问题描述
我正在寻找一种 API，我可以用它来解码模拟信号的数字样本，根据 http://en.wikipedia.org/wiki/NTSC">NTSC 标准编码.我愿意考虑免费和商业选项.如果必须的话，我会自己滚动代码，但我想这段代码在过去的几十年里已经写了几十或几百次，所以我希望有一些东西在那里我可以适应.
I'm looking for an API that I can use to decode a digital sample of an analog signal, encoded according to the http://en.wikipedia.org/wiki/NTSC">NTSC standard. I'm willing to consider both free and commercial options. If I have to, I'll roll the code myself, but I imagine that this code has been written tens or hundreds of times in the past few decades, so I'm hoping there's something out there I can adapt.
你知道这样的 API 吗?
Do you know of such an API?
更新:似乎这段代码不一定像我希望的那样多次编写.显然，解决的问题是通过特定设备直接处理模拟输入.我正在寻找的是一种算法，它将模拟信号的直接数字样本作为输入(具有足够的分辨率来获取标准中指定的更改)并返回视频图片，类似于 http://www.physicsforums.com/archive/index.php/t-47403.html">这个人想要并且必须自己建造.
UPDATE: It seems that this code hasn't necessarily been written as many times over as I'd hoped. The solved problem, apparently, is dealing directly with the analog input via particular devices. What I'm looking for is an algorithm that takes as input a direct digital sample of the analog signal (with sufficient resolution to pick up the changes specified in the standard) and returns a video picture, similar to what http://www.physicsforums.com/archive/index.php/t-47403.html">this person wanted and had to build himself.
推荐答案
我知道 GNU Radio 存在一些用于此任务的代码，但我不知道它是否曾经通过黑白接收:.
I know that some code for this task exists for GNU Radio, though I don't know if it ever got past black&white reception:.

还有一个 GNU Radio ATSC 收发器更完整，但不是您想要的.
There is also a GNU Radio ATSC transceiver that is more complete, though not what you were looking for.
