摘要:
A system and method for data communications involves receiving a data frame in a receiver using a sliding receive window protocol, where a sliding receive window of the sliding receive window protocol is identified by sliding receive window information, and determining whether the data frame is a retransmitted data frame using the sliding receive window information.

摘要:
The buffer management system (100) is arranged to control in a data communication system an end to end delay (Δ) of a data unit (150) from input to output. Blocks (104, 106) of data units (150, 152) are written in a buffer (102) with a block write rate (Rw), and data units (154, 156) are read from this buffer (102) with a read rate (Rr). The end to end delay (Δ) is controlled by adapting the read rate (Rr) from the buffer (102), and hence the buffer filling (F) on the basis of measurements of delays in the buffer management system (100). For the calculation of the read rate (Rr) at least an input time measurement (mTa) of an input time instant (Ta) of input of the data unit (150) in the buffer management system (100) is required
摘要:
A remote control extension system for controlling appliances (60,70,80). A remote control (20) is connected by means of a network (30) to an extender device (40). The remote control (20) transmits messages (110,120) to the extender (40) during the period, that a command (14) is to be It transmitted from the extender to an appliance. The command is for example a command having a variable duration, such as Volume UP. The extender (40) receives the messages. It transmits the command as long as it receives the messages from the remote control. It finishes the transmission of the command, if an expected message has not been received at a predetermined time. In this way, the duration of a command is limited in case of network disturbances.
