A device for printing a document, such as an HTML document, in which data to be incorporated into an output image can be described in the form of reference to an outside source, the device being capable of smooth printing a large document using a small memory. A document structural information manager creates document structural information which describes a structure of document elements, based on a result of analysis on an HTML document carried out by a document analyzer. During asynchronous downloading of substantial data of each document element, should work memory shortage occur, a memory manager unloads substantial data of a document element with a latter order at which to be incorporated into an output among those in the work memory, and saves the unloaded substantial data in an HDD. Thereafter, when data becomes no longer necessary as a result of being printed, the memory manager deletes the data from the work memory and reloads data saved in the HDD back to the work memory.

Image forming device and method

Disclosed is a digital broadcasting transmission/reception system having an improved reception performance and in a signal-processing method thereof. A digital broadcasting transmitter comprises a TS stream generator for inputting robust and normal packets having stuff bytes in predetermined positions and generating dual TS stream by inserting the robust packets between the normal packets; a randomizer for randomizing the dual TS stream; a stuff byte exchanger for replacing the stuff bytes of a randomized data streams from the randomizer to a predetermined known data; and an encoder for encoding a data streams to which the known data is inserted. Accordingly, the present invention detects the known data from a signal received from a reception side and uses the detected known data for synchronization and equalization, so that the digital broadcasting reception performance can be improved at poor multipath channels.

A digital cable broadcast receiver and a method for automatically processing caption data of various standards and types, is disclosed. The digital broadcast receiver includes: a demultiplexer for dividing a received broadcast stream into video data, audio data, supplementary information; a controller for determining whether caption data included in the video data is digital caption data or analog caption data on the basis of caption information included in the supplementary information, and outputting a control signal according to a result of the determining; a digital caption decoder for extracting and decoding digital caption data from the video data according to the control signal; and an analog caption decoder for extracting and decoding analog caption data from the video data according to the control signal.

Digital broadcast receiver and method for processing caption thereof

A method and system for providing reduced network bandwidth for picture in picture (PIP) video transmissions. The method includes receiving a request signal from a client display to scale a video signal, a server scaling an auxiliary video signal from which pictures presented in an auxiliary display of a client display are derived and the server encoding signals from which pictures presented in a main display and a auxiliary display of said client display are derived. Further, the method includes combining the signals from which pictures presented in the main display and the auxiliary display are derived and the server transmitting to the client display combined signals from which pictures presented in the main display and the auxiliary display are derived. The client then displays the main image and the PIP image.

Method and system for providing reduced bandwidth for picture in picture video transmissions

A method of distributed statistical multiplexing of video data. The method includes generating a plurality of blocks forming a pre-processed video media corresponding to an original video media, the plurality of blocks including, for one or more sub-portions of the original video media, a plurality of interchangeable blocks that represent the sub-portion. Optionally, at least some of the blocks are transmitted to at least one multiplexer and reconstructed by the at least one multiplexer, for a plurality of communication channels, from at least some of the transmitted blocks.

Distributed statistical multiplexing of multi-media

A digital television signal receiver (20) processes a digital television signal and auxiliary information contained in the digital television signal regardless of whether the auxiliary information is analog auxiliary information (36) or digital auxiliary information (34) and produces a television display signal (44) suitable for displaying the processed auxiliary information In the case of the auxiliary information being closed caption information, the digital television signal receiver extracts and processes digital closed captioning information according to standard EIA-708 or extracts and processes analog closed caption information according to standard EIA-608 The television signal processing receiver thus allows the user the option of selecting a fallback method of obtaining captioning for a digital program signal if the digital program signal does not include digital closed captioning Thus, if a digital television signal does not include digital closed caption information, the digital television signal receiver automatically processes any analog auxiliary information and provides a television signal having closed caption information suitable for display

Digital/analog closed caption display system in a television signal receiver

A TV system that uses a single pixmap across multiple video rasters having different raster sizes. In general, the TV system uses at least two sets of headers to select different portions of a single pixmap to be displayed based on different raster sizes. Specifically, each of the headers in a header set points to a pixel line to select number of pixels for that pixel line. The number of the headers in a header set determines the height of the pixmap and the pixel number selection by a set of headers determines the width of the pixmap. In response to different displaying modes, the TV system selectively invokes one of the two header sets to select different portions of the single pixmap. By doing so, a single pixmap can be used across multiple video rasters having different raster sizes.

Method and system for using single OSD pixmap across multiple video raster sizes by chaining OSD headers

A data format employing multiple different headers associated with corresponding OSD content facilitates the implementation of an efficient and flexible OSD management and control system. Each header contains a unique display characteristic or set of display characteristics for the interpretation and presentation of an associated OSD pixel map. In using this system, the presentation or modification of an OSD involves the selection of the header, associated with the OSD, having the desired display characteristics to be used in presenting or modifying the OSD.

Method and system for processing video incorporating multiple on screen display formats

Described is a TV system that uses a single pixmap across multiple video rasters having different raster sizes. In general, the TV system uses at least two headers to select different portions of a single pixmap to be displayed based on different raster sizes. Specifically, each of the two headers points to a single pixmap. In the TV system, the size of the central portion is fixed while the size of the sidepanel portion can be adjusted depending on the displaying mode. In response to different displaying modes, the TV system selectively invokes one of the two headers to select a respective portion to be displayed in the pixmap. By doing so, a single pixmap can be used across multiple video rasters having different raster sizes.

Method and system for using single OSD pixmap across multiple video raster sizes by using multiple headers

A TV system that uses a single pixmap (190) across multiple video rasters having different raster sizes. In general, the TV system uses at least two sets of headers (198, 200) to select different portions of a single pixmap (190) to be displayed based on different raster sizes. Specifically, each of the headers in a header set points to a pixel line to select number of pixels for that pixel line. The number of the headers in a header set determines the height of the pixmap (190) and the pixel number selection by a set of headers determines the width of the pixmap (190). In response to different displaying modes, the TV system selectively invokes one of the two header sets (198, 200) to select different portions of the single pixmap (190). By doing so, a single pixmap (190) can be used across multiple video rasters having different raster sizes.
