Preferred systems and methods provide a personal channel for broadcasting personal content to televisions over a network, such as a fiber optic access network. A service provider assigns a personal channel identifier to a broadcaster. This identifier allows viewers to tune to the personal channel. The broadcaster sends personal content to the service provider together with a list of authorized viewers for that personal content. The service provider stores the personal content and makes it available as specified by the subscriber for viewing. When requested, the service provider sends the personal content to the specified set top boxes on the assigned personal channel identifier. By tuning the set top box to the broadcaster's channel, viewers may view the personal content on television as though it were broadcast from any network television station.

In a digital broadcasting network, a mobile terminal receives hierarchical ESG data relating to available broadcast programs adjacent network areas. The terminal is operable whilst receiving a first program from a transmitter in a first network area for detecting a need for handover to a second network area, and for then determining from the ESG data if the same program is available in the second network area If it is, the terminal then receives the program from a transmitter in the second network area. Otherwise, it determines one or more programs which are similar to the first program, and presents them on a display for selection by a user. This involves determining which programs have an identifier in common with the first program. The identifier can be any one or more of a program identifier, a service identifier, a channel identifier, a category identifier and a genre identifier, for example.

Techniques are disclosed in which a parameter used for scrambling packet data is changed. If the initial scrambling of a packet causes a killer packet to be generated, the packet is re-scrambled using a different value for the parameter, so that a killer packet is avoided. In a network that employs frequency-hopping spread spectrum communications, a channel identifier can be employed as an input to the scrambling algorithm. In this implementation, a given packet of data will be transmitted on one channel with a first sequence of bits when it is scrambled, and on another channel with a different sequence of bits. If the scrambled packet for one of these channels results in a killer packet, it is statistically unlikely that it will also be a killer packet when it is re-transmitted on the other channel.

A wireless communication system having a base unit and a plurality of remote transceiver units utilizes a dynamic time slot assignment scheme for channel access. The base unit receives and processes a channel access request message from a remote transceiver unit and prepares a channel measurement request message in response. If an Mth time slot of a time frame is available, the base unit sends this message in the Mth time slot and receives a message having channel measurement data in the Mth time slot of the next time frame. On the other hand, if the Mth time slot of the time frame is already reserved, the base unit sends the message in an Nth time slot of the time frame and receives a message having the channel measurement data in the Nth time slot of the next time frame. The base unit selects, based on the channel measurement data, an appropriate channel for communication for the remote transceiver unit. Continuing with use of the dynamic slot assignment, the base unit sends a message having a channel identifier associated with the selected channel and receives an acknowledgement from the remote transceiver unit in response.

An access that the computing device is allowed to have to the communication channel is determined based at least in part on both whether the current security policy is satisfied by the use policy and whether the identifier of the communication channel and the use policy are verified.

A network interface for secure virtual interface data communication includes a doorbell circuit, a processor, memory, and a bridge circuit. The doorbell circuit responds to physical I / O addresses of the host that are mapped by a memory management unit by a registration process. An application program seeking to use a channel of a virtual interface must register the virtual address of host memory where data for communication is or will be stored and register the virtual address of a page of I / O addresses. Access to the doorbell functions and to the host memory via the memory management unit are therefore denied when the requesting process identifier does not successfully compare with the process identifier for the process that performed the registrations. A password may be stored in the network interface in association with a virtual interface (VI) channel identifier and stored in association with the virtual to physical map used for VI communication. The network interface may abandon a requested or implied data communication function when passwords so not successfully compare. Methods for virtual interface (VI) communication performed by an application program may include one or more of the steps of (a) establishing a VI channel where physical I / O addresses of a network controller are secured; (b) registering host memory for use with a VI channel where physical memory addresses are secured; (c) describing blocks of host memory with reference to a memory handle; and (d) accomplishing data communication of a described block of host memory via an established VI channel where the data and controls of the VI channel are secured and the data and controls of other VI channels are secured. Security is provided against both erroneous operations and operations intentionally effected by rouge processes.

Admission control for a communications link involves maintaining a record at each end of the link of which channels on the link are free and allocating a free channel so that the probability of both ends allocating the same channel to different information flows is controllable. The record of channel identifiers is searched sequentially in different directions by the respective ends of the link to minimise the probability of simultaneous allocation before the records at each end are synchronised. New requests for admission to the link are allowed a different bandwidth threshold than requests for changes to existing connections already admitted to the link.

Communications are translated using a translation service which employs the attributes associated with the private key and the public key combination to provide response information in a designated language to enable multi-lingual real-time communications.
