Title
Improved Feedback Compensation Mechanisms for Multiple Video Object Encoding Rate Control
Abstract
This paper proposes new buffer and video object distortion feedback compensation mechanisms for efficiently dealing with deviations between the ideal and the actual behavior of video scene encoders when jointly encoding multiple arbitrarily shaped video objects in the context of compliant low-delay object-based MPEG-4 video coding. The proposed solution computes target buffer occupancies for each encoding time instant based on the amount and complexity of the video data to encode, and the bit allocation for each encoding time instant is feedback adjusted according to deviations relatively to this ideal behavior. Additionally, each video object bit allocation is also feedback adjusted based on the relative distortion of the various video objects in the scene. The proposed solution outperforms the non-normative MPEG-4 reference rate control algorithm for a wide range of bit rates and spatio-temporal resolutions, for typical test sequences.
