TH17585A - "Local stream set guide for assembling the passed dataset" - Google Patents

Abstract

Digital TV signal processing system In this case, a unique data set bar (PAF) code word is inserted into the MPEG coding bit stream to indicate the presence of a group of images (GOP), while the PAF precedes the initiation code word. The image in the I frame, which is the beginning of the GOP, the dataset under that structure when the PAF that appears is terminated because the GOP segment is initiated at the boundary of the set. Such termination will result in The abbreviated dataset contains fewer than a predetermined number of code words to make the data set. Such complete The last word of each data set is assigned to facilitate further Combining the sequence of the dataset with the appropriate header signal. Incomplete data sets will be added. Full of zero words (Zero bit) to complete that dataset with a given number of words.

Claims (5)

1. a code word stream processing device that represents an image that contains a path for the generation in which the code word stream contains. Order of image data groups Input way That responds to the said stream to create a bar display (PAF) before the emergence of a group of images representing the emergence of such groups of images. Coding pathways That responds to the said stream to create Code words to be in the form of datasets. The way of processing the code will also respond to the bar. Above to stop that dataset. Where the truncated dataset consists of a smaller number. Predetermined potential word and output path That responds to that dataset to create the dataset. Transmitted through which the data will be set up 2. Equipment according to claim 1, which the data stream It has a format similar to MPEG, which is a group of images. There will be image data on frame I, which is encoded within the frame. The code word that starts the image is combined with the information in the I frame. The bar appears before the code word that starts the image. 3. Device according to claim 1, and it also includes a means to fill such abbreviated dataset with zero term inactive to maintain the required number of words for the dataset. 4. Equipment according to claim 1 and which also contains a path for establishing the last word indicator signal. To represent the value The last item in the dataset 5. Equipment according to claim 4 and which also includes a method for filling in the aforementioned shortened data sets with the words It's a non-working zero. To maintain the number of words defined for the data set
