I am now carrying out research about DTV and t-learning, but I am limited to experiments with the DTBM network. I read the attached work and I saw in table 1 the presence of the return channel, but I did not see DTBM in it.
Does DTBM have a return channel? I am new on these terms. Thanks for your time.
Article Challenges of Interactive Digital Television for t-Learning
Hi,
DVB-T which was primarily considered in the Enhanced Learning Unlimited project does in theory support return channel, but I newer really followed how this turned out to be in practice.
Please let me know what does DTBM stand for. Maybe I can give you a more precise answer than.
I hope this helps.
I am talking about the Chinese standard for DTV
