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. The method according to p. 1, characterized in that the time-critical data is an MPEG data stream, and the transmission units are transport packets. 3.

The method according to p. 6, characterized in that the two pointers indicate respectively the start and end times of the specified one transmission unit. 9. Способ по п. 8, отличающийся тем, что один указатель является байтовым положением в единице передачи. 9. The method according to p. 8, characterized in that one pointer is a byte position in the transmission unit. 10. Способ по п. 9, отличающийся тем, что данные, связанные с одним указателем, являются указателем момента времени некоторых из единиц передачи. 10. The method according to p. 9, characterized in that the data associated with one pointer is a pointer to the time point of some of the transmission units. 11. Способ по п. 10, отличающийся тем, что множество единиц передачи являются транспортными пакетами информационного сигнала в формате МРЕG. 11. The method according to p. 10, characterized in that the plurality of transmission units are transport packets of an information signal in MPEG format. 12. Способ по п. 11, отличающийся тем, что один указатель указывает на временной эталон программы (РСR). 12. The method according to p. 11, characterized in that one pointer indicates a temporary reference program (PCR). 13. Способ по п. 11, отличающийся тем, что количество единиц передачи равно 5. 13. The method according to p. 11, characterized in that the number of transmission units is 5. 14. Способ по п. 1, отличающийся тем, что данные, критичные ко времени, форматируются как блок данных, содержащий по порядку заголовок, тело блока, содержащее множество единиц передачи с указанной временной информацией, и блок проверки ошибок. 14. The method according to p. 1, characterized in that the time-critical data is formatted as a data block containing, in order, a header, a block body containing a plurality of transmission units with the specified time information, and an error checking block. 15. Способ по п. 12, отличающийся тем, что тело блока содержит множество единиц передачи и один теговый пакет, содержащий временную информацию для множества транспортных пакетов. 15. The method according to p. 12, characterized in that the body of the block contains many transmission units and one tag package containing temporary information for many transport packets.
