Video conferencing has been around since the 1990s, first based on ISDN for digital phonesystems, then H.323, and then SIP for the Internet. The underlying assumption was that phone calls and group communications would all rely on the same standards, creating a universal and seamless user experience. But even as COVID-19 made Zoom a generic term, these standards-based solutions never got much traction. Even for the popular applications, WebRTC seems to have made modest inroads. In this talk, I&#39;ll try to reflect on the reasons for this development, and why we other standards-based internet applications such as web browsers and email have been more successful. Video conferencing also shares this &quot;fate&quot; with text-based chat, where standards-based solutions are competing with WhatsApp, Slack and other proprietary platforms. I believe that transition from (room) hardware to downloadable software, control protocol complexity, industry structure and communication patterns are at least partial explanations for this development. Finally, I will speculate on how video interaction might evolve in the next few years.

Why is Zoom So Much More Popular than Standards-based Videoconferencing?

## Welcome to EMNLP 2024! 
We are excited to welcome you to one of the most prominent conferences in the field of Natural Language Processing. This year, EMNLP 2024 is being held in a hybrid format,
offering both virtual and in-person participation in beautiful Miami. Due to a record-breaking number of submissions, we've expanded the total number of accepted papers to accommodate more cutting-edge research from around the globe.

keynote

The purpose of SIGMAP 2021, the International Conference on Signal Processing and Multimedia Applications, is to bring together researchers, engineers and practitioners interested on information systems and applications, including theory and practice in various heterogeneous and interrelated fields including image, video and audio data processing, new sources of multimodal data (text, social, health, etc.) and Multimedia Applications related to representation, storage, authentication and communication of multimedia information. Multimedia is a research field that includes computing methods in which different modalities are integrated and combined, with the aim to take advantage from each data source. 
CONFERENCE AREAS 
1 . Multimedia Networking and Communication 
2 . Multimedia Signal Processing 
3 . Multimedia Systems and Applications 
4 . Multimedia and Deep Learning 
5 . Multimedia Indexing and Retrieval 
6 . Social Multimedia

What makes an image or a video more or less informative? Is there a way to generate an informative image or video? Unlike information theory which is based on the statistical properties of a data item, informativeness is a utilitarian concept. that deeply depends on the contextual information associated with visual objects. This presentation will explore the concept of informativeness for multimedia by adapting an idea from natural language processing. It will make the case that studying information substitutability may give us a clue of evaluating the relative informativeness of multimedia objects, and hence may provide an insight into the generation of synthetic multimedia items.
