چکیده
Video prototypes (Mackay, 1988) use video to illustrate how users will interact with a new system. The goal is to refine a single system concept, making design choices that highlight and explore a particular design path. The technique appears similar to video brainstorming: Both involve small design groups who work together to create and interact with rapid prototypes in front of a video camera. Both result in video illustrations that render abstract ideas concrete and help team members communicate with each other. Both use paper & pencil prototypes or cardboard mock-ups to simulate novel technology. The critical difference is that video brainstorming expands the design space, by creating a number of unconnected collections of individual ideas, whereas video prototyping contracts the design space, by showing how a specific collection of design choices work together in a single design proposal.

FPGA Implementation and Verification System of H.264/AVC Encoder for HDTV Applications
For huge systems like video processing, FPGA prototyping plays an important role before taping out. In this paper, a verification system for H.264/AVC encoders with FPGA prototyping is proposed and implemented. An H.264 encoder with baseline profile of Level 3.2 was carried out with a clock frequency of 200MHz on a Xilinx Virtex-6 FPGA connected with DDR3 memory, which could satisfy real-time e...

متن کاملVideo Prototyping: a technique for developing hypermedia systems
Successful user interfaces create a interactive dialog between the user and the program that develops over time. Specific iterative design techniques, such as rapid prototyping and the Wizard of Oz, have proven particularly effective because they enable the program designers to test this interaction before the software is complete. This article describes a new technique called video prototyping...
