摘要

在某些情况下,如网络带宽有很多限制时,数字电视(DTV)上的完整联播可能很难实现。在这种情况下,一个常见的解决办法是将联播中重复节目的数量限制到最低限度。然而,这种做法减缓了向新一代的迁移。本文分析了产生这种延迟的原因,并提出了一种提高同播效率的技术。本文针对DVB-T网络中MPEG-2 SD向H.264 HD广播的迁移,提出了一种加速迁移的高效解决方案。

Aggressive joint compression for DTV simulcast
A complete simulcast on digital TV (DTV) can be complex to implement in some scenarios, such as when the network bandwidth has many limitations. A common solution in such scenarios is to limit the number of duplicate programmes in the simulcast to a minimum. However, this practice slows down the migration to a new generation. This article analyses the causes of this delay and proposes a technique to improve the efficiency of the simulcast. Focusing on the migration from MPEG-2 SD to H.264 HD broadcasts in DVB-T networks, the article presents an efficient solution that can accelerate the transition period.
