[mpeg-OTspec] Draft Call for Proposals for Color Font technology [1 Attachment]

[Levantovsky, Vladimir]

Hi Sairus,

Unicode emoji and creative titling isn't the only use case that were identified during numerous discussions we had both on public email lists and in private group discussions (in which you were also included as one of many recipients). The reality is, as one of your colleagues pointed out, is that the same fonts that are going to be used for display purposes will also need to be used e.g. for printing; even though the animation capabilities may not be applicable in printing applications or for document formats that are geared towards presentation of documents for distributed printing such as PDF, it does not and should not disqualify these applications from consideration by the OFF - there is nothing that would conceptually preclude color fonts including emoji and creative titling from being reproduced as part of the printed content (where printers' capabilities in general are always much more limited than other devices). Also, some display devices such as Digital TV set-top boxes have very limited processing / rendering power but can also run subtitling / messaging applications and implement other functionality where the use of color fonts could be a benefit.

In addition to emoji and titling, there have also been other use cases  identified, e.g. using color fonts to encode special purpose color symbols that are in wide use in many consumer electronic devices such as white goods and automotive applications. It is generally a good thing to make sure that a new functionality can be implemented on a wide variety of platforms and devices - something that has been traditionally considered a necessity for font rendering. Our intent is to make sure that the newly standardized technology does not discriminate against certain classes of devices and can be as widely supported as possible, hence the requirement for low implementation complexity - not all devices /platforms / applications are as capable and resource-consuming as e.g. web browsers are.

And, last but not least, I am a bit puzzled by the tone of your email. Isn't it a good thing in general to require that a future technical solution be rich in capabilities and low in implementation complexity? What makes you believe that low implementation complexity (requirement #4) is "called out" for? How is it different from requiring scalability (requirement #3) or rich design capabilities including support for color gradients and animation (requirement #2)?

Thank you,
Vlad

Hi, Vlad,

Could you please elaborate on why "low capability devices such as consumer appliances, DTV set-top boxes, car infotainment and navigation equipment, etc" are called out in Requirement 4?

Is it a general indication that OFF/OT needs to be able to work on all kinds of devices, or are there specific use cases for color/animated Unicode-encoded glyphs on these low-capability devices? For example, is there a need for Unicode-encoded emoji or creative titling/display, the main use cases discussed in these forums, on these devices?

Thanks,
Sairus
