A camera tube in which a high-velocity electron beam scans a photo-emissive mosaic which has electrical storage capability.
Industry:Software
A linear pulse distribution amplifier will handle 4 Vp-p signals (pulses) but is limited to amplifying and fanning out the signal. Also see Regenerative Pulse DA.
Industry:Software
A hardware device that you use to communicate with windows and icons. You move the mouse to move the cursor on the screen, and you press its buttons to initiate operations.
Industry:Software
An international group of industry experts set up to standardise compressed moving pictures and audio. The first release of the MPEG standard was called MPEG-1.
Industry:Software
MPEG-2 expands the MPEG-1 standard to cover a wider range of applications.
Industry:Software
MPEG 3 was originally intended for HDTV applications but has since been incorporated into MPEG-2.
Industry:Software
The goal of MPEG-4 is to establish a universal and efficient coding for different forms of audio-visual data, called audio-visual objects. Coding tools for audio-visual objects are being developed to support various functionalities, such as object-based interactivity and scalability. The syntax of the audio-visual objects is being developed to allow for description of coded objects and to describe how they were coded. This information can then be down loaded into a decoder.
MPEG-4 is expected to be available by the year 2000.
Industry:Software
A standard for compressing moving pictures. MPEG uses the similarity between frames to create a sequence of I, B, and P frames. Only the I frame contains all the picture data. The B and P frames only contain information relating to changes since the last I frame. MPEG-1 uses a data rate of 1.2 Mbps, the speed of CD-ROM. MPEG-2 supports much higher quality with a data rate (also called bit rate) of from 1.2 to 15 Mbps. MPEG-2 is the format most favoured for video on demand, DVD, and is the format for transmitting digital television.
Industry:Software
Also referred to as Studio MPEG, Professional MPEG, and 442P@ML. Sony’s Betacam SX is based on MPEG 4:2:2.
Industry:Software
The ability to cut into an MPEG bitstream for switching and editing, regardless of frame types (I, B, P).
