Frequency adjustments for event organizers
The upcoming transition from DVB-T2 to DVB-T in terrestrial television may pose challenges for the event industry, particularly in larger metropolitan areas. While many countries are maintaining or upgrading to DVB-T2, the change is necessary for efficient frequency planning and coordination.
## Solutions for Frequency Planning and Coordination
### 1. Adopting Hybrid Delivery Models
Implementing a hybrid delivery model that combines broadcast, telecom, and IP-based systems can enhance flexibility and resilience. This approach is supported by organisations like the DVB Project and DTVKit, which focus on standards-based, interoperable systems.
### 2. Utilizing Advanced Technologies
- DVB-T2 and SFN: Technologies like the Virtuoso CP4400 TS Processor from Nevion are designed for DVB-T2 Single Frequency Networks (SFN), which can help in efficient frequency management and regional adaptations. - IP-Based Systems: Solutions like DVB-NIP and ATSC 3.0 enable IP-based video delivery, which can be integrated with existing broadcast systems to enhance flexibility and on-demand services.
### 3. Collaboration and Standardization
- Embracing standards like DVB-T2 ensures interoperability and facilitates easier frequency planning across different regions. - Collaboration between broadcasters, event organisers, and technology providers is crucial for managing frequency planning effectively.
### 4. IP-Based and OTT Services
- Offering content through Over-the-Top (OTT) platforms can help manage frequency usage by providing alternative distribution channels. - Interactive services, similar to those offered by Rai, can enhance viewer engagement without increasing the demand on broadcast frequencies.
## Entertainment Branch Considerations
For the entertainment branch, managing frequency planning involves ensuring seamless content delivery across various platforms. This can be achieved by:
- Adopting versatile technologies that support both broadcast and IP-based delivery models. - Enhancing viewer experience by offering on-demand services and interactive applications to complement live broadcasts. - Collaborative planning with frequency regulators and other stakeholders to ensure efficient use of available frequencies.
The switch to DVB-T will permanently affect wireless microphones, audio systems, and other production tools in the entertainment industry. The range between 470 and 694 Mhz, previously used for these devices, will remain crucial. The event industry may face additional challenges during the transition, with large-scale events potentially having to be cancelled due to the limited availability of frequencies for wireless microphones and other equipment.
To mitigate these challenges, initiatives like SOS-Save-Our-Spectrum.org are warning about the threat to wireless products due to frequency sales. The Institute for Radio Technology is providing software to help associations and their members navigate the challenges of the transition, aiming to address the issue of interference radiation during the transition.
Consistent exchange of information among technicians will be necessary to ensure a smooth transition. With the right strategies and collaborative efforts, the event industry can adapt to the changes in broadcast standards and manage frequency planning effectively. However, specific solutions may vary based on regional regulations and technological availability.
Data-and-cloud-computing technology can be utilized to facilitate collaboration and standardization among broadcasters, event organizers, and technology providers, improving the management of frequency planning and coordination during the transition from DVB-T2 to DVB-T. Advanced technologies like DVB-NIP and IP-based systems, supported by standards-based, interoperable systems such as those promoted by the DVB Project and DTVKit, can help enhance flexibility and resilience, ultimately aiding in efficient frequency planning and coordination.
