Methods of Palette Based Prediction for Non-444 Color Format in Video and Image Coding
A method of video coding using palette coding mode for color video in a non-444 color format is disclosed. The non-444 video data can be converted to the 444 format so that the palette designed for the 444 format can be used for the non-444 video data. For the 4:2:0 color format, each chroma sample collocated with corresponding quad luma samples is padded with three chroma samples to form converted quad chroma samples. For the 4:2:0 color format, if a current pixel does not belong to the color palette, one or more escape values are signaled for the current pixel and the escape value associated with the chroma sample of the current pixel for each color component is not signaled for three of the quad chroma sample locations collocated with corresponding quad luma samples.
Device and control method for the device
An electronic device, including a display; and a controller capable of displaying, via the display, an image being reproduced, a letterbox and subtitles positioned at the letterbox; receiving a control signal for enlarging a display size of the image; controlling the display to enlarge the image in response to the control signal, further the subtitles is positioned at the enlarged image.
Processing segments of closed-caption text using external sources
Particular embodiments provide supplemental content that may be related to video content that a user is watching. A segment of closed-caption text from closed-captions for the video content is determined. A first set of information from the segment of closed-caption text, such as terms may be extracted. Particular embodiments use an external source that can be determined from a set of external sources. To determine the supplemental content, particular embodiments may extract a second set of information from the external source. Because the external source may be more robust and include more text than the segment of closed-caption text, the second set of information may include terms that better represent the segment of closed-caption text. Particular embodiments thus use the second set of information to determine supplemental content for the video content, and can provide the supplemental content to a user watching the video content.
ADVANCED PICTURE QUALITY ORIENTED RATE CONTROL FOR LOW-LATENCY STREAMING APPLICATIONS
An advanced constant quality rate control algorithm with new features and enhancements. can be applicable to different kinds of video scenes, in addition to static or less motion scenes. Statistical data is calculated at the beginning of encoding for each line of sections of a frame. Based on the statistical data, which case of a plurality of cases to be executed is determined and maximum and minimum QP values are determined according to the determined case. Actual maximum and minimum QP of the current line using is maintained using the maximum and minimum QP and a final QP value is determined for all sections in each line. A lambda value for encoding is determined from the final QP. At the end of encoding the picture, the number of frames encoded using constant quality is counted, the maximum and minimum QP and VBV fullness for each line is updated.
List searching method and portable device using the same
A method and a portable device controls output of a display unit to display information accurately and clearly regardless of a background image. Disclosed is an arrangement for calculating a difference between an arbitrary expression value of an arbitrary screen configuration element to be displayed on a given area of the background image and an actual expression value of the given area of the background image. Each expression value includes at least one of a color and lightness. The arrangement automatically selects the expression value of the screen configuration element based on the calculation result. The screen configuration element is displayed at the given area of the background image based on the selected arbitrary expression value.
Adaptive impedance matching interface
A device is described. The device includes a data interface connector, an application processor, and interface circuitry. The application processor can receive signals via an antenna. The interface circuitry can be coupled between the application processor and the data interface connector. The data interface circuitry can determine a change in a signal property of one of the signals, the change being caused by an impedance mismatch between the data interface connector and a media consumption device. The data interface circuitry can also send the application processor a signal property setting corresponding with the change. The application processor can adjust the signal property of a subsequent one of the signals, in response to the signal property setting from the interface circuitry, to obtain an adjusted signal. The application processor can also send the adjusted signal to the media consumption device.
Subtitle display method and subtitle display device
Embodiments of the present disclosure provide a subtitle display method and a subtitle display device, and relate to the field of communications technologies. Category content is presented to a user in an interactive graphic manner, so that the user can select corresponding category content according to the user's preference, and subtitles corresponding to the category content are displayed. The method includes receiving a subtitle file, and parsing a category label of the subtitle file, where the category label includes category content; presenting, on a display device in an interactive graphic manner, the category content for a user to perform selection; and receiving a result of selecting one or more pieces of the category content by the user, and displaying, according to the selection result, subtitles corresponding to the selected category content, therefore classified display of subtitles is implemented.
Metadata transfer in audio video systems
Aspects relate to transmission of metadata from a source to a sink device, and optionally through one or more intermediaries. A source device encodes metadata into what would have been a blanking area of a field to be transmitted, according to a current video format. The source device encodes a timing for an active video data signal that is modified from a timing that would be used only for transmission of video data at a current resolution. A separate indicator from the source, or a negotiation between source and sink allows the sink to determine what part of the data indicated as being active video data is metadata, and to use that metadata for controlling aspects of the video display, and to use other parts of the received video data as video data for display. A sink can signal supported capabilities to a source.
