**8. Future work**

The methodologies outlined in the chapter are just a single contribution to the overall framework of quality standards for task-based video. It is necessary to define requirements starting from the camera, through the broadcast, and until after the presentation. These requirements will depend on scenario recognition.

So far, the practical value of contribution is limited. It refers to limited scenarios. The presented approach is just a beginning of more advanced interesting framework of objective quality assessment, described below (Leszczuk, 2011).

Further steps have been planned in standardization in assessing task-based video quality with relation to QART initiative. Stakeholders list has been initially agreed and action points have been agreed. The plans include: quantifying VQiPS' GUCs, extending test methods (standardization of test methods and experimental designs of ITU-T P.912 Recommendation), measuring camera quality, investigating H.264 encoders, investigating video acuity as well as checking results' stability. The final outcome should be to share ideas on conducting joint experiments and publishing joint papers/VQEG reports, and finally, to submit joint standardization contributions. Plans/next steps for standardizing test methods and experimental designs include verification of issues like: subliminal cues, Computer-Generated Imagery (CGI) source video sequences, automated eye charts as well as subjects' proficiency. The agreed tasks include verifying requirements, refining methods/designs and, finally, making subjective experiments both more accurate and feasible.
