摘要

反映高质量视频需求的先进T-DMB (AT-DMB)正在开发，采用分层调制，以增加数据负载。在AT-DMB系统的基础上，提出了一种以高空间分辨率提高视频质量的方法。该方法采用H.264/AVC修正案3可扩展(SVC)技术，在保证T-DMB向后兼容的同时，还支持当前服务的高空间分辨率。实验结果表明，与传统的T-DMB和替代方法相比，该方法在提供高空间分辨率视频方面具有优势。

Advanced T-DMB with hierarchical modulation and scalable video coding

Reflecting the demand for a high quality video, Advanced T-DMB (AT-DMB) adopting a hierarchical modulation is being developed in order to increase the data payload. Based on the AT-DMB system, this paper proposes a method to provide the increased video quality with a high spatial resolution. By using the emerging H.264/AVC amendment 3 scalable extension (SVC), the proposed method supports a high spatial resolution as well as the currently serviced spatial resolution while retaining the backward compatibility to T-DMB. In the experimental results, benefits are shown in comparison with the conventional T-DMB and alternative methods to provide a high spatial resolution video.
