Screenmedia zy-iv-if controller схема

When controlling a player, the controller MUST display a «Now Playing» button that changes its icon as appropriate for the type of media the player is playing. If the player is not playing any media, then this button is grayed out. May not work with all video output drivers. The advantage of this scheme is that the U and V signals are zero when the picture has no color content.

Designed to pair with drivers’ smartphones, Mirror Screen allows owners to access and control compatible apps on their phones through the car’s touchscreen. The colors in those systems are encoded with one of three color coding schemes: NTSC, PAL, or SECAM,[2] and then use RF modulation to modulate this signal onto a very high frequency (VHF) or ultra high frequency (UHF) carrier. Before transmission, the subcarrier itself, is removed from the active (visible) portion of the video, and moved, in the form of a burst, to the horizontal blanking portion, which is not directly visible on screen. (More about the burst below.) For NTSC, the subcarrier is a 3.58 MHz sine wave. Selecting a player results in: The player selection button highlights to show a remote player is selected.

Software such as video games and computer aided design (CAD) packages often allow vertical synchronization as an option, because it delays the image update until the vertical blanking interval. However, we have some workarounds that can tweak your FPS a bit. Most modern phones that are less than two years old will be able to sync with the Mirror Screen technology. During logon attempts, an Error 1030 appears on the endpoint.
