Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04N 7/12

US Classification:

3752401, 37524011, 37524019

Abstract:

A scalability type selection method and structure for hybrid SNR-temporal scalability that employs a decision mechanism capable of selecting between SNR and temporal scalability based upon desired criteria is disclosed. This method and structure utilizes models of the desired criteria such as the extent of motion between two encoded frames, the temporal distance between two encoded frames, the gain in visual quality achieved by using SNR scalability over temporal scalability, and the bandwidth available to the scaleable layer in deciding which form of scalability to use. Furthermore, the method and structure allows for control over the extent to which a certain type of scalability is used. By the selection of parameters used in the models, a certain type of scalability can be emphasized while another type of scalability can be given less preference. This invention not only allows the type of scalability to be selected but also to the degree to which the scalability will be used.

Abstract:

A multi-sensor system includes a first analog sensor sub-system, a second analog sensor sub-system, and a system for synchronizing the outputs of the first and second analog sub-systems. Each analog sensor sub-system includes a sensor that produces an analog output. Each sensor is coupled to analog circuitry that processes the output from the sensor. The system for synchronizing the outputs of the first and second analog sensor sub-systems simultaneously inserts a marker into the outputs of the first and second analog sensors. Then, the outputs of the analog circuitry of the first and second analog sub-systems are synchronized based upon the marker. The marker signal may be produced using a Barker sequence signal generator.

US Classification:

37524016, 382236

Abstract:

Method and apparatus for selecting a reference frame for motion estimation in a video encoder is described. In one example, motion estimation is performed on a current macroblock in a current frame with respect to a reference frame to obtain a motion vector, a sum of absolute difference (SAD), a global motion vector, and an average SAD. A first relative change of the motion vector with respect to the global motion vector is computed. A second relative change of the SAD with respect to the average SAD is computed. A functional based on the first relative change, the second relative change, a first parameter, and a second parameter is computed. The functional is compared with a threshold. The reference frame is selected if the functional satisfies the threshold.

Abstract:

A first video signal processor () receives a first encoded video signal from which a video unit () generates a second encoded video signal, where the second encoded video signal is a reduced data rate version of the first encoded video signal. An error encoder () generates error redundancy data for the second encoded video signal and a multiplexer () generates output video data comprising the first encoded video signal and the error correcting data but not comprising the second encoded video signal. A second video processor () receives the output video data and a video unit () regenerates the second video signal from the first video signal. An error unit () detects errors for at least a first segment of the second video signal in response to the error redundancy data. A combiner () then generates combined video data by combining corresponding segments of the first encoded video signal and the second encoded video signal.

A method is provided for maximizing utility of a media delivery network having a media source, a first media adaptor, a second media adaptor and a media renderer. The media source can provide data in a first format and a second format. The first media adaptor can receive the data in the first format from the media source. The second media adaptor can receive the data in the second format from the media source. The first media adaptor can further provide data in a third format based on the received data in the first format. The second media adaptor can further provide data in a fourth format based on the received data in the second format. The media renderer can render the data in the third format and can render the data in the fourth format. The method includes: defining constraints of the media delivery network; predetermining factors to measure a utility of the media delivery network; defining a utility function based on the predetermined factors; and maximizing the utility function in light of the defined constraints.

US Classification:

375240, 37524021, 37524025

Abstract:

A scalable video compression system () having an encoder (), bit extractor (), and decoder () for efficiently encoding and decoding a scalable embedded bitstream () at different video resolution, framerate, and video quality levels is provided. Bits can be extracted in order of refinement layer (), followed by temporal level (), followed by spatial layer (), wherein each bit extracted provides an incremental improvement in video decoding quality. Bit extraction can be truncated at a position in the embedded bitstream corresponding to a maximum refinement layer, a maximum temporal level, and a maximum spatial layer. For a given refinement layer, bits are extracted from all spatial layers in a lower temporal level prior to extracting bits from spatial layers in a higher temporal level for prioritizing coding gain to increase video decoding quality, and prior to moving to a next refinement layer.

Abstract:

A method and apparatus for encoding and decoding video performs transformation of at least a portion of a high-resolution video frame into a low resolution image and a plurality of enhancement data sets, encodes the low resolution image as a primary coded picture in a bitstream format and encodes each of the plurality of enhancement data sets as a different redundant coded picture in the bitstream format. For decoding, a decoded low resolution image and a plurality of decoded enhancement data sets are generated and an inverse transform is performed to construct a decoded high-resolution image. The primary coded picture and a redundant coded picture may be formatted according to the ITU-T H. 264 Advanced Coding specification. The transform may be a polyphase or a sub-band transform.
