  • Unravelling the Power of Single-Pass Look-Ahead in Modern Codecs for optimised transcoding deployment - $15

    Date: April 3, 2024
    Topics: ,

    Winner of the 2024 NAB BEIT Conference Proceedings Best Student Paper Award

    Modern video encoders have evolved into sophisticated pieces of software in which various coding tools interact with each other. In the past, single-pass encoding was not considered for Video-On-Demand (VOD) use-cases. In this work, we evaluate production-ready encoders for H.264 (x264), H.265 (HEVC), AV1 (SVT-AV1) along with direct comparisons to the latest AV1 encoder inside NVIDIA GPUs (40 series), and AWS Mediaconvert’s AV1 implementation. Our experimental results demonstrate single pass encoding inside modern encoder implementations can give us very good quality at reasonable compute cost. The results are presented as three different scenarios targeting High, Medium, Low complexity accounting quality-bitrate-compute load. Finally, a set of recommendations are presented for end-users to help decide which encoder/preset combination might be more suited to their use case.

  • Using a Private 5G Network to Support the International Broadcast of the Coronation of HM King Charles III  - $15

    Date: April 3, 2024
    Topics: ,

    Winner of the 2024 NAB BEIT Conference Proceedings Best Paper Award

    Wireless cameras for news contribution feeds regularly use “bonded-cellular” devices, which connect to and split the encoded video across multiple public mobile network SIMs. However, in high demand density environments with large crowds, the public networks can quickly become saturated and unable to sustain the necessary bitrates to support high-definition video. To overcome this and provide uncontested wireless connectivity, the largest pop-up 5G standalone non-public (private) network of its type was deployed outside Buckingham Palace and along The Mall to Admiralty Arch to support news contributions for domestic and foreign broadcasters at the Coronation of HM King Charles III, without changing the contribution workflow.

  • Video Processing on Quantum Computers  - $15

    Date: April 3, 2024
    Topics: ,

    Quantum computing is a multidisciplinary field comprising aspects of computer science, physics, and mathematics that utilizes quantum mechanics to solve complex problems faster than on classical computers. Quantum computers are available today on the cloud, although they are considered “Noisy Intermediate-Scale Quantum” (NISQ) computers with a small number of quantum bits (qubits) with limited performance due to short coherence time and noisy gates. However, quantum computers are improving all the time, and it is possible that in the future they could provide acceleration to video processing workflows. This presentation will give a short overview of quantum computing basics, some methods for representing images in qubits, and describe some of the research on potential video applications of quantum computing.
