    摘要: A subscriber terminal apparatus for a television in an in-band subscription television system is provided. The subscriber terminal is adapted to receive a television signal including video, audio, and data information. A tuner of the subscriber terminal tunes channels of the television signal and an on-screen display control circuit selectively provides a display of characters on the television. A tuner control tunes the tuner to a channel having in-band data when the display of characters is provided on the television.

    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: A television menu system generates a television menu that is context sensitive based upon a service currently being provided to a user. In one implementation, a type of television service currently being viewed by a user determines whether particular menu items are presented to the user. In another implementations, determining which channel is being provided dictates whether particular menu options are included.

    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: A Digital Home Communication Terminal (DHCT) including a plurality of tuners, each of which can select one of a plurality of transmission channels provided by a Digital Broadband Delivery System (DBDS). The multiple tuners enable the DHCT to tune to a plurality of downstream media and data transmissions, thereby allowing a subscriber to tune simultaneously to multiple channels and content transmitted in the downstream transmission via the DBDS, an advantage over conventional DHCTs. The present invention enables subscribers to receive and view multiple channels and associated content, including electronic program guide information, at will. Furthermore, using the multiple-tuner DHCT of the present invention, subscribers can view multiple television stations and program content simultaneously, without degradation to television signals or pictures.

    摘要: The present invention comprises customizable, multimedia messaging over a subscriber television system, such as a cable or satellite system, utilizing a service independent framework. The present invention comprises a multimedia messaging (MMM) server generally located at a headend of a cable or satellite system, and an MMM client at a communications terminal located remotely with respect to the MMM server. A service provider or operator defines a message configuration that is utilized to present the message content to one or more subscribers. The message configuration includes parameters that control the presentation of the message content. The MMM server receives an MMM request from a service application, and in response thereto, generates an MMM request which is sent to the communications terminal, and more particularly, to the MMM client. The MMM client processes the MMM request, including the retrieval of any message content or the message configuration. The MMM client then presents the message to the subscriber. Since the MMM server and MMM client are platform independent, any number of different services may send uniquely generated and uniquely designed messages for presentation to a subscriber(s).
