A system for delivering digital program signals from a center to subscriber locations using a satellite with a first satellite transponder, the system comprising a center, remotely located from the subscriber locations, wherein more than one digital program signal is processed for transmission to a first satellite transponder, a first cable headend, comprising a first satellite dish, wherein the digital program signals are received from the first satellite transponder; and a means, connected to the first satellite dish, for sending the digital program signals from the first cable headend to the subscriber locations; and a first terminal, located at each subscriber location, wherein the sent digital program signals are received from the first cable headend and at least one digital program signal is processed for subscriber viewing.
摘要:
A technique is provided for enabling an index to data recorded in a recording medium such as a cassette to be read out without mounting the recording medium on a reproduction apparatus to reproduce the data. When a cassette (100) is inserted into a compartment in a VTR (41), a switch in the VTR is pushed by a case of the cassette, detecting the insertion of the cassette into the compartment. At that time, a signal indicating the insertion of the cassette into the compartment is supplied to a microcomputer from the switch. Notified by the signal, the microcomputer issues a command to a reader/writer, requesting the reader/writer to read out information on data from a memory card mounted on the cassette for recording the data through an antenna. With the cassette located outside the compartment, on the other hand, the microcomputer issues a command to a reader/writer, requesting the reader/writer to read out the information from the memory card through another antenna.

A system is described that allows simultaneous display on a display screen of bit-map, graphic, still video picture, motion video picture or background. A frame memory containing the page to be displayed is located in an the SDRAM. A display controller reads the frame memory block by block and transfers the data to a Fifo. For each pixel, the OSD decoder reads the bits required to display the current pixel from the FIFO. The number of bits per pixel varies during the display depending upon the mode. The pixel selector and its controller select the bits of data from the FIFO to form the current pixel.

摘要:
Method of communication for an intelligent digital, audiovisual playback system. The method for communication between a central server and a computerized jukebox is characterized in that it operates in a conference mode and includes sending, prior to any transaction, a header including the identity of the destination target, the originator identity and the packet size; sending the response of the server as a data packet, each packet from the server being encrypted by the code which identifies the jukebox software. The jukebox receives and then decrypts the data packet. At the same time the packet controls the data received by the cyclic redundancy check method (CRC) and sends an acknowledgement of receipt to the server stating that the information received is accurate. The server can then prepare a new packet addressed to the unit.
摘要:
Payment-based audiovisual playback system characterized by comprising a microprocessor unit, primarily including storage means for storing inter alia in digital form the visual and sound information to be used, and associated, through a number of interfaces, with display means for sound playback which provide a multimedia environment. The unit is controlled by a multitask operating system including a library of integrated tools and services in the storage means. The system is also associated, through an interface, with a telecommunications modem and is connectable to an audiovisual information distribution network by a telecommunications modem and telecommunications links, the telecommunications functions also being managed by the multitask operating system.

摘要:
A distributed computer system is disclosed which includes a central location (10) and a plurality of remote locations. A central location computer system generates a module (14) which includes a data section (144) containing a plurality of data units. Each of the data units is either a minimum addressable data unit or a longer data unit. Each longer data unit contains a plurality of minimum addressable data units. The module also includes a swap section (146) containing data identifying locations of longer data units within the data section. A remote location computer (70) system receives a module, and contains a loader (40). The loader swaps the minimum addressable data units of the longer data units in the data section. A transmission link (30), transmits the module from the central location computer system to the remote location computer system.
