Abstract:
A method of determining a maximum permissible key frame distance for use in encoding image frames in a video sequence comprising encoding a plurality of video test sequences, each video test sequence having a respective noise level, where each video test sequence is encoded using a respective quantization parameter and a plurality of key frame distances is disclosed. For each video test sequence, an output bitrate is determined for each key frame distance. For each combination of noise level, quantization parameter, and key frame distance, the determined output bitrate is stored and a maximum key frame distance at which output bitrate decreases in response to an increase in key frame distance is identified as maximum permissible key frame distance. A method of encoding image frames in a video sequence is also disclosed, as well as a system, a camera and a computer program product for performing the methods.

Claim (Index 16):
The camera of  claim 14 , wherein the key frame distance determination module is further arranged to select the maximum permissible key frame distance, the key frame distance determination module using a maximum key frame distance selection arrangement, said arrangement comprising:\n a test video sequence evaluation module arranged to encode a plurality of video test sequences, each video test sequence having a respective noise level, wherein each video test sequence is encoded using a respective quantization parameter and using a plurality of key frame distance, and for each video test sequence determine an output bitrate for each key frame distance; a memory module arranged to store, for each combination of noise level, quantization parameter, and key frame distance, the determined output bitrate; and a selection module arranged to, for each such combination of noise level and quantization parameter, identify as maximum permissible key frame distance a maximum key frame distance at which output bitrate decreases in response to an increase in key frame distance.
