Abstract: In an example, a method may include providing, via an application, a first video stream on a display panel of a user device. Further, the method may include receiving, from a user, a selection of an object of interest associated with a portion of the first video stream. In response to receiving the selection, the method may include providing additional visual information corresponding to the object of interest. Further, the method may include rendering a region of interest on the display panel using the additional visual information and the region of interest including the object. Upon rendering the region of interest, the method may include tracking movements of the object in the region of interest across video frames.

Abstract: A flexible and scalable software system architecture for implementing multimedia applications is disclosed. In one embodiment, the flexible and scalable software system architecture includes a platform abstraction layer (PAL), a device policy manager (DPM), a media engine, a library of commons (LoC) module, system management toolsets (SMT), one or more application services, an application control unit (ACU) and a user interface transaction layer (UITL). Further, the media engine is communicatively coupled between the PAL and the ACU, the LoC module is communicatively coupled to the ACU, the DPM, the media engine, the SMT, the PAL and the UITL, the DPM is communicatively coupled to the PAL, the ACU and the media engine, the ACU is coupled between media engine and the UITL, and the SMT is communicatively coupled to the ACU, the DPM, the media engine, the LoC module, the PAL and the UITL.

Abstract: A non-echo canceling voice band modem capable of detecting subscriber alerting signal (SAS) tones and customer premises equipment alerting signal (CAS) tones is provided. The modem includes a shaping filter, an analog-to-digital converter (ADC), a SAS tone detector, a CAS tone detector and an echo canceler. The shaping filter, which is located in a transmitting path of the modem, filters modem signals to be transmitted from the modem. The ADC, which is located in a receiving path of the modem, converts any incoming analog signal to corresponding digital signals to be used by the modem. The echo canceler, which is coupled to the SAS and CAS tone detectors, cancels any echoes in modem signals before sending said modem signals to the SAS and CAS tone detectors.
