  • Method for creating a system clock in a receiver device and corresponding receiver device
    Patent number: 7903774
    Abstract: According to a method for generating a system time clock in a receiving device for digital packetized elementary data streams (E), the packetized elementary data streams (E) being generated in a transmitting device by sampling at a sampling frequency (fsample) synchronized by a system time clock of the transmitting device, the sampling frequency (fsample) of one data stream is determined in the receiving device, and the program clock reference counter is synchronized with the data stream's sampling frequency.
    Type: Grant

  • Quantizing speech signal codewords to reduce memory requirements
    Patent number: 7269552
    Abstract: For the coding or decoding of speech signal sampled values, the values contained in the code books/code tables for the generation of the speech signal parameters are stored in quantized form. The processing can be carried out using processors with whole-number processing, without deterioration of the speech quality.
