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.

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.

摘要： A television recording and playback system such as a personal video recorder digitally encodes a television program in handheld format and stores it in local memory. The stored handheld format television program can be outputted from the television recording and playback system, using either wired or wireless protocols, to a handheld device such as a personal data assistant for viewing on the handheld device. Alternatively the handheld device can output the television program to a different device such as another handheld device. The selection of programs for recording in large display format, handheld format, or simultaneously in both formats, can be by using a graphical user interface generated by the television recording and playback system or by the handheld device, and preferably with an electronic program guide containing information about programs to be, and being, broadcast.

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 decoding arrangement (10, 100, 1000) for decoding pictures in an incoming video stream includes a noise generator (16, 16') 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.
