IMPROVING SPATIAL QUALITY OF CODED PICTURES USING LAYERED SCALABLE VIDEO BIT STREAMS |
摘要 |
<p>A method of optimising the quality of a B picture by temporal scalability for an enhancement layer of a video bit stream, wherein the B picture B0.5 is predicted based on an SNR enhancement picture EI0 appearing in the highest enhancement layer of the bit stream. A prediction is achieved using foward prediction based on an enhanced picture already appearing in the same enhancement layer. As a result, information contained in the enhanced picture is not wasted.</p> |
