Types of Digital Media Technology- An Overview of the Field

July 28, 2019 posted by



hello welcome students to the NPTEL course visual communication design for digital media and in this module we'll start discussing about types of digital media technologies and this before we have started design discussing on V what is visual communication design so we discussed what are the elements of visual communication design what are the principles of visual communication design and from this module onwards we'll start discussing on what is digital media digital media is also sometimes called new media because new media is that paradigm where the digital influence the digital platform is started so to understand digital or new media we need to understand what is media what we talked about what we denote when we tell this is digital or traditional media so media is a platform or mode of mass communication so the platform where people interact where people interact with each other by sharing knowledge by sharing news sharing information or people take or gather knowledge from a from a particular interface it can be a digital interface it can be a traditional interface so for example if we think about the previous times when people used to start we're used to spread news by by announcing announcing in a public plaza and playing drums and then they started announcing or within announcing different news and that was the initial started starting of communication then there are scroll paintings then there were paintings on charges wall painting on even the cave paintings are also a way of communication and gradually we evolved from that era and the the newspapers pamphlets all this print media started and right we are in the age of computer and the computer became the platform of media and from that time onwards we started talking about digital media as a new media and that's the paradigm shift so initially the paradigm of media was completely different it was traditional right now it is based on digital so if we think about the evolution first the traditional media's were theater performance paintings even in Indian context we have our school paintings we have our wall paintings like Madhubala we have Schoen paintings like Potter Chitra's those were the traditional media's and even the shadow puppetry is those were the traditional Indian in Indian context those were the traditional media or additional old media then when during the reign assign Europe Gutenberg developed a machine which is press and the first he what he printed was the Bible the Gutenberg Bible that was around 1440 s so that time onwards print media started and the print media with in print media we have newspaper we have we have pamphlets we have advertisement posters so actually from if we compare the theatre performance theatre performance has capacity to target less audience only a theater hall only who's even there were paintings on the charges hall who's visiting this charge can only see that can have the communication can have a interface between the painting and humans communication cannot happen but in print media has larger reach it can target larger audience so this was actually required during the Renaissance aware people migrated from village to cities and industrial revolution started so during Industrial Revolution advertisement of new products were required and that time rail engines and all these things were started developing so newspapers were easy to destroy it distributes to vehicles like our rails and it reaches a larger target audience so the capacity to target an audience is gradually becoming higher even from print media – if we think about the invention of first programmable computer that is that happened on 1830s by Charles Babbage so computer has even larger it can target even larger target audience so it can actually have an impact globally so it doesn't need to reach the user into in forms of tangible newspapers where the informations can be digitally stored and anybody from all over the world can access the media so gradually the media become more popularized it can one information can be accessed by many people so in today's the digital or new media we have social networking sites like Facebook like our code which initially was there and other social networking sites like whatsapp mobile application where people communicate and even the people whose especially distant like sitting in a different country they can communicate through these social networking site and in exchange information and knowledge even the animated movies which can which we can upload in digital platforms like YouTube and all over the world people can see that and even the digital games somebody from other side of the earth is programming the game and we are playing it so these are their new digital media platforms which are available today so what are the characteristics of new media so it's based on digital platform definitely and all digital media including text image video it can be 2d on 3d shapes all are 2d and 3d shapes for example buttons and way it comes beta comes on the button which we use for navigation which we will discuss in the later classes and so all these are actually digital informations which we can store which we can use in digital media platform and the main thing is it can allow easy access and larger target audience which we discussed earlier that the target audience and accessibility and is gradually increasing in media from traditional old media to the new paradigm of digital media so in contrast at old media new media is interactive and yes if we consider the painting on the wall of charges or the scale paintings users cannot interact with that the way the performers are performing the theatre the way a painter is painted user can only have that information but here if you are think about animation if we to think about a gamified experience of our web application we can click on a particular button and see what information we need so here actually users involvement is much more and user can tweak user can select what elements they want to display and they can create their own path of interactiveness so there is a huge stick experience which they can regenerate and each and every users heuristic experience will be based on their its it will be a subjective and based on the particular user so he mystic experiences like the term heuristic is means that the way a user interacts with the interface or the way they evolve the interaction evolves to around the user so it's a term which will be again discussed in the detail of the detail discussed in detail in design methodology so here on the this side we have traditional old media I have selected Indian traditional media for example this first is covered or fainting covers would enshrine is based on Rajasthan so they used to tell a story by these four LED panels of wooden panels so we actually one wooden panel will unfold and one story will they will there will be a narrative there will be a song attached to each and every painting and then again they will unfold another panel and the another song will start so gradually this is actually a storytelling approach while traditional Indian their understanding of vernacular artists used to follow this one is actually a Bengal Potter Chitra this is been called petitioners diagram Khurana so this is also as a school printing of bangles so similarly they also have each and every butter has one song associated to this so this is actually a vertical school where there are multiple frames so actually I this each and every frame you can connect this with animated movies so each and every frame has one shot and one song is there and the next shot begins and the next painting must they unfold to the next painting and the next song starts so this is a traditional media media which evolved into animation and movie from there so this is also this is a column carry your painting for South Andhra Pradesh so here are the paintings are there and also Telugu and scripts are also there which describes the painting this is a covert venting from Bihar this is a wall painting where there is a graphics there is a storytelling approach is applied here through the where the base is wall here in the new media we have on other side web applications digital graphics animated films and digital gaming interfaces so if we start discussing new media we need to understand the salient features and characteristics of new media so new media as described by lev manovich in his book the language of new media as by MIT press you can follow this book this book in this book commander which describes the five key characteristics of new media the first he says its it has the potentiality of numerical representation second it has it has a modularity it has more term to represent new media a modular approach is followed if there is a power provision of automation and variability based because of the numerical representation and modularity of representation modularity of deep data representation and it follows a principle of transcoding so we'll discuss this five principles in detail so first is numerical representation all the new media objects can be described is represented mathematically which computer stores the information stored in the computer is a mathematical information which transforms into a display system and we understand that there we don't see the mathematical code behind the new media design we see a visible display it can be in terms of text it can be in terms of videography sound it can be in terms of steel pictures so because of this numerical representation manipulation using algorithm is possible which was not possible in the form of an jebel old traditional media so new week a design for example other the manipulation using is like noise reduction or reduction we can reduce the noise digitally after creating first numeric the model copy of the digital media then we can also increase for example we can increase or decrease color contrast after creating the visual so these are possible because the information stored is in terms a terms of mathematical numbers the another thing is the information stored has a same pattern the same basic modular is repeated to store an informations and the same module can be scaled up can be scaled down within a module the same module can be repeated so it's it has a actually it has a fractal structure so the fractal structure is represented in infographic le here so all the informations in digital media's are has the same modular unit so the modular unit can be repossessed to represent a 2d image it can be invoked cell to represent a 3ds image a 3d 3d digital image like when we are designing an animation 3d animation we are creating a character of a 3d animation all informations of a 3d and 2d informations are represented in terms of voxels and similarly our characters and scripts help to represent the typography image and all the informations in digital media so the next characteristics is automation automation is actually possible because of numeric and modular representation of new the possibility of modular representation and you make coding of a new media so as an example if we have a template which is already automated template and we can create a website based on the same template multiple ways that can be created from based on a particular single template even the Photoshop filters also they are all programmed filters in Photoshop and other digital graphics tool like illustrator and others so there are filters which the proper proper algorithm is written for this filter and we can have different image to go through this that filter and transform into a particular visual style stylistic visual so for example in the first we have a digit we have a photograph a real photograph of prints of card in Kolkata and on the right hand side we have Katsushika Hokusai is a great wave so grateful is so famous pea which would cut painting so this is actually a filter which new mobile based application is generated a filter which has the visual quality of this painting Katsushika Hokusai is a great wave so visual qualities are deciphered in terms of elements of design so same blue colors the color tones of blue the line qualities and the textures are taken from this original painting and if we see the color of this is actually different the color of this is also a different tone but when I have applied the filter which is derived from Katsushika Hokusai is a great wave to the original pic photograph the this color is changed into the original the inspiration of where the filter is inspired from this great waves color so the elements of design is changed and then the the line qualities which were where we see in the wave are also repeated over here in this to depict the cloud so the line qualities are also varied from this great way the painting of Boucher and translated into the image so by this way actually are the elements of designs are transformed and March with our image by the by the principle of automation this is only possible because of new media applications and the new media applications all these images are actually stored in mathematical numbers and module in a modular format that's why the and a previously coded algorithm which is taken from this this image can be applied on the other image so this is possible in new media which was not possible in the old on traditional media digitally so the another quality of another characteristics of new media is variability so where it can the new media objects are not fixed forever so it can be manipulated in variable format so there is because this is also happening because of the modularity and numerical coding which we do which are the first to grab placed is we are discussed so for example from the model or copy we can change we can make many other different copies we can change the format of the copies for example when a movie releases the movie can also be seen in mobile which can also be transformed into a feature into the screen of a particular aspect ratio for example the flight in the flight there are this a movie or display our systems where the movie is digitally modified to fit into there that display system which we see in the flights so for example we have we had this project humphy which is created by unesco for conservation of humpy of india so which is a UNESCO World Heritage Site so digitally so digitally what units could be digitally documented digitally photographed Humvee and created a 360-degree panoramic view of humpy so humpy this project then this project is actually digitally stored and they can display this in any form in a 360-degree panoramic view in any part of the world so this after documenting there can be multiple copies so people don't need to go to the humpy and see the monuments of traditional Indian monuments so they can be this hampi web project is also displayed in australia so our people can go to Australia and Australian people can also see this project by just going there and digitally experiencing what was what is there in the indian hated site humpy so again as simultaneously this project can be shown in many our places of the places of the world and in many format we can see this thing in TV television we can see this in laptop we can see this in mobile also we can see this in this kind of 360-degree panoramic screen so the another characteristic Sanibel possibility with new media platform is transcoding it is an interface between human and computer the computer understands a different language but human perceives a different language but new media can cater to because because of the digital platform it can cater a new media can cater to the computer it can it can take the benefits of computer programming and also it can display things to human being and so there's another term we have to discuss here is hyper media it's an extension of hyper texting and where the nonlinear heuristic here interaction happens between user and computer so if we have hypertext so people can select a particular hypertext and they can select the particular path which we are discussing in the beginning of the lecture so a process of coevolution co-creation and Co design is there and which unfolded because of the new media paradigm so for example website a mobile application game which we have which we can we can interact as the way we want and there are also some multimedia where which cannot be that interactive for example animation movie and digital graphics but still we can pause the we can switch we can pause the movie again we were rewind and see it again which was not possible in the traditional media like scroll players as well printing and if we were seeing a performance in theater so these are the characteristics of a new media and we'll again discussed in detail in the next lecture how the visual communication design can affect in can be applied in new media paradigm thank you
