| Управление ролями и дополнительные медийные каналы для терминалов серии МСЭ-Т H.300
|
В Рекомендации МСЭ-Т H.239 определяются процедуры использования более одного видеоканала в системах на базе МСЭ-Т H.320 и присвоения отдельным каналам маркировки "роли", указывающей требования к обработке канала и роль содержимого канала в вызове. Ролевые маркировки применимы к системам сигнализации как МСЭ-Т H.320, так и МСЭ-Т H.245. Определенные процедуры охватывают управление, индикацию и механизмы обмена возможностями. Настоящая пересмотренная версия включает ряд исправлений опечаток и уточнений к предыдущей версии, в основном, в определении процедур MCU. |
