DVB TV Problems

DVB or Digital Video Broadcasting is a standard for transmitting digital terrestrial television that is mainly European based. It is an industry led association of broadcasters, network operators, and software developers worldwide. They have contributed in the development and designing of a transmission standard for delivering digital television globally. Below are frequent asked questions on issues relating to DVB TV that has been answered by the Experts.

I responded to a pop-up window on my Panasonic TV that said new DVB information is available. I lost channels 3, 4 and 5 after selecting OK to run the system. Now it says that these channels are Invalid DVB channels. How do I restore them?

In order to restore the channels you have lost, you would first need to switch your TV off. Then you should disconnect the power cord for five minutes. This procedure would help in rebooting any new software downloaded by that pop up box. Once this is done, you would have to check if the channels are back. In case, this does not succeed to get your channels back, you would then need to load a new channel map by running a channel autoscan. However, if this procedure still does not work, you would need to check with the local transmitter on those channels and verify if they had sent you that information. It does not seem likely that Panasonic would send out any updates like this on your TV. You can get that kind of updates only from the TV stations. However, in a situation like this, the best thing would be to contact Panasonic directly, explain the situation and have them deal with this issue.

I have a Samsung UN46B8500 LED TV. Would it work on a DVB-T digital network in Australia and on an analog PAL system?

In this case, it is unlikely your Samsung UN46B8500 LED TV would function on a DVB or PAL signal. This is because the model of your television would support a NTSC/ATSC TV system. Moreover, it is not a multisystem TV and is a U.S. model. Therefore, neither a DVB nor a PAL broadcast would be a compatible transmission system in this case. While a conversion between the DVB and ATSC system seems unlikely, you would find converters that can convert a PAL signal into the U.S. NTSC signal. Alternately, you can also have your TV function properly, if you can connect a satellite receiver or cable box via HDMI input to your TV.

On my Panasonic TV, all my channels are digital except for BBC1. It is coming as invalid DVB channel. I have digital aerial and my area is both digital and analog. My TV doesn’t have any other problem. What should I do?

In this case, it seems likely that the DVB device in your TV set has become outdated. It would therefore fail to work with the changes made to the signal and the compression ratio of the signal. Apart from this model, there are many later models as well that are known to have this problem. Therefore, in a situation like this, the first thing that you should do is go for a full re-tune. You would not be able to reset the unit in this particular case, as there is no option available for factory reset within the service menu. But you would need to have a digital aerial for receiving the digital signals. According to the Digital UK Customer Service, it looks like your TV set is not included in their list of incompatible models. However, that list is incomplete. Hence there would be many more of these DVB TV sets, not compatible with the changes made to the digital transmission system within the last two years.

I have a Samsung LA46A950 TV. Can I run it on a DVB network in the Australian system?

Samsung LA46A950 TV should work well in Australia on a DVB network without any issues. It is a TV that is manufactured and designed especially to work in the Australian market. There is a DVB tuner installed within this TV and even the analog color system is compatible with the Australian transmission system.

DVB refers to the broadcasting standard used globally for digital television transmission. There is a list of these standards that include DVB-T (Terrestrial), DVB-C (Cable), DVB-S (Satellite), DVB-H (Handheld) and so on to name a few. There are about nine hundred million DVB receivers being used worldwide by services that operate on DVB standards. If you need clarification about your specific situation with respect to issues related to DVB TV, you may ask a TV Technician expert to evaluate your case details and provide a technical insight.
