Study Notes
Desirable Features for a Multimedia System
- Very High Processing Power is required to deal with large data processing and real-time delivery of media, and special hardware is often used.
- A Multimedia Capable File System is needed to deliver real-time media, such as video and audio streaming, and special hardware/software like RAID technology is required.
- Data Representations should support multimedia, be easy to handle, and allow for compression/decompression in real-time.
- Efficient and High I/O is necessary for efficient and fast input/output to the file subsystem, allowing for real-time recording and playback of data.
- A Special Operating System is required to allow access to the file system and process data efficiently and quickly, with features like direct transfers to disk, real-time scheduling, and fast interrupt processing.
- Large Storage and Memory units are necessary, with large caches and high-speed buses for efficient management.
- Network Support is required, often using client-server systems and distributed systems.
Components of a Multimedia System
- Capture devices: Video Camera, Video Recorder, Audio Microphone, Keyboards, mice, graphics tablets, 3D input devices, tactile sensors, and VR devices.
- Digitising Hardware is needed.
- Storage Devices: Hard disks, CD-ROMs, DVD-ROM, etc.
- Communication Networks: Local Networks, Intranets, Internet, Multimedia or other special high-speed networks.
- Software Tools: user-friendly tools are needed to handle media, design and develop applications, and deliver media.
Characteristics of a Multimedia System
- A Multimedia System is computer-controlled.
- A Multimedia System is integrated.
- The information handled is represented digitally.
- The interface to the final presentation of media is usually interactive.
Challenges for Multimedia Systems
- Distributed Networks pose challenges.
- Temporal relationships between data must be maintained, including rendering different data at the same time, sequencing, and synchronisation.
Key Issues for Multimedia Systems
- How to represent and store temporal information.
- How to maintain temporal relationships during playback/retrieval.
- Data must be represented digitally through Analog-Digital Conversion, Sampling, etc.
- Large Data Requirements necessitate bandwidth, storage, and data compression.
Introduction to Multimedia Systems
- Multimedia refers to the representation of computer information through audio, video, animation, and traditional media.
- A good general working definition for Multimedia is the field concerned with the computer-controlled integration of multiple media sources.
Multimedia Application Definition
- A Multimedia Application is an application that uses a collection of multiple media sources.
What is HyperText and HyperMedia?
- Hypertext is text that contains links to other texts.
- HyperText Navigation is non-linear, with implications for layout and organisation of material.
- HyperMedia is not constrained to be text-based and can include other media, such as graphics, images, and continuous media like sound and video.
Multimedia Applications
- Examples of Multimedia Applications include the World Wide Web, Multimedia Authoring, and others.
