I draw the reader’s attention to the fact that the title uses a definite and an indefinite article. Yes, because there is a big difference between _a_ Metaverse and _the_ Metaverse. _A_ Metaverse implies that there are many instances of the thing, _the_ Metaverse means that there is one instance. If I take the definition of metaverse provided by the recode article "Why you should care about Facebook’s big push into the metaverse", metaverse is “a virtual world where people…

Revisiting the “patents in standards” issue

Four years ago these days, I was writing a post on my blog titled A crisis, the causes and a solution. The subject was the issue of patents in MPEG standards.

Today video/audio conference is a virtual space where many of us spend their working hours. Still the experience of a conference suffer from many deficiencies depending on the fact that the way audio is captured and conveyed to the virtual space is inadequate. Our brains can separate the voice of competing speakers, and remove the effect of non-ideal acoustical properties of the physical space and/or the background noise in the same in the same physical environment. However, when the acoustic…
