Method and apparatus for video coding with adaptive clipping
In a particular implementation, a clipping bound may be different from the signal bound. For example, to derive the upper clipping bound, a reconstructed sample value corresponding to original sample value Y is estimated to be Y+Δy. Thus, for a candidate upper clipping bound x, the difference between the clipped value and the original value is calculated as min(Y+Δy, x)−Y.

The distortion may first decrease (or maintain the same) and then increase, and the turning point is chosen as upper clipping bound M′. Similarly, the lower clipping bound m′ can be chosen. For more effective clipping, the color components may be transformed such that the transformed color components may be more tightly enclosed by a box defined by the clipping bounds. |

Event driven route control
Embodiments provide system and methods for a DDoS service using a mix of mitigation systems (also called scrubbing centers) and non-mitigation systems. The non-mitigation systems are less expensive and thus can be placed at or near a customer's network resource (e.g., a computer, cluster of computers, or entire network). Under normal conditions, traffic for a customer's resource can go through a mitigation system or a non-mitigation system. When an attack is detected, traffic that would have otherwise gone through a non-mitigation system is re-routed to a mitigation system. Thus, the non-mitigation systems can be used to reduce latency and provide more efficient access to the customer's network resource during normal conditions. Since the non-mitigation servers are not equipped to respond to an attack, the non-mitigation systems are not used during an attack, thereby still providing protection to the customer network resource using the mitigation systems. |
