Digital Media End of Term 1 Unit 1 Paper 1

Digital Media

• High Definition Television is the best digital TV type at 720p, 1080i and 1080p formats. The number of pixels on the screen of the device equals the screen's resolution.
• ...is the process of obtaining and storing external data, particularly images or sounds , for use at a later time.
• ...digitized content that can be transmitted over the internet or computer networks. This can include text, audio, video, and graphics.
• A digitised platform for media delivery of video, audio and/or data to multiple networks, such as Telco, cable, satellite, digital terrestrial broadcasting and the Internet.

To what does the term 'Broadband' refer?

• technologies that let copyright owners control the level of access or use allowed for a copyrighted work, such as limiting the number of times a song can be copied
• This is the language which is used to create a web page or document on the World Wide Web. It instructs the browser on how to achieve font,images colour,graphics and hyperlinks etc.
• ...graphics that are formed through the use of mathematical equations which tells the technology how to create lines and curves in order to form a 2d image
• ...a telecommunication term referring to bandwidth data transmission. It is responsible for transporting multiple signals and traffic types of differing sizes.

Define 'Multicast'.

• ...a telecommunication term referring to bandwidth data transmission. It is responsible for transporting multiple signals and traffic types of differing sizes.
• ...the process in which one device transmits data/information to a specific/selected group of hosts on a network.
• ...text that has been embedded with instructions to take a web page viewer to additional information. It is not constrained to be text: it can include graphics, video and sound

Which of the following is an appropriate definition of New Media?

• ...highly interactive media that is easily processed, stored, transformed, retrieved, hyper-linked, easily searched for and accessed.
• For example, a file of size of 223 MB on a bandwidth of 56 kb/s would take approximately 9 minutes.
• This term refers to the notion that certain types of data should be freely available for everyone to use and share without restrictions such as copyrights, patents or other control mechanisms
• Reduction of a file size in order to conserve drive space, this also allows a reduction in network bandwidth requirement for sharing of a file.

What is Digital Convergence?

• A method of transmitting and receiving data over a computer network/server (Especially video and audio). It allows playback to start while the rest of the data is still being received.
• ...graphics that are formed through the use of mathematical equations which tells the technology how to create lines and curves in order to form a 2d image
• ...the system or set of rules by which data is sent from one device to another via the internet.
• ...the merging of mass communication outlets of such as; print, television, radio, the internet along with portable and interactive technologies various digital media platforms.It's the blend of multiple media forms into one platform.

• ...the creations of the mind, such as inventions, this enables the creator to gain recognition or financial benefits from what they invented.

• ...the minimum unit of a digital graphic that can be showcased on a display device. These are small tiny dots that make up images on devices' screen and it is short for Picture Element.

• ...the process of obtaining and storing external data, particularly images or sounds , for use at a later time.

• ...technologies that let copyright owners control the level of access or use allowed for a copyrighted work, such as limiting the number of times a song can be copied

Internet Protocol (IP)

• A digitised platform for media delivery of video, audio and/or data to multiple networks, such as Telco, cable, satellite, digital terrestrial broadcasting and the Internet.
• Frequencies or wavelengths being able to transmit data over a fixed amount of time. This is displayed on digital devices as bits or bytes per second and on analog devices it is showed as hertz. This can also be used as a measurement for broadband speed.

• The system or set of rules by which data is sent from one device to another via the internet.

JPEG

• JPEG refers to Joint Pixel Enhancing Group - a single image or a sequence of images that are recorded and played back, for example, a movie.

• The full meaning of JPEG is Joint Photographic Expert Group. This is the most common image file used by digital cameras as it can support compression and is ideal for web graphics.
• The format for broadcast of audio or video content over the Internet. It is not updated automatically.

• Jitter-Free Packet Enhanced Gateway - a telecommunication term referring to bandwidth data transmission.

Vector Graphics

• ...graphics that are formed through the use of mathematical equations which tells the technology how to create lines and curves in order to form a 2d image.

• ...the process in which one device transmits data/information to a specific/selected group of hosts on a network.
• one of several public copyright licenses that enable the free distribution of an otherwise copyrighted work.

What is the primary goal of the Open Movement?

• Promoting exclusive access to information

• Restricting collaboration and sharing

• Advocating for openness, collaboration, and shared resources
