Available in PDF, EPUB and Kindle. Book excerpt: Digital Media: Voice, Video, Images, Quantities and Text The converged network carries all media: voice, video, text and images in packets. An essential first step is digitizing the media, representing it using 1s and 0s, to be carried in said packets. We’ll first understand analog vs. digital, how voice is digitized and reconstructed, the G.711 64 kb/s and AMR codec standards. The same principles apply to images and video in formats like jpg and mp4 video. We’ll make sure you are up to speed on binary and hexadecimal for quantities, and finish with ASCII and unicode for coding keystrokes and emojis.

Download or read book Media Studies 2 0 written by William Merrin and published by Routledge. This book was released on 2014-03-21 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Media Studies 2.0 offers an exploration of the digital revolution and its consequences for media and communication studies, arguing that the new era requires an upgraded discipline: a media studies 2.0. The book traces the history of mass-media and computing, exploring their merger at the end of the twenty-century and the material, ecological, cultural and personal elements of this digital transformation. It considers the history of media and communication studies, arguing that the academic discipline was a product of the analogue, broadcast-era, emerging in the early twentieth century as a response to the success of newspapers, radio and cinema and reflecting that era back in its organisation, themes and concepts. Digitalisation, however, takes us beyond this analogue era (media studies 1.0) into a new, post-broadcast era. Merrin argues that the digital-era demands an upgraded academic discipline: one reflecting the real media life of its students and teaching the key skills needed by the twenty-first century user. Media 2.0 demand a media studies 2.0 This original and critical overview of contemporary developments within media studies is ideal for general students of media and communication, as well as those specifically studying new and digital media.

Download or read book Deepfakes written by Graham Meikle and published by John Wiley & Sons. This book was released on 2022-09-22 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: What happens when we can no longer believe what we see? Show the AI technologies that create deepfakes enough images of a celebrity or a politician and they will generate a convincing video in which that person appears to say and do things they have never actually said or done. The result is a media environment in which anyone’s face and image can be remixed and manipulated. Graham Meikle explains how deepfakes (synthetic media) are made and used. From celebrity porn and political satire to movie mash-ups and disinformation campaigns, this book explores themes of trust and consent as face-swapping software becomes more common. Meikle argues that deepfake videos allow for a new perspective on the taken-for-granted nature of contemporary media, in which our capacity to remix and share content increasingly conflicts with our capacity to trust. The book analyses how such videos deepen the social media environment in which the public and the personal converge, and in which all human experience becomes data to be shared. Timely, clear, and accessibly written, this is an essential text for students and scholars of media, communication, cultural studies, and sociology as well as general readers.
