Claims (6)

1. Способ уплотнения для мультимедийной связи в протоколе Н.223, содержащий этапы, согласно которым:
(а) кодируют мультимедийные данные; и
(б) уплотняют мультимедийные данные, кодированные на этапе (а) в блоках заранее определенного цикла, и в цикл вводят второй флаг, имеющий заранее определенную длину, с автокорреляцией, после первого флага, имеющего открытие и закрытие цикла.1. The sealing method for multimedia communication in the H.223 Protocol, comprising the steps according to which:
(a) encode multimedia data; and
(b) compressing the multimedia data encoded in step (a) in blocks of a predetermined cycle, and introducing into the cycle a second flag having a predetermined length, with autocorrelation, after the first flag having the opening and closing of the cycle. 2. Способ уплотнения по п.1, отличающийся тем, что указанный цикл также содержит заголовок с информацией данных; и полезную нагрузку с видео- и аудиоданными. 2. The compaction method according to claim 1, characterized in that said cycle also contains a header with data information; and payload with video and audio data. 3. Способ уплотнения по п.1, отличающийся тем, что второй флаг этапа (б) имеет разрядную структуру "10110010". 3. The sealing method according to claim 1, characterized in that the second flag of step (b) has a bit structure "10110010". 4. Способ уплотнения по п.1, отличающийся тем, что второй флаг этапа (б) является псевдослучайным кодом. 4. The sealing method according to claim 1, characterized in that the second flag of step (b) is a pseudo-random code. 5. Способ уплотнения по п.1, отличающийся тем, что уплотнение этапа (б) выполняют совместно с перемежением. 5. The sealing method according to claim 1, characterized in that the sealing of step (b) is performed in conjunction with interleaving. 6. Способ уплотнения по п.1, отличающийся тем, что второй флаг вводят в цикл, когда в цикле постоянно присутствует некоторое множество первых флагов, или когда в полезной нагрузке в нем не имеется. 6. The sealing method according to claim 1, characterized in that the second flag is introduced into the cycle when a certain number of first flags are constantly present in the cycle, or when it is not present in the payload.
