Abstract:
Operation of a video cassette player is facilitated by providing a VBI decoder which decodes information, such as title, channel, date, time and length of broadcast programs and utilizing the information in providing directory of the programs as well as control of the VCR. The video cassette player is also provided with a VBI encoder for inserting control as well as directory information into the tape, either in the VBI portions of the video track or in the control track.
Abstract:
A directory of programs recorded on a cassette tape is provided to facilitate recording and reviewing of the programs and allocating and deallocating of space on the tape. The directory is either stored on the cassette tape itself or on an external memory. Designs of the various components for providing and maintaining the directory are also disclosed.
Abstract:
Provided is a data structure that makes it possible to easily understand a relationship between pre- and post-editing moving image data on a frame-by-frame basis. A data file has an area for moving image data, and an area, different from the area for the moving image data, for associated information related to the moving image data. The associated information includes identification information for identifying a data file for moving image data related to the moving image data, and information specifying a segment of frames of the moving image data.
Abstract:
There are disclosed various methods, apparatuses and computer program products for video encoding. According to an embodiment,an encoding method comprises including a static media item into a container file; including one or more media tracks into the container file; indicating, in the file, that the static media item and one or more entities form a group; and indicating, in the file, a grouping type for the group. According to an embodiment, a decoding method comprises parsing, from a container file, that a static media item and one or more entities form a group; parsing, from the container file, a grouping type for the group; determining a processing for the static media item and the one or more of the entities based on the group and the grouping type.
Abstract:
A device for processing video information has an input unit (112) for receiving the video information having low dynamic range [LDR] video data and/or high dynamic range [HDR] video data, and a video processor (113) for generating a display signal for display in a LDR display mode or HDR display mode. Graphics data is processed for generating an overlay for overlaying the video data. The input unit receives graphics processing control data comprised in the video information, the graphics processing control data including at least one HDR processing instruction for overlaying the graphics data in the HDR display mode. The video processor is constituted for adapting the processing when overlaying the graphics data in dependence on the specific display mode and the HDR processing instruction. Advantageously the source of the video information is enabled to control the processing of graphics in HDR display mode via the HDR processing instruction.
Abstract:
A video decoder User interface system supports decoding, recording and other applications including the addition of new decoder features and the conversion of data formats between read-only and recordable formats, for example. The system (500) involves generating a menu (33) from stored data representative of a pre-formed menu containing a menu icon permitting User selection of data format conversion (90) of packetized data from a read-only data format to a different recordable data format. The system generates navigation parameters (43) that are compatible with the recordable data format and incorporates them in output data in response to User selection of the menu icon. In another feature, the pre-formed menu also contains an inactive menu icon that is activated by associating and linking an active command with the inactive menu icon.
Abstract:
An optical disk includes: a data region; and a management region. The data region stores: at least one audio object containing audio information; and at least one video object containing video information and audio information, wherein the management region stores a plurality of first management information units for managing progress of reproduction of the at least one audio object and a plurality of second management information units for managing progress of reproduction of the at least one video object, each of the plurality of first management information units including audio reproduction attributes and first path information indicating a reproduction order of the at least one audio object, each of the plurality of second management information units including video reproduction attributes and second path information indicating a reproduction order of the at least one video object, and wherein the management region further stores a first connection table containing first connection information and second connection information, the first connection information indicating a relationship of connection between the plurality of first management information units and the plurality of second management information units, and the second connection information indicating a relationship of connection among the plurality of first management information units.
