摘要:
A media device may be configured for receiving data from one or more satellites. The media device may include one or more processors and one or more storage devices. A first tuner of a media device may tune to a first data stream that came from a first satellite transponder. A second tuner of the media device may tune to a second data stream that came from a second satellite transponder. The first data stream and the second data stream may be derived from source data based at least in part on a data distribution scheme. The data distribution scheme may include distributing at least portions of the source data with the first data stream and the second data stream. The first data stream and/or the second data stream may be processed to store and/or output for presentation content.
摘要:
Systems and methods for implementing a Transport I/O system are described. Network encrypted content may be received by a device. The device may provide the network encrypted content to a secure processor, such as, for example, a smart card. The secure processor obtains a network control word that may be used to decrypt the network encrypted content. The secure processor may decrypt the network encrypted content to produce clear content. In embodiments, the secure processor may then use a local control word to generate locally encrypted content specific to the device. The device may then receive the locally encrypted content from the secure processor and proceed to decrypt the locally encrypted content using a shared local encryption key. The Transport I/O system ensures the protection of the network control word by maintaining the network control word on the secure processor.

摘要:
An electronic device determines to transmit an image including a matrix code to a display, receives input specifying to alter the matrix code, generates an updated image according to the input, and transmits the updated image to the display. The device may alter a size and/or position of the matrix code, a display duration and/or complexity of the matrix code, and so on. The device may generate the matrix code and modify it in response to input, receive different matrix code versions and select a different version in response to input, receive the image including the matrix code and generate a replacement to overlay over the image, and so on Additionally, independent of input, the device may receive an image, detect an included first matrix code, generate a second matrix code based on the first, and generate an updated image by adding the second matrix code to the image.
