摘要： An apparatus and method for detecting and analyzing spikes in network jitter and the estimation of a jitter buffer target size is disclosed. Detected spikes may be classified as jump spikes or slope spikes, and a clipped size of detected spikes may be used in the estimation of the jitter buffer target. Network characteristics and conditions may also be used in the estimation of the jitter buffer target size. Samples may be modified during playback adaptation to improve audio quality and maintain low delay of a receive chain.

摘要： A method for refreshing blocked media packets for a streaming media session over a wireless network in a stall condition is disclosed. The method can include a wireless communication device maintaining a buffer at an application layer. The buffer can contain at least a portion of media packets provided to a baseband layer by the application layer for transmission. Media packets provided to the baseband layer can be queued in a baseband queue prior to transmission. The method can further include the wireless communication device generating at least one new media packet for the streaming media session during the stall condition; flushing at least a portion of the media packets queued in the baseband queue; and replenishing the baseband queue by providing the baseband layer with at least a portion of the media packets contained in the buffer and at least one new media packet.

摘要： In video conferencing over a radio network, the radio equipment is a major power consumer especially in cellular networks such as LTE. In order to reduce the radio power consumption in video conferencing, it is important to introduce an enough radio inactive time. Several types of data buffering and bundling can be employed within a reasonable range of latency that doesn't significantly disrupt the real-time nature of video conferencing. In addition, the data transmission can be synchronized to the data reception in a controlled manner, which can result in an even longer radio inactive time and thus take advantage of radio power saving modes such as LTE C-DRX.

摘要： Some embodiments relate to a device that transmits/receives encrypted communications with another device. A first device, such as a smart phone or smart watch, may generate a message associated with a certain data class, which may determine the security procedure used in the communication of the message. The first device may establish an encryption session for the purpose of communicating the message to a second device. Prior to sending the message, the first device may wait until encryption credentials are accessible according to certain conditions, which may be determined at least in part by the data class of the message. Similarly, after receiving the message, the second device may not be able to decrypt the message until encryption credentials are accessible according to certain conditions, which may be determined at least in part by the message data class.

摘要： A video streaming method for transitioning between multiple sequences of coded video data may include receiving and decoding transmission units from a first sequence of coded video data. In response to a request to transition to a second sequence of coded video data, the method may determine whether a time to transition to the second sequence of coded video data can be reduced by transitioning to the second sequence of coded video data via an intermediate sequence of coded video data. If the time can be reduced, the method may include receiving at least one transmission unit from an intermediate sequence of coded video data that corresponds to the request to transition, decoding the transmission unit from the intermediate sequence, and transitioning from the first sequence to the second sequence via the decoded transmission unit from the intermediate sequence.

摘要： Methods, systems, and apparatuses are provided for managing communication of data to/from a device. For example, multiple client applications running on the device can communicate to a second device through a same primary socket connection. A mux module can receive data from two different client applications over respective client connections. The received data can include header information identifying the second device as the destination. When the first data from a first client application is received at the mux module, the primary socket connection can be created; and when the second data from a second client application is received, the existing primary socket connection can be identified and re-used. The primary socket connection can be managed by a controller of the mux module.
