Broadcast Quality • Definedas a video stream, this level of quality states that the video stream is suitable for being included in normal TV broadcasting. • But we are not broadcasting our lectures on TV. Instead, we are streaming on online platform such as Microsoft Teams, Zoom Meeting, Google Meet, Cisco WebEx and Lifesize. • The term “broadcast quality” in this talk refers to crystal clear audio with no humming or feedback/echo, excellent video quality with no lagging even when streaming video on the platform, and ability to use add- on graphics and animation on the fly while teaching.

- 6. Stable Internet Connection 1. If forat home, apply for best line that you can afford. Mine is Unifi 500 Megabit/s at rm240/month. Maxis and Time is usually faster and cheaper. 2.That speed is only available to you with the correct gigabyte router and cables (Cat 5e or better). 3.Wi-Fi – go for dual band router, 2.4GHz (50 Megabit/s) and 5 Ghz (600 Megabits/s). 4.Sharing the internet line from your phone? You would be lucky to get 2 Megabits/s. Same speed like wi-fi HUKM? 5.Minimum internet speed for Zoom is 600 kilobit/s but 1.5 Megabit/s is preferred for group calls. 1080p need 3.0 Megabit/s. 6.Ping should be less than 150 ms. For LAN, it is usually between 5 and 20ms, for wi-fi close to 30ms and for handphone is much worse and can reach >100ms.

- 31. Conclusion You don’t haveto spend RM7600 to stream your webinar/lectures online. Instead, you can pull it off with a budget of EUR5 by doing what I did. Of course, the Finance Department won’t allow you to do that because public universities can’t buy stuff online, instead you must go through the local vendors. But at least I have proven that technology wise, it is feasible. I don’t want to comment on the other issues.
