摘要： To prevent poaching of an Internet Protocol (IP) set top box (STB) asset or similar network computing device from one system operator to another, code executing in the IP STB not only authenticates downloaded software images using a public key provided in a serial-number assigned digital certificate, but also confirms that the serial number appears on a signed whitelist, or does not appear on a signed blacklist. The code executing in the STB further preferably enforces a rule that only the authority that signed the already-loaded whitelist/blacklist may replace it with a new list. Such a sticky whitelist/blacklist ensures that if the STB boots or resets in a new network, the existing authentication list will not be replaced by a list that is valid for a new or different network, and, as a result, that new software code images will not be authenticated.
摘要翻译：为了防止从一个系统运营商偷窃互联网协议（IP）机顶盒（STB）资产或类似网络计算设备到另一个系统运营商，在IP STB中执行的代码不仅使用串行端口中提供的公钥来验证下载的软件映像，号码分配的数字证书，但也确认序列号显示在签名的白名单上，或不显示在签名的黑名单上。在STB中执行的代码进一步优选地实施规则，只有签署已经加载的白名单/黑名单的权限可以用新的列表来替换它。这种粘性白名单/黑名单确保如果STB在新网络中启动或重置，则现有的身份验证列表将不会被对新的或不同的网络有效的列表所替代，因此，新的软件代码图像将不会被认证。

摘要： A system for processing sub-blocks of a macroblock of a video frame. In an example embodiment, the system includes a first module that is adapted to process each sub-block of the macroblock, wherein each sub-block is associated with a predetermined position in a first sequence. The processing of certain sub-blocks in the first sequence requires results of processing of one or more previously processed sub-blocks in the first sequence. A controller selectively enables the first module to process each sub-block of a second sequence that is altered from the first sequence so that the first module implements parallel or pipelined processing of certain sub-blocks of the macroblock. In a more specific embodiment each sub-block in the first sequence of sub-blocks is consecutively numbered 0-15 according to H.264 standards.
摘要翻译：用于处理视频帧的宏块的子块的系统
一种用于处理视频帧的宏块的子块的系统。在示例实施例中，该系统包括适于处理宏块的每个子块的第一模块，其中每个子块与第一序列中的预定位置相关联。第一序列中的某些子块的处理需要处理第一序列中的一个或多个先前处理的子块的结果。控制器选择性地使第一模块能够处理从第一序列改变的第二序列的每个子块，使得第一模块实现宏块的某些子块的并行或流水线处理。在更具体的实施例中，根据H.264标准，第一子块序列中的每个子块被连续编号为0-15。

摘要： Systems and methods are disclosed for adjusting bandwidth of streams carried on a subscriber loop. One exemplary method comprises the steps of: determining bandwidth in use on a subscriber loop; selecting, for adjustment, at least one of a plurality of TCP streams carried on the subscriber loop; and adjusting at least one flow control parameter of the selected TCP stream based on the bandwidth in use. An exemplary multimedia terminal adapter (MTA) comprises memory and a processor. The memory stores program code, and the code programs the processor to enable the MTA to: determine bandwidth in use on a subscriber loop; select, for adjustment, at least one of a plurality of TCP streams carried on the subscriber loop; and adjust at least one flow control parameter of the selected TCP stream based on the bandwidth in use.

摘要： Systems and methods are disclosed herein for requesting additional forward error correction, when needed, in a communication system. In one exemplary embodiment, among others, a method includes receiving a first set of data packets and a first amount of forward error correction (FEC) from an upstream transmitting device. The method also includes determining whether or not the first amount of FEC is sufficient to correct any detected errors with respect to the data packets. Then, an error indication is transmitted to the upstream transmitting device when the first amount of FEC is not sufficient to correct the detected errors.

摘要： Systems and methods for providing forward error correction are disclosed in the present disclosure. In one embodiment, among others, a method comprises transmitting a stream of data packets to a receiver and transmitting a first amount of forward error correction (FEC) to the receiver. The first amount of FEC is designed to restore a first number of dropped data packets. The method also includes receiving a message from the receiver that the first amount of FEC is not sufficient to restore a detected number of dropped data packets, and then transmitting additional FEC to restore the detected number of dropped data packets.
