Adaptive Stream
Why we need to Recompose?
- Reduction (real-time cuts, browsing)
- Stream Augmentation (add sound, caption, logos etc.)
- Editing (stream switching, non-linear editing)
- Pel Manipulation (fades, wipes special effects)
- Transcoding (adjust format, bit-rates, levels, profiles).
- Transmultiplexing (creating new transport streams from elements).
Paradox: Compression vs. Code Flexibility
- What kind of decomposition can be used that gives good quality at all levels of resolution and yet is concise?
- What signal packing methods might be used to produce data streams that can be easily taken apart by decoder and adapters?
