摘要： Partial pre-encryption with network-based packet sorting. A video-on-demand (VOD) delivery system for delivering encrypted transport streams to incumbent and overlay set-top boxes utilizes a packet picker/duplicator for sorting selected packets from non-selected packets, duplicating the selected packets, and encrypting one of the pair of duplicated selected packets according to an incumbent encryption scheme. A VOD file server stores the transport stream from the packet picker/duplicator. A network sorter sorts the unencrypted selected packet from the non-selected packets and the encrypted selected packet. The network sorter also sorts the encrypted selected packet from the non-selected packets and encrypts the unencrypted selected packets and the non-selected packets according to an overlay encryption scheme and then sends the transport stream to an overlay set-top box. The network sorter is also responsible for combining the non- selected packets and the incumbent encrypted packets and to send the transport stream to an incumbent set-top box.

摘要： An apparatus and method is described for transmitting, receiving and communicating program data signals which are combined with digital data signals. Preferably, the present invention compresses 30 digital audio signals (10-1 - 10-n), multiplexes them with title, track, artist, record label, year, etc., program information (20-1 - 20-m and 30-1 - 30-K) and transmits the combined signals via satellite (50) to a receiving station (60). The receiving station demultiplexes (70) the signals and sends them via a cable distribution system to a subscriber's digital music tuner (100). This tuner further demultiplexes (143) and decodes (147) the signals so that the digital audio signals may be converted to analog (160) and output for listening, while the corresponding data signals are communicated to the subscriber. In an alternative preferred embodiment, the program data signals are transmitted to a remote control receiver (200) where they are displayed. The system described in the present invention may be used for transmitting video, software or games with program data to subscribers.

摘要： A remote control system including a hand held remote control unit (200) with an alphanumeric information display (209), for controlling and communicating with a first controlled device (100), such as a digital music tuner connected to a community antenna television (CATV) cable, and for controlling a selected one of a plurality of second controlled devices (300), such as CATV set-top-units, VCRs, or televison sets. A first, high speed, error free display information communications protocol is utilized for transmitting program content or other information from the first controlled device (100) to the remote control unit (200) for display. A second or control communications protocol is utilized by the remote control unit (200) for controlling the first controlled device (100) and a selected one of the second controlled devices (300). The first controlled device (100) utilizes a first clock signal embedded in digital music signals provided via the cable to derive clocking signals for implementing the display information communications protocol, resulting in an efficient, low cost electronic design.
