A:Answer Hi Bill. The LG 24” HD Smart TV with webOS, Model # 24LQ520S-PU has a built-in ATSC Tuner that receives OTA (Over-the-Air) TV Broadcasts when you connect an indoor or outdoor antenna to the F-Type,75-Ohm, coaxial connector on the back of the TV labeled as 'Antenna/Cable In'.
All Over-the-Air TV broadcasts are supposed to include basic TV Guide data embedded within the broadcast stream that your antenna picks up. This is called Program and System Information Protocol (PSIP). PSIP data usually includes basic program title information but episode and season details are often missing and availability of this data for a specific channel rarely extends beyond 2-3 days in advance. Although it’s free, because PSIP data is so basic, sometimes unreliable, and abbreviated, it’s not terribly useful for applications like Over-the-Air DVRs that rely on more robust data to set recordings.
There are two major companies in North America – Gracenote (owned by Nielsen) and Rovi (owned by TiVo) – that offer TV Guide data aggregation and delivery as a paid service. These companies work directly with broadcasters and TV networks to gather and create enhanced TV Guide data that includes episode and series synopses, cover art, and metadata, like whether the episode is new or a rerun. The data is generally available two weeks in advance and is updated periodically as TV networks adjust their schedules. This rich guide data is then sold to cable companies, television and DVR manufacturers, and other entities...^Ivan
