摘要： A processing apparatus for processing multiple video programs from one or more transport streams. The processing apparatus has a transport processing circuit that includes multiple transport processor units. The transport processor units utilize a common transport processor memory unit having demux context entries containing processing and hardware state information for packet types. Each transport processor unit includes a transport interface for identifying data packets to be acquired from the transport stream, a demultiplexing processor for processing the acquired data packets, and a demultiplexing DMA unit for memory handling operations of the processed data packets. Index chaining allows the transport processor units to access information from the transport processor memory unit. The method uses indices to access demux context entries from the transport processor memory unit. Related DMA indices are used to access memory handling information from the transport processor memory unit.

摘要： A method and apparatus for managing error/status information generated in the demultiplexing, processing, and handling of data packets from a video transport stream. Error/status information is organized into control fields of error/status packets. The error/status packets are sent to dedicated error/status buffers of bulk system memory where they can be accessed by a system processor during the reconfiguration and decoding of video programming.

摘要： A digital receiver contains a local video clock that controls the video presentation speed and a local audio clock that controls the audio presentation speed separately and independently of the video presentation speed. To control the video presentation speed, a comparator compares a program clock reference in a video packet with a local time. A video clock controller then speeds up or slows down the video clock as needed to be back on schedule. To control the audio presentation speed, a comparator compares a program clock reference in an audio packet with the local time. An audio clock controller then speeds up or slows down the audio clock as needed to be back on schedule.

摘要： An apparatus and method for taking data that is presented on a NUBUS in NUBUS format and writing it into a video memory in chunky planar format, is described. The present invention is also useful for performing RGB reads wherein video data is read from the video memory in chunky planar format and is translated into NUBUS format for transmission across the NUBUS. The apparatus comprises a data format translator which is coupled to the NUBUS for translating the RGB data from NUBUS format to chunky planar format. The translated RGB data in chunky planar format is compressed and rearranged as compared to the NUBUS format--resulting in a more efficient utilization of video memory space. An address generator is also coupled to the video memory for calculating the address location in the video memory where the translated RGB data is to be written. The address location is derived from the NUBUS address according to the formula N.sub.start =(3*NAD/4) where N.sub.start is the start address in video memory and NAD represents the NUBUS address from which the RGB data to be translated is obtained.
摘要翻译：描述了以NUBUS格式呈现在NUBUS上的数据并将其以块状平面格式写入视频存储器的装置和方法。本发明对于执行RGB读取也是有用的，其中以小块平面格式从视频存储器中读取视频数据，并且被翻译成NUBUS格式用于在NUBUS上传输。该装置包括数据格式转换器，该数据格式转换器耦合到NUBUS，用于将RGB数据从NUBUS格式转换成块状平面格式。与NUBUS格式相比，以粗大的平面格式转换的RGB数据被压缩和重排，从而更有效地利用视频存储器空间。地址发生器还耦合到视频存储器，用于计算视频存储器中要转换的RGB数据要写入的地址位置。地址位置根据公式Nstart =（3 * NAD / 4）从NUBUS地址导出，其中Nstart是视频存储器中的起始地址，NAD表示从中获得要转换的RGB数据的NUBUS地址。
