1.How non popular (FTA) LIVE Channels works which are not part of any BASE ott app like Akash Bangla, Rupasi Bangla.
The biggest advantage is that, non popular channels open directly. It still cannot compete with DTH but you can easily replace your DTH with this. The quality of SD channels is bit poor/ok or may be I am used to the YouTube way of watching live news. So I find hard to watch in SD. Popular channels like Sun, Star works via the app. Zee5 channels too. No sync issues like Firestick. I used to have a preview issue in Firestick with Sun NXT. I no longer have those here. The live tv ui is good but not great.
2. If I take set top box with plan 399 , will the box's live tv work if I am having my own hotstar, zee5, discovery ,sonyliv subscription ?
I doubt that. If your company provides BB bill claim, go for the 999 plan. Otherwise, the STB is useless. For the trial, I didn't get Amazon prime. Since I had all subscriptions already, I gave my wife's number for Jio to avoid conflict of Subscriptions. When I tried to use my Amazon prime account, it didn't work. I mean the sync between Jio Tv plus to Prime Video didn't happen. I have to watch it directly on the app. So i guess the same will be applicable for other apps too.
3. If i get subscription of 14 apps with my fiber connection will those subscription works on my mobile or Laptop ? Suppose i got hotstar subscription with fiber connection , can I use hotstar on my laptop using same subsciption or only limited to use on jio set top box.
There's a thread where it calls out how exactly each subscriptions in Jio fiber works. Do check that.
4. Basic difference between s fire tv stick and jio set top box ?
Ease of use and other things I have mentioned. You will miss Firestick too. You will no longer know about the lastest releases. Jio STB does not advertise or update about recent releases immediately and frequently. I have been seeing Radhe Shyam trailer until last week. The app list will be full of Jio apps. Firestick on the other hand, keeps the ads and promos up-to-date. It was perfect in that aspect.
Jio tv plus app has easily synchronised against all these 14 apps. You don't have to switch between apps to find movies.
Quality of Video and Audio - Video, i don't see a difference. Audio, there's clearly a difference. Not sure if it really delivers 5.1 for all apps. I don't usually bother too much about audio. As long as the voice is clear, i live with that
.
Thanks in advance.
Edit:
Finally, the trailer they play in the boot is quite annoying. It plays it self like DTH STB.
Star channels are advantage. But I never managed to watch it. It's too blurry. You can't get to see it.
