We are investigating a system that provides a computer graphics (CG)-based television program to viewers by sending a script to the terminal using CG and voice data. In this study, we assess the viewer satisfaction of CG programs produced using a text-based TV program making language (TVML). To verify whether CG programs can be used as a substitute for real programs, we conducted a comparative evaluation experiment between real and CG programs. In addition, to verify the best device for CG program viewing, we compared the same CG program viewed on a PC display and a smartphone. The results suggest that CG programs are acceptable substitutes for real news and information-related programs, and that smartphones might be more suitable than PC displays for viewing CG programs.
