- n. physics The interaction of a photon with a medium in which it is converted into two photons of lower frequencies such that energy is conserved
Examples
“An ultra-violet laser passes through a downconversion crystal, where it produces two infrared photons Photons 2 and 3, which serve as the entangled pair for teleportation.”
“You see, the VIP 211 has no downconversion capability.”
“The new HD input on the TRACS recorder enables compliance recording or video logging without the need for an additional external device for downconversion.”
“The HD input on the TRACS recorder enables compliance recording or video logging without the need for an additional external device for downconversion.”
“HD to SD downconversion; LANC terminal is a good idea to include”
“LAKE SUCCESS, N.Y. - Canon introduced last week a new HD camcorder offering dual flash-memory storage sources and built-in HD-to-SD downconversion.”
“The unit offers video transcoding and upsampling as well as downconversion.”
“The main features are 64 independent downconversion channels, support for two 16-bit ADC inputs reaching 220M samples/sec, alias-free channel bandwidths as wide as 687.5 kHz, independent tuning of channels 'center frequencies with a resolution of less than 0.01 Hz, and a fractional resampler for setting output sample rates with a resolution of less than 0.01 Hz. You can reconfigure channels without affecting the operation of other channels.”
“Using the HD-SD downconversion allows you to convert an HD video clip to an SD clip in the camcorder itself, while the relay record setting lets you continue recording seamlessly from the internal memory onto a memory card if the internal memory fills up.”
“The HF R11 and HF R10 both feature an HD-SD downconversion setting, as well as a function called relay record.”
