Short time distortion amplitudes are not generally quoted directly as a percent of the transition amplitude but rather are expressed in terms of an amplitude weighting system which yields “percent-SD.” This weighting is necessary because the amount of distortion depends not only on the distortion amplitude but also on the time the distortion occurs with respect to the transition. The equation for NTSC Systems is SD = at0.67 where “a” is the lobe amplitude and “t” is the time between transitions and distortions. In practice, screen graticules eliminate the need for calculations.
Refer to the figure below. Also see the discussion on Short Time Distortions.
Industry:Software
The data structure used to carry elementary stream data. It consists of a packet header followed by PES packet payload.
Industry:Software
The leading fields in a PES packet up to but not including the PES_packet_data_byte fields where the stream is not a padding stream. In the case of a padding stream, the PES packet header is defined as the leading fields in a PES packet up to but not including the padding_byte fields.
Industry:Software
A PES stream consists of PES packets, all of whose payloads consist of data from a single elementary stream, and all of which have the same stream_id.

Production system HDTV is the analogue of studio standard, HDTV, and addresses only a small part of what the SMPTE Committee on Hybrid Technology (H19) considers production, and in fact only a small part of what they consider electronic production. Thus, in the context of SMPTE 240M, Television Signal Parameters 1125/60 High- Definition Production System, production has a much more restrictive definition than that employed by CCIR, or the SMPTE Committee on Hybrid Technology (H19).To illustrate by example from SMPTE 240M, the scope explains, this standard defines the basic characteristics of the video signals associated with origination equipment operating at the 1125/60 highdefinition television production system. It is, therefore, directed to the equipment that first encodes the image information into this electronic format, for example, the studio camera and its associated electronics.
