对于iPhone应用程序所需的AAC许可证？ [英] AAC license required for iPhone app?

问题描述

AAC是这是一个音频codeC设计为MP3格式的继任，AAC一般达到更好的音质比同类比特率的MP3。 （在维基百科上 AAC）。

然而，类似于MP3，AAC的codeC的部分专利，这意味着在所有的情况下，你不能简单地使用这些codeCS未做肯定你被授权这样做。结果
这也是真实的，如果你开发了自己的EN codeR或去$ C $铬。这是因为写一个自己的EN codeR或去codeR释放你只能从版权问题和软件许可证（因为你拥有版权），但它并没有从专利强加于你的要求中解脱出来。

我是否需要获取许可证为我的iPhone应用程序，它可以连接code和/或去code AAC文件？

解决方案

只要你使用集成的EN codeRS和/或去codeRS，你并不需要获得自己的使用授权在iPhone AAC codeC。

我已经联系 vialicensing.com 关于这一点，他们的回答是：

  

如果您的应用程序使用的iPhone集成了去codeR，无许可证
  需要。但是，如果你提供一个单独的去codeR作为其一部分
  您的产品，您将需要获得每单位发运许可证。

此外，还设有约codeRS：

  

这也适用于记录使用集成恩的codeR
  苹果手机。提供了一间codeR和/或去codeR什么要求
  专利许可。如果一个产品依赖于一体的综合性卫浴codeR /德codeR
  在一个设备，它是被需要以满足设备品牌所有者
  许可义务。

不过，因为这是一个法律话题，而不是编程的话题，您应通过授权，如果您对具体应用的任何不确定性联系。

AAC is an audio codec which was "Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at similar bit rates." (AAC on Wikipedia).

However, similarly to MP3, parts of the AAC codec are patented, which means you can't simply use these codecs in all situations without making sure you are licensed to do so.
This is also true if you developed your own encoder or decoder. This is because writing an own encoder or decoder frees you only from copyright issues and software licenses (because you hold the copyright), but it doesn't free you from requirements imposed on you by patents.

Do I need to acquire a license for my iPhone app, which can encode and/or decode AAC files?

This question is helpful to many developers, but it is not a good example of an appropriate question for Stackoverflow. Read and learn from this post, but please do not use it as evidence that you can ask similar questions.

解决方案

As long as you use the integrated encoders and/or decoders, you do not need to acquire your own license for using the AAC codec on the iPhone.

I've contacted vialicensing.com about this and they replied:

If your app uses the integrated decoder of the iPhone, no license is required. If however, you are providing a separate decoder as part of your product you will need to obtain a license for every unit shipped.

Moreover, also about encoders:

that also applies to recording using the integrated encoder of the iPhone. Providing an encoder and/or decoder is what requires the patent license. If a product relies on the integrated encoder/decoder in a device it is the device brand owner which is required to fulfill the license obligation.

Still, because this is a legal topic rather than a programming topic, you should contact via licensing if you have any uncertainties about your specific app.
