Systems and methods for quick start-up of playback in accordance with embodiments of the invention are disclosed. Media content may be encoded in a plurality of alternative streams and a quick start-up stream. The quick start-up stream may include media content that is encoded at a lower quality that the alternative streams and may be encrypted with a different, less secure encryption process than that of the alternative streams. During a start-up of playback, the playback device streams the media content from a quick start-up stream until a metric, such as a decryption key for the alternative streams is met. The device then streams the media content from the alternative streams in response to the metric being met.

One embodiment provides a technique for dynamically adjusting streaming media bit rates in response to user requests for accelerated playback. A user request to increase a playback speed at which the units of digital content are played back on a content player is received. Upon receiving the user request to increase the playback speed, while previously downloaded units of the digital content having a first bit rate are being output for display, and prior to downloading a next unit of digital content from a content server, embodiments determine that the increased playback speed cannot be maintained without buffer underrun if subsequent units of digital content are downloaded from the content server at the first bit rate. A second bit rate, lower than the first bit rate, is determined and the next unit of digital content is downloaded from the content server for playback at the second bit rate.

A technique allows delivering content in a videoconference among a plurality of conferees in multiple quality levels. Content distributed from a multipoint control unit that is connected to an endpoint that delivers the content to receiving endpoints may have two or more quality levels. The quality level can be adapted to the capabilities of the receiving endpoints and the current quality of the connection that is used to deliver the content toward the receiving endpoints. The quality level associated with an endpoint may change during a session dynamically, adapting the delivery mode to changes in the condition of the connection between the receiving endpoints and the multipoint control unit.

Systems, methods and program instructions are described for calling a database function with a URL. Many databases have functions, also referred to as logical elements, built into the database that can be called to retrieve data. A web URL can be used to call such a programming function by formatting the URL in a specific manner. A URL and dynamic values from the client are received. The URL can be parsed to determine the resource path and parameters, if any exist. The database function specified in the URL is called using the specified parameters, if any exist, and using the dynamic values from the client. The results can be streamed to the user.

Described are techniques for establishing communication between multiple devices. Responsive to a request received from a first device, connection data associated with one or more other devices may be accessed to determine whether the other devices may be accessed via a HTTP connection or a SIP connection. Parameters of the communication may also be determined from the request. Based on configuration data determined from the devices, communication data received from the first device may be transcoded for receipt by other devices, and data received from other devices may be transcoded for receipt by the first device. Web data unrelated to communications between devices may be passed to a web server.

Systems and methods are disclosed herein for media quality selection of media assets based on internet service provider data usage limits. One disclosed technique herein discusses receiving a data usage limit from an internet service provider. The data usage limit includes maximum data usage for particular user account data. A media asset is selected from a media streaming server that includes a plurality of qualities having respective data sizes (e.g., for video quality—4K, 1080p, etc.) A determination is made whether a selected data size from a selected quality of the plurality of qualities of the selected media asset exceeds remaining data of the received data usage limit. If so, a request is transmitted to the to the media streaming server to retrieve the selected media asset with a quality having a data size smaller than the respective data size.

An example computing device creates a resource module that acquires resource information relating to resources of the computing device and acquire quality of experience information corresponding to a quality of audio, and creates a roster module that displays a participant list including resource information relating to resources of a plurality of other computing devices connected to the teleconference and display quality of experience information corresponding to a quality of audio a user of each of the plurality of other computing devices experiences when connected to the teleconference. The device also creates a policy module configured to evaluate the resource information and quality of experience information acquired by the client resource module against rules of a teleconference policy and implement actions based on a determination that the computing device is non-compliant with one or more of the rules of the teleconference policy to control quality of audio during the teleconference.

In embodiments, apparatuses, methods, and storage media may be described for reducing the overhead associated with the transmission of channel training signals from an eNodeB (eNB) of a wireless network. Specifically, the eNB may receive feedback from a user equipment (UE) regarding the received signal energy of a first and second beamformed signal produced with a first and second beamforming vector, respectively. The eNB may identify, based on the feedback of the received signal energy, a signal subspace and a null subspace. The eNB may then transmit a channel training signal to the signal subspace.

Generally, this disclosure provides devices, systems and methods for provisioning of wireless local area network (WLAN) traffic load measurements to third generation partnership project 3GPP wireless cellular networks. A WLAN element manager (EM) may include a polling module to poll a WLAN access point (AP), the polling to request traffic load data from the WLAN AP; a timer module to trigger the polling module to poll at periodic intervals; a logging module to receive and log the requested traffic load data; and an integration reference point (IRP) agent including a reporting module to generate a traffic load report for transmission to a network manager (NM), the traffic load report based on the logged traffic load data.

A system and method of playing a video game in a streaming mode includes executing a selected video game on an assigned game server, receiving execution control signals corresponding to user inputs to a client device to generate multiple video frames. Encoding the video frames in a shared hardware compression. Some of the encoded video frames depend on a preceding frame. A first and a second encoded video frame are transmitted to the client device. A first feedback signal from a decoder in the client device identifies that the second encoded video frame was not received the decoder. A third encoded video frame dependency is adjusted to produce an adjusted third encoded video frame that depends from the first encoded video frame and the adjusted third encoded video frame is transmitted to the client device.
