Transferring traceable time to BPS-enabled ATSC 3.0 station - $15
Date: March 21, 2025Topics: 2025 BEITC Proceedings, Broadcast Positioning System (BPS): Resilience and PrecisionBroadcast Positioning System (BPS) necessitates precise time synchronization across TV stations, utilizing a shared time reference and their fixed locations for triangulation and reliable positioning, with time over fiber solutions connected to trusted timing sources serving as a viable method for maintaining accurate synchronization. In this paper, we present a concept to link BPS leader stations to timescales maintained by National Metrology Institutes (NMIs) using High Accuracy White Rabbit synchronization through optical networks.

Transforming Team Collaboration with Avatars: Enhancing Productivity in Content Creation in Broadcasting - $15
Date: March 21, 2025Topics: 2025 BEITC Proceedings, Production Advancements: Avatars and Immersive ContentIn the fast-paced world of broadcast and media, teams must collaborate efficiently and create content quickly to remain competitive. Avatar technology offers an innovative solution, enabling team members to stay connected even when they are unable to be physically present. By stepping in to summarize past meetings and capture key insights, avatars bridge communication gaps and ensure continuity, allowing teams to resume their work without the need for lengthy catchups. This approach enhances decision-making and streamlines workflows, keeping teams aligned and productive. In addition to avatars, the integration of intuitive tools for video editing, content creation, and subtitling empowers teams to produce high-quality content without specialized skills. These tools support multiple languages, enabling broadcasters to reach a diverse, global audience. With simplified video clipping, merging, and subtitling processes, teams can adapt and release content more quickly, making their workflows more efficient and responsive to industry demands. This combination of avatar-driven collaboration and user-friendly content tools optimizes production time, enhances engagement, and ensures a smooth workflow, even when team schedules do not align. It allows broadcasters to work smarter, integrating technology into the creative process. This approach empowers teams to create exceptional content, collaborate seamlessly, and meet the growing demands of today’s dynamic media landscape.

Transitioning a Network Operations Center from HD-SDI to IP - $15
Date: April 26, 2020Topics: 2020 BEITC Proceedings, IP Conversion: Broadcasters' Research & RecommendationsThe PBS Network Operations Center (NOC) provides the content aggregation and delivery for the Public Television Community.?Like many other media facilities, the NOC was built as an HD-SDI-based facility.?We have added IP-based “islands” to the facility as the technology has advanced.?We have now reached the stage where demands for a more tightly integrated workflow to efficiently serve the needs of over-the-air and OTT delivery require that we move to a fully IP-based facility.?This includes moving a number of our on-premise functions to the “public cloud,”?integrating the cloud functions seamlessly with our on-premises functions, and providing our operations and maintenance staff the ability to easily monitor all the diverse elements of this “system.”?This project is a work in progress.?We will provide a snapshot?of where we are in this process, and then present a summary of the lessons learned.?This summary should provide the basis for others to structure their own facility transitions.

Transitioning Broadcast to Cloud - $15
Date: April 26, 2020Topics: 2020 BEITC Proceedings, Designing Cloud-based FacilitiesWe analyze?the?differences between on-premise broadcast and cloud-based online video delivery workflows and identify?technologies?needed for bridging the gaps between them. Specifically, we note differences in ingest protocols, media formats, signal-processing chains, codec constraints, metadata, transport formats, delays, and means for implementing operations such as ad-splicing, redundancy and synchronization. To bridge the gaps, we suggest specific improvements in cloud ingest, signal processing, and transcoding stacks. Cloud playout is also identified as critically needed technology for convergence. Finally, based on all such considerations, we?offer sketches of several possible hybrid architectures, with different degrees of offloading of processing in cloud, that are likely to emerge in the future.

Translators for ATSC 3.0 - $15
Date: April 3, 2024Topics: 2024 BEITC Proceedings, Applications of ATSC 3.0 TechnologyThere are over 3000 TV translators presently licensed in the US. Translators, by definition, rebroadcast the signals of one or more originating stations on a different channel. As the ATSC 3.0 transition rolls on, these translator stations are faced with the need to retransmit the programs and advanced services that may be available from originating stations that have converted to 3.0. An ATSC 1.0 translator is comparatively a simple product – it typically consists of an 8-VSB receiver/demodulator, then an 8-VSB modulator/exciter, often with the ability to modify the PSIP information to be appropriate for the translator. An ATSC 3.0 translator brings a much higher level of complexity. Many of the functions of a broadcast gateway/scheduler must be included with the 3.0 translator, as it provides parameter information and baseband signal formatting for the exciter. While some translators use off-air RF input from an antenna, others use some terrestrial links (fiber, microwave, etc.) to deliver the program signals to the translator. These sources bring additional variations to the equipment required. Beyond that, a translator may choose to rebroadcast the program signals from multiple originating stations, so some multiplexing and signal grooming may be needed. Furthermore, a translator station may wish to continue to broadcast in the ATSC 1.0 format, while its originating station converts to ATSC 3.0, which creates other challenges. And there remains the issue of modifying the signaling information to be appropriate for the translator’s broadcast. This paper will examine these different operating situations and explain what is needed to afford the broadcaster the ability to take advantage of ATSC 3.0’s capabilities, while providing the required services to their viewers.

Transmitting Time and Frequency Data by Using Broadcast TV Signals Observed in Common-View - $15
Date: April 3, 2024Topics: 2024 BEITC Proceedings, BPS as the Complementary PNT SolutionWe will study the possibility of transmitting time and frequency data by using broadcast TV signals observed in common-view, in which two sites receive the transmissions from a single transmitter. The statistical characteristics of the path delay will make an important contribution to the error budget of the method, so that an evaluation of the path delay is an important first step in deciding whether to implement it. The variation in the path delay will be evaluated by receiving the signal at two sites and where the times of the clocks at both sites are known from other, independent methods. The advantages of the common-view method will be discussed; the method does not require any modifications to the transmitting equipment and is independent of the accuracy and stability of the transmitter time and frequency reference. In addition, the method cancels or attenuates the contribution of the path delay that is common to the paths to the two receiving stations that will participate in the test. The uncertainty in the coordinates of the transmitter and the receiving stations would be important in limiting the accuracy of a time service based on these transmissions, but the actual locations introduce only a constant bias into the delay and are not important for an evaluation of the stability of the method.
