The invention is directed to a system and method for the creation and management of advertising inventory utilizing associated metadata. The resilient contact piece is cantilevered back from the resilient supporting piece and then is bent forward. A baseband processor receives the trigger signal from the signal waveform detector and captures the desired signal. For this re-calculation of the first DCT coefficients, the motion compensation module inputs second DCT coefficients of neighboring blocks in the inter-frame, and calculates partial DCT coefficients, using significant ones of the second DCT coefficients of the neighboring blocks.
