A wearable form factor wireless camera may include an image sensor for capturing video, the image sensor powered by a battery internal to the wearable form factor wireless camera. The camera may be ruggedized and attached attach to clothing worn on a user. Further, the camera may include a burst transmission unit to transmit video via a cellular network, and include video analytics software executed by an internal processor, coupled to a buffering memory and powered by the battery. The camera may also include an internal storage device powered by the battery and configured to store video information at a first fidelity, the stored video information capable of being transmitted to a base station at the first fidelity and at a second fidelity. Also, the first fidelity may provide higher video quality than the second fidelity. The camera may switch the second fidelity to the first fidelity upon a trigger.

Communication quality adjusting system

A communication quality adjusting system includes: an environment information acquiring unit that acquires environment information representing an environment, in which a receiver is placed, and having an effect on a communication state of the receiver; a criterion determining unit that determines a criterion associating a communication state of the receiver and a reception form used when the receiver receives content in accordance with the environment information acquired by the environment information acquiring unit; and a distribution unit that performs control such that the receiver receives video content in the reception form corresponding to the communication state of the receiver on the basis of the criterion determined by the criterion determining unit.

Delivery of multimedia components according to user activity

Systems, methods, apparatuses, and computer readable media may be configured for establishing at least one session for delivery of multimedia. In an aspect, a first transmission of data fragments of a first component and a second transmission of data fragments of a second component may be transmitted and synchronized for presentation. If an inactivity event is detected the session may be maintained while reducing bandwidth consumption.

Real-time screen sharing

In implementations of the subject matter described herein, there are provided a method and apparatus for real time screen sharing. During the screen sharing of two devices, if a certain condition is satisfied for an image encoded by a first device and an image decoded by a second device, the first device pauses image processing images. If the pause time of pausing satisfies a certain length, a parameter associated with an image compression ratio is adjusted. After the first device resumes image processing, the adjusted parameter is used to encode a new image captured on the first device. According to implementations of the subject matter described herein, a transmission code rate during the screen sharing can be controlled according to the pause time of pausing image processing. The implementations of the subject matter described herein can reduce transmission latency of screen sharing, thereby effectively ensuring the user experience.

Systems and methods for bandwidth-limited video transport

Systems and methods for bandwidth-limited video transport are configured to receive (or otherwise discern) a selection of video parameter limits that correspond to a bandwidth limit and apply the video parameter limits to an input video stream to enforce the bandwidth limit while preserving video quality. Methods may include adjusting the video stream one parameter at a time until the adjusted video stream meets the bandwidth limit. Parameters to be adjusted may include image resolution, frame rate, image compression, color depth, bits per pixel, and/or color encoding. In some embodiments, the image resolution is reduced first, the frame rate is reduced next, and the image compression is increased last. The extent and/or order of the adjustments of the parameters may be selected by the user, based on the content of the video stream, and/or based on the bandwidth limit.
