Method and apparatus for adaptive video sharpening

A video encoding system comprising:

• a pre-processor operable to perform processing operations on an input video sequence,
• a coding engine operable to perform bandwidth compression coding operations on a video sequence from the pre-processor;
• a statistics generator operable to derive statistics information of the input video sequence from the video sequence;
• and
• a transmission unit operable to transmit coded video data from the coding engine and compiled statistics information to a decoder.

A video decoding system comprising:

• a controller operable to separate statistics information and an encoded video sequence from a received video signal;
• a decoding engine operable to perform bandwidth decompression decoding operations on the encoded video sequence;
• a statistics interpreter operable to analyze the statistics information and to determine a process adjustment;
• and
• a post-processor operable to perform a post-processing operation according to the determined process adjustment.

A method of coding video data comprising:

• coding an input video sequence;
• collecting statistics information for frames of the input video sequence;
• and
• transmitting the statistics information value with the coded video sequence on a communication channel;
• wherein said transmitting comprises transmitting the statistics information according to an out-of-band channel.

A method of decoding video data comprising:

• separating an encoded video sequence and statistics information from a received video signal;
• decoding the encoded video sequence;
• analyzing the statistics information to determine a post-processing adjustment;
• adjusting a post-processing procedure based on the determined post-processing adjustment;
• and
• preparing the decoded video sequence for display by performing the adjusted post-processing procedure.
