摘要： A method and apparatus is described to achieve a fast service change. The method includes: receiving a plurality of transport streams at a client device, each transport stream including a plurality of encrypted services; decrypting an encrypted service from the plurality of encrypted services thereby forming a decrypted service; playing out the decrypted service; storing a portion of at least one encrypted service from the plurality of encrypted services in a storage device; receiving a request for displaying a different encrypted service; identifying a stored portion of the different encrypted service; decrypting the stored portion of the different encrypted service thereby forming a decrypted stored portion; playing out the decrypted stored portion of the different encrypted service at a faster than real time speed; storing a subsequent portion of the different encrypted service in the storage device, the subsequent portion corresponding to a subsequent portion of the different encrypted service received during the decrypting of the stored portion and the playing out the decrypted stored portion of the different encrypted service; decrypting the subsequent stored portion of the different encrypted service thereby forming a decrypted subsequent portion; and playing out the decrypted subsequent portion of the different encrypted service for display upon completion of the playing out of the decrypted stored portion.

摘要： A circuit includes an input node configured to receive a test address input signal and circuitry configured to generate, from a first part of the test address input signal, a first address signal that selects a first address of a first part of a circuit to be tested and further generate, from a second part of the test address input signal, a second signal configured to select a second part of the circuit to be tested. Test circuitry is then configured to use the first address and the second part in a test mode.

摘要： A system for testing faults in shadow logic includes a sequential block coupled to a shadow logic block and a delaying block to receive test patterns for testing the shadow logic block. The delaying block delays the test patterns by an access time of the sequential block to generate delayed test patterns. The delayed test patterns are passed to the shadow logic block for testing faults.
