Самый доступный способ квалификации, обслуживания и устранения неполадок IPTV сетей.
Основные возможности
- Автоматически тестирует все каналы и показывает результаты "прошел/не прошел".
- Полная эмуляция ресивера STB (Set Top Box).
- Показ видео с полноценным движением для всех анализируемых IPTV потоков.
- Одновременный анализ множества IPTV потоков.
- Точная оценка MOS (среднего субъективного мнения) для аудио и видео.
- Всеобъемлющая статистика для видео и транспортного потоков.
- Усовершенствованная система показателей восприятия качества видео.
- Работает в Windows XP/Vista/7.
