When I first watched the movie "Independence Day 2", I was quite impressed with such a scenario where the male and female protagonists at the lunar base and the earth talked to you through the big screen video.
In the world of science fiction, large-screen video calls between the earth and the moon are commonplace, and in real life, everyone is still accustomed to using their mobile phones for video calling. The largest screen in the family - the television screen has been idle for a long time.
Phone is still the preferred video call, but not perfect.
Pictures from the Internet
Due to the portability of the phone itself, the ease of touch-screen and the poor experience on the TV, I believe it is your first choice when you start a whim video call.
However, this has been holding a cell phone, your hands are not sour?
Video call with a mobile phone, experience the following deficiencies:
1. Hands held tired
2. shooting angle difference
3. A machine more difficult
4 small visual screen
The so-called 'ruler is short, ruler', these deficiencies can just make up for the TV:
- Liberate your hands and you can even dance to television
- Free to choose the camera shooting angle, easily fixed
- The phone is no longer occupied, you can chat while chatting, just to the net red restaurant location to book
- Big screen to facilitate more family and friends to participate and share
- More people, the location of the television camera can cover more people involved in the video
Big screen video calls have been tepid
Some vendors are also trying to promote video call applications on their own platforms, but the results are not satisfactory. The reason can often be summarized as follows:
1. The relationship is costly to build and the relationship chain is difficult to expand In order to connect the TA to your TV, you have to convince the TA to download another APP, register, activate, etc. on the smart device.
2. Call experience is poor: can not hear, look at the card.Audio and video calls = audio and video capture + processing + network transmission, these three pieces and contains many sub-items, any sub-items are in need of in-depth exploration;
3. Cross-platform features weak, cross-windows / Andrews / IOS platform video experience weak, uneven compatibility of different systems technology;
