摘要： Creation of a Bit-accurate film grain pattern for blending in an image block occurs by first establishing a set of bit-accurate transformed coefficients. The set of bit-accurate transformed coefficients undergo frequency filtering and a subsequent bit-accurate inverse transformation to yield the film grain pattern. The film grain pattern can then undergo blending with an image block to restore the look of film to the image.

摘要： Reduction in the blockiness of a simulated film grain block can be achieved either by the use of adaptive downscaling or adaptive deblocking filtering to adjust the intensity of the pixels at the block edge in accordance with at least one film grain block parameter, such as film grain size, intensity and texture. Performing such adaptive downscaling or adaptive deblocking filtering achieves improved performance at lower computational cost by avoiding modification of film grain block pixels in lesser affected areas.

摘要： In a multi-channel video transmission system in which channel video segments are operated on by corresponding channel video encoders to encode the video segments into frames organized into groups of defined frame types, an apparatus and method to cause a temporal staggering for the processing of a specific frame type among the various channels. In one preferred embodiment, the apparatus includes a frame counter to synchronize reset signals associated with the corresponding channel video encoders and a means for providing a timing offset to channel video encoders corresponding to a selected frame stagger for a particular corresponding channel.

摘要： The ATSC standard for digital television broadcast specifies a data Channel in addition to the normal audio and video channels. A methodology is provided for using the ATSC data Channel to broadcast MPEG-4 video streams, for which a new video service is created. The MPEG-4 streams can be encapsulated into MPEG-2PES (Packetized Elementary Streams) packets or directly into MPEG-2 transport packets. These mechanisms enable the synchronous broadcast of MPEG-4 streams for an ATSC digital TV system without a change to the ATSC standard when data casting. In a system for transmission of video and audio information, in which the system is constrained to operate pursuant to a given standard, including application of a given coding methodology, transmission of the information using a coding methodology that is independent of the coding methodology is provided through encoding the information into a plurality of increments (310) encoded according to the independent coding methodology; and encapsulating the encoded information increments into a payload portion (324) of transmission packets established according to the given standard.

摘要： A method and apparatus for improving the reception of digitally modulated signals. A main signal and a supplemental signal are provided in the transmitter. The signals may be substantially identical except that the supplemental signal is advanced in time with respect to the main signal. The main and supplemental signals are sent from the transmitter to the receiver modulated on a signal. At the receiver, the supplemental signal is stored in a buffer. If the main signal is undesirably changed during transmission, corresponding portions of the supplement signal are substituted for the undesired portions of the main signal.
