Embodiment Construction

[0024] The term "module" disclosed in the present invention is defined as a logical entity used for file transmission. The (DSMCC) object carousel is generally designed to broadcast a complete directory / file structure. This broadcasting is done by compressing the files into objects and transferring these directory names and the files themselves as objects of a specific type, ie directory objects and file objects. A directory object preferably contains the file names and file paths under the directory. File objects contain files. These objects are in turn transferred in groups based on their size, such as groups of two or three. These groups are logical entities called "modules". When these modules are received at the receiving end, some modules may contain objects which in turn compress the file and some do not need to be recorded and some require forced recording. The invention allows the receiving end to determine which modules need to be recorded forcibly and which modu...

Abstract

A method of transmitting interactive television, whereby interactive television applications are transmitted inside application-modules. These modules are transmitted in a broadcast stream. Recordingsystems cannot decide which modules are to be recorded. Therefore storage related information of said modules is signalled in the broadcast stream. Module identification information is implemented inthe Application Information Table (AIT) and / or in the Download Information Indication (DII) message. Thus information is included in the broadcast stream concerning categories stating whether application modules are mandatory, optional or forbidden to record. Alternatively properties of a module are chosen from Code / Data / Both and / or Fixed / Variable. Recording systems use this information do decideif application modules are to be recorded or disregarded. Alternatively, application module identification information is transmitted in said broadcast stream. A module identification number is used to avoid multiple recordings. Application modules having the same category are preferably grouped together.

Description

technical field [0001] The present invention generally relates to the field of interactive television, more specifically to the recording of interactive television content, and especially to the processing of applications in the field of interactive television content recording. Background technique [0002] Interactive television (iTV) is becoming more and more popular. An example of interactive television is the Multimedia Home Platform (MHP), a Digital Video Broadcasting (DVB) standard for integrating digital television (DTV) interactivity and access to the Internet and the World Wide Web. DTV service providers offer a large number of audio-visual (A / V) television programs and applications that allow viewers / users to interact with television settings and their content. [0003] Similar to today's video recording devices in analog broadcast television that use video tape to record broadcast streams, digital video recording devices for interactive television use hard disks...
