HDCAM deck HDCAM L tape. SMPTE 367M, also known as SMPTE D-11, is the SMPTE standard for HDCAM. The standard specifies compression of high-definition digital video. D11 source picture rates can be 24, 24/1.001, 25 or 30/1.001 frames per second progressive scan, or 50 or 60/1.001 fields per second interlaced; compression yields output bit rates ranging from 112 to 140 Mbit/s.
The basis for digital video cameras is metal–oxide–semiconductor (MOS) image sensors. [1] The first practical semiconductor image sensor was the charge-coupled device (CCD), invented in 1969 [2] by Willard S. Boyle, who won a Nobel Prize for his work in physics. [3]
a) The process of electronically processing a digital video picture to make it use less storage or to allow more video to be sent down a transmission channel. b) The process of removing picture data to decrease the size of a video image. c) The reduction in the volume of data from any given process so that more data can be stored in a smaller ...
The standard for consumer/prosumer HDTV acquisition is HDV (High Definition Video). It records MPEG-2 TS compressed HDTV video on standard DV media (regular DV or MiniDV cassette tape) and transfers it using FireWire. At this time all consumer/prosumer HD camcorders only record at a maximum resolution of 1440x1080.
Practical digital video cameras were also enabled by advances in video compression, due to the impractically high memory and bandwidth requirements of uncompressed video. [8] The most important compression algorithm in this regard is the discrete cosine transform (DCT), [ 8 ] [ 9 ] a lossy compression technique that was first proposed in 1972 ...
D-5 HD uses standard D-3/D-5 videocassettes to record HD material, using an intra-frame compression with a 4:1 ratio. It was introduced in 1994. [2] D-5 HD supports the 1080 and the 1035 interlaced line standards at both 60 Hz and 59.94 Hz field rates, all 720 progressive line standards and the 1080 progressive line standard at 24, 25 and 30 frame rates.

M-JPEG is an intraframe-only compression scheme (compared with the more computationally intensive technique of interframe prediction).Whereas modern interframe video formats, such as MPEG1, MPEG2 and H.264/MPEG-4 AVC, achieve real-world compression ratios of 1:50 or better, M-JPEG's lack of interframe prediction limits its efficiency to 1:20 or lower, depending on the tolerance to spatial ...
