Video: Enhanced Redundancy of ST 2059-2 Time Transfer over ST 2022-7 Redundant Networks

We’re all starting to get the hang of the basics: that PTP is the new Black and Burst, that we still need sync to make studios work and that PTP (IEEE1588) is standardised under ST 2059 for use in the broadcast industry. So given its importance, how can we make it redundant?

Thomas Kernen from Mellanox and Chair within the STMPE standards community takes about his real-lift work on implementing PTP with an eye on redundancy methods

Thomas covers the following and more:

  • Whether 2022-7 works for PTP
  • BMCA Redundancy Model
  • Multiple Grand master use
  • Adjusting to dynamic variations in timing feeds
  • IEEE 1588 v2.1
  • Timing Differences in basic networks

Video: AV1 vs. HEVC: Perceptual Evaluation of Video Encoders

Zhou Wang explains how to compare HEVC & AVC with AV1 and shares his findings. Using various metrics such as VMAF, PSNR and SSIMPlus he explores the affects of resolution on bitrate savings and then turns his gaze to computation complexity.

This talk was given at the Mile High Video conference in Denver CO, 2018.

Video: The AV1 Video Codec

AV1 implementations are still being worked on along a number of fronts and the business cases are starting to shake out. Here’s a developer-focused look at AV1 from patents to the way it works and to lessons learnt implementing it.

It was last year that the Alliance for Open Media released its next-generation video codec AV1. It achieves better compression than proprietary competitors, while its patents can be licensed via a royalty-free, open-source friendly license. With a broad array of industry support including all major browser vendors, many hardware partners, internet streaming video and conferencing providers, many think this is the best chance yet to create a successful video codec of its type that achieves wide deployment.
