Cable television

Cable television is a system of delivering television programming to paying subscribers via radio frequency (RF) signals transmitted through coaxial cables or light pulses through fiber-optic cables. This contrasts with broadcast television, in which the television signal is transmitted over the air by radio waves and received by a television antenna attached to the television. FM radio programming, high-speed Internet, telephone service, and similar non-television services may also be provided through these cables.

A cable channel (sometimes known as a cable network) is a television network available via cable television. When available through satellite television, including direct broadcast satellite providers such as DirecTV, Dish Network and BSkyB, as well as via IPTV, it is referred to as a satellite channel. Alternative terms include non-broadcast channel or programming service, the latter being mainly used in legal contexts. Examples of cable/satellite channels/cable networks available in many countries are HBO, MTV, Cartoon Network, E!, Eurosport and CNN International.

Category 6 cable

Category 6 cable, commonly referred to as Cat 6, is a standardized twisted pair cable for Gigabit Ethernet and other network physical layers that is backward compatible with the Category 5/5e and Category 3 cable standards. Compared with Cat 5 and Cat 5e, Cat 6 features more stringent specifications for crosstalk and system noise. The cable standard provides performance of up to 250 MHz and is suitable for 10BASE-T, 100BASE-TX (Fast Ethernet), 1000BASE-T/1000BASE-TX (Gigabit Ethernet), and 10GBASE-T (10-Gigabit Ethernet).

Description

Whereas Category 6 cable has a reduced maximum length when used for 10GBASE-T, Category 6A cable (or Augmented Category 6) is characterized to 500 MHz and has improved alien crosstalk characteristics, allowing 10GBASE-T to be run for the same 100 meter distance as previous Ethernet variants.

Category 6 cable can be identified by the printing on the side of the cable sheath.

Cat 6 patch cables are normally terminated in 8P8C modular connectors. If Cat 6 rated patch cables, jacks and connectors are not used with Cat 6 wiring, overall performance is degraded and will not meet Cat 6 performance specifications.

Structured cabling

Structured cabling is building or campus telecommunications cabling infrastructure that consists of a number of standardized smaller elements (hence structured) called subsystems.

Subsystems

Structured cabling falls into six subsystems:

Station identification

Station identification (ident, network ID or channel ID) is the practice of radio or television stations or networks identifying themselves on-air, typically by means of a call sign or brand name (sometimes known, particularly in the United States, as a "sounder" or "stinger", more generally as a station or network ID). This may be to satisfy requirements of licensing authorities, a form of branding or a combination of both. As such, it is closely related to production logos used in television and cinema, alike.

Station identification used to be done regularly by an announcer at the halfway point during the presentation of a television program, or in between programs.

Asia

Idents are known as a montage in Thailand, and as an interlude in Cambodia and Vietnam.

Station IDs in the Philippines differ from the original concept. Instead of a way to identify television networks, these are presented in the form of music videos that represent the season in which the ident is aired during, which consist of tag-init (summer season), tag-ulan (rainy season), and Pasko (Christmas season). Station IDs in the Philippines runs for three to six minutes depending on the television station. The longest station ID is "Thank You Ang Babait Ninyo", which was used by ABS-CBN as a Christmas ID in 2014, lasting for ten minutes and 36 seconds. However, ABS-CBN, alongside some networks (i.e. UNTV, RPN, IBC, and PTV), also releases CGI-animated station IDs, not yearly but sporadically.
