    Congress included $35 million in 2018 and $65 million in 2019 in the budget in support of this. In February 2019, VTR cleared Critical Decision 0, demonstrating a mission need requiring investment, the first in a series of project approvals. At that time, Secretary of Energy Rick Perry announced the start of the Versatile Test Reactor Project. [4]

    Verilog-to-Routing (VTR) is an open source CAD flow for FPGA devices. [1] [2] [3] VTR's main purpose is to map a given circuit described in Verilog, a hardware description language, on a given FPGA architecture for research and development purposes; the FPGA architecture targeted could be a novel architecture that a researcher wishes to explore, or it could be an existing commercial FPGA whose ...

    The PV-100 was Sony's second model of 2-inch helical VTR, and was released in September 1962. The PV-100 was solid state and had a total weight of about 132 pounds (60 kg). It found use in the airline industry as a replacement for 8mm and 16mm film stock, which were used for in-flight entertainment.

    A view-through rate (VTR), measures the number of post-impression response or viewthrough from display media impressions viewed during and following an online advertising campaign. Such post-exposure behavior can be expressed in site visits, on-site events, conversions occurring at one or more Websites or potentially offline:

  6. EIAJ-1 - Wikipedia

    When EIAJ-1 was standardized, no videocassette recorders had yet been introduced. One of the main drawbacks to the format was the need to carefully thread the end of the tape around the head drum, through a gap between the capstan and pinch roller, and around a variety of guides and tensioners.

    One 2/3" Vidicon video camera Akai produced two types of portable black and white VTR using 1/4 inch tape: Portables using an open reel of 13 cm diameter (VT-100/-110/-120), and a single stationary model using a 27 cm open reel, designated VT-700.

  8. Video tape recorder - Wikipedia

    en.wikipedia.org/wiki/Video_tape_recorder

    A video tape recorder (VTR) is a tape recorder designed to record and playback video and audio material from magnetic tape. The early VTRs were open-reel devices that record on individual reels of 2-inch-wide (5.08 cm) tape.

    Shortly after it came out, both the 1" Type B and 1" Type C formats of VTR came out. Both used less costly tape, and made just about as good of a picture. Ampex in 1961 made a 2 inch helical scan VTR for a short time, the VR-8000. They also produced another 2" helical VTR, the VR-660, in 1963.
