480Mbit/sec transfer; Uncompressed, that's ~333333 pixels per frame for 60FPS. Not even considering overhead, but https://en.wikipedia.org/wiki/USB_video_device_class https://en.wikipedia.org/wiki/USB_video_device_class 1.1 support from 2005 includes Motion JPEG (low compression, all patents probably expired given it was developed in the 90s) and MPEG2 (also sufficiently old, to be unencumbered now).
However, if they'd use USB 3.0 ~ 5gbps, ideally over a USB-C port, the connection would be more modern, and easily able to handle even 4K video with now free from patents and well supported compression algorithms.

- mjevans 2y agoI like the new marketing names they finally settled on. https://en.wikipedia.org/wiki/USB#Connector_type_quick_reference https://en.wikipedia.org/wiki/USB#Connector_type_quick_refer... USB ${N}Gbps instead of the confusing old labels and operation mode classifications. I'll assume you meant the 5Gbps version of the link, which ( 5000000000/8/3/60 ) can drive about 3.47M (24 bit) pixels at 60fps, even raw. https://en.wikipedia.org/wiki/List_of_common_display_resolutions#Digital_standards https://en.wikipedia.org/wiki/List_of_common_display_resolut... It looks like 4K mode would require the use of VP8 (likely no hardware included) or h264. Patent license issues are soon to expire, (though some BS one won't until 2030, not sure how that's even possible), but no remedy for older models https://en.wikipedia.org/wiki/Advanced_Video_Coding#Licensing https://en.wikipedia.org/wiki/Advanced_Video_Coding#Licensin... drat.
