Multiple parallel encoders and statistical analysis thereof for encoding a video sequence

A method of encoding a sequence of video frames comprising:

• encoding the sequence of video frames employing multiple parallel connected encoders, each encoder of the multiple encoders receiving for encoding identical video data of the sequence of video frames, wherein each encoder of the multiple encoders employs a set of encode parameters, each set of encode parameters comprising multiple types of encode parameters, at least one type of encode parameter of the sets of encode parameters being varied between at least two encoders of the multiple encoders connected in parallel;
• selecting one set of encode parameters from the sets of encode parameters employed by the multiple parallel connected encoders which best meets an encode objective;
• outputting a bitstream of encoded video data encoded from the sequence of video frames using the one set of encode parameters;
• and
• wherein said selecting further comprises automatically adapting an encode parameter in one or more encoders of the multiple encoders when no set of encode parameters of the sets of encode parameters employed by the multiple encoders produces an encoded result which meets the encode objective.

At least one program storage device readable by a machine, tangibly embodying at least one program of instructions executable by the machine to perform a method of encoding a sequence of video frames, the method comprising:

• encoding the sequence of video frames employing multiple parallel connected encoders, each encoder of the multiple encoders receiving for encoding identical video data of the sequence of video frames, wherein each encoder of the multiple encoders employs a set of encode parameters, each set of encode parameters comprising multiple types of encode parameters, at least one type of encode parameter of the sets of encode parameters being varied between at least two encoders of the multiple encoders connected in parallel;
• selecting one set of encode parameters from the sets of encode parameters employed by the multiple parallel connected encoders which best meets an encode objective;
• outputting a bitstream of encoded video data encoded from the sequence of video frames using the one set of encode parameters;
• and
• wherein said selecting further comprises automatically adapting an encode parameter in one or more encoders of the multiple encoders when no set of encode parameters of the sets of encode parameters employed by the multiple encoders produces an encoded result which meets the encode objective.
