Obviously, when the user operates the TV multiplex button to set
the TV state, the television display should be synchronized with

the VOD switch to select AV2, you can achieve the goal. (At this
time, press the TV switch button can also select AV1, then select
AV2, but the multiplex button is also set to TV select the state,
and vice versa).

have a lot of program input options, such as AV1 \ AV2 \ AV3 \ AV4
\ S-Video \ YUV \ RGB and so on, this time if you still let the
TV and VOD mode selection button and AV / TV switch, in the control
of VOD play Press the like key at the same time, if you want to
see if an I TV program started, you can press the TV select button
repeatedly to bring up the TV screen, and then watch the channel
by watching some of the programs. Some TV such as Haier has an Input
function key, press Input, the screen immediately shows all the
sources, by up and down the left and right keys to select, more
convenient, this TV's AV / TV function is still retained.
Sometimes you want to achieve the mode selection key without changing
the TV screen, do not let the AV / TV function interfere with TV
and VOD mode selection, you can set the code in the remote control
