Abstract: A computer system including a write protection circuit and a write poster is disclosed. The write protection circuit provides page description information to the computer system for controlling various operations. Illegal write operations as defined by the page description information are prevented from reaching a system bus and external cache. Internal cache invalidate operations may also be performed transparently to system operation. The write poster accepts write operations in zero wait states and assembles them into fewer more efficient writes to memory. A unique method and apparatus for programming a descriptor random access memory (RAM) is also provided.

Abstract: A microcomputer includes a main memory system which is accessed, substantially independantly, by the CPU and a subsystem, for example a video display subsystem. The memory system comprises a base memory and an optical add on expansion memory. When only the base memory is installed, consecutive locations have consecutively numbered addresses, and both the CPU and subsystem access individual locations. When both memories are installed, one has even numbered addresses and the other odd numbered addresses. With both memories installed, the CPU still accesses individual locations, but the subsystem addresses even addresses to obtain, for each access, data from the even address and the next higher odd address, thereby accessing a location in both memories. Thus the memory bandwidth for the subsystem is effectively doubled when the expansion memory is installed.

Abstract translation: 微型计算机包括主存储系统，其主要由CPU和子系统（例如视频显示子系统）访问。 存储器系统包括基本存储器和光学附加扩展存储器。 当仅安装基本存储器时，连续的位置具有连续编号的地址，并且CPU和子系统访问各个位置。 当两个存储器都安装时，一个地址和其他奇数地址都是偶数地址。 在安装了两个存储器的情况下，CPU仍然访问各个位置，但是子系统寻址偶数地址，以便从每个访问获得来自偶数地址和下一个较高奇数地址的数据，从而访问两个存储器中的位置。 因此，当安装扩展内存时，子系统的内存带宽有效地加倍。

Abstract: In a data processing system including a dynamic RAM (14) and a programmable, prioritized direct memory access (DMA) controller (16) having a plurality of channels, the highest priority channel (0) is dedicated to a memory refresh operation. The system clock (P CLK) from the CPU (12) is applied to a divider counter (22) which produces a refresh clock (R CLK) having a period sufficient to generate the minimum number of refresh cycles within the minimum period required to refresh the RAM (14). The refresh clock (R CLK) is used to set a "D-type" latch (24) whose output, in turn, sets the highest priority DMA channel (0) request line (DREQ0), thereby initiating a memory refresh cycle. The latch (24) is cleared by the DMA acknowledge signal (DACK0) indicating the cycle is completed.

Abstract translation: 在包括具有多个信道的动态RAM（14）和可编程优先级直接存储器访问（DMA）控制器（16）的数据处理系统中，最高优先级信道（0）专用于存储器刷新操作。 来自CPU（12）的系统时钟（P CLK）被施加到分频器计数器（22），该分频器计数器产生具有足以在刷新所需的最小周期内产生最小数量的刷新周期的周期的刷新时钟（R CLK） RAM（14）。 刷新时钟（R CLK）用于设置“D型”锁存器（24），其输出依次设置最高优先级的DMA通道（0）请求线（DREQ0），从而启动存储器刷新周期。 锁存器（24）由DMA确认信号（DACK0）清零，表示循环完成。

Abstract: A central processing unit (10) loads a border register (36) with four color bits representing digital color signals to be used in determining the color of only the border area (40) surrounding the video area (42) of a cathode ray tube display screen (44). A BORDER CONTROL TIME signal is generated at the appropriate times in the horizontal and vertical scanning periods of the cathode ray tube to apply the digital color border signals (R, G, G, I) to a composite video signal generator (38) which generates the composite video signal for a TV set (14) or a TV monitor.

Abstract: Systems and methods may provide for communication between a plurality of client devices of a broadcast system. The communication may be, for example, a recommendation of a program that is communicated from one subscriber to another subscriber or subscribers via their client devices. The communication also may be a comment regarding a program, for example, recently viewed at the client device of the one subscriber. In general, the communication may be a message from one subscriber to another subscriber or subscribers. Further, the communication may be configured to perform a function on one or more other client devices. Such a function may include, but is not limited to, setting a timer to record a program, ordering or purchasing a program or service, cancelling an ordered/purchased program or service, setting or altering user preferences, controlling access to channels, etc.

Abstract: A method of generating and using indexing information for video content is presented. In the method, an index stream for a video stream is generated at a video content transmitter. The video stream includes video frames, and the index stream includes an index for each of at least some of the video frames within the video stream. The video stream and the index stream are transmitted from the video content transmitter to a video content receiver, which receives and stores the video and index streams. Further, at the video content receiver, the index stream is processed to locate the video frames within the video stream that are associated with at least some of the indexes of the index stream, and at least some of the located video frames of the video stream are presented to an output device under control of a user of the video content receiver.

Abstract: A method for providing a communication device access to a secure broadcast communication is presented. In the method, an encrypted message originating outside the communication device is received into an electronic component of the communication device. The encrypted message is then decrypted within the electronic component, resulting in a decrypted message. The decrypted message is then verified. In response to verifying the decrypted message, a disabled circuit of the electronic component is enabled to allow the communication device to access the secure broadcast communication.

Abstract: Content receivers may simultaneously record multiple instances of content for multiple programming channels based on content provider instructions. Systems and methods utilize the content receivers to perform memory jumping operations within files having the simultaneously recorded multiple instance of content stored therein. The memory jumping operation may jump locations within the file corresponding to a predetermined memory jumping operation timeframe, and in order to account for the variability in the recording bit rate and therefore the playing of the instance of content, the jump locations in the memory jumping operation may be dynamically adjusted based on recording bit rates.

Abstract: Content receivers may be configured to simultaneously record multiple instances of content for multiple programming channels based on content provider instructions. Systems and methods utilize the content receivers to dynamically adjust recording parameters to account for instances of content with a start time and/or end time that falls outside of predefined recording parameters. The dynamically adjusted recording parameters may adjust the number of channels recorded and/or instances of content recorded. The content receiver may compare programming information received at a processing unit with predefined recording parameters and may dynamically adjust the recording parameters based on the comparison. The content receiver may generate on screen display content to include information on the dynamically adjusted recording parameters and may transmit the on screen display content to a content display device for notifying the user of the dynamically adjusted recoding parameters.

Abstract: An electronic device may generate a matrix code that includes information for performing an interactive activity related to content, combine the matrix code with the content, and transmit the combination of the matrix code and the content to a display device. Subsequently, the displayed matrix code may be captured by a matrix code reader in order to initiate performance of the interactive activity. In some implementations, the content may be a sporting event and capture of the matrix code may initiate performance of an activity corresponding to a fantasy sporting event league associated with the sporting event. In various implementations, the matrix code reader's initiation of performance of the interactive activity related to the content may utilize one or more other electronic devices located in a user location.
