HDCAM is a high-definition video digital recording videocassette version of Digital Betacam introduced in 1997 that uses an 8-bit discrete cosine transform (DCT) compressed 3:1:1 recording, in 1080i -compatible down-sampled resolution of 1440×1080, and adding 24p and 23.976 progressive segmented frame (PsF) modes to later models. The HDCAM codec uses rectangular pixels and as such the recorded 1440×1080 content is upsampled to 1920×1080 on playback. The recorded video bit rate is 144 Mbit/s. Audio is also similar, with four channels of AES3 20-bit, 48 kHz digital audio . Like Betacam, HDCAM tapes were produced in small and large cassette sizes; the small cassette uses the same form factor as the original Betamax . The main competitor to HDCAM was the DVCPRO HD format offered by Panasonic, which uses a similar compression scheme and bit rates ranging from 40 Mbit/s to 100 Mbit/s depending on frame rate.
60-743: HDCAM is standardized as SMPTE 367M , also known as SMPTE D-11 . Like most videotape formats, HDCAM is no longer in widespread use, having been superseded by memory cards, disk-based recording formats, and SSDs. Despite its decline in usage, Sony still manufactures new HDCAM tape stock as of 2023. 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. Each D11 source frame

The determinates of whether an NSB for a particular economy is a public or private sector body may include the historical and traditional roles that the private sector fills in public affairs in that economy or the development stage of that economy. A national standards body (NSB) generally refers to one standardization organization that
180-407: A company offers a product that is "compliant" with a standard. When an organization develops standards that may be used openly, it is common to have formal rules published regarding the process. This may include: Though it can be a tedious and lengthy process, formal standard setting is essential to developing new technologies. For example, since 1865, the telecommunications industry has depended on
240-504: A cyan lid. 440 Mbit/s mode is known as SQ , and 880 Mbit/s mode is known as HQ . Sony also announced a higher compression mode called SR Lite. As with the 440 and 880 mode, SR Lite utilizes the MPEG-4 Part 2 Simple Studio Profile but decreases the bit rate to 220 Mbit/s for 60i and 183 Mbit/s for 50i. SR Lite is locked at 4:2:2 color sampling but still maintains 10 bit pixel depth. It also allows for 50 and 60p at

Another area of interest is in defining how the behavior and performance of products is measured and described in data sheets. Overlapping or competing standards bodies tend to cooperate purposefully, by seeking to define boundaries between the scope of their work, and by operating in
600-1177: A proposal to form a new global standards body. In October 1946, ISA and UNSCC delegates from 25 countries met in London and agreed to join forces to create the new International Organization for Standardization ; the new organization officially began operations in February ;1947. Standards organizations can be classified by their role, position, and the extent of their influence on the local, national, regional, and global standardization arena. By geographic designation, there are international, regional, and national standards bodies (the latter often referred to as NSBs). By technology or industry designation, there are standards developing organizations (SDOs) and also standards setting organizations (SSOs) also known as consortia. Standards organizations may be governmental, quasi-governmental or non-governmental entities. Quasi- and non-governmental standards organizations are often non-profit organizations. Broadly, an international standards organization develops international standards (this does not necessarily restrict

To support the standard development process, ISO published Good Standardization Practices (GSP) and
780-513: A total data rate of approximately 600 Mbit/s. The increased bit rate (over HDCAM) allows HDCAM SR to capture much more of the full bandwidth of the HD-SDI signal (1920×1080). Some HDCAM SR VTRs can also use a 2× mode with an even higher video bit rate of 880 Mbit/s, allowing for a single 4:4:4 stream at a lower compression or two 4:2:2 video streams simultaneously. HDCAM SR uses MPEG-4 Part 2 Simple Studio Profile for compression, and expands
840-496: A university may have copies of technical standards on hand. Major libraries in large cities may also have access to many technical standards. Some users of standards mistakenly assume that all standards are in the public domain . This assumption is correct only for standards produced by the central governments whose publications are not amenable to copyright or to organizations that issue their standard under an open license. Any standards produced by non-governmental entities remain

A standards developing organization (SDO) is one of the thousands of industry- or sector-based standards organizations that develop and publish industry specific standards. Some economies feature only an NSB with no other SDOs. Large economies like the United States and Japan have several hundred SDOs, many of which are coordinated by the central NSBs of each country (ANSI and JISC in this case). In some cases, international industry-based SDOs such as
