All Satellite Dish Channel PowerVU Keys & Biss Key

What is the BISS key?

BISS(Basic Interoperable Scrambling System) for satellite signal scrambling developed by Europeans broadcasting union (EBU) and devices manufacturer. BISS is a system used on private video feeds shared via satellite between organizations. BISS : Basic Interoperable Scrambling System, usually known as BISS is a satellite signal scrambling system developed by the European Broadcasting Union and a consortium of hardware manufacturers. Organizations like the EBU/Eurovision use BISS to distribute their content to partners securely.

Prior to its development occasional use satellite news feeds were transmitted either using proprietary encryption methods (e.g. PowerVu) or without any encryption. Unencrypted satellite feeds allowed anyone with the correct equipment to view the program material. BISS was an attempt to create an "open platform" encryption system which could be used across a range of manufacturers equipment. Proprietary encryption methods were determined by encoder manufacturers and placed major compatibility limitations on the type of satellite receiver (IRD) that could be used for each feed.

Biss Control Words are static and are only changed by the Broadcasters when they need to. With this encryption, there is no decoding process as such just the final Biss Control Word.

PowerVu is a conditional access system for digital television developed by Scientific Atlanta. It is used for professional broadcasting, notably by Retevision different Network. It is also used by cable companies to prevent viewing by unauthorized viewers and non-cable subscribers.

PowerVu has decoders that decode signals from certain satellites for cable distribution services. These decoders can also be used satellite receivers if properly configured. PowerVu is considered very secure since it uses a complicated system to authorize each PowerVu receiver and trace its history of ownership and usage citation needed. Most PowerVu users are professional cable or satellite companies using the service and equipment for signal redistribution because regular users cannot afford it. A consumer PowerVu subscription TV service is available for c band dish users in the United States.

Simple BISS works by the two parties sharing a common key, the sender then encrypts the broadcast and the receiver uses the key to decode that video.

There is also an enterprise version of BISS where the broadcaster will encrypt the stream and the system will send the content key using secret means to decoders who are pre-registered with the BISS headend.

BISS钥匙是什么？

由欧洲广播联盟（EBU）和设备制造商开发的用于卫星信号加扰的BISS（基本互操作加扰系统）。 BISS是一种用于组织之间通过卫星共享的私人视频提要的系统。 BISS：基本互操作加扰系统，通常称为BISS，是由欧洲广播联盟和硬件制造商联盟开发的卫星信号加扰系统。像EBU / Eurovision这样的组织使用BISS来安全地将其内容分发给合作伙伴。

在开发之前，偶尔会使用专有的加密方法（例如PowerVu）或不进行任何加密来传输卫星新闻提要。未经加密的卫星馈送使任何拥有正确设备的人都可以观看节目材料。 BISS试图创建一种可在各种制造商的设备上使用的“开放平台”加密系统。专有的加密方法由编码器制造商确定，并且对可用于每种馈送的卫星接收器（IRD）的类型设置了主要的兼容性限制。

Biss控制字是静态的，仅在广播员需要时才更改。使用这种加密，就没有解码过程，就像最终的Biss控制字一样。

PowerVu是由科学亚特兰大开发的数字电视条件接收系统。它用于专业广播，尤其是Retevision不同的网络。有线电视公司还使用它来防止未经授权的观看者和非有线电视订户观看。

PowerVu具有解码器，可解码来自某些卫星的信号以进行电缆分配服务。如果配置正确，这些解码器也可以用作卫星接收器。 PowerVu被认为是非常安全的，因为它使用复杂的系统来授权每个PowerVu接收器并跟踪其所有权历史和所需的使用引用。大多数PowerVu用户是专业的电缆或卫星公司，他们使用服务和设备进行信号重新分配，因为普通用户买不起。消费PowerVu订阅电视服务可用于美国的c带碟用户。

简单的BISS由双方共享一个共同的密钥来工作，然后发送方对广播进行加密，接收方使用该密钥对该视频进行解码。

还有BISS的企业版，广播商将对该流进行加密，并且系统将使用秘密方式将内容密钥发送给预先在BISS头端注册的解码器。
