Tina Abrahamsson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Transmission over packet switched networks
    Patent number: 7009935
    Abstract: The invention relates to methods for encoding/decoding a digitized sound signal which is transmitted over a packet switched network in such a way that diversity is provided. Each sound segment of the digitized sound signal is encoded into at least two different segment descriptions, i.e. into different representations of the sound signal segment. The segment descriptions differ from each other in that they provide different quantization values for a digital sound signal sample. The different segment descriptions are transmitted in separate data packets over the network at different points of time.

  • Encoding and decoding of a digital signal
    Patent number: 6970479
    Abstract: The invention relates to methods for encoding/decoding of a digital signal which is transmitted over a packet switched network. Prediction samples are generated at the transmitting and receiving end. The digital signal is lossless encoded at the transmitting end, and lossless decoded at the receiving end, based on the quantizations of generated prediction samples. During encoding, the generated prediction samples are quantized separately from the quantization of the digital samples. The predictions are used in the index domain in the form of quantized indices during encoding/decoding of the digital signal.
