System for handling variations in the reception of a speech signal consisting of packets

This system helps make internet phone calls sound smoother by dealing with choppy connections. It uses a special temporary storage area, called a jitter buffer, to hold incoming speech packets. A smart controller then dynamically adjusts the size of this storage based on the speech data, ensuring a continuous flow of sound. The claims specifically narrow this to systems using a CELP-type decoder.

Why it matters: Filed when internet telephony was nascent and processing power was limited. Today, ubiquitous high-speed internet and powerful mobile devices make sophisticated real-time speech processing, like dynamic jitter buffer management, much more accessible and performant on commodity hardware.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
