摘要： A bit stream includes playback data having an associated clock rate and a variable reference clock that is synchronized to the bit stream. A playback clock recovery signal and a data recovery signal are generated in response to the received reference clock. A playback clock frequency signal is generated in response to the playback clock recovery signal. A recovered playback clock is generated by using a divide by M divider, wherein the value of M used by the divide by M divider is determined in response to a programmable multiple of the clock rate associated with the playback information.

摘要： This invention is a video line encapsulation protocol which allows multiple low definition video streams to be combined into a single super frame of high definition video data. Each super frame is formed of individual lines from plural lower definition video input signals. The high definition video frames include meta data in each line identifying the video input source, line and frame. This meta data enables the super frames to be separated into their component input signals within a video processing digital signal processor.

摘要： A video decoder (10) for receiving an input video signal and producing output signals for a digital display (12), and involving automatic gain control (AGC) functions (20, 28), is disclosed. For each of the front-end and back-end AGC functions (20, 28), the AGC gain value applied is modified according to measurements of several attributes of the video signal, such as sync height, color burst amplitude, composite signal peak amplitude, and luma signal peak amplitude. The measurements are made, and the AGC gains are modified, on a frame-by-frame basis. Preferably, the AGC is modified using the one of the signal attributes that indicates the lowest gain. The back-end AGC function (28) modifies its gain to unity if the front-end AGC function (20) selected the luma signal peak amplitude for modifying its gain. A method for adjusting the rate of change of the AGC gain is also disclosed, in which gain increases are delayed and slowed following an AGC gain decrease because of an image-dependent signal attribute.

摘要： A method for protecting secret keys, such as HDCP device key sets, during the manufacturing process is disclosed. In particular, the present invention comprises a method for securely sending and receiving data, such as HDCP device key sets, for use in a cryptosystem. In operation, a first party, referred to as a sender (107) is to send original data (106) to a second party, referred to as a recipient (100). To facilitate the secure transmission, the recipient (100) randomly generates (101) a session key (102) and encrypts it with its private key-encryption key (103). The recipient then securely sends both the encrypted and unencrypted session keys to the sender. The sender (107) then encrypts the original data (106) using the unencrypted session key (102) and includes the encrypted data (108) along with the encrypted session key (104) to the recipient (100). The recipient (100) then decrypts the encrypted session key (104) using the private key-encryption key (103) and then decrypts the original data (106).
