摘要： Methods and devices for modified coding of blocks of residuals in the case of transform skipping. To better align the data with assumptions upon which the entropy coding scheme is based, the block of residual data is permuted at the encoder prior to entropy coding. The block of reconstructed data is then inverse permuted at the decoder to recover the reconstructed block of residuals. The permutation may include 180 rotation of the block, which may be of particular benefit in the case of intra-coded residuals.

摘要翻译： 在转换跳跃的情况下修改残差块编码的方法和装置。 为了使数据与熵编码方案所基于的假设更好地对齐，在熵编码之前，残留数据块在编码器处被置换。 然后，重构数据块在解码器处被逆置换以恢复重建的残差块。 排列可以包括块的180次旋转，这在帧内编码残差的情况下可能是特别有益的。

摘要： A method for parallel context modeling through reordering the bits of an input sequence to form groups of bits in accordance with a context model-specific reordering schedule. The reordering schedule is developed such that the groups of bits are formed to satisfy two conditions: first, that the context for each of the bits in a group of bits is different from the context of each of the other bits in that group, and the context of each of the bits in that group is determined independently from each of the other bits in that group. The parallel context modeling may be used in encoding or decoding operations.

摘要： A control circuit can extend presence information by including a service identifier element in the presence information, the service identifier element identifying a suite of services. Corresponding presence information that includes the service identifier element is transmitted to a watcher. By one approach the presence information further includes a version element defining a version of the suite of services. If desired, the presence information further includes a description element that is a human-readable string of characters that provides information about the suite of services.

摘要： A method, system and apparatus for obtaining enhanced location information for a mobile device. The mobile device is configured to allow a determination of its location, for example via GPS. Location data for the mobile device, exemplarily obtained via GPS, may be further specified using context information for the mobile device. Additional data is obtained and processed to obtain context information for the mobile device. Enhanced location information is determined for the mobile device at least in part based on processing the location data in association with the context information. Additional data may comprise, for example, ambient noise, speech, images or text.

摘要： Methods and systems for selecting input in a portable electronic device comprising a display and a plurality of input members are disclosed. The methods and system use semi-transparent windows displayed in partially overlapping layers to present output options to the user of the device. For example, the method includes detecting a pre-determined type of actuation of one of the input members of the electronic device and determining the representations associated with the actuated input member. The method further includes outputting the representations using the display, each representation appearing in a semi-transparent window, the semi-transparent windows being displayed in partially overlapping layers. The method further includes receiving a selection input and outputting the representation displayed in the top-most semi-transparent window using the display.
