BBC Programme Identifier
A BBC Programme Identifier (PID) is an alphanumeric, persistent, unique identifier for a television or radio programme brand, a season or series, or an individual episode, used by the BBC in their web URLs, iPlayer viewers, and internal databases. - this source erroneously expands the acronym as "Packet Identification number" All PIDs consist of a lower-case letter, followed by seven or more other characters which may be lower case letters, or digits. Vowels (a, e, i, o, u) are not used, so that offensive words cannot be generated inadvertently. The first letter "b" means the content reference identifier (CRID) authority is Red Bee; a "p" means that the authority is the BBC's Programme Information Pages database, (PIPs). An "s" is used internally, for PIDs identifying partners and suppliers. Other sources, denoted by different opening letters, could potentially be introduced. For example, the PID for the series ''The Life Scientific'' is b015sqc7 while the PID for the individual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Persistent Identifier
A persistent identifier (PI or PID) is a long-lasting reference to a document, file, web page, or other object. The term "persistent identifier" is usually used in the context of digital objects that are accessible over the Internet. Typically, such an identifier is not only persistent but actionable: you can plug it into a web browser and be taken to the identified source. Of course, the issue of persistent identification predates the Internet. Over centuries, writers and scholars developed standards for citation of paper-based documents so that readers could reliably and efficiently find a source that a writer mentioned in a footnote or bibliography. After the Internet started to become an important source of information in the 1990s, the issue of citation standards became important in the online world as well. Studies have shown that within a few years of being cited, a significant percentage of web addresses go "dead", a process often called link rot. Using a persistent identi ...

Unique Identifier
A unique identifier (UID) is an identifier that is guaranteed to be unique among all identifiers used for those objects and for a specific purpose. The concept was formalized early in the development of computer science and information systems. In general, it was associated with an atomic data type. In relational databases, certain attributes of an entity that serve as unique identifiers are called primary keys. In mathematics, set theory uses the concept of '' element indices'' as unique identifiers. Classification There are some main types of unique identifiers, each corresponding to a different generation strategy: # serial numbers, assigned incrementally or sequentially, by a central authority or accepted reference. # random numbers, selected from a number space much larger than the maximum (or expected) number of objects to be identified. Although not really unique, some identifiers of this type may be appropriate for identifying objects in many practical applications ...

BBC IPlayer
BBC iPlayer (stylised as iPLAYER or BBC iPLAYER) is a video on demand service from the BBC. The service is available on a wide range of devices, including mobile phones and tablets, personal computers and smart televisions. iPlayer services delivered to UK-based viewers feature no commercial advertising. The terms BBC iPlayer, iPlayer, and BBC Media Player refer to various methods of viewing or listening to the same content. Viewing or recording live television broadcasts from any UK broadcaster or viewing BBC TV catch-up or BBC TV on-demand programmes in the UK without a TV licence is a criminal offence. In 2015, the BBC reported that it was moving towards playing audio and video content via open HTML5 standards in web browsers rather than via Flash or its Media Player mobile app. On 17 October 2018, the BBC iPlayer Radio brand was replaced with BBC Sounds. In 2019, the BBC improved the format quality, taking the highest available on iPlayer to 1080p (full HD) from 720p (sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
