摘要： Embodiments disclosed herein enable detection and improvement of the quality of the audio signal using a mobile device by determining the loss in the audio signal and enhancing audio by streaming the remainder portion of audio. Embodiments disclosed herein enable an improvement in the sound quality rendered by rendering devices by emitting an test audio signal from the source device, measuring the test audio signal using microphones, detecting variation in the frequency response, loudness and timing characteristics using impulse responses and correcting for them. Embodiments disclosed herein also compensate for the noise in the acoustic space by determining the reverberation and ambient noise levels and their frequency characteristics and changing the digital filters and volumes of the source signal to compensate for the varying noise levels.

摘要： Various methods and devices provide place shifting of a media stream to a remote device while also providing network functionality for a local area network (LAN) and/or a wide area network (WAN). The gateway includes a media interface for receiving audio/visual (A/V) signals from the media source, as well as interfaces to the LAN and/or the WAN. A media streaming module receives the A/V signals from the media interface and processes the received A/V signals to thereby create the media stream. A modem module receives the media stream from the media streaming module via a dedicated connection, network switch and/or other connection, and transmits the media stream to the remote device via at least one of the first and second network interfaces.

摘要： Disclosure is directed to managing more than one placeshifting transmission at a target device. The target device may be configured to receive a first video from a first placeshifting source and a second video from a second placeshifting source. The target device may additionally be configured to simultaneously output the first and second video on an output device, using various display screen configurations such as picture-in-picture, split screen, windows, and so. The first and second placeshifting sources may be content receivers having integrated placeshifting functions or may be content receivers provided in association with stand-alone placeshifting devices. A dual-tuner content receiver may also provide both the first and second placeshifting sources to the target device.

摘要： Disclosure is directed to managing placeshifting events that are scheduled to occur at specified times. In particular, embodiments are directed to automatically establishing a connection between a placeshifting server and a placeshifting client in order to facilitate a scheduled placeshifting event. The connection may be established by the placeshifting server, which is associated with a receiver, first connecting to a backend server to obtain connection credentials and then connecting to placeshifting client using the connection credentials. The placeshifting client, which is running on a target device, may be configured to register and update its connection credentials at the backend server as the target device moves between networks. The connection may also be established by the placeshifting client connecting to the server at time that the placeshifting client has determined the placeshifting event is to occur.
