A method of providing interactivity over a set of multiple optical storage media (90, 91) is disclosed. A logical unit, such as a playitem of a playlist is provided on a storage medium (90) of the set of optical storage media (90, 91), comprising information about contents stored on at least one other storage medium (91) of said set of optical storage media. Furthermore, a corresponding optical disc reading apparatus, optical storage medium, and a computer-readable medium, are disclosed.

A device for recording records digitally encoded video information on a record carrier according to a predefined recording format, such as BD. The device has an input unit (91) for receiving a data stream comprising the video information and application data objects contained in messages, such as DVB-MHP. The device has a message unit (92, 94) for extracting the messages from the data stream. The messages are stored in a message file as a series of the messages for the program separate from the video information. The device also has a parsing unit (95) for generating application control information that includes accessing information for accessing the messages in the message file. The application control information is stored in a message info file.

A method and apparatus for improving the performance of the running of a stored interactive application on a de-coding apparatus is disclosed. The recorded program which is associated with the stored interactive application is run, wherein the program and interactive application are stored in a storage device. The running of the stored interactive application is controlled using a second application.

A method and apparatus for the handling of a recorded data stream and associated linear application is disclosed. Linear real-time playback of the data stream and running of the linear application is commenced from a starting point thereof. On entering a non real-time playback phase, select frames from the data stream are mapped using a mapping scheme to create an interactive trick play stream. Events from the linear application are mapped into the interactive trick play stream using the disclosed mapping scheme.
摘要:
A method and device for storing an interactive television program for playback at a later point in time, wherein said interactive television program comprises at least one interactive television application. The applications are transmitted inside modules (11, 12) through a data carousel (2) within a transport stream (20). The method comprises receiving the transport stream, parsing the stream for application modules and storing them as a storage stream on a storage medium (31). The storage stream is stored separate from said transport stream (20). The data or object carousel is recorded outside the Transport Stream and recorded like a stream, preferably as a single file. This file is a sequence of modules with some header information preceding the modules making playback faster as the information needed to obtain the objects from a module is located directly in the header of that module. Furthermore, the solution according to the invention solution is platform independent.
摘要:
The invention relates to an apparatus for receiving a first and second video signal. The first video signal represents a sequence of images having a first size, and the second video signal representing a sequence of images having a second size, the second size being smaller then the first size of the images. The apparatus combines said first and second video signal so as to obtain a composite video signal suitable for displaying on a display unit. The signal combination means being adapted to combine the first and second video signal while the size of the images corresponding to the second video signal remains unchanged.
摘要:
For encoding externally input AV signal to MPEG-TS that enables quickly conversion from MPEG-TS to MPEG-PS, data unit (Multiplexing Unit) is defined which includes a plurality of packet and has data size corresponding to data amount of one pack in MPEG-PS, and MPEG-TS is encoded for each defined data unit. Furthermore, time stamp information (ATS) added to a packet of MPEG-TS which is converted to MPEG-PS and time stamp information (SCR) added to a packet of the converted MPEG-PS are correlated with a predetermined formula.

摘要:
Method to enable a local system time clock counter (STC) of a receiving recording device to lock to program clock reference (PCR) information comprised in a received real time sequence of information signal packets, such as MPEG2 Transport Stream packets. The method comprising determining the number of cycles between arrival of the first information signal packet and the arrival of the information signal packet comprising the first Program Clock Reference (PCR) information. This information is stored as an attribute of the stored sequence.
