Error resilient windows media audio coding

A unique sync mark is applied by an encoder to the beginning of each frame in a data packet of a Windows Media(TM) Audio bitstream by a Microsoft(R) Windows Media(TM) Audio (WMA) codec. The WMA decoder handles errors at the frame level for each data packet. When a frame in a data packet of a WMA file is corrupted, the decoder can continue to decode the next frame by searching for the next sync mark at the beginning of the next frame. Accordingly, error propagation is confined to a single frame and the decoder can simultaneously handle bit errors and packet erasures when decompressing a received audio bitstream.

Fast template-based tracking

Techniques to identify and track a pre-identified region-of-interest (ROI) through a temporal sequence of frames/images are described. In general, a down-sampled color gradient (edge map) of an arbitrary sized ROI from a prior frame may be used to generate a small template. This initial template may be used to identify a region of a new or current frame that may be overscan and used to create a current frame's edge map. By comparing the prior frame's template to the current frame's edge map, a cost value or image may be found and used to identify the current frame's ROI center. The size of the current frame's ROI may be found by varying the size of putative new ROIs and testing for their congruence with the prior frame's template. Subsequent ROI's for subsequent frames may be identified to, effectively, track an arbitrarily sized ROI through a sequence of video frames.

Combined Optical And Electronic Image Stabilization

Techniques to improve a digital image capture device's ability to stabilize a video stream are presented. According to some embodiments, improved stabilization of captured video frames is provided by intelligently harnessing the complementary effects of both optical image stabilization (OIS) and electronic image stabilization (EIS).

System and method for delivery of dynamically scalable audio/video content over a network

The present invention involves a new system and process for streaming delivery of dynamically scalable media content over a network, such as, for example, the Internet or a wireless network, while automatically accounting for both fluctuating network bandwidth and packet loss. A system of rate-distortion based packet selection and organization is used to maximize the quality of streamed media files that have been encoded using any conventional scalable encoder. Media file quality is maximized for available bandwidth by scoring packets comprising encoded media files based on their contribution to the quality of a reconstructed media file, then preferentially transmitting those packets having the highest scores. In addition, where packets are lost during transmission, those packets that will provide the maximum rate-distortion decrease, are preferentially retransmitted prior to other lost packets which, if transmitted in the same time slot, would provide a lesser rate-distortion decease.

Error resilient windows media audio coding

A unique sync mark is applied by an encoder to the beginning of each frame in a data packet of a Windows Media™ Audio bitstream by a Microsoft® Windows Media™ Audio (WMA) codec. The WMA decoder handles errors at the frame level for each data packet. When a frame in a data packet of a WMA file is corrupted, the decoder can continue to decode the next frame by searching for the next sync mark at the beginning of the next frame. Accordingly, error propagation is confined to a single frame and the decoder can simultaneously handle bit errors and packet erasures when decompressing a received audio bitstream.

Low-gain regenerative amplifier system

A regenerative amplifier system that is optimized for low-gain gain media is provided. The system is configured to include a minimum number of intra-cavity elements while still eliminating the leakage of the seed pulses from the output beam. In addition, the contrast ratio of the amplified pulses is increased even considering the long build-up time that is required in low-gain regenerative amplifiers. This is accomplished using a single Pockels cell between the oscillator and amplifier to select a single seed pulse for the cavity, instead of using a Faraday isolator. This directs the unwanted seed pulses in a separate direction from the output pulse. When the amplified pulse exits the cavity, it is directed in a direction away from the oscillator by the same Pockels cell. Only one additional Pockels cell and one polarizer are required inside the regenerative amplifier cavity.
