摘要： The invention described herein improves and expedites compressed video data delivery by providing systems and methods for transcoding and pass through on a sub-picture level. For example, in MPEG embodiments described herein, transcoding and compressed video data pass through may occur on a macroblock or slice level. This permits portions of a picture that need no rate reduction to be passed through without transcoding. The invention may also implement pass through on a picture by picture basis. Accordingly, the invention may determine transcoding or pass through for each picture or picture subregion. Thus, systems and methods described herein provide flexible compressed video data transcoding and pass through, as determined by varying bit rate demands of compressed video data transmission.

摘要： According to the present invention, methods and apparatus for performing efficient inverse transform operations are provided. Zero patterns are identified in a block of transform coefficients to derive zero pattern information. Using the zero pattern information, inverse transform operations are performed on a subset of the columns of the block of transform coefficients. Zero patterns can optionally be identified in the resulting block. One-dimensional inverse transform operations are then performed on the rows of the resulting block to complete the inverse transform. In another example, one-dimensional inverse transform operations can be performed first on the rows and then on the columns.

摘要： A radio frequency (RF) device includes an RF transceiver, an RF antenna, and a magnetic signal detector. The RF is selected to be in the very high frequency (VHF), ultrahigh frequency (UHF), or super high frequency (SHF) bands such that the shielding effect is reduced and the RF device can be configured as a SIM card disposed inside a cellular phone with an increased RF communication range. The magnetic signal detector is used to sense a magnetic field signal from an RF reader, which includes an RF transceiver, an RF antenna, and a magnetic signal transmitter. The longer communication range afforded by the VHF, UHF, or SHF bands is reduced by the sensing of the magnetic field, thereby providing a communication range control, while the RF device and the RF reader exchange information through the RF channel with improved security as a result of the range control.
