    Abstract: A format programmable hardware packetizer (110) receives real-time raw input data (125) from a multimedia data source (103) via an analog to digital converter (105) and a data encoder (120) gated by encoder interrupts (127). The real-time raw input data is buffered in an internal byte collector of the packetizer (110). A main CPU interrupt (117) is issued to the main processor (130) when a packet boundary code is received. The packetizer (110) formats the data according to a desired format selected on line (115) for dump to the main memory (140) while providing a managed, much lower level of interrupts to the main processor (130) on the CPU interrupt line (117). A plurality of hardware packetizers (110) can be deployed according to alternative constructions for efficient real time packetizing in various selected formats.

    Abstract translation: 格式可编程硬件分组器(110)经由模数转换器(105)和由编码器中断(127)门控的数据编码器(120)从多媒体数据源(103)接收实时原始输入数据(125)。 实时原始输入数据被缓存在打包器(110)的内部字节收集器中。 当接收到分组边界码时,主CPU中断(117)被发送到主处理器(130)。 打包器(110)根据在线(115)上选择的期望格式将数据格式化,以转储到主存储器(140),同时向CPU中断线上的主处理器(130)提供被管理的,低得多的中断级别 (117)。 可以根据替代结构部署多个硬件打包器(110),以便以各种选择的格式进行有效的实时打包。
