摘要： An embodiment of a method for secure escrow and recovery of media device content keys includes generating, with a first processor of a media device, an escrow key for encrypting a plurality of content keys, the content keys for encrypting instances of media content. The first processor of the media device encrypts the escrow key with a public key of a key clearinghouse. The escrow key, encrypted with the public key of the key clearinghouse, is stored in a storage location outside of the first processor of the media device.

摘要： A conditional access device is provided. The conditional access device typically includes conditional access decryption, interface, timing and control logic. The conditional access decryption logic decrypts an incoming signal for use in a consumer electronics device in accordance with previously received entitlement management messages. The interface logic receives a control signal including an entitlement management message window from a headend control system through a receiver in the consumer electronics device. The timing logic asserts an awake signal responsive to the entitlement management message window becoming active. The control logic sends a request to the consumer electronic device to activate a receiver coupled to the headend control system in expectation of receiving an entitlement management message via the control signal in response to assertion of the awake signal. The control logic also communicates the entitlement management message to the conditional access decryption logic. Other systems and method are also provided.

摘要： A subscriber terminal includes a receiver for receiving a television signal including video, audio and data information. A channel of the television signal may be selected for display on the television. A memory stores channel identification information such as channel identifiers. The channel identifiers include at least one display character. A processor establishes a relationship between channel identification information and channel numbers associated with channels of the television signal. An on-screendisplay control circuit controls the display of character information on the television and has the capability of overlaying the channel number and the channel identification information on the video portion of a selected channel displayed on the television for a predetermined period of time. Program identification information such as program titles may also be displayed. Alternatively or additionally, the channel identification information may be displayed on a display such as an LED display of a subscriber terminal.

摘要： A television system having sync suppression scrambling and descrambling which includes in band and out of band signaling methods. The in band signaling method modulates the IF sound carrier of a premium video channel with timing and data pulses (Figs. 2A, 2B) while the out of band signaling method modulates the previously modulated IF sound on a separate carrier onto a separate out of band data carrier (Figs. 3A, 3B). The in band signaling method uses a descrambler which tunes a channel before demodulating the timing and data pulses from the sound carrier while the out of band signaling method tunes a selected data carrier to demodulate the timing and data pulses. In both methods, the timing pulses are used to restore the levels of the synchronization pulses in the sync suppressed video signal, and thus descramble the signal, while the data pulses are used for addressable messaging to the descrambler including authorization. The out of band descrambler provides broadband sync restoration for a particular channel and thus does not need a broadband tuner for the video signal.
摘要翻译：具有同步抑制加扰和解扰的电视系统，其包括频带和带外信令方法。带内信令方法利用定时和数据脉冲调制优质视频信道的IF声音载波（图2A，2B），而带外信令方法将单独载波上的先前调制的IF声音调制到单独的带外数据载体（图3A，3B）。带内信令方法使用解扰器，其在解调来自声载波的定时和数据脉冲之前调谐信道，而带外信令方法调谐所选择的数据载波以解调定时和数据脉冲。在两种方法中，定时脉冲用于恢复同步抑制的视频信号中的同步脉冲的电平，并且因此解扰信号，同时数据脉冲用于包括授权的解扰器的可寻址消息传送。带外解扰器为特定信道提供宽带同步恢复，因此不需要用于视频信号的宽带调谐器。

摘要： Apparatus for providing a user friendly interface to a subscription television terminal comprises a key pad arranged into a plurality of key groupings and an on-screen display controller for generating a plurality of screens for display on an associated television receiver. Five such key groupings are segregated from one another and comprise function keys, initialization keys, channel keys, audio keys and digit keys. The digit keys may be most conveniently arranged in a two dimensional matrix corresponding to a key pad of a conventional tone dialing telephone. Each of the other key groupings may be arranged linearly and differentiated by the use of color or boxes. A method of initializing the cable television terminal comprises the steps of generating a display of a menu structure, actuating the movement of a cursor in one direction through choices presented by a menu by use of a cursor key, and actuating a selection of a menu choice via actuation of a select key. For example, a sleep timer may be implemented in a subscription television terminal for turning off power to an associated television set after a predetermined period of time. Parental control of received channels can be established such that only those having knowledge of a particular code may view the parentally controlled channel. Other features of a terminal in accordance with the invention include messaging, establishing a favorite channel list, pay-per-view, program timing, and terminal control.

摘要： A display system for providing programmable on-screen displays for a subscriber terminal, includes a control processor (128) and a display processor (127) which generates such displays from stored display information and display attributes. The control processor (128) executes display routines to configure the display processor (127) and to load the display data into a display memory. The display routines, display attributes and display data are programmable and can be varied for optimal use of the display processor. In one implementation, such information can be modified by changing the programming in non-volatile memory of the subscriber terminal, either by switching ROM (134) or Flash EPROM ICs (326) or by a plug in module (138). Another implementation includes downloading the information with other executable code and data in the read/write portions of the non-volatile memory. A third implementation provides specialized display transactions for the information which, in a preferred embodiment, envisions a high level screen definition language whose commands can be compiled into the formats of the display routines, display attributes and display data.

摘要： An auxiliary device control for a subscriber terminal includes a four wire ribbon cable (306) defining a bidirectional communication and data interface from the terminal (40) to one or more auxiliary devices (310, 312, 314). A communication and data protocol for the bidirectional transfer of instructions, status, and data over the interface includes an address field, command or reply field, data length field, and checksum field (fig. 6) transmitted at 9600 baud. In a preferred implementation, the auxiliary device to be controlled is an IR peripheral controller (300) which can tune a VCR (350), and switch it on and off. Several transactions in the communications and data protocol are used to effect the operation where a control VCR command and reply transaction cause the control of the tuning and recording of the VCR. A set-up VCR command and a brand reply transaction is used to provide information to configure the controller with brands and model of the VCRs. A program event code command and a program event timer reply transaction provide for the automatic recording of a program event based on an event code listed in a television schedule. A channel map command and a reply transaction provide for the downloading of the local cable system channel line up into the controller.
