Multimedia data transmission system
First Claim
Patent Images
1. A multimedia data transmission system for transmitting data between a sending side and a receiving side comprising:
- means for configuring transmission frames of 80×
L-bit lengths having the repetition frequency of 100 Hz uniformly collecting 80 basic time slots, specified without relation to the transmission rate, of L-bit lengths having repetition frequency of 8 kHz corresponding to the transmission rate 8×
L Kbps,means for configuring a multiframe by uniformly collecting 16 transmission frames without relation to the transmission rate,means for multiplexing a multimedia data, in every basic time slot, transmission frame or multiframe having a code transmission rate which is an integer multiple of 8 Kbps or matching said transmission frames or multiframe, andcommunication control means for notifying the receiving side by arranging and transmitting a synchronous code for identifying the partition of the transmission frames and the multiframes and bit assigning information indicating the bit assignment of multimedia data to a predetermined bit in the basic time slot.

Abstract
A vector quantizer which transmits the input vector of the time when the minimum distortion is larger than the preset distortion threshold value and stores such input vector into the second code book as the new quantizing representative vector for the use in the successive vector quantizing processes.
Further, since the first and second code book constitute in the form of tree-structure, calculation for search may be executed at a high speed.
