Abstract: Method, device and computer program product for estimating quality of a video signal, wherein frames of the video signal are received at receiving means of the device, each frame comprising a plurality of blocks of pixels. A section of a first frame of the video signal, which is correctly received, is used to provide a concealed block for use in place of a block of a second frame of the video signal. A difference measure is determined indicative of a difference between at least some of the pixels surrounding the block in the second frame and the corresponding pixels surrounding the section in the first frame. The difference measure is used to estimate the quality of the second frame of the video signal.

Abstract: Disclosed is a communication system—for effecting communication events between a computer system, comprising first and second computer devices, and additional endpoint(s) connected via a communication network—comprising processing units, each having access to computer storage holding executable code modules for managing a communication event configured to implement a media modality controller configured to manage media modality of an established communication event and a call controller configured to establish the communication event. An instance of the media modality controller is assigned responsive to an instruction initiated to the media controller by the call controller to convey media modality control signals of the communication event to a media agent on the first device without accessing a call agent on the second device. The initiation of the instruction by the call controller is responsive to an instruction received via the network from the call agent on the second device.

Abstract: Disclosed herein is an instance of a media modality controller of a communication system which is assigned to convey media modality control signals of a communication event to respective media modality agents of endpoints of the communication event without accessing respective call agents of the endpoints. The media modality controller instance is so assigned independently of a call controller of the communication system and responsive to an instruction received via the network. The media modality controller instance is released from said assignment responsive to the media modality controller instance returning a response to the received instruction while the call controller continues to operate in communication with the call agents of the endpoints.

Abstract: Method, device and computer program product for stabilizing a video signal. A plurality of frames of the video signal are captured using a camera. A motion sensor associated with the camera is used to generate a plurality of samples representing motion of the camera. The samples are used to determine a displacement of the camera between a first time and a second time, wherein the first time corresponds to an exposure time midpoint of a first frame of the video signal and the second time corresponds to an exposure time midpoint of a second frame of the video signal. The determined displacement is used to compensate for motion in the video signal between the first and second frames caused by the motion of the camera, to thereby stabilize the video signal.

Abstract: Techniques for indication of wireless signal quality are described. According to various implementations, attributes of a wireless signal are detected and processed to ascertain a quality of the wireless signal. Based on an ascertained signal quality, indicia of the signal quality can be exposed. For instance, an indication of wireless signal quality is communicated to an application and/or service that manages communication of media data. According to one or more embodiments, an application/service may perform one or more actions based on the indication of signal quality, such as a procedure to improve signal quality, a procedure to optimize wireless performance, and so forth.

Abstract: Disclosed is a communication system for effecting communication events between endpoints connected via a communication network. The communication system comprises a plurality of processing units, each having access to computer storage holding executable code modules for managing a communication event. The code modules are configured to implement a media modality controller configured to manage media modality of an established communication event and a call controller configured to establish the communication event. The communication system further comprises a resource allocator configured to allocate physical resources of the processing units and computer storage to each of the call controller and the media modality controller. A grant of physical resources to the call controller is independent and different from a grant of physical resources to the media modality controller.
