Types of BISS Encoders

• BISS C Encoders:

  For digital synchronization, the BISS (Broadcast and Internet Security System) C encoder uses a clock signal with the Zero Bit Transmission (ZBT). It transmits the synchronization signal along with the data stream, where the synchronization of sub-channel can be obtained directly from the main channel. It has a reduced jitter compared to the BISS link which provides better signal quality. This benefits the DTH (Direct-to-Home) reception system, and satellite distribution. When comparing the BISS-1 to BISS-C, the later offers enhanced security and improved signal quality for digital broadcast systems.

• BISS-S Encoders:

  BISS-S that is identified as Simple system uses encryption, unlike the other BISS systems. It will prevent unauthorized access or signal reception and allows for system transmission. Both encoders have a mutual relationship in that BISS-1 systems are decoded using the BISS-S. BISS-S can not be decoded by a BISS-1 system. Only with the same key, the signals from both BISS-1 and BISS-S can be mutually decoded. They can also not be decoded by a BISS-2 or BISS-C system.

• BISS-1 Encoders:

  The BISS-1 encoder is based on a simple symmetric key system. In this system, the same key is used for encryption and decryption. Using this key, the signal can be encoded and then decoded at the receiving end. BISS-1 provides a basic level of security through encryption, preventing unauthorized access to the transmitted signal. However, it does not support key management, which means that the same key is manually distributed and managed across all points of the system.

• BISS-2 Encoders:

  The BISS-2 encoder enhances the security features of the BISS-1 system by introducing a key management mechanism. In this system, keys are generated, distributed, and managed through a secure infrastructure, ensuring that they are used consistently and securely across all points of the system. BISS-2 also provides replay protection, which prevents the same key from being used multiple times for decryption. This system has distinguishing features like its algorithm, key management mechanism, and no replay attacks. It strengthens the security measures against unauthorized access and enhances the system's integrity by preventing replay attacks.

• BISS-4 Encoders:

  The BISS-4 encoder is a technology that increases the security system of broadcast signals. It ensures two things. First, it makes sure that messages sent in sequence (in a chain) arrive in the correct order. Second, it uses four different secret keys instead of just one. These keys are used at different stages to encrypt and decrypt the signal. Using four keys is better than using just one because it helps keep the keys more secure. It reduces the chance of one key being exposed. BISS-4 encoders also follow the rules of the BISS-2 system. This makes sure that only authorized users can decode the signals.

Function and features of BISS encoders

BISS encoders have crucial security, functionality, and operational features. Here are some of the key ones:

• Signal security: The primary purpose of BISS is to provide some level of data security to prevent data leakage during transmission. BISS encoders use unique encryption keys to secure signals. Only authorized users with the correct keys can access the signal. This enables broadcasters to operate in accordance with strict confidentiality standards and to prevent unauthorized access to sensitive information.
• Key management: BISS encoders have advanced key management capabilities that enable simple distribution, storage, and rotation of encryption keys. Broadcasters can manage keys efficiently, ensuring that only authorized personnel have access to keys and maintaining the security of encrypted signals.
• Compliance with regulations: BISS encoders comply with industry regulations and standards, such as those set by the European Telecommunications Standards Institute (ETSI) and the Institute of Electrical and Electronics Engineers (IEEE). Compliance ensures that encoders meet the necessary technical requirements for signal protection in broadcasting environments.
• Contingency protocols: BISS has contingency protocols that allow quick switching to backup signals in case the primary signal fails. These contingency protocols ensure operational continuity by using automated failover procedures that detect signal outages and switch to backup signals.
• Real-time monitoring : Monitoring tools to keep track of signal quality, system performance, and the status of encryption and decryption processes in real-time. These tools provide alerts and notifications for potential issues or anomalies, allowing broadcasters to take corrective measures promptly.
• Deep Insights: A BISS encoder provides insights into signal transmission parameters such as latency, jitter, and packet loss. This information helps broadcasters assess the reliability and integrity of encrypted signals, enabling them to make informed decisions for signal distribution.
• Scalability and integration: BISS encoders are designed to scale easily to meet the growing demands of broadcasters. They typically come in various models and configurations to accommodate different signal types, encryption strengths, and channel counts. Broadcaster ecosystems can integrate seamlessly with encoding systems, aiding in workflow optimization and expanding functionality.

Scenarios of BISS encoders

Despite how different BISS encoder models may be used in various industries, they all share a common underlying principle for encrypted broadcast transmission. However, certain applications can be broadly categorized to provide an overview of the diverse industries where encoders are employed:

• Broadcasting: BISS is primarily used in broadcasting applications, including television and radio broadcasting. BISS encoders encrypt the broadcast signal to prevent unauthorized access to the content, especially for premium or sensitive programs. BISS encryption secures satellite, cable, and terrestrial broadcast transmission.
• Distribution of Broadcasts: BISS encryption is used to secure the distribution of broadcast signals from one point to another within the broadcasting network. For example, BISS can encrypt the feed from a studio to a transmitter or the contribution link between two broadcast facilities. This ensures the content remains protected even during distribution before it reaches the final audience.
• Content Protection: BISS encoder is paramount in preventing piracy and protecting licensed content. BISS encryption helps broadcasters and rights holders safeguard their intellectual property by ensuring that encrypted content cannot be accessed without proper authorization.
• Sports Events and Other Sensitive Programming: High-profile programming, such as live coverage of sports events, news programming, and other sensitive or exclusive content, often requires BISS encryption to protect it. These programs can attract unauthorized viewing or interception, necessitating stronger security measures like BISS encryption to prevent breaches.
• Contribution Links: In broadcasting, contribution links refer to the transmission paths used to send program feeds between production facilities, such as OB Vans (Outside Broadcast Vans) transmitting live coverage from a sports event location to a studio for further processing before broadcasting. BISS encodes play an important role in securing these links so that broadcasters can ensure the integrity and security of their programming before it reaches the audience.
• Cable Headends: Cable headends are facilities where cable television signals are received from satellites or other sources, decoded for distribution on the cable system, and then transmitted over the cable network to subscribers' homes. BISS encodes can be used at cable headends to encrypt certain channels or programs to protect their content rights.
• Television Production: BISS is sometimes used in television production environments to secure feeds from cameras, editing suites, or other production equipment during live or recorded production sessions. This ensures that unbroadcasted content is kept secure until it is ready for airing.
• Data Streaming: Besides video and audio broadcasting, BISS encryption can protect data streams transmitted via satellite or other transmission mediums. This includes protecting sensitive data that may be transmitted alongside broadcast signals to ensure its confidentiality and integrity.

How to Choose BISS Encoders

When selecting a BISS encoder for purchase, which is a BISS decoder for commercial uses, there are several important factors to consider to ensure it meets specific needs and requirements.

• Applications: The first thing is to consider the application. Knowing what will be encoded makes choosing the right device easier. Is it for video conferencing, broadcasting, security, or streaming?
• Channels: Multichannel encoders exist, but if one is sure to work with a single channel, a single-channel encoder will be more cost-effective.
• Outputs: Some encoders have multiple output ports and can simultaneously send different streams to destinations; if the user needs this feature, the device will need to have multiple output ports.
• Provider: A reputable provider is essential for any tool. Knowing that there is an after-sale service and that someone can help if there is a problem is very important.
• Cost: While cost may be the last item on the list, it is worth noting that it influences many of the features above. It is essential to set a budget and stick to it while considering all the requirements within that budget.
• Protocol Support: It is critical that the encoder support the transmission protocol to which the receiving equipment will adhere. Among the standards are RTSP, HTTP Live Streaming (HLS), Real-Time Streaming Protocol (RTSP), and Real-Time Messaging Protocol (RTMP).
• Integrated Systems: Another factor to consider is whether one wishes to integrate other systems or the BISS encoder with other systems. Integrated encoders with additional functionality may be necessary.
• Input Ports: It is essential to understand what equipment will connect to the encoder. Devices to be connected should be compatible with the encoder's input ports. Many encoders have input ports, including HDMI, USB, and AV.
• Enclosure: Outdoor encoders need weatherproof enclosures, protection against rain, and UV-resistant materials. Indoor encoders are designed for encased equipment.
• Size: Space constraints must be considered since encoders require storage space.
