This study presents a fast video transcoding architecture that overcomes the complexity of different coding structures between H.264/AVC and SVC.

Simple Closed-Loop Architecture: During the sampling time, the drain and source voltage of MOS switch are closed to ground. Thus the charge injection and cloc k feedthrough introduce an offset voltage at the output and is independent of the input …

To implement integral control you use an approximation to the integral. The integral computation is updated by adding an area equal to the latest measurement multiplied by the sampling period between measurements (the width of the rectangle).

Closed loop transcoder: This transcoding architecture aims at eliminating the mismatch between the predictions by approximating the cascaded pixel domain transcoder. This is achieved through...

Thanks to recent approximations of the entropy and distortion functions, we propose accurate and fast bit allocation schemes appropriate for the open-loop- and closed-loop-based stereo...

Open-loop transcoding architectures can be used for H.264/AVC-to-SVC transcoding with a low complexity, although these architectures suffer from drift artifacts. Closed-loop transcoding, on the other hand, requires a higher complexity.

Example: Design an arrangement with a stable voltage gain of 100 using a high-gain active amplifier. Determine the effect on the overall gain of the circuit if the voltage gain of the active amplifier varies from 100,000 to 200,000. ...Negative feedback – an example...

Hopen refers to the open loop transfer function, which describes the behavior of a plant. It relates controller input u to system state x. Hclose refers to the closed loop transfer function, which describes the behavior of the entire system. It relates the reference input r to the system output y.

Sep 1, 2011 · To reduce the H.264/AVC-to-SVC transcoding complexity, we propose a transcoding architecture which combines optimized closed- and open-loop transcoding techniques.
