    Abstract: Methods and apparatus are described for ultrasound transmission. A bit packet is created from received data. A cyclic redundancy check (CRC) is added to the bit packet based on the input data. The bit packet is encoded with forward error correction. The encoded bit packet is block interleaved to create a bit stream. The bit stream is converted into symbols. Each symbol is mapped to a dual tone multi frequency (DTMF). A first audio buffer based upon the DTMF is created. The audio buffer is provided for output.

    Abstract: Techniques for connecting using Miracast peer-to-peer communications are provided. Specifically, methods are presented, that when taken alone or together, provide a device or group of devices with an efficient way of streaming data from a source display onto the screen of a display device. The present disclosure includes a method that provides a more effective means for screencasting by using a pre-connect and stream mechanism.
