The on-the-wire encoding of CORBA contains a large amount of redundancy, but the protocol does not support compression. This leads to poor performance over wide-area networks.

CORBA的线上编码包含大量的冗余，但是协议并不支持压缩，这导致了大面积网络的性能缺陷。

However, it requires a huge amount of computations and long time of encoding.

但这种方式存在大量的计算量，编码时间长。

However, along with its performance improved, it has brought a tremendous amount of computing, so it is difficult to use its source code directly to achieve the real-time encoding and decoding.

然而其性能提高的同时却带来了巨大的运算量，使得很难直接运用其源代码来达到实时编解码。

Three years ago Sony began developing technology that grabs the video signal before it goes into the hub and, rather than encoding the whole thing, as the duopolists do, encodes just the right amount, between 2% and 10%, to thwart piracy.

FORBES: Sony busts up the powerful cable-box duopoly.
