摘要： A decoding arrangement for decoding pictures in an incoming video stream includes a noise generator for adding a dither signal containing random noise to the pictures after video decoding, to improve the subjective video quality. The noise generator adds noise to each pixel in an amount correlated to additive noise of pixels in a prior picture, either a previously displayed picture (i.e., a previously decoded picture to which noise has been added), or a previously decoded picture.

摘要： The addition of comfort noise to an image serves to hide compression artifacts. To facilitate comfort noise addition, supplemental information accompanying a video image contains at least one parameter that specifies an attribute regarding comfort noise. Typically, the supplemental information includes parameters that function to turn the comfort noise on and off, as well as to indicate the level of noise to add, based on the expected level of compression artifacts.

摘要： A method for enabling an access device to securely access content from at least a content provider and prevent a cloned access device from accessing such content. During registration of the access device with the content provider, the access device requests from a designated certificate authority a certificate having a public key of the content provider therein. Upon authentication of the certificate, the access device generates a key and uses the public key to exchange the key with the content provider. The key is then used for subsequent secure communications between the access device and the content provider. In this manner, a cloned device does not have access to the key and is unable to download content from the content provider.

The method includes dedicating at least one channel of a plurality of spread spectrum data channels as a broadcast channel. The frequency and phase of a carrier signal and of a chip rate clock of the at least one channel are synchronized for each of a plurality of cell transmitters of a respective plurality of base stations. The Information is then broadcast over the at least one dedicated channel from each base station.
