摘要： Systems and methods are disclosed for providing downstream signals to a plurality of receiver networks. A receiver network (i.e., a networked multimedia system) includes a splitter/isolation module (SIM), a primary set-top terminal (STT), and at least one remote device. The remote devices communicate with the primary STT via the SIM over coaxial cable. Accordingly, the remote devices utilize some or all of the features including hardware and software that are included in the primary STT via the networked multimedia system.

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： There is disclosed a signal scrambling transmission system in which the data is scrambled at the transmit end by logically combining the data with a pseudo random sequence generated by a ROM prior to transmission. The data is recovered at the receive end by logically combining the scrambled data with the same pseudo random sequence generated by a ROM. The ROM at the transmit end is divided into frames with a synchronization word and a frame count (index) word embedded in each frame. The synchronization word and index word are transmitted with each frame of data and are used to synchronize the ROM at the receive end with the incoming scrambled data. The transmit end ROM is divided into 32 frames each being 4,096 bits long. Each frame has a 27-bit synchronization word, a 5-bit index word, and 4,064 bits of pseudo random sequence.

摘要： A method of downloading on-screen graphics and captions to a television terminal for display comprises a system manager computer and data transmission apparatus coupled thereto for transmitting program code, cube definition data and downloadable display commands to the terminal. Manufacturer intervention is minimized in that the system operator scans a graphic image to create a bit map and encodes the bit map into the cube definition data. The system manager also generates display control commands for downloading to the terminal without manufacturer intervention which control when, how long, where and how the graphic image is displayed. In this manner, a system operator may generate a custom screen for display representing their particular logo or service name. Moreover, screen data for different service names are addressably downloaded to different groups of subscribers to the different services. The program code, the cube definition data and the downloadable display commands may be globally or addressably downloaded via in-band video, in-band audio or outband data transmission. The output graphics for display may be accompanied by a predetermined audio signal.

摘要： A subscription television system is provided that transmits a plurality of television signals to a plurality of subscribers. The television signals include pay-per-view programs (purchased by feature) or near-video-on-demand programs (purchased for a period of time for unlimited viewing) that are provided only to subscribers that purchase the programs. Data representing an electronic programming guide is also transmitted. The electronic programming guide can be displayed by a subscriber terminal at the subscriber's location. The electronic programming guide is a grid listing television programs by date, time and channel. A subscriber can select programs for watching or recording from the electronic program guide. Moreover, the subscriber can purchase pay-per-view or near-video-on-demand programs from the electronic programming guide.
