摘要： A method for determining transfer rate comprising selecting a first transfer rate of a plurality of transfer rates, transmitting a message at the first transfer rate over a Consumer Electronics Control (CEC) line of a High Definition Multimedia Interface (HDMI) network, determining whether an acknowledgment to the message having been transmitted at the first transfer rate is received, storing, in the event the acknowledgment to the message having been transmitted at the first transfer rate is received, the first transfer rate and storing, in the event no acknowledgment is received, a default transfer rate of the plurality of transfer rates.

摘要： A Video On Demand (VOD) method consistent with certain embodiments involves processing content to be delivered in a VOD method by selecting first portions of the content for encryption under a selective encryption system and selecting second portions of the content to remain unencrypted. The first and second portions are stored until receiving a request for delivery of the content, the request being from a terminal having decryption capabilities associated with a first decryption method. The first portions are then bulk encrypted to produce encrypted first portions. The encrypted first portions are stored in a buffer. The second portions are queued for delivery to the terminal. A stream of selectively encrypted content is assembled from the encrypted first portions and the second portions. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
摘要翻译：与某些实施例一致的视频点播（VOD）方法涉及通过在选择性加密系统下选择用于加密的内容的第一部分来处理要在VOD方法中传送的内容，并且选择内容的第二部分保持未加密。存储第一和第二部分，直到接收到用于传送内容的请求，该请求来自具有与第一解密方法相关联的解密能力的终端。然后，第一部分被批量加密以产生加密的第一部分。加密的第一部分被存储在缓冲器中。第二部分排队等待送达终端。从加密的第一部分和第二部分组装有选择性加密内容的流。该摘要不被认为是限制性的，因为其他实施例可能偏离本摘要中描述的特征。

摘要： A method of processing content in a video on demand (VOD) system consistent with certain embodiments of the invention, wherein the content is identified by a first set of packet identifiers (PIDs), involves receiving content, the content having marked packets designating packets that are to be encrypted by a first encryption system by setting an encryption flag for all packets designated to be encrypted. Packets are selected in the content according to a selective encryption selection criterion to produce selected packets. The selected packets are duplicated to produce duplicate copies of the selected packets and these duplicate copies are identified using a second set of PIDs. The duplicate copies identified by the second set of PIDs are inserted into the content. All encryption flags in the content are cleared except for the selected packets having the first set of PIDs, so the encryption to follow is selective. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
摘要翻译：一种处理与本发明的某些实施例一致的视频点播（VOD）系统中的内容的方法，其中所述内容由第一组分组标识符（PID）标识，涉及接收内容，所述内容具有指定分组的标记分组，由第一加密系统通过为指定加密的所有分组设置加密标志来加密。根据选择性加密选择标准在内容中选择分组以产生所选择的分组。所选择的分组被复制以产生所选分组的重复副本，并且使用第二组PID识别这些副本。由第二组PID识别的副本被插入到内容中。除了具有第一组PID的所选数据包之外，内容中的所有加密标志都将被清除，因此要遵循的加密是有选择性的。该摘要不被认为是限制性的，因为其他实施例可能偏离本摘要中描述的特征。
