Abstract: A set top box is provided that includes a receiver/tuner for receiving programming content over a broadband communications network, an encrypter/decrypter for encrypting and decrypting the programming content, and a secure memory configured to store at least a first cryptography key to be used by the encrypter/decrypter to encrypt and decrypt the programming content. The set top box also includes a digital storage medium for storing encrypted programming content, a multimedia processor operationally associated with the receiver/tuner, the decrypter, and the digital storage medium, and a user interface operationally associated with the multimedia processor.

Abstract: A set top box is provided that includes a receiver/tuner for receiving programming content over a broadband communications network, a secure memory configured to store at least a first cryptography key to be used to encrypt and decrypt the programming content, and a digital storage medium for storing encrypted programming content. The set top box also includes a multimedia processor operationally associated with the receiver/tuner, the secure memory, and the digital storage medium. The multimedia processor is configured to: encrypt programming content using the first cryptography key stored in the secure memory and uniquely associated with the set top box; store the encrypted content on the digital storage medium; encrypt the first cryptography key using an asymmetric public encryption key to form an encrypted first cryptography key; and store the encrypted first cryptography key on the digital storage medium.

Abstract: A method (100; 200) and apparatus (230) for controlling a display of video being output from a set-top box determines (102) if a user selected channel contains programming having a first aspect ratio and stretches (106) automatically video from the user selected channel having the first aspect ratio, if the user selected channel contains programming having the first aspect ratio, to fill a frame having a second aspect ratio that is different than the first aspect ratio using a predetermined stretching function. This determining and stretching is initiated automatically upon tuning (101) to a user-selected channel.

Abstract: A technique is described that allows a viewer to eliminate a fixed information band portion of a television image (e.g., a scrolling news “crawl or fixed advertising band) from a television display by “stretching” the main program portion to fill the screen, effectively pushing the undesired crawl or advertising band off of the display. This eliminates a feature of many television broadcasts that many viewers find distracting and/or annoying, and helps to prevent phosphor burn on phosphor-based display screens.

Abstract: A method for selectively passing closed caption data from a source device to a display device includes receiving a data signal including un-rendered closed caption data and video data in the source device, separating the video data from the un-rendered closed caption data, determining closed caption processing capabilities of the display device, and if the display device is configured to process un-rendered closed caption data, transmitting the un-rendered closed caption data to the display device.
