Claims (15)

1. Способ передачи критичных ко времени данных через асинхронный канал, отличающийся тем, что включает следующие операции:
i) подразделение данных, критичных ко времени, в поток последовательных критичных ко времени единиц передачи,
ii) выделение из критичных ко времени данных по меньшей мере одной временной информации, посредством которой могут быть восстановлены данные, критичные ко времени;
iii) тегирование по меньшей мере некоторых единиц передачи с указанной по меньшей мере одной временной информцией,
iv) передача указанных единиц передачи вместе с тегами временной информации через асинхронный канал,
v) прием единиц передачи из канала вместе с тегами временной информации,
vi) восстановление из принятой информации критичных ко времени данных.1. A method of transmitting time-critical data through an asynchronous channel, characterized in that it includes the following operations:
i) subdivision of time-critical data into a stream of successive time-critical transmission units,
ii) extracting from the time-critical data at least one time information by which time-critical data can be recovered;
iii) tagging at least some transmission units with the specified at least one temporal information,
iv) transmitting said transmission units together with time information tags via an asynchronous channel,
v) receiving transmission units from the channel together with time information tags,
vi) recovery of time critical data from the received information. 2. Способ по п. 1, отличающийся тем, что данные, критичные ко времени, являются МРЕG потоком данных, а единицы передачи являются транспортными пакетами. 2.
