摘要： A color interpolation circuit allows information uniquely identifying one of six colors to be stored by using only two binary bits of memory storage, and allows information uniquely identifying one of 120 colors to be stored by using only four binary bits of memory storage. This is accomplished by storing only the foreground, edge, and background colors (i.e., herein referred to as "independent" colors), and an "interpolate operator" code, and by providing circuitry to properly interpret and process the interpolate operator code to generate "intermediate colors". This permits a 33% reduction of memory size and reduces the "fetch speed" requirements of associated on-screen display (OSD) scan converter circuitry.
摘要翻译：颜色插值电路允许通过仅使用存储器存储器的两个二进制位来唯一地识别六种颜色中的一种的信息，并且通过仅使用四个二进制位的存储器来允许唯一地识别120种颜色之一的信息。这通过仅存储前景，边缘和背景颜色（即，这里称为“独立”颜色）和“内插运算符”代码，并且通过提供电路来适当地解释和处理内插操作码以产生 “中间色”。这允许存储器大小减少33％，并降低相关屏幕显示（OSD）扫描转换器电路的“提取速度”要求。

摘要： A method of processing a packetized datastream that includes program information and ancillary information used to acquire desired program information packets. The method includes the steps of identifying a first data unit that includes channel information and identifying a plurality of second data units included with the first data unit. The plurality of second data units are of a fixed length, and thus, separated in the packetized datastream by a multiple of a fixed offset. The method further includes the step of acquiring desired second data units using the fixed offset and subsequently determining the available services associated with a program and acquiring the desired program packets from the datastream.

摘要： Apparatus in a receiver, for processing transmitted entitlement control information, includes a packet transport processor for selecting signal packets having payloads containing a conditional access payload header and a remaining payload of entitlement data. Respective payload headers include groups of bytes which are coded in a manner to allow or disallow the respective receiver from processing the entitlement data. A conditional access filter preprogrammed with a subscriber specific conditional access codeword examines respective byte groupings of the conditional access header for a match with the subscriber specific conditional access codeword. Only if a match occurs is the processor permitted to process the entitlement data. The entitlement data is thereafter utilized to generate decryption keys for descrambling portions of the transmitted signal.

摘要： A smart card that includes a descrambler for descrambling entitlement information and data provides improved access control by controlling the manner in which the entitlement information portion of the data stream is passed through the smart card. Entitlement data that is descrambled and used in the smart card for functions such as key generation is reinserted in scrambled form in the high speed output data signal from the smart card. A variable delay device is included in the smart card for controlling when scrambled entitlement data is reinserted into the data stream. Varying the delay permits establishing a desired timing relationship between the reinserted data and other data in the data stream that is output from the smart card. For example, scrambled entitlement data in the output data stream can be made to exhibit substantially the same timing relationship to other data that exists in the input data stream.

摘要： A system processes a video signal that includes a plurality of signal components representing respective ones of a plurality of video programs such as various pay-TV programs. Each of the signal components is processed, e.g., descrambling a pay-TV program, by one of a plurality of series connected high speed signal processing integrated circuit (IC) cards, or "smart" cards. An output signal from the last smart card in the series connection includes a plurality of processed signal components. The plurality of processed signal components are processed further to produce a signal suitable for producing a displayed image that includes multiple image portions, such as a picture-in-picture (PIP) or picture-outside-picture (POP) image in a television system. Each portion of the image is produced in response to one of the processed signal components.
