Abstract: A PVR is selectively granted access to a hard disk drive. The HDD generates a random number, encrypts it with a key known to the PVR, and sends it to the PVR, which decrypts the number and increments it by one to render a new number. The new number is encrypted with the key and sent back to the HDD, which decrypts the new number, decrements it by one, and compares the result to the original number, granting the PVR access only when a match occurs.

Abstract: An on-location local multicast distribution system and business method therefor. Contemporaneous information is continuously provided to a local distribution unit on a particular event (e.g., a NASCAR race) from multiple input devices, such as video cameras and microphones. The distribution unit simultaneously transmits audio, video and event specific information to multiple uniquely identifiable output devices, each in the hands of a registered attendee. The input devices are in wireless Communication with the distribution unit and the distribution unit is in wireless Communication with the output devices. The uniquely identifiable output devices include a display such as a liquid crystal display and may be for example, a personal digital assistant (PDA). Registered attendees may selecting which of the multiple inputs are received.

Abstract: High definition (HD) video may be sent from, e.g., a laptop computer on a table in a room to a video projector mounted on the ceiling using a 60 GHz high capacity (2.5 Gbps) wireless link. At this frequency and data rate, the signal is so short range and directional that low power may be used and the video may be transmitted in an uncompressed form such that so much data is transmitted each second that bootlegging the content is essentially untenable. No wiring between the HD video source and the HD video display is necessary.

Abstract: A television Set-top box based content server consistent with certain embodiments of the present invention has a receiver that receives a transport stream containing data representing content in packets, wherein the packets are identified by packet identifiers (PIDs). A PID filter selects packets having a specified PID. A mapper maps packets having the specified PID to an Internet Protocol (IP) address. The mapper uses the PID as an index to a translation table and retrieves the IP address from the translation table. A packet converter converts the packets identified by the specified PID to an IP packet having the IP address. A router, such as a wireless ultra-wideband router, routes the IP packet to a recipient according to the IP address.

Abstract: An adapter can be used to connect a standard connector on an electronic device, such as a Set-Top Box (“STB”), with a specific connector on an external module, peripheral, electronic device, bus, cable, wire or the like that is to be connected to the electronic device. For example, different adapters can provide means for connecting a standard connector on an STB with any of a Point-of-Deployment card or module, a smart card, a PCMCIA card or a Memory Stick®. Consequently, the STB (or other electronic device) need not be manufactured with connectors configured for connecting all possible peripheral devices. Additionally, the STB (or other electronic device) need not be manufactured in different models with various combinations of connectors for the possible peripheral devices.
