Term for the technique of sub-sampling each NTSC pixel into three sub-pixels used in the HD-NTSC ATV scheme.
Industry:Software
Colour information for a pixel packed into one word of memory data. For a system with few colors, this packed pixel may require only a part of one word of memory; for very elaborate systems, a packed pixel might be several words long. See Planar.
Industry:Software
Another name for 4FSC because the pixel clock is four times the frequency of the chroma burst. For (M) NTSC the pixel clock is 14.32 MHz (4 x 3.579545 MHz), and 17.73 MHz (4 x 4.43361875 MHz) in (B, D, G, H, I) PAL systems.
Industry:Software
To move the characters of a unit of information right or left. For a binary number, this is equivalent to multiplying or dividing by two for each shift.
Industry:Software
Allows the editor to manually control the capstan speed of the selected transport + and –10% using the joystick.
TSO is especially important when tape machines need to be exactly synchronised before finalising an edit. If audio monitors for all transports are left up, the edit point on the transport can be selected by listening for the audio echo and adjusting the transport speed until the machines are in exact synchronization.
Industry:Software
A unit of measure for complex audio signals, usually in dB. Zero VU is referenced to 1 milliwatt of power into a 600-ohm load.
The reference level of –20 dB in this programme is 0 VU.
Industry:Software
Software programmes that can instal into a main nonlinear editing software to give you additional features and/or specs.
Industry:Software
The time it takes a signal to make a transition from one state to another, usually measured between the 10% and 90% completion points on the transition. Faster rise times require more bandwidth in a transmission channel.
Industry:Software
Detail in a stationary image. Any amount of bandwidth is sufficient for the transmission of HDTV images with high static resolution, even a telephone line; the smaller the bandwidth, the longer it takes to transmit all of the resolution. Therefore, many ATV schemes with reduced bandwidths offer the static resolution of HDEP with limited dynamic resolution, resulting in motion artefacts such as motion surprise.
Industry:Software
A) Amounts of the three reference colour stimuli in a given trichromatic system required to match the colour of the stimulus considered.
Note: In the CIE standard colorimetric systems, the tristimulus values are represented by the symbols X, Y, Z and X~, Yn, Zn. b) The amounts of the three reference or matching stimuli required to give a match with the light considered in a given trichromatic system.
