摘要： A transmission method and apparatus for detecting the format of data when data is absent from the transmission packets. In situations where data to be transmitted via a predetermined network (e.g., IEEE 1394) is absent (i.e., missing, incomplete, intentionally blank, or not ready to be transmitted), the transmission method allows for the format of the absent data to be determined by the receiving side. According to this transmission method, the data transmission packets include a label section that indicates the format of the data or the absence of data. When the label section indicates an absence of data, a label group section is included in the data transmission packet to indicate the format of the data which is absent. This allows the receiving side to determine the format of the data that it should be receiving.

摘要： A CDMA communication system including a variable rate vocoder transmits voice data without restriction of an encoding rate of the vocoder and transmits a signaling message so that voice quality of the CDMA communication system can be improved. If the signaling message is an emergent signaling message to be transmitted within a certain time, the encoding rate of the vocoder is restricted to a half rate, a quarter rate, or an eighth rate. Thus, the signaling message can be transmitted with the voice data within the certain time, so that delay of the signaling message transmission can be prevented.
摘要翻译：包括可变速率声码器的CDMA通信系统在不限制声码器的编码率的情况下发送语音数据，并发送信令消息，从而可以提高CDMA通信系统的语音质量。如果信令消息是在一定时间内要发送的紧急信令消息，则声码器的编码率被限制为半速率，四分之一速率或八分之一速率。因此，可以在特定时间内用语音数据发送信令消息，从而可以防止信令消息传输的延迟。

摘要： A TDM data distribution system (10) includes a hub unit (12) with a multipoint transmitter (24) and any number of subscriber units (14), each of which has a multipoint receiver (28). A forward communication link (16) transmitted by the hub unit (12) exhibits a substantially constant baud and carrier frequency over a number of diverse modulation format (MF) time slots (42). However, the different MF slots (42) convey data using different modulation formats. Modulation order and coding rate may vary for different modulation formats. The multipoint transmitter (24) includes a number of encoding FEC processors (48), wherein each encoding FEC processor (48) is active only for selected ones of the different MF slots (42). When inactive, the internal states of the encoding FEC processors (48) are frozen. Each multipoint receiver (28) includes a decoding FEC processor (108) which is active only for MF slots (42) assigned to the same modulation format for which the decoding FEC processors (108) are programmed. When inactive, the internal states of the decoding FEC processors (108) are frozen.

摘要： A reassembly unit comprising of a reassembly buffer and a control unit and a detector. The reassembly unit monitors an amount of data AMD stored in the reassembly register and compares AMD to four thresholds, TS1, TS2, TS3 and TS4. TS1 and TS4 define the size of the reassembly buffer. TS2 defines the delay of reassembly unit 40. A difference between TS1 and TS2 defines an underflow recovery period in which data is not read out of the buffer. A difference between TS4 and TS3 define an overflow recovery period in which data is not written in the buffer. The four thresholds can be changed during an operation of the reassembly unit, allowing a user to adjust the thresholds according to the state of the reassembly unit.
