摘要： A cable television system provides conditional access to services. The cable television system includes a headend from which service “instances”, or programs, are broadcast and a plurality of set top units for receiving the instances and selectively decrypting the instances for display to system subscribers. The service instances are encrypted using public and/or private keys provided by service providers or central authorization agents. Keys used by the set tops for selective decryption may also be public or private in nature, and such keys may be reassigned at different times to provide a cable television system in which piracy concerns are minimized.

摘要： A reprogrammable subscriber terminal of a subscription television service which can have the control program code of its control processor modified by downloading new program code from the headend. The control processor stores a boot program in an internal read only memory. Upon start up and resets, the boot program determines whether the control program should be changed from a command sent from the headend. The command, termed a parameters transactions, includes the number of expected download program code transactions required to complete the control code modification, the memory space areas where the code is to be loaded, and the channel over which the download program code transactions are to be transmitted. The channel is tuned and when the boot program receives all the download program code transactions accurately and stores them, the boot program will cause the control program to be restarted at a selected address of the new or modified control program code which has been downloaded. The boot program may download code to different configurations of subscriber terminals including those with Flash EPROM or extended memories from plug-in expansion modules.

摘要： This invention discloses a new and improved method of scrambling video signals by inversion of the video information by splitting the sync pulse into plural portions and transmitting each portion of the sync pulse at a predetermined level. This improves the quality of the recovered video compared with other video inversion systems by rendering the video less sensitive to variations in the modulation depth of the modulator carrying the inverted signal, the demodulation sensitivity of the demodulator and the stability of the recovery circuits. The invention further provides additional security against pirating by allowing the scrambling circuit to operate in diverse modes, each of which will cause a TV to react differently should a conventional pirating device be employed. The invention also renders the signal capable of being transmitted with unmodified modulators of the type normally employed in the CATV industry.
摘要翻译： 本发明公开了一种通过将同步脉冲分成多个部分并将同步脉冲的每个部分以预定水平传送的方式来反转视频信息来加扰视频信号的新方法。 这通过使视频对携带反相信号的调制器的调制深度，解调器的解调灵敏度和恢复电路的稳定性的调制深度的变化较不敏感，从而提高了与其他视频反转系统相比的恢复视频的质量。 本发明还通过允许加扰电路以各种模式操作来提供额外的抗盗版安全性，如果采用传统的盗版装置，则各种模式将导致电视机的反应不同。 本发明还使得能够利用在CATV工业中通常使用的类型的未修改的调制器来传输信号。

摘要： The present invention provides a method and system for accessing services in a television system. In one implementation, a DHCT presents a user a menu containing a plurality of selectable link representations corresponding to separate services or applications offered by the cable television system. The user navigates the menu with a remote device and selects a desired service by choosing the selectable link representation corresponding to the desired service or application. The DHCT receives the user input, translates the selectable link command into an executable call, and activates the service or application corresponding to the selected link representation from the menu chosen by the user.
摘要翻译： 本发明提供一种用于在电视系统中访问服务的方法和系统。 在一个实现中，DHCT向用户呈现包含对应于由有线电视系统提供的单独的服务或应用的多个可选择链接表示的菜单。 用户使用远程设备导航菜单，并通过选择与期望的服务或应用相对应的可选择链接表示来选择期望的服务。 DHCT接收用户输入，将可选择的链接命令转换成可执行的呼叫，并从用户选择的菜单中激活与所选择的链接表示相对应的服务或应用。
