20140201636 | METHODS AND APPARATUS FOR RENDERING USER INTERFACES AND DISPLAY INFORMATION ON REMOTE CLIENT DEVICES - A user interface is implemented on a client device remote from a host device. The host device operates an application program that implements a user interface, such as an electronic programming guide or a guide for a personal video recorder, that permits a user to control at least one target device. The host device transfers to the client device an identification of at least one scene. In general, a scene defines an abstract layout for at least one screen display of the user interface. The client device generates at least one screen display for the scene based on its interpretation of the scene. The client device then displays the screen as an implementation of the user interface. Thereafter, a user initiates, using the client device, an operation to control the target device. In response, the target device performs the operation. The host device may also display information at a client device For example, the host device may transmit information about a media currently playing at the client device. | 07-17-2014 |

20120195572 | METHOD AND APPARATUS FOR REPRODUCING COMPRESSED MEDIA CONTENT - A data file reproduction system has a data file supplying apparatus that extracts video data and audio data from a received data file, compresses the extracted video and audio data and produces a compressed data file containing the compressed audio and video data together with meta or navigation data determined from the data file for enabling navigation of the original data file. The compressed data file is then copy-protected. Upon request, the copy-protected compressed data file is communicated to a reproduction apparatus which decompresses the compressed audio and video data of the received copy-protected compressed data file, encodes the decompressed audio and video data and produces a copy-protected reconstituted data file containing the encoded audio and video data together with the meta or navigation data determined from the copy-protected compressed data file, so enabling navigation of the copy-protected reconstituted data file, the same as the original data file. | 08-02-2012 |

20120131218 | METHODS AND APPARATUS FOR INTEGRATING DISPARATE MEDIA FORMATS IN A NETWORKED MEDIA SYSTEM - A media system includes at least a source media device and a playback media device coupled through a network. The source media device presents media to the network. The media comprises at least one digital content file with a first format. A transcoder, also coupled to the network, converts the first file format of the digital content file to a second format. The playback device receives the digital content file, formatted in the second format, over the network, and processes the digital content file in the second format to generate processed signals. The processed signals drive the playback device to play the digital content file. In another embodiment, the transcoder operates in conjunction with one or more media servers. For this embodiment, media, stored on the media, stored on the media servers, is converted to one or more different file formats. | 05-24-2012 |
20120110139 | APPLICATIONS REGISTRY FOR A TELEVISION ENVIRONMENT - An applications registry provides a repository of television-based applications. The registry stores information about television-based applications registered, and allows users to view information regarding the registered television-based applications through one or more portals. The information includes a general description of the television-based applications, a description of an entitlement model for the television-based applications, and downloading information to permit a user to download the application to the home media system. The user accesses the registry, to view information about the television-based application, through a home media system. The home media system, which includes a television, accesses the portal over a network, such as the Internet. | 05-03-2012 |
20120033946 | COPY PROTECTION OF OPTICAL DISCS - Generally the more effective is the copy protection provided on an optical disc, such as a DVD, the greater is the likelihood that the copy protection will adversely interfere with legitimate uses of the optical disc. It is therefore proposed to include at least one region of subversive data within the content in the data area of an optical disc, and then to prevent access to each such region of subversive data during normal playback of the disc. For a DVD, the subversive data may be incorporated within video objects and/or may be in gaps between files in the DVD_Video zone. It is arranged that there are no navigable paths to the regions of subversive data. | 02-09-2012 |

20110264923 | SELF-PROTECTING DIGITAL CONTENT - Technologies are disclosed to transfer responsibility and control over security from player makers to content authors by enabling integration of security logic and content. An exemplary optical disc carries an encrypted digital video title combined with data processing operations that implement the title's security policies and decryption processes. Player devices include a processing environment (e.g., a real-time virtual machine), which plays content by interpreting its processing operations. Players also provide procedure calls to enable content code to load data from media, perform network communications, determine playback environment configurations, access secure nonvolatile storage, submit data to CODECs for output, and/or perform cryptographic operations. Content can insert forensic watermarks in decoded output for tracing pirate copies. If pirates compromise a player or title, future content can be mastered with security features that, for example, block the attack, revoke pirated media, or use native code to correct player vulnerabilities. | 10-27-2011 |

One embodiment includes an apparatus and method for receiving a content signal via a WiFi communications channel, the content signal including a control signal; and using a modifying circuit coupled with the WiFi communications channel to generate an analog copy protection signal based on the control signal, the control signal causing the modifying circuit to add or delete the analog copy protection signal to or from the content signal. | 05-05-2011 |
20100246882 | SCALING INDEPENDENT TECHNIQUE FOR WATERMARKING IMAGES WITH RECORDER SHUT-OFF - A robust technique to prevent illicit copying of video information notwithstanding the use of image scaling. A watermark is embedded into the video signal (e.g., DVD's content or other video sources) at different scales (i.e., sizes). The watermark is maintained at each scale for a predetermined time duration that is sufficient to allow the detector circuit in a DVD-recorder, DVHS recorder, DVCR, or any other digital format recorder to detect, extract, and process information contained in the watermark. At the end of the predetermined time duration, the watermark is changed to a different scale preferably on a pseudo-random basis to ensure that each one of all the scales in a predetermined scaling range is achieved a predetermined number of times. Thereby the recorder shuts off a number of times during play of the content, each time the detector circuit senses the watermark. | 09-30-2010 |
