A main stream contains successive content elements of video and/or audio information that encode video and/or audio information at a first data rate. A computation circuit (144) computes main fingerprints from the successive content elements. A reference stream is received having a second data rate lower than the first data rate. The reference stream defines a sequence of the reference fingerprints. A comparator unit (144) compares the main fingerprints with the reference fingerprints. The main stream is monitored for the presence of inserted content elements between original content elements, where the original content elements have main fingerprints that match successive reference fingerprints and the inserted content elements have main fingerprints that do not match reference fingerprints. Rendering of inserted content elements to be skipped. In an embodiment when more than one content element matches only one is rendered. In another embodiment matching is used to control zapping to or from the main stream. In another embodiment matching is used to control linking of separately received mark-up information such as subtitles to points in the main stream.

In one embodiment, a method of generating an electronic program guide for a user of an entertainment system is disclosed. The method includes retrieving, by a user computer in communication with the entertainment system, preference criteria corresponding to one or more user preferences describing payment requirements. The user computer receives a plurality of content listings, each content listing comprising a content title, an indication of a content source, and a payment requirement, and a search query including a content title. The user computer also identifies a subset of the plurality of content listings based on content title and the search query, and ranks each content listing in the subset based on a comparison of the preference criteria and the payment requirement of each content listing in the subset. A content entry in the electronic program guide is created comprising each content listing in the subset in ranked order.

A method and apparatus for secure transfer and playback of multimedia content enables the secure transfer of multimedia content from a digital video recorder (DVR) to a personal computer (PC) and further to a handheld device. A DVR determines which devices on a Local Area Network (LAN) are authorized to share and/or retrieve content from the DVR. The DVR receives a connection request from a PC on the LAN, authorizes the connection request and establishes a secure connection between the DVR and the PC. Once the secure connection is established, the DVR receives a request for multimedia content from the PC, prepares the multimedia content for transfer and transfers the multimedia content to the PC.

A robust, computationally-efficient and secure system is described for streaming content from a server to a client device via the Internet or another digital network. Various aspects relate to automated processes, systems and devices for securing a media stream with efficient yet effective digital cryptography. In particular, content may be transmitted in transport stream (TS) format in which all packets are encrypted (e.g., using a cipher block chain), in which control packets are exempted from encryption (e.g., using an electronic codebook), or in any other manner.

A method and apparatus for performing an integrated search is provided. An interface is provided that allows users to search and select any data related to a searchable term. Searchable terms may comprise titles of content, actors, and tags. Upon receiving results from the initial search, the user progresses through the initial search by selecting a result from the initial search and conducting a further search of that selection. The search may progress through many layers of searching in order to find information useful to the user and the user may perform actions based upon results of the search. The search implements a display with two columns, the first column displaying selectable data, and the second column displaying results to the selected data. The search is further customizable based upon a privacy level selected by the user.

Recording equipment, as well as methods of using the recording equipment, methods of experiencing recorded episodes, and methods of distributing the recorded episodes.

A system and method enabling the storage and retrieval of packetized digital content data in a manner which minimizes the detrimental effects of dropped data packets. The dropped packets, encoded in accordance with a first profile, are detected and corresponding data packets obtained from an alternate profile of the digital content are substituted for the missing packets when the data is retrieved. Upon retrieval, the stored data packets are decoded in accordance with protocols associated with the particular profile from which each stored packet was obtained.

In some implementations, a first device can record a display screen of a second device remotely. For example, the first device (e.g., a remote computing device) can receive information identifying other computing devices on a network. The first device can receive a selection of one of the other computing devices (e.g., the second device) and send a message to the second device to initiate a recording of the display screen of the second device. In response to receiving the message, the second device can record video frames of images presented on the display of the second device. The second device can send the video frames to the first device for display and/or storage. While recording the images presented on the display screen, the second device can present indicia on the display screen of the second device indicating that a screen recording is in progress.
