What is the fundamental math transformation used in video codecs (like MPEG, H.264, JPEG) to convert 8x8 spatial pixel blocks into frequency domain coefficients?
Option E is correct. DCT converts spatial image pixels into frequency domain coefficients, separating high-frequency detail for lossy quantization.
In video streaming, what technique dynamically adjusts the resolution and quality of the video stream in real-time based on the user's available network bandwidth?
Option C is correct. Adaptive Bitrate Streaming (HLS / MPEG-DASH) monitors connection speeds and switches between multiple encoded quality levels automatically.
In traditional 2D animation, what transparent cellulose acetate sheets were hand-painted with characters and placed over static background paintings?
Option A is correct. Cels (short for celluloid) were transparent sheets where characters were drawn and painted over static backgrounds.
Which animation principle states that secondary movements (e.g. a character whistling or swinging arms while walking) should support and enrich the main action?
Option A is correct. Secondary Action adds subordinate actions to complement and enrich the main action without distracting from it.
In video codecs, what is the term for eliminating spatial redundancy within a single static image frame using mathematical transforms?
Option B is correct. Intra-frame compression operates strictly within a single frame (spatial redundancy) without referencing other surrounding video frames.
