METHODS AND SYSTEMS FOR AUTOMATED MEDIA DEVICE COMMUNICATIONS CONFIGURATION
Methods and systems are provided for automatically establishing communications with a media device. One method involves a client device capturing and analyzing an image of a media device to obtain identification information associated with the media device, automatically configuring a network interface of the client device to communicate on a wireless network using at least a portion of the identification information associated with the media device obtained from the captured image, and thereafter establishing a peer-to-peer communication session with the media device via the wireless network. In one or more embodiments, a name or other identifier associated with the wireless network includes the portion of the identification information.

A connection to the selected wireless network using the password and the second wireless communication protocol may then be performed by the peripheral device.
Systems and processes are provided to detect a deeply discharged rechargeable battery. A process includes initiating a processor operative to perform a function within a battery-operated device, determining a first output voltage of a battery, charging the battery with a battery charger for a duration of time between three and seven seconds in response to the first output voltage being less than a cutoff voltage, rebooting the battery-operated device, determining a second output voltage of the battery, providing a user prompt indicative of battery fault in response to the second output voltage being less than the cutoff voltage, and shutting down the battery-operated device.
Various techniques are described herein for supporting voice command control of electronic programming guides (EPGs) and other media content selection systems. The voice input hardware and software components of a remote control device, television receiver, smartphone, virtual assistant, and/or other media device may receive voice commands from a user corresponding to a selection of a media content. In response to the received voice input, the media device may perform a speech-to-text conversion of the voice input, and then perform an analysis of the command text to determine one or more content selections of the user. The analysis may include identifying within the command text one or more television channel names, program names, or other media content names, as well as identifying other instructions, preferences, or other meaningful insights from the command text.
Media streaming to a phone, tablet or other mobile device is improved by adapting requests for content in anticipation of the device's future location. If a device is expected to pass through an area with poor wireless signal quality, then requests for media content can be pre-emptively obtained beforehand at places and times where the available bandwidth is more favorable. Further, requests for content may be delayed during lower bandwidth conditions if the device is expected to soon encounter more bandwidth. Content requests can be therefore optimized (or at least improved) based upon the expected bandwidth that will be encountered during the anticipated upcoming movement of the device.

Client and server devices identify each other over a LAN or similar network through a series of unicasts. Rather than broadcasting a service announcement or discovery request as a broadcast or multicast, for example, a device instead transmits a series of unicast messages using a finite set of recipient network addresses and port numbers. Responses to the unicast messages can be collected and tracked to thereby allow subsequent communications to occur via unicasts with only the recognized addresses, with a multicast to only the recognized addresses, and/or otherwise as desired. By allowing the clients and servers to communicate with a finite set of unicast messages, a "broadcast" type message can be sent on the network without a need for router configuration. Moreover, unicasts can be sent using different protocols (e.g., TCP) than the subsequent traffic (e.g., UDP), thereby making discovery of compatible devices on the network more reliable.
Systems, methods, and devices are provided for optimizing streaming bitrate during multiclient streaming sessions based, at least in part, on display profiles associated with client media receivers to which different video streams are concurrently provided.

A method of encoding packets of a media stream includes establishing a data connection between a client device and a server, sending a first packet of the media stream from the server to the client device at a first bit rate, receiving, at the server, a first acknowledgment signal from the client device responsive to receipt of the first packet, determining a second bit rate based on the first acknowledgment signal, and sending a second packet of the media stream from the server to the client at the second bit rate.
Systems, devices and automated processes reduce the effects of unwanted interruption during video encoding by reserving header space at the outset of video encoding. This reserved space can be progressively filled on any periodic or other basis as encoding continues so that a recent header is always available. If an interruption occurs, only the video content encoded after the last header write will be lost, thereby greatly reducing the effects of the interruption.

A player decodes and renders encoded digital data received from an encoder. During processing, the player periodically monitors dropped frames as well as time spent. If the dropped frames are below a minimum, the player determines to signal the encoder to increase bit rate or frame rate by consulting a table. If the player determines to increase bit rate, the player signals accordingly. However, if the player determines to increase frame rate, the player first verifies that the spent time is below a minimum. To the contrary, if the dropped frames are both above the minimum and a first maximum but not a second maximum, the player determines to signal the encoder to decrease bit rate or frame rate by consulting the table and signaling accordingly. However, if the dropped frames are above the second maximum, the player signals the encoder to decrease the frame rate without consulting the table.

FREQUENCY BAND SCALE FACTOR DETERMINATION IN AUDIO ENCODING BASED UPON FREQUENCY BAND SIGNAL ENERGY
A method of encoding a time-domain audio signal is presented. In the method, an electronic device receives the time-domain audio signal. The time-domain audio signal is transformed into a frequency-domain signal including a coefficient for each of a plurality of frequencies, which are grouped into frequency bands. For each frequency band, the energy of the band is determined, a scale factor for the band is determined based on the energy of the band, and the coefficients of the band are quantized based on the associated scale factor. The encoded audio signal is generated based on the quantized coefficients and the scale factors.
Systems and methods are described for aggregating and playing media content using a proxy server. A request is received, in the proxy server, to play media content from a placeshifting media source on a media player. The requested media content is received, in the proxy server, from the placeshifting media source. The proxy server determines the media playing capability of the media player, and transmits the requested media content to the media player in a manner that is compatible with the media player associated with the request.
Systems, methods, and program products are provided for selectively restricting the transmission of copy protected digital media content from a computer system, over a network, and to a remote display. In one embodiment, a method includes the steps of capturing digital media content rendered on the local display by a media player application executed by the computer system; determining whether the media player application is accessing copy protected digital media content; and, if the media player application is not accessing copy protected digital media content, converting the captured digital media content to a media stream and transmitting the media stream over a network for presentation on a remote display.

An adaptive gain control system and related operating method for digital audio samples is provided. The method is suitable for use with a digital media encoding system that transmits encoded media streams to a remotely-located presentation device such as a media player. The method begins by initializing the processing of a media stream. Then, the method adjusts the gain of a first set of digital audio samples in the media stream using a fast gain adaptation scheme, resulting in a first group of gain-adjusted digital audio samples having normalized volume during presentation. The method continues by adjusting the gain of a second set of digital audio samples in the media stream using a steady state gain adaptation scheme that is different than the fast gain adaptation scheme, resulting in a second group of gain-adjusted digital audio samples having normalized volume during presentation.

Systems and methods are described for providing a media stream transmitted from an encoding system to a remotely-located media player. The media stream is encoded according to an encoding parameter. Data is gathered about a transmit buffer within the encoding system, and the gathered data is processed to arrive at an estimate of network capacity and a calculated encoder rate. The encoding parameter is adjusted during subsequent encoding in response to a change in at least one of the esti-mate of network capacity and the calculated encoder rate.
