摘要： This disclosure relates to a station for a data transmission network which is adapted to operate in a cyclic mode for contending for access to the network channel along with other stations of the network. The three states of the cycle are the idle state, the packet-being-transmitted state and the acknowlegement period state. Each station will not begin transmission until it determines that the channel is in an idle state. Once the station has determined that the channel is idle, it will then delay for a period of time that is randomly chosen and, if the channel is still idle, will then begin transmission. In this way, contention conflicts between stations is minimized without unduly restricting communication between stations. Following transmission, the channel will again be quiescent a short period of time before the acknowledgement signal is transmitted from the receiver. Each packet of data to be transmitted is of a fixed length so as to provide for synchronization between various stations contending for access to the channel.
摘要翻译：本公开涉及一种用于数据传输网络的站，其适于以循环模式操作，用于与网络的其他站一起竞争访问网络信道。循环的三个状态是空闲状态，分组传输状态和确认周期状态。在确定通道处于空闲状态之前，每个站将不会开始传输。一旦站已经确定信道是空闲的，它将随后延迟一段随机选择的时间，并且如果信道仍然空闲，则将开始传输。以这种方式，站点之间的争用冲突被最小化，而不会不适当地限制站点之间的通信。在发送之后，在从接收机发送确认信号之前，该信道将在短时间内再次静止。要发送的每个数据包是固定长度的，以便提供竞争接入信道的各个站之间的同步。

摘要： This disclosure relates to a system and method for the synchronization of variable-length messages being transmitted between stations of a local area contention network where the messages are made up of a variable number of fixed-length packets. This system is adapted for automatic address assignment of different stations of the network so that the network may be expanded or contracted by adding stations and removing stations respectively. In this manner, a very reliable network is provided in that the failure of any particular station does not interfere with the functioning of the other stations in the network or the network itself. In addition, the system includes provision for associating various server stations with a given procedure so that a client station may broadcast a request for a procedure and corresponding server stations will send the response to the client station containing the network identification of the server station. If two or more stations contain the particular procedure called for, the first one to respond to the client station is selected.

摘要： Selection and presentation of media streams, in which presentation is not limited by order imposed by the digital content representative of those media streams, in response to bookmarks and watchpoints settable and usable by a user. Bookmarks reference a location within the media stream, not necessarily pre-selected and possibly dynamically selected, in which a presentation can be started or restarted therefrom. Watchpoints reference a location within the media stream, or a presentation state for the media stream, in which an action can be triggered thereby. Bookmarks and watchpoints provide a general technique for presenting selections from media streams in response to metadata.

摘要： A method of embedding information in digital content representing media streams. The method includes (1) selecting a set of locations within that digital content reprensenting the media stream to embed information, (2) selecting a set of possible alterations to make at those locations, and (3) making a subset of the possible alterations. The set of locations and possible alterations is herein sometimes called a “watermark.” The subset of actual alterations that are made is herein sometimes called a “fingerprint.” The method determines a set of locations at which there are alternative versions of digital content representing the same media stream, such as one being the original and one being an alternative version of the same digital content, herein sometimes called the “original movie” and the “alt-movie,” or herein sometimes called the “original block” and the “alt-block” for a particular block in the digital content representing the media stream.

摘要： The invention provides a method and system for operating multiple communicating caches. Between caches, unnecessary transmission of repeated information is substantially reduced. Each cache maintains information to improve the collective operation of the system of multiple communicating caches. This can include information about the likely contents of each other cache, or about the behavior of client devices or server devices coupled to other caches in the system. Pairs of communicating caches substantially compress transmitted information. This includes both reliable compression, in which the receiving cache can reliably identify the compressed information in response to the message, and unreliable compression, in which the receiving cache will sometimes be unable to identify the compressed information. A first cache refrains from unnecessarily transmitting the same information to a second cache when each already has a copy. This includes both maintaining a record at a first cache of information likely to be stored at a second cache, and transmitting a relatively short identifier for that information in place of the information itself. A set of caches are disposed in a directed graph structure, with a set of root caches disposed for coupling to server devices and a set of leaf caches disposed for coupling to client devices. Both root caches and leaf caches maintain non-cacheable objects beyond their initial use, along with digests of the non-cacheable objects. When a server device returns identical information to a root cache, root caches can transmit only associated digests to leaf caches, avoiding re-transmitting the entire non-cacheable object.
摘要翻译：本发明提供了一种用于操作多个通信高速缓存的方法和系统。在高速缓存之间，重复信息的不必要的传输显着减少。每个缓存维护信息以改善多个通信高速缓存系统的集合操作。这可以包括关于每个其他高速缓存的可能内容的信息，或关于耦合到系统中其他高速缓存的客户端设备或服务器设备的行为。成对的通信缓存基本上压缩了传输的信息。这包括可靠的压缩，其中接收缓存可以可靠地识别响应于消息的压缩信息，以及不可靠的压缩，其中接收缓存有时将不能识别压缩信息。当每个已经具有副本时，第一高速缓存避免不必要地将相同的信息发送到第二缓存。这包括在可能存储在第二高速缓存处的信息的第一高速缓存上保持记录，以及代替信息本身来发送该信息的相对较短的标识符。一组缓存被布置在有向图结构中，一组根高速缓存被设置用于耦合到服务器设备和一组叶高速缓存，其被设置用于耦合到客户端设备。根高速缓存和叶高速缓存都保留超过其初始使用的非可缓存对象，以及不可缓存对象的摘要。当服务器设备向根高速缓存返回相同的信息时，根高速缓存可以仅将关联的摘要传输到叶高速缓存，避免重新发送整个不可缓存的对象。

摘要： Secure presentation of media streams includes encoding the media streams into digital content, encrypting a portion of that digital content, the portion being required for presentation, in which the encrypted version is substantially unchanged in formatting parameters from the clear version of the digital content. Selecting those portions for encryption so there is no change in distribution of the media stream: packetization of the digital data, or synchronization of audio with video portions of the media stream. When encoding the media stream into MPEG-2, refraining from encrypting information by which the video block data is described, packet formatting information, and encrypting the video block data using a block-substitution cipher. A block-substitution cipher can be used to encrypt each sequence of 16 bytes of video data in each packet, possibly leaving as many as 15 bytes of video data in each packet in the clear.
