W3C MEIG monthly meeting: Performant TV applications

  • Past
  • Confirmed

Building a performant and polished UI for a TV application using HTML is extremely difficult. While devices have steadily increased their processing power, the CPU is heavily taxed by JavaScript and HTML rendering. Users expect a polished interface with gradients, drop shadows, animations and performance of a native app. However, the more complicated the UI the less time there is to use the main thread to do API / business logic work. In order to achieve 60fps, there is 16ms of processing time per frame and the browser will use most of that to do housekeeping work (see web.dev article on Rendering Performance). Even without any business logic, the UI is regularly janky and with business logic and API calls and lazy loading data, the performance of the UI is too poor to ship to customers.

This is a follow up to our previous discussion during TPAC 2021.

W3C MEIG and WNIG joint meeting: Multicast Receiver API

  • Past
  • Confirmed

The next Media & Entertainment Interest Group meeting will be on Tuesday 6th April. This will be a joint meeting with the Web & Networks Interest Group.

We'll be joined by Jake Holland from Akamai, to talk about the Multicast Receiver API (Chinese translation), which proposes a secure method for browsers to subscribe to one-to-many multicast streams - one of the motivating use cases being live video streaming at scale. The API builds on a number of protocols standardized or in development at the IETF:

  • Automatic Multicast Tunneling (AMT) (RFC 7450)
  • DNS Reverse IP Automatic Multicast Tunneling (AMT) Discovery (RFC 8777)
  • Discovery Of Restconf Metadata for Source-specific multicast (DORMS)
  • Circuit Breaker Assisted Congestion Control (CBACC)
  • Asymmetric Manifest-Based Integrity (AMBI)

We recommend that you watch Jake's previous presentation (video, slides) for background.
