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.
Various arrangements for performing setup of a wireless network without pairing are provided. A request mapped to a first characteristic may be transmitted using a first wireless protocol. In response to the request mapped to the first characteristic, a listing of one or more wireless networks within range mapped to a second characteristic may be transmitted by a peripheral device. Using the first wireless communication protocol, a third characteristic mapped to the selected wireless network and the password may be transmitted to the peripheral device. 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.
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.

VOICE CONTROL FOR MEDIA CONTENT SEARCH AND SELECTION
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.
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.

Novel techniques are described for quick charging of batteries. For example, a battery charging system can include a battery charger integrated circuit (IC) and a fuel gauge IC coupled between a battery and a central processor to execute a stored multi-phase battery charging protocol. Executing the protocol can include charging the battery in a constant current regulation phase by applying a constant charge current until a charge voltage (e.g., measured by the battery charger IC) reaches a defined regulation voltage that is higher than the nominal voltage of the battery plus the voltage drop across series components of the battery. Protection of the battery during such charging includes monitoring a present relative state of charge (RSOC) of the battery (e.g., by the fuel gauge IC) to detect when the present RSOC reaches a defined regulation RSOC level that may be substantially 100 percent of the charge capacity of the battery.

TEMPORALLY-SEAMLESS CHANNEL CHANGE FUNCTIONALITY IN MULTICHANNEL STREAMING ENVIRONMENTS
Devices, systems, method, and program products are provided, which support temporally-seamless change functionalities during multichannel streaming sessions established between a streaming media server and a client media receiver. In embodiments, the method includes outputting, to a display device, a first streaming channel contained in a streaming channel bundle and assigned a high priority level. When receiving a channel change request to view a second streaming channel, the client media receiver monitors for additional channel change requests over a predetermined wait period. If an additional channel change request is received within the wait period, the client media receiver repeats the step of monitoring. Conversely, if an additional channel change request is not received with the wait period, the client media receiver sends a channel reprioritization command to the streaming media server to prioritize the second streaming channel over the first streaming channel in continued transmission of the streaming channel bundle.

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.
