What is Multimedia?
Answer
Multimedia is the integration of multiple forms of media, such as text, audio, graphics, animation, and video, into a single interactive information system. It combines these diverse elements to convey information or entertainment in a more engaging and effective manner than traditional single-media formats. The key characteristic of multimedia is its interactivity, allowing users to control the flow and delivery of the content.
What do you mean Composite Video Signal?
Answer
A Composite Video Signal is an analog video transmission format that combines all the necessary video information—including luminance (brightness), chrominance (color), and synchronization pulses—into a single electrical signal. This signal is typically transmitted over a single cable, often using an RCA connector. Because all components are combined, the signal is prone to interference, which can result in lower image quality compared to component or digital video signals.
