Go through the 4 pages and see what you can find here. I saw one unit here with dual display (but not too clear for me as the dual display mean here).
My family is used to a tv which has two feeds from std cable to two independent tuners and from two analogue video sources (currently hooked up to two recorders - each with their own tuners and are capable of recording one tv channel and passing through to the video out either that channel, or a playback of a tv recording, either completed previously or chaseplay on the current simultaneous recording. The TV has the full picture and can insert a smaller PiP (Picture in Picture) into a corner. The source for the main screen can be sourced from either of the two internal tuners, or from either one of the the two analogue feeds from the recorders. The PiP image can also be sourced from any one of the four available sources.
The combinations and permutations are substantial. We like to be able to have a feed to the larger image on the main tv and simultaneously have a feed to the PiP. One tv we had enabled us to switch the audio so we could listen to the audio from the PiP whilst watching the video on the larger image. Also, a feature we currently use extensively, is switching the PiP and the main image. Whilst the twoimages are on the screen they can be fully controlled as to channel (if using a local tuner), the signal source etc. The PiP can also be turned off leaving the main image on the screen.
With the advent of the large screen tv's this feature has not been replicated. The manufacturer's current definition of PiP (when apparently implimented) is only available if one of the feeds is through the local sole tuner and the other feed is from any other video source. Besides PiP is also considered to be the two feeds occupying half the screen each.
I would like to know if there is anyway the above analogue system we like can be done on the large screen tvs? I feel that this should be possible with software. It may be necessary to take a computer, install multiple tuners as well as have the ability to input two or more audio/video sources, use software to create a display which emulates the PiP and that image is then fed to he big screen tv preferably using a digital interface.
The tvs have been with 4:3 aspect ratios. The big screens are 16:9 which provides an opportunity to have three (or more) PiPs displayed without compromising the main image real estate too badly - it might mean there may be a black bar at top/bottom if that ratio is maintained.
Does anyone know if my objective is feasible, whether it has been done before, how it can be done, what hardware specs are necessary, what OS can handle this task, the software and if the end result is affordable?
Since we have access to digital cable does anyone know if there is a practical way in which the digital signals can be managed so that the use of a set top box can be avoided?
