A cable organization unit includes a housing. A tray is attached to the housing by at least one slide, and is movable between a first position and a second position relative to the housing. A hood is removably secured to the tray. A user may remove the hood from the tray to access adapters attached to a bulkhead on the tray. The tray may include a latch for securing the tray to the housing in the first position, and the hood may be removed from the tray while the tray is in the first or second positions. A retainer is optionally attached to the housing. The retainer includes an adjustable opening which may be reduced in size such that edges of the opening frictionally engage and hold a jacket of a cable passing therethrough.

A method of embedding information in digital content representing media streams. The method includes (1) selecting a set of locations within that digital content representing 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.

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.

A method, apparatus, and memory storing instruction that generate one or more playlists. In one aspect, a playlist is generated by calculating coincidences distances between pairs of items in a group and generating a playlist of plural of the items in the group responsive to the coincidence distances. In another aspect, two related playlists are generated, for example by using a same coincidence criteria for the playlists or by using mutual similarity criteria between the playlists.

A home theater system includes construction, presentation, and commerce in, songs. Presentation includes at least one of: metadata about songs or sounds, a function capable of transitioning from one song to a next song, and user preferences; and can determine in what manner to transition from one song to a next song. Construction of songs includes either factors above, or at least one of: a function or a user extension capable of selecting a next song, and an element capable of determining whether the song is perceptually random. A user interface is capable of searching playlists and selecting them for presentation, representing each playlist with a substantially unique pictorial representation, distinguishing in presentation between those playlists licensed to the user and those that are not, and capable of substantially immediate purchase of playlist licenses either individually or in bulk and either automatically or with minimal intervention.

摘要:
A cassette for a plurality of components for a cam drive and timing system for an engine the components comprising a guide and a tensioner attached to a tensioner bracket, a chain, a camshaft sprocket, and a crankshaft sprocket. The cassette is comprised of a body defining clearance holes and shoulder guides for placement of the camshaft sprocket, the crankshaft sprocket and the chain; and at least one fastener engaging the body of the cassette to the tensioner bracket, such that when the body of the cassette is engaged to the tensioner, the chain runs around the camshaft sprocket and the crankshaft sprocket, and the guide and the tensioner are positioned relating to the chain in the same relationship and position as the components are installed on the engine, all components are pivotally placed for installation on the engine.
摘要:
The invention provides a method and system capable of interacting with a server device, with the effect of being able to conveniently present, in a distinct way, those objects not already owned by the user. Multiple views of collections of objects are presented to the user. The portion of the view that reflects objects not owned by the user is degraded in such a way that the user is able to quickly surmise the objects not yet owned. The view may include fractionally degraded and completely degraded views such that fractionally degraded views indicate another aspect of an object. For example, an object may be local to the user but the user may not have licensed the use the object, or the degraded view may indicate that the object is not yet available but it will be available shortly. Users can decide whether to take action based on the presentation.
摘要:
The invention provides a method of recovering from de-synchronization attacks includes registering original and altered digital content using nonlinear transformations to iteratively attempt to provide better-approximated registration. Approximation occurs at more than one level of granularity, by selecting among a greater number of possible transformation functions at each step. Transformations and comparisons might be conducted directly on pixel values, on coefficients for a set of basis wavelets, or on some transformation of the original and altered digital content. A human operator might assist this process, such as by suggesting transformations or providing evaluation of the degree of registration. Upon resynchronization, embedded identifying information in the original digital content is recovered.
