Abstract—In order to improve coding compression and display quality in bitstream playback, an H.264, with an “adaptive transform with variable block” (ATVB), is able to achieve this. However, these added compression and display benefits are offset by the demand for double the computation power requirements. In addition to this computing power increase an extra round of Motion Estimation (ME), when using 4x4 or 8x8 a transform module is also required. Therefore, this paper proposes a savvy hypothesis to reduce the computation requirements between 30%-45% using ATVB with 0.25db display distortion and 2.5% bitrate increment.
