Abstract
Official abstract text for this publication.
A buffer controller has a buffer for holding plural sets of data contained in a packet entered from a telecommunications network, a codec converter and a controller. When receiving a packet, the buffer controller has the controller put data, in the packet, in a storage position in the buffer corresponding to the sequence number of the packet, and makes a decision as to whether or not the codec conversion is to be performed. If packets are out of sequence, lost or dropped during communication, the buffer controller can correct the packet order and compensate the packet loss with the minimum delay.
First claim
Opening claim text (preview).
What we claim is: 1. A buffer controller, comprising: a buffer having a plurality of storage positions for storing a plurality of pieces of data that are each contained in a real-time protocol (RTP) packet having a sequence number and entered from a VoIP (Voice over Internet Protocol) telecommunications network; a codec converter configured to execute codec conversion on each piece of data delivered from said buffer; and a controller configured to put each of the plurality of…
