ASKARA – Television has long been the main media for Indonesian people.Almost every home must have a television as a medium of entertainment as well as a source of information.The Indonesian government through the Ministry of Communication and Information (Kominfo) plans to stop analog TV broadcasts and convert them to digital TV shows no later than 2 November 2022.The government through the Ministry of Communication and Information (Kominfo) has a work program that invites people to switch from Analog TV to Digital TV.Digital TV broadcasts have the advantages of clean images, clear sound, and equipped with advanced technology.Kominfo will also start the analog switch off or ASO stage this year, which is targeted for completion by November 2, 2022. The ASO program is part of the government's program to distribute broadcasting infrastructure development evenly.The Minister of Communication and Information (Menkominfo) Johnny G. Plate revealed that the phase 1 analogue TV broadcasting had already been stopped at 100 percent.Areas that are at this stage are declared ready to broadcast digital TV broadcasts."Analog Switch Off Phase 1, the percentage of multiplexing infrastructure readiness is 100% and ready to be implemented. Areas in Phase 2 and Phase 3 of ASO infrastructure development are targeted to be completed two months before their respective ASO period," said Johnny.In addition, Kominfo is also finalizing the mechanism for distributing free digital TV set top boxes to poor households.A total of 6.7 million free set top boxes will be distributed to make it easier for the public to enjoy digital TV broadcasts, even though the television sets are still analog.Many people think that the transition from analog TV to digital TV has to buy a new TV, so that old TVs such as tube TVs can no longer be used.In order not to misunderstand and at the same time dismiss this assumption, here is a review of the differences between analog and digital TV.Reporting from the Kominfo page, digital television broadcasts use digital signal modulation and compression systems that present images with sharper and cleaner quality.In addition, the sound is clearer and clearer, resembling the picture and sound quality of YouTube, Netflix, and the like.In broadcasting, digital TV only recognizes two statuses, receive (1) or not (0).If the broadcast receiving device can capture the digital signal, then the picture and sound can be enjoyed.While analog TV can be interpreted as TV that depends on the frequency of the signal emitted by the transmitter.The further away the antenna is from the transmitter location, the worse the captured image will be.This is due to the weak transmitter signal captured by the antenna.Not to mention the weather problems that also affect the capture of TV signals which have an impact on poor picture and sound quality.However, currently analog TV owners can still enjoy digital TV broadcasts without having to buy a new TV.People simply use a tool called a set top box (STB) which is installed on the old TV set.Set top box is a tool for capturing digital broadcasts so that they can be received by analog TV sets.Difference between Analog TV and Digital TVAnalog TV is a television technology that uses analog signals to transmit video and audio to the audience.Quoting DBPedia in analog television broadcasts, brightness, color and sound are set for the amplitude, phase and frequency of the analog signal.Analog TV is routed through a cable network.Quoting ImOn Insider, the difference between analog and digital TV is in terms of signal usage.Analog TV is an airwave that works much like a radio signal.Each station has a single frequency to broadcast analog television signals, the user must know that frequency as a channel number marker.Just like radio, analog television signals can suffer from frequency interference which causes color, brightness, and sound quality inconsistency.The further away from the source, analog television broadcasts will decrease which affects the quality of the impressions received by the audience.The difference between Analog TV and Digital TV is the signal emitted from the two broadcasts.Analog TV is limited to analog signals only.Meanwhile, digital TV can process digital and analog signals at once.Analog TV signals are similar to radio signals.Although both use digital technology, digital TV broadcasting is not the same as streaming TV via the internet or IPTV, subscription cable TV, and satellite TV (parabola).Digital TV broadcasting is not the same as subscription cable TV, satellite TV, streaming TV via internet devices or IPTV.When viewed in terms of image quality sharpness and sound clarity, digital TV can reach High Definition so that it is comparable to these types of broadcasts.Digital TV broadcasts can easily be obtained without signing up for a subscription with a broadcasting provider.Thus, digital TV does not require subscription fees like subscription TV (cable/satellite/IPTV).Not only that, digital TV is not the same as streaming TV, so there is no need for internet quota fees to cellular telecommunications providers such as streaming TV.When compared to satellite TV broadcasts (parabola), this broadcast also uses digital technology (DVBS/DVBS-2), and the installation and payment is similar with only one installation and one payment for a lifetime.But the difference lies in the type of receiving antenna that uses a satellite dish.Meanwhile, digital TV broadcasts use DVBT2 technology.Quoted from Instagram @siarandigitalindonesia, digital broadcasting is broadcasting that uses VHF / UHF radio frequencies as well as analog broadcasting.However, the signal is an MPEG-2 digital data conversion which can deliver cleaner and clearer audio visuals through a reception system known as Digital Video Broadcasting Terrestrial (DVB-T) which has now entered the second generation or DVB-T2.Digital Television is not streaming TV, so it doesn't require internet quota fees.Digital TV is not like satellite TV (parabola), digital TV broadcasts use DVB-T2 receiving antenna technology.Digital TV is not a subscription cable TV, so there is no need to pay a monthly fee.Kominfo will start migrating Digital TV.The digital television migration stage schedule will be carried out in five stages based on region and time.Quoting from broadcastdigital.kominfo.go.id, the definition of digital TV is television broadcasting that uses digital signals and a compression system so that the picture and sound quality is better.During the transition period, we can still watch analog television broadcasts, but it is highly recommended to immediately change the antenna signal to digital broadcasts.Digital TV is still free to air, aka free and can still be accessed by both analog TV and smart TV with the quality of picture sharpness and sound clarity of digital TV can reach High Definition.However, broadcasts on analog TV must be equipped with a broadcast receiver called a decoder / set top box (STB).And if the television at home already has available digital TV broadcast types, then there is no need to add STB and you can immediately catch digital broadcasts.What is STB and DVB-T2?A Set Top Box (STB) or dekorder is a device that functions to convert digital signals received from satellite, cable, or internet into analog format so that it can be displayed on an analog television screen.Set Top Box that is connected to an analog device, namely the Terrestrial DVB-T2 type.This STB does not require a special satellite dish to receive digital signals, it is enough to use a UHF-VHF television antenna.So just add STB on analogue tv, then people can enjoy digital broadcasts.Meanwhile, DVB-T2 is a type of digital signal that is read and decoded by a Set Top Box (STB) or DVB-T2 digital TV receiver.According to regulations, Indonesia uses DVB-T2 digital signals in broadcasting.Television broadcasting can be done via cable, satellite or the internet.The STB used is also different, such as, STB DVB-C (Cable), DVB-S (Satellite), DVB-IPTV (Internet Protocol TV).Meanwhile, in digital broadcasting, STB DVB-T2 is used.So make sure your Set Top Box has the DVB-T2 logo.And if you buy a Digital TV, make sure it is DVB-T2 certified.HOW TO Check TV Is Digital or NotQuoted by indonesiabaik.id, the Ministry of Communication and Informatics (Kominfo) will gradually stop analog television broadcasts (Analog Switch Off/ASO).For people whose television is still a television that only catches analog TV broadcasts, they are required to install a Set Top Box (STB) so that later they can receive digital TV broadcasts.To better understand digital TV, it never hurts to know the characteristics of digital television.Quoting from the broadcast page digital.kominfo.go.id, the following are the characteristics of digital TV that must be understood.The first characteristic is that it can be seen from its shape.Digital television is not tubular.The size is also not large and the weight is relatively light.Generally digital television has a slim and thin design.This television also uses liquid-crystal display (LCD) or light-emiiting diode (LED) screen technology.2. Has a Digital Broadcast Search (DTV) FeatureHowever, the thin screen does not guarantee that the television is included in the digital TV category.Because digital television must be equipped with features that support it.Digital television must have a digital broadcast search or DTV feature.Therefore, ordinary LED and LCD TV users need an additional DVB-T2 set top box (STB) to be able to watch digital TV broadcasts.Digital television is generally equipped with digital video broadcasting terrestrial second generation (DVB-T2) features.The technology is needed to receive digital signals and allows us to watch broadcasts without an external antenna.3. Image and Audio QualityThe next feature of digital TV is that it can be seen from the picture and audio quality.Digital television presents images with high definition (HD) resolutions up to 4k.Not only that, the sound produced is also better because it is equipped with surround sound technology including Dolby Audio.Is our TV already digital TV?The public can check easily by checking on the official page of the Kominfo Digital Broadcast.The method is:Go to the broadcast page digital.kominfo.go.id/Then select the "Digital TV Device" menuNext on the "Select Category" option select "Television"Next, enter the television brand and its model/typeIf the television brand and type are TVs that can receive analog TV broadcasts, the description of the brand and type will appearIf the television is not registered, a message will appear, "Sorry, the device you are looking for is not registered in our database or does not have a device certification".STB, became an important device to be able to enjoy digital broadcasts for analog TV users.When you want to buy an STB, choose an STB certified by the Ministry of Communication and Informatics.The STB certification by Kominfo is a form of guarantee that STB can definitely be used and its features can function optimally.To capture this digital TV broadcast, a special STB is needed that supports Digital Video Broadcasting - Second Generation Terrestrial, namely DVB-T2 STB, not other STBs such as DVB-C (cable) STB, DVB-S STB (satellite), and DVB-IPTV STB ( internet protocol tv)How to Attach STB to Analog TVHere are the steps to install STB on Analog TV to be able to enjoy digital broadcasts;1. Prepare TV, STB, TV Remote2. Connect the antenna cable to the STB3. Connect the RCA cable (red, yellow, white) to the STB4. Turn on the TV and STB remotely5. Select AV mode on analog TV6. Select the "Channel Search" menu, select "Auto Search"7. Select "Save", ready to watch digital TVMore information regarding Digital TV Migration/Analog Switch Off (ASO) can be viewed/downloaded at the link https://linktr.ee/migrationtvdigitalInformation about Digital TV Migration (Analog Switch Off) consists of: Read the Digital TV Migration (ASO) E-book;Read Digital TV Comics (ASO);Watch Digital TV Migration Short Movies;Digital TV Migration Video (ASO);Digital TV Migration News (ASO);How to Reach Digital TV in Your Area (Application).
