  • Discussion about video WM algorithm:

- Block based differential DCT algorithm
- Embedding
- Watermark error
- Quality
- Robustness

  • Discussion about the structure and required capacity of meta-data
  • IQIM and SpQIM embedding methods (spreading information across multiple coefficients by quantization of vector length)
  • Intelligent distribution of information between more or less fragile bits.
  • Embed bit-stream instead of images and investigate BER
  • Implementing the algorithm in DPCM domain vs. ordinary frame domain
  • Adopting color spaces
  • Structure of WM (redundancy)
