Raster and Vector

Raster

A raster Image is made from individual dots in an array (matrix) and contains display information specific each unto itself. A raster is a large collection of paint spots all coming together to make an image and each spot/dot has information about the image like what colour it has and its saturation and so on. Remove the spot the image remains intact, minus a spot.

 

Vector

A vector is made up of one or more lines and the fills are defined by mathematical equations. If created a shape the computer calculates a mathematical equation to decide how large the shape will be. Once calculated, the image is displayed as an array of dots on the monitor.

 

Media Studies

Today in media studies we have studied how the media world effects people in different ways. like for example music have different genre’s and each genre has a group of different age groups and all the different types of media has genres and within the genres have different groups for everyone. the different types of media are film, TV, publishing, music, games and radio. the media are targeting everyone and every age group because if their is a chance to make money then they will do it and everyone learns and adapts from the media for example people learn about different country’s and different things through the media and some people believe what they are told through the media which some are true and some are not. the media world is used by everyone and never stops getting used because people learn and adapt from it but not everyone uses all the types of media some will watch a film but some will read the book and some will do both. radio stations make money by advertising adverts and the music is to get an audience the present the advert to.

the media have a method of class’s for the targeting audience and they are classed in letters and numbers

The NRS social grades are a system of demographic classification used in the United Kingdom. They were originally developed by the National Readership Survey in order to classify readers but are now used by other organisations for wider applications and market research.

The grades

Grade Social class Typical occupation
A upper middle class doctor, solicitor, barrister, accountant, company director
B middle class teacher, nurse, police officer, probation officer, librarian, middle manager
C1 lower middle class junior manager, student, clerical/office workers, supervisors
C2 skilled working class foreman, agricultural worker, plumber, bricklayer
D working class manual workers, shop worker, fisherman, apprentices
E underclass casual labourers, state pensioners

The grades are often grouped into ABC1 and C2DE and these are taken to equate to middle class and working class respectively.

Demographics refers to selected population characteristics as used in government, marketing or opinion research, or the demographic profiles used in such research. (Note the distinction from demography, see below.) Commonly-used demographics include race, age, income, disabilities, mobility (in terms of travel time to work or number of vehicles available), educational attainment, home ownership, employment status, and even location. Distributions of values within a demographic variable, and across households, are both of interest, as well as trends over time. Demographics are frequently used in economic and marketing research.

Demographic trends describe the changes in demographics in a population over time. For example, the average age of a population may increase.

today in media studies we are looking at the different media industries like music, games, cinema, TV, radio and press. also we looked at the different local media industries which is called Geodemographics. we talked about how the different media industries don’t know how their targeted audiences want and how they have to find out. we also talked about how the PSB (public service broadcasting)don’t make money of the advertises and that they make money though the TV licence the public pays. we also talked about how the music industries don’t know what singles are going to sell the most so they release alot of different ones and finds out which one does the best and this is a bit different to the cinema because the film that is made costs a huge amount of money that they make alot less then the music industry. the TV channel provides the viewers with a different range of things to watch that they will be something for everyone. we talked that different newspapers will be sold in different areas for example the TIMES will be sold around a area which is more posh and the DAILY STAR will be sold around a area with less posh abit and the same goes with the music for example posh people is more likey to listen to classic music where as a lad from the estate will be listening to something like rap and mc stuff. 

 Ofcom is the independent regulator and competition authority for the UK communications industries, with responsibilities across television, radio, telecommunications and wireless communications services.

OFCOM is a authority that you can complain to about anything that you seen on TV or heard of. OFCOM stands for office of communication.

Music

Can’t predict the market
Portfolio management (a lot of products of different types)

-

Games

Cover the genre’s or types of games
To address a demographic

-

Cinema

Features in common with music industry + games
Cover the genres

-

TV

Make a variety of programmes in genre types
The less successful ones drop quickly

-

Radio

Make a variety of programmes in genre types
Commercial radio targeted at very specific audience

-

Press

Small number of national papers (8) each appeals to a demographic
Magazines  Fine tuned to specific demographic  Attractive to advertises

 Genre

genre is a french word for ‘type’ and it means a style or type of product for example a film will have a horror style and the audience will expect to see a lot of blood and scary stuff in horror films and Genres are formed by sets of conventions.

the audience will have certain expectations for the genre because genres are what defines the products and that’s why the audience will have expectations for example if someone went to see a hard metal band play and when they got there they start playing classic soft music the audience will be disappointed because it is not what they played for.

 different genres

 music, games, Internet, TV, books and magazines

music

classic, R’n'B, rap, pop, rock, punk, country and metal 

games

action, adventure, quiz, sports and gambling

Internet

blogs, porn, gambling, games, news, shopping and file sharing

TV

soaps, shows, music, cartoon, films and documentary

books

horror, crime, true story, facts, comics and documentary

magazines

gossip, sports, facts and fashion

 codes and conventions

i am going to explain what codes do in the media and then i will explain what conventions do after that i will explain what they both mean.

codes

codes are systems of signs in the media which create meanings and codes can be divided into two categories which are technical and symbolic. the technical codes are all the ways in which equipment is used to tell the story in a media text, for example the camera work in a film. the symbolic codes show what is beneath the surface of what we see. for example, when a character cries we know that the character is sad so characters actions show us how the character is feeling. some of the codes fit both categories for example, music fits into both by technical and symbolic.

conventions

Conventions are the generally accepted ways of doing something. There are general conventions in any medium, such as the use of interviewee quotes in a print article, but conventions are also genre specific.

how codes and conventions both fit into the media is that Codes and conventions are used together in any study of genre – it is not enough to discuss a technical code used such as camera work, without saying how it is conventionally used in a genre. 

File Format Research

BMP, TIFF, GIF, JPEG 

BMP

A BMP file format stands for bitmap picture and it was created by Microsoft for the windows program. It is the most common still image on the PC and the BMP images can range from black and white (1 bit per pixel) up to 24 bit colour (with windows XP it can range up to 32 bit colour) 16.7 million different colours. Although it was made for a windows computer it is supported by many non-windows computers. 

JPEG

JPEG stands for joint photographic expert group and it is commonly used to minimize graphic file size on the web and the images are full-color (24-bit, “true color”) images. The JPEG has a huge compression ratio which means the downloading speed will be much faster.

TIFF

TIFF stands for tagged image file format and the TIFF allows you to have a flexible set of information fields and the TIFF also allows you to a more wide range compression schemes and color spaces. TIFF is one of the most powerful when it comes to support for a wide range of data types, you can store signed or unsigned integers, floating point values and even complex data in there too. A TIFF denies support for multiple images in a single file.

GIF

GIF stands for graphic interchange format and the GIF uses a relatively basic form of file compression (Lempel Zev Welch, or LZW) that squeezes out inefficiencies in the data storage without losing data or distorting the image. The LZW’s job is to improve the efficiency and therefore reduce the GIF graphics size. The strategy is to reduce the number of colours of the GIF image to the lowest number you can and to remove the stray colours that will not be required in the image and the GIF graphic cannot have more than 256 colours but it can have fewer colours down to the minimum, of which two are black and white.
