1. A video signal processing method for processing video signals containing video material by a server, the server executing instructions to perform the method comprising:
- separating video material from the video signals into segments, the video material comprising a plurality of frames;
calculating a number of new feature points per frame of the video material;
determining, for each segment, whether the number of new feature points exceeds a threshold value;
selecting, based on the determination, one of a plurality of transcoding hints states; and
transcoding the video material according to the selected one of a plurality of transcoding hints states.

Abstract
An audio/video (or audiovisual, “A/V”) signal processing apparatus and method for extracting a compact representation of a multimedia description and transcoding hints metadata for transcoding between different (e.g., MPEG) compressed content representations, manipulating (e.g., MPEG compressed) bitstream parameters such as frame rate, bit rate, session size, quantization parameters, and picture coding type structure (e.g., group of pictures, or “GOP”), classifying A/V content, and retrieving multimedia information.
