The difference between cable TV, Internet or digital TV makes the picture on one TV tens of seconds faster than another.
Happy with the victory of U23 Vietnam, after the semi-final match on January 23, but Mr. Khoa (Tay Ho, Hanoi) was still annoyed because during the tense shootout, many times he Hearing the neighbors cheering and celebrating for a while, his TV came to the part where the Vietnamese player scored. Ms. Thanh Binh (Cau Giay, Hanoi) also faced a similar situation when watching the match live in the office. Even though watching from the same channel, one corner TV is faster than the other at the same time.
The fact that the same match live but have to watch the goal slower than the neighbor is a common occurrence for TV viewers, shared Dong, a longtime audiovisual player. The reason is that families are using multiple sources with different technologies, causing the playback time to be out of sync at the same time. For example, in Ms. Binh’s case, one TV watched via Internet TV service and the other TV used cable TV, even though they were watching the same channel.
TVs use different broadcasting technologies, so the picture is fast and slow.
Years ago, TV viewers mainly used analog TV received from outdoor antennas or cable TV, now, they can choose to watch from digital receivers, satellite TV, digital surface. land, even, watch online via Internet TV or websites on phones and computers.
Of the above signal transmission technologies, analog TV has the worst picture quality, but the signal is fastest, then to cable TV, because the signal is brought almost directly from the station to the TV, via less processing.
Digital television is a system that transmits and receives video and audio signals using digital signals, as opposed to the analog signals formerly used by traditional broadcasters. Television data is digitally compressed and requires decoding by a decoder specifically designed for the television, such as an HD cable player.
Internet TV , often has the greatest delay because the digital signal still has to go through the service provider to receive, convert to digital, broadcast to their server, then download and broadcast on devices. devices such as SmartTV, smartphone or computer…
Television over the Internet takes a lot of processing to transmit content to the TV.
According to Mr. Dong, in the same family and sharing a TV provider, it is still possible for a TV room to show a goal in front of the other room, even though they are watching the same channel and the first match. A TV that connects directly to the signal from the cable will give a few seconds faster results than a TV used through an HD cable receiver, because the signal does not have to go through an extra stage of processing and converting to digital.
According to experienced people, overcoming the delay of the picture on the TV is not possible, because this is related to the technology and services that the television system uses.
In some big cities such as Hanoi, Ho Chi Minh City or Da Nang, analog television has been discontinued and replaced by digital television. If you want to have beautiful picture quality, high resolution like HD, users are forced to use a receiver and decoder, which means that the picture is slower than a TV using only conventional cables.
Same TV channel, but watching on smartphones over the Internet can be much slower than watching on TV with cable TV.
However, to avoid having to celebrate the goal too late when watching the final match of the upcoming U23 Vietnam, viewers should use regular television sources instead of watching online. In turn, with Internet TV, thanks to its expanded features, users can easily review situations, goals or re-watch the match without having to wait for the channel’s broadcast schedule.
