Answer 1

$json = 'ваш json';
$array = json_decode($json);
$array = $array['channel_type']['1']['schedule'];

function comparator($one, $two)
{
    $one_time = strtotime($one['start']);
    $two_time = strtotime($two['start']);

    if($one_time == $two_time)
    {
        return 0;
    }

    return ($one_time < $two_time) ? -1 : 1;
}

uasort($array,  'comparator');
