A method of operating a digital television decoder is disclosed. The decoder includes a memory, the memory storing onboard software, and the decoder is operable in a run mode to execute the onboard software. The method comprises: activating a power saving mode on the decoder; and upon activating the power saving mode: maintaining power to the memory; suspending execution of the onboard software; acquiring an execution context of the onboard software; updating the execution context of the onboard software to form an updated execution context; and saving the updated execution context in the memory.

Digital television decoder

A method of transmission of application data () in a digital transport stream characterized in providing an application data table () containing information regarding the applications () carried in each service () within the transport stream. The application data table () may conveniently be designated by a fixed PID value and a TID extension value varying in dependence on the bouquet of services chosen. The use of a single application data table to provide information across all services within a bouquet provides a number of advantages, in particular when deciding whether or not to maintain certain applications when switching between services.

Application data table for a multiservice digital transmission system

A parental control method, including receiving a channel selection command from a user to select from a plurality of channels for playing, each of the channels having a plurality of programming content, performing a parental control procedure prior to allowing playing of the programming content of one of the channels, during at least one specific timeslot, and allowing playing of the programming content prior to performing a parental control procedure for at least one of the following the one channel outside of the at least one specific timeslot, and another one of the channels. Related apparatus and methods are also described.

In a digital television system, a receiver/decoder (or 'set-top-box') can download one or more of several applications which can be run by the receiver/decoder to provide interactivity with the user. The applications include: an Internet browser application which uses a PSTN connection to make Internet requests and the television signal path to receive Internet responses; a shopping application operable in an 'impulse' mode and a &#x201c;catalogue&#x201d; mode; a banking application; a quiz application which runs in synchronization with a quiz television programme; a magazine browser application; and a weather or traffic application.
