Sony Corporation (Japanese katakana: ソニー) (NYSE: SNE) is a consumer electronics corporation based in Tokyo, Japan. It was founded by Masaru Ibuka and Akio Morita on May 7, 1946 as the Tokyo Telecommunications Engineering with about 20 employees. Their first consumer product, in the late 1940s, was a... Sony's D1 format was the first major professional Digital video is a type of video system that works by using a digital representation of the brightness and colour of each pixel of the image. Black and white digital video is also possible. Introduction Digital cameras come in two different image capture formats: interlaced and progressive scan. Interlaced cameras... digital video format, introduced in 1987 is a common year starting on Thursday of the Gregorian calendar. Events Environmental change Varroa destructor, an invasive parasite is found in the US October 15 - Hurricane force winds cause extensive damage in southern England. January January 1 - Frobisher Bay, Northwest Territories, changes its name to Iqaluit. In 1999... 1987.


D1 stored uncompressed digitized Component video is a type of video information that is transmitted or stored as two or more separate signals (as opposed to composite video, such as NTSC or PAL, which is a single signal). Most component video systems are variations of the red, green and blue signals that make up... component video, encoded at YUV 4:2:2 is a specific encoding for digital representation of the YUV color space. In YUV 4:2:2, the basic unit is composed of two pixels, and occupies four bytes of space. Each pixel has an individual 8 bit Y channel. Then, the first pixel specifies an... YUV 4:2:2 using the CCIR 601 is the old name of a standard published by the CCIR (now ITU-R) for encoding interlaced analogue video signals in digital form. The new name of the standard is ITU-R BT.601. It includes methods of encoding 525-line 60 Hz and 625-line 50 Hz... CCIR 601 raster format, along with Pulse-code modulation (PCM) is a modulation technique. It is a digital representation of an analog signal where the magnitude of the signal is sampled regularly at uniform intervals. Every sample is quantized to a series of symbols in a digital code, which is usually a binary code. PCM is... PCM audio tracks as well as Timecode is also the title of a 2000 film directed by Mike Figgis which was shot in one continuous take. A time code is a sequence of numeric codes generated at regular intervals by a timing system. Time codes are used extensively for synchronization. SMPTE time code family of timecodes... timecode on a 19mm (3/4") cassette tape. Uncompressed component video uses enormous bandwidth, and a simpler D2 is a professional digital video format, created as a lower-cost alternative to D1. The format still used no digital compression, but saved bandwidth and other costs by sampling a fully encoded NTSC or PAL composite video signal and storing that directly on to tape, rather than sampling component... D2 system soon followed.


D1 was notoriously expensive and the equipment required very large infrastructure changes in facilities which upgraded to this format. Early D1 operations were plagued with difficulties, though the format quickly stabilized and was renowned for its superlative image quality.


D1 is still in some usage as of 2003 is a common year starting on Wednesday of the Gregorian calendar, and also: The International Year of Freshwater The European Disability Year Events January January 1 - Luíz Inácio Lula Da Silva becomes the 37th President of Brazil. Pascal Couchepin becomes President of the Confederation in... 2003, and many of the technologies introduced with this format are still common to more recent digital videotape formats.


Panasonic is a brand used by Matsushita, a Japanese company, to market its products throughout the world. It was once parodied on The Simpsons as Panaphonics. Logo Ideas for life See also Panasonic Corporation of North America Categories: Stub ... Panasonic's D5 is an professional digital video format introduced by Panasonic in 1994. Like Sonys D1, it is an uncompressed digital component system, but uses the same half-inch tapes as Panasonics digital composite D3 format. HD D5 uses standard D5 video tape cassettes to record HD material, using... D5 format has similar specifications, but was introduced much later.

But now, like a shooting star, Sony has entered the fray with a compelling new pro field recorder that defies conventional expectations and seems destined to be a classic.
Its integrated stereo X-Y microphone configuration is nice, with Sony claiming the D1's condenser pair has a nearly 30 kHz frequency response and results in a sensitivity of nearly 6 dB superior to that of a standard outboard stereo microphone.
The good news is that Sony or a third party could build a one-piece battery cartridge that would pop in and out of the D1 in lieu of the AA battery tray.
