Streaming is discussed. A method for wireless media streaming comprises receiving media data from a remote media source, transmitting the media data over a wireless connection to an electronic device, receiving data-link information, accessing the data-link information at an application layer, and determining at the application layer whether to change a transmission rate of the media data to the electronic device. The data-link information is received from the electronic device. The determination is based at least in part on the data-link information.

Adapting characteristics of a video stream. A source video stream is received comprising instructions to employ at least one reference frame at a video adaptation device, wherein the source video stream is encoded. The source video stream is adapted, at the video adaptation device, such that the instructions are adapted to store a different number of reference frames. A video stream is produced with the different number of the reference frames.
摘要:
A hybrid deinterlace mechanism employs motion detection as a precursor to select the value for each missing pixel of a deinterlaced frame. If the missing pixel is found to belong to a steady or non-motion portion of the image, then its value is replaced by the corresponding value in the adjacent field (i.e., merging is performed). Otherwise, (where image motion is present) spatial interpolation, preferably edge-adaptive interpolation, is employed to determine the value of the missing pixel.

Image display systems and methods are provided. A plurality of pixel groups, each including a plurality of independent pixels, forms a display. A plurality of lenses (1251-N) forming an optical array and aligned along at least one axis (130), can be disposed proximate the display. Each of the plurality of lenses can provide a limited viewing arc (1501-N) for each of the plurality of independent pixels. A sample system can also include a detector (160) to detect the presence and location of a first user (165) and a second user (170) and logic (175), that when executed by a processor (180) coupled to the display, routes a first display signal (1451) based upon the viewing arc of a first portion of pixels; and routes a second display signal (1452) based upon the viewing arc of a second portion of pixels.

Differential protection of a live scalable media is disclosed. A first scalable encoding method is utilized for encoding a layer of a live media bit-stream, the first scalable encoding method having a first error resilience and a first bit cost. In addition, a second scalable encoding method is utilized for encoding an enhancement layer of the live media bit-stream, the second scalable encoding method comprising a second error resilience lower than the first error resilience, the second scalable encoding method further comprising a second bit cost that is lower than the first bit cost.
摘要:
A process and apparatus for generating a deinterlaced digital output image from a plurality of sequential interlaced image fields processes selected ones (a pair of immediately successive fields of the same polarity) of the plurality of sequential interlaced image fields, so as to produce a global motion vector estimate of global translational motion between the selected image fields. An accuracy map representative of accuracy of motion compensation is then generated in accordance with the global motion vector estimate. An adaptive deinterlacer selectively deinterlaces one of the image fields in accordance with the accuracy map. The selectively deinterlaced image field is subjected to postprocessing in order to remove judder artifacts that may be present in the deinterlaced image field as a result of a misclassification of the global motion vector estimate as being accurate in one or more image regions of the deinterlaced image field.
