TEEB: Trans-European Stereoscopic 360-degree Event Broadcasting

At QoMEX 2024, a stereoscopic 360-degree hybrid conference experience was demonstrated. The camera itself was standing some few meters away from the test person, which meant that the latter could see her-/himself with a latency of one to two seconds. While ACR scores of overall, image quality, depth perception were positive and in line with each other, the latency-related DCR scores were more ambiguous. Corresponding statistics will be shown in this paper along with qualitative feedback from the test persons. The demonstration in 2025 takes the step to a more realistic use case where the stereoscopic 360-degree camera will be placed in Sweden, about 2200 km away from the QoMEX 2025 location in Madrid. Immediate quantitative and qualitative insights are expected to demonstrate the trade-off between image quality and delay perceptions that come with Trans-European Event Broadcasting (TEEB) over various networks.
