Which ITU standard specifies video coding at low bit rates?

When video must travel over networks with limited bandwidth, the ITU-T standard designed specifically for low bit rates is H.263. It was created to deliver usable video quality at restricted data rates by optimizing prediction, coding, and quantization for constrained environments, such as dial-up or congested networks. This focus on efficiency at low bitrates is what makes it the best fit for low bit-rate video coding. The other options pertain to different contexts—H.320 is about video telephony over ISDN, H.324 covers multimedia over PSTN, and HL-7 is a health data messaging standard—so they don’t specifically target low-bit-rate video coding.
