Most TV is still transmitted through the atmosphere by transmitter aerials on tall masts.
The most common mode of transmission of TV signals are digital satellite and cable. New technologies allow transmission of signals by digital terrestrial TV, using aerial broadcasts to a conventional antenna. This provides a greater number of channels and a better picture and sound quality.
One way communication Eg: TV,Radio
Data in a Simplex transmission is always one way. Simplex transmission are not often used because it is not possible to send back error or control signals to the transmit end. Simplex Transmission: Transmission in one direction only. Also referred to as half-duplex transmission
In radio we would have: Phone ( voice and music)- AM, FM, Citizens Band, SSB (Single side band)- then CW ( continuous wave) for code transmission, such things as Facsimile, Telex over radio ( Radio-teletype). which are entirely machine-generated like a typewriter keyboard, and so on... Television is a form of transmission mode- but is not radio but well, Video.

Data can be transferred in 3 different modes, these 3 modes are equally popular and used in common everyday situations. •Simplex If data can only be transferred in a single direction (one way) it is known as simplex. Television transmission is an example of Simplex transmission, here data can be transferred only to a television but no data can be transferred in the opposite direction. •Duplex When data maybe transferred in two directions simultaneously it is known as Duplex, a simple telephone conversation would be an example, while we usually don't talk simultaneously a telephone provides that 'duplex' functionality. •Half-Duplex In this mode of transmission as well, data maybe transmitted in both directions, however it cannot be done simultaneously. A Walkie Talkie would be an example of this mode of transmission. The different modes are implemented based on their requirements, for example in Simplex transmission, two way transmission is not required in television transmission thus Simplex is used.
mode service westpoint
Its transmission is direct.
Hotel mode
It is a special configuration mode that allows for servicing the TV. A technician may use the service mode to configure the TV to accept input from a new type of signal.
IR transmission type of transmission is used in television system .
Yes the TV does feature a sleep timer mode,that will turn off the TV after a set amount of time.
