great tool in communicating messages visually.

Abstract This paper investigates what are the main components of consumer's inflation expectations. We combine the FGV's Consumer Survey with the indices of inflation (IPCA and government regulated prices), professional forecasts disclosed in the Focus report, and media data which we crawl from one of the biggest and most important Brazilian newspapers, Folha de São Paulo, to determine what factors are responsible for and improve consumer's forecast accuracy. We found gender, age and city of residence as major elements when analyzing micro-data. Aggregate data shows the past inflation as an important trigger in the formation of consumers' expectations and professional forecasts as negligible. Moreover, the media plays a significant role, accounting not only for the expectations' formation but for a better understanding of actual inflation as well.

ABSTRACTThis research is motivated by difficulties in fine motor skills, problems that occur in group A in Kindergarten IP Assalaam Tasikmalaya City, there are still many children who are less in fine motor development especially in motion skills of both hands, fingers and skill to coordinate the speed or dexterity of hands with eye movements. This is suspected because the learning in the classroom is still monotonous and the teacher still has not used the media, especially for the fine motor development. The purpose of this research is improve the fine motor skills of children through Balok Bergambar media in group A age 4-5 year in kindergarten IP Assalaam City Tasikmalaya. Classroom Action Research (PTK) conducted in collaboration with teachers, implemented 3 cycles using the Kemmis and MC Taggart Model. The subjects of the research were children of A kindergarten IP Assalaam Tasikmalaya City group consisting of 18 people, as many as eight male and 10 female and one teacher as a partner teacher. The object of research is the fine motor ability of the child through Balok Bergambar media. Data collection techniques used observation and documentation, while data analysis techniques using descriptive qualitative. Each cycle consisting of four and stages: planning, implementation stage, observation stage, and reflection stage. The results of the research have shown that the use of Balok Bergambar media can improve the fine motor ability of the child. This is evidenced by the increase in the ability of teachers in planning daily learning, the ability of teachers in the process of implementation of learning by using Balok Bergambar media and the ability to fine motor children aged 4-5 years from each cycle. Can be concluded the Balok Bergambar media can improve the fine motor ability of children aged 4-5 years in kindergarten IP Assalaam Tasikmalaya City. ABSTRAKPenelitian ini dilatarbelakangi adanya kesulitan dalam kemampuan motorik halus, permasalahan yang terjadi pada kelompok A di TK IP Assalaam Kota Tasikmalaya, masih banyak anak yang kurang dalam perkembangan motorik halusnya khususnya dalam keterampilan gerak kedua tangan, keterampilan jari jemari dan keterampilan mengkoordinasikan kecepatan atau kecekatan tangan dengan gerakan mata. Hal ini diduga disebabkan karena pembelajaran di kelas masih monoton dan guru masih belum menggunakan media, khususnya untuk perkembangan motorik halusnya. Tujuan penelitian ini adalah untuk meningkatkan kemampuan motorik halus anak melalui media balok bergambar pada kelompok A usia 4-5 tahun di TKIP Assalaam Kota Tasikmalaya. Penelitian Tindakan Kelas (PTK) yang dilakukan bekerjasama dengan guru, dilaksanakan sebanyak 3 siklus dengan menggunakan model Kemmis dan Mc. Taggart. Subjek penelitian adalah anak kelompok A TKIP Assalaam Kota Tasikmalaya yang terdiri dari 18 orang yaitu sebanyak  delapan orang laki-laki dan 10 orang perempuan dan  satu orang guru sebagai guru mitra.  Objek penelitian adalah kemampuan motorik halus anak melalui media balok bergambar. Teknik pengumpulan data menggunakan observasi dan dokmentasi, sedangkan teknik analisis data menggunakan deskriptif  kualitatif. Setiap siklus terdiri dari empat tahap yaitu perencanaan, tahap pelaksanaan, tahap observasi, dan tahap refleksi. Hasil penelitian yang telah dilaksanakan menunjukkan bahwa penggunaan media balok bergambar dapat meningkatkan kemampuan motorik halus anak. Hal ini dibuktikan dengan adanya peningkatan kemampuan guru dalam  merencanakan pembelajaran harian, kemampuan guru dalam proses pelaksanaan pembelajaran dengan menggunakan media balok bergambar dan kemampuan motork halus anak usia 4-5 tahun dari setiap siklusnya. Maka dapat disimpulkan media balok bergambar dapat meningkatkan kemampuan motorik halus anak usia 4-5 tahun di TKIP Assalaam Kota Tasikmalaya.

This article investigates the reality and variations of the European minority language media systems between 2009 and 2016, a period of serious economic crisis and accelerated digitalization process. To that aim, several parameters were measured: structure of the media systems and changes during that period along the variables of media type, ownership and reach; presence and relevance of major media in each of the communities; number and variation of full-time journalists; and the density or relative weight of the media systems with regard to the speaking population. The 10 minority languages under analysis (Basque, Catalan, Galician, Corsican, Breton, Frisian, Irish, Welsh, Scottish-Gaelic and Sámi) represent a wide range of communities. The relevance of the study lies in its direct comparative nature and in the fact that it thoroughly updates previous scholarly literature, measuring the changes which occurred within the 10 media systems.

The spread of digital media on the internet was very broad, fast, and cannot be monitored in a structured manner about what media has been uploaded and distributed on the internet network. The spread of digital media like this was very difficult to detect whether the media that shared was privately owned or that of others that is re-shared by media theft or digital media piracy. One step to overcome the theft of digital works is to give them a watermark, which is an identity that is placed on top of the work. However, this is still considered unsafe because the identity attached can be cut and manipulated again until it is not visible. In addition, the use of Steganography method to hide messages in an image can still be manipulated by adding messages continuously so that it accumulates and damages the original owner of the image. In this article, the author provides a solution called Digital Watermarking, a step of encrypting the data of the original owner of the work and putting it into the image of his work. This watermark cannot be seen clearly, but actually in the media there is encrypted data with a strong Advanced Encryption Standard (AES) method. As a result, a tool that can improve the security of media owner data by combining the AES and Steganogaphy methods in the formation of new media that cannot be changed anymore. So, when the media is stolen and used by others and has been edited, the owner's personal data can never be changed.

The tremendous advancement of digital technology has increased the ease with which digital multimedia signals (image, video, audio) are stored, transmitted, and reproduced. Consequently, the content providers and owners are faced with problems of protection against copyright violation and other forms of abuse to their digital property. Digital watermarking has been proposed in the last decade as a solution to prevent illegal and malicious copying and distribution of digital media by embedding an unnoticeable information into the media content. This chapter describes three imperceptible and robust watermarking algorithms for different types of multimedia objects (image, video, audio). The three algorithms are based on cascading two powerful mathematical transforms; the Discrete Wavelet Transform (DWT), and the Singular Value Decomposition (SVD). The two transforms are different, and thus provide complementary levels of robustness against the same attack. In the proposed dual-transform algorithms, the watermark bits are not embedded directly on the wavelet coefficients, but rather on the elements of singular values of the DWT sub-bands of the multimedia object. Effectiveness of the proposed algorithms is demonstrated through extensive experimentation.
