Technology

Digital video capture

• Digital video capture is the process of converting an analogue video produced by a video camera or DVD player to digital video.

• Example - MoviePlus makes it easy to capture your own video and audio footage to your PC from tape based digital camcorders , analogue video sources. (e.g. analogue camcorders or TV all via a capture card) or USB web cams.

• Platform – World wide web, presentations, device, card, software.

Compression

• (Lossy) compression is a data method that compresses data by losing some of it. This aims to minimize the amount of data that needs to be held, handled, and/or transmitted by a computer.

• (Losless) data compression is data compression that allows the original data to be perfectly reconstructed from the compressed data.

• Example - These are used in email attachments as files may be too big to attach in an email so need compressed.

• Platforms – DVD, CD, Mobile devices

Lossy advantages

• Lossy compression can be used for nearly any type of multimedia file, such as audio and video files as well as images. Lossy compression can be used for a number of reasons, such as transferring files over the internet or for storage purposes, but is especially used for streaming multimedia files.

Lossy disadvantages

• In lossy compression, the data is lost through compression on purpose. Every time the file is re-edited/saved further data is lost. Finally, lost data stops the file from archiving.

Lossless advantages

• In the lossless compression, data is kept from being lost in order to maintain the original content.

• It's lossless so you don't lose any information and the output is an exact copy of the input.

Lossless disadvantages

• Lossless compression uses more memory than lossy compression.

• Sending uncompressed lossless files over the internet is expensive. Even with fast broadband there is still a limited amount of bandwidth available. So even though storage is cheap the cost of sending the files is very high.

Lossy affect

• The affect lossy files would have on the final video quality and the applications it is used for would be poor quality of audio and the visual video.

Lossless affect

• The affect lossless files would have on the final video quality and the applications it is used for would be good quality as it is the original way and file that was recorded, nothing has been compressed or lost so the audio and visual video footage is clear.

Digital video file formats

• Digital video file formats are when videos have been made and are then saved onto a computer and are saved as a certain file formats.

• Platforms – DVD, CD, Email attachment, world wide web, mobile device, presentation.

Data transfer rate

• The speed which data can be transmitted from one device to another. Data rates are often measured in megabits or megabytes per second.

• Example – Transferring a video from a mobile device to a computer device.

• Platforms – World wide web, DVD, CD, Mobile device, email attachments.

File size• Resolution - is the term used to describe the number of dots, or pixels used to display an

image.• Higher resolutions mean that more pixels are used to create the image, resulting in a cleaner

better quality image.• Data rate - Data rate can refer to:Bit rateData signalling rateData rate unitsData transfer rate (disk drive)

• Frame rate - Frame rate is the frequency at which an imaging device produces images called frames.

• Key frame rate - The frequency with which key frames are placed into temporally compressed data sequences.

• Compressor - an electrical device which reduces the dynamic range of a sound signal.• Audio settings – allows you to play around and adjust the volume, pitch etc of sound.• Platforms – World wide web, presentations, mobile devices, DVD, CD, email attachents.

Aspect ratio (4.3, 16.9)

Aspect ratio is defined as the ratio of width to height of an image.Example – The measurement of an image.Platforms – World wide web, DVD, mobile device, email attachments.
