摘要:
A method for recording audio information on a record carrier, typically a bitstream signal on an optical disc, is disclosed. In the method the audio information is encoded to compressed audio data having a variable bitrate, in particular using lossless compression. The compressed audio data is recorded at a transfer speed which is controlled in dependence on the variable bitrate. A transfer speed profile (53, 54, 55) is determined for items of audio information, e.g. for each track on a CD, in which profile the average transfer speed is higher than an average transfer speed minimally required to transfer the compressed audio data of said item. Stuffing data is added to the compressed audio data according to the transfer speed profile, and transfer speed profile information is recorded on the record carrier for enabling playback at a transfer speed as indicated by the transfer speed profile information. Also a recording device, a record carrier and a playback device are disclosed.

An apparatus includes inputs configured to receive first and second video signals. 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 further includes a combiner configured to combine the first and second video signals so as to obtain a composite video signal suitable for displaying on a display unit. The combiner combines the first and second video signal while the size of the images corresponding to the second video signal remains unchanged.

A system of controlling displaying of image data has a source device (10), for example a BD player, which processes source image data for outputting the image data in dependence of first display parameters, and has a user control (15) for controlling the display parameters. The image data is transferred from the source device to a display device (13), which displays the image data in dependence of further display parameters, and has a further user control (16) for setting the further display parameters. The source device provides a display control mask structure, which is transferred with the image data to the display device. The display device displays the image data in dependence of the display control mask structure by masking said setting of the further display parameters according to the display control mask structure. Advantageously in a 3D system the depth settings of the display device are controlled based on the display control mask structure based on data from the content author

A method of recording an encoded bit stream that represents video objects includes recording a collection of contiguously arranged video objects and management information about recorded video objects. The collection is partitioned into adjacent recordings that represent playable titles, where a playable title is defined as a playback sequence of all complete cells or a subset of complete cells of a recording in the order of allocation within the video object storage area on the disc. The method further includes generating a title list of titles sorted in the order of arrangement within the video object area on the disc. The method further includes defining a free space title that represents free space within the video object area and includes the free space title in the title list.

The present invention relates to a method of recording data on a dual-layer optical write-once disc (10), comprising the steps of: creating a first-layer video-data fragment (28) on a first layer (20) of the optical disc, the first-layer video-data fragment extending from a minimum first-layer video-data radius within a data zone of the disc to an outer radius within the data zone of the disc, the outer radius defining a layer boundary (38), creating a second-layer video-data fragment (40) on a second layer (22) of the optical disc, the second-layer video-data fragment extending from minimum second-layer video-data radius within the data zone of the disc to the layer boundary, writing video data (32) to the first-layer video-data fragment, starting from an inner radius of the disc up to a maximum first-layer video-data radius smaller than or equal to the layer boundary, writing video data to the second-layer video-data fragment, starting from the layer boundary, and if the maximum first-layer video-data radius is smaller than the layer boundary, writing a Buffer Cell (66) to the first-layer video-data fragment extending from the maximum first-layer video-data radius to the layer boundary. The present invention further elates to a dual-layer optical disc and an apparatus for recording data on a dual-layer optical disc.
摘要:
A system 100 includes a rendering apparatus 120, a server 110 and a network 130. Content items on the server are identified by respective server content locators, such as a URL. The rendering apparatus also has access to local content. Titles of the local content are associated with respective local content identifiers, such as title IDs. The system can generate and store a plurality of bookmarks, that each include a server content locator and a local content identifier. The rendering apparatus can render items of the local content and server content items that relate to the local content items. The rendering apparatus renders a server content item indicated by the server content locator of a bookmark conditional on having access to a local content title associated with the local content identifier of the bookmark.
摘要:
Methods and apparatus for encoding and decoding an audio and/or video signal, and a record carrier for use with such apparatus. One or more audio and/or full motion video signals, e.g., a video signal, and possibly computer data) are recorded on an interactive compact disc. The video signal is encoded into code blocks of variable lengths, each corresponding to a picture or picture pair. A decoder delay time parameter is associated with one or more of the code blocks, which parameter represents a length of time (i.e., a delay time) with which the corresponding picture of a code block is to be displayed after that code block has been received by a decoding apparatus.
摘要:
An optically readable disc like a compact disc contains a sequence of full-motion video scene digital video blocks, having differing lengths. Each video block contains the entire encoded picture information for at least one picture of the sequence. A header in each video block contains reference information referring to the location of a predetermined video block in the series of blocks, so that this information permits a playback device to recover from a slow-motion or freeze mode by reading from a desired location in the predetermined video block.

One or more audio and/or full motion video signals, e.g., a video signal (and possibly computer data), are recorded on an interactive compact disc. The video signal prior to being recorded is encoded into code blocks of variable lengths, each corresponding to a picture or picture pair. A decoder delay time parameter associated with one or more of the code blocks, which parameter represents a length of time (i.e., a delay time) with which the corresponding picture of a code block is to be displayed after that code block has been received by a decoding apparatus is determined and included in the video signal prior to being recorded.
摘要:
A method and transmitting system for transmitting an information signal, a receiving system for receiving the transmitted information signal, and an information carrier on which the information signal is recorded. The information signal is transmitted from the transmitting system to the receiving system. The information signal includes basic information and overlay information. The basic information includes video content that is adapted to be displayed on a display device. The overlay information includes overlay content and time information. The overlay content is adapted to be overlayed on a portion of the displayed video content for a period of time during the displaying of the video content. The overlay content, and not the portion of the displayed video content, appears visible during the period of time. The time information is indicative of the period of time.
