  • Patent number: 7973818
    Abstract: There is provided a communication device for mixing effects data with real communication data. The communication device comprises a receiving element configured to receive real communication data, a first analog-to-digital converter (ADC) configured to convert real communication data to digitized real communication data, an effects data storage containing the effects data, a first mixer configured to mix the digitized real communication data with the effects data and generate first enhanced data, and a coder configured to packetize the first enhanced data to generate packetized data, and transmit the packetized data over a communication line. The communication device may be a phone, and the real communication data may be audio or video data, and the effects data maybe background effects audio or video data.

  • Patent number: 7782907
    Abstract: There is provided a DSL modem for integrating an analog voice band with DSL bands over a telephone line, where the analog voice band consists of 0-4 kHz frequency range, and the DSL bands consist of frequencies beyond 4 kHz. The DSL modem comprises a splitter configured to receive a telephone line signal from the telephone line and split the telephone line signal into an analog voice band signal and a DSL bands signal; a voice module configured to receive the analog voice band signal, digitize the analog voice band signal to generate digitized voice band signal and packetize digitized voice band signal into packetized voice band signal; a DSL module configured to receive the DSL bands signal and retrieve packetized DSL bands signal from DSL bands signal; and a multiplexer configured to multiplex packetized voice band signal and packetized DSL bands signal to generate multiplexed voice-DSL packets.
