Patent number: 9495969Abstract: A received transport stream may be demultiplexed into a compressed audio stream and a control stream. The compressed audio stream may be decoded. Audio corresponding to a tuned program may be stored. The stored audio may be separated from the compressed audio stream by subtracting the stored audio from the decoded audio stream, until a no-active-speech command is found in the control stream. Responsive to the no-active-speech command, the subtracting may be omitted for a period corresponding to a duration of the no-active-speech command.Type: GrantFiled: July 31, 2014Date of Patent: November 15, 2016Assignee: Cisco Technology, Inc.Inventors: Arturo A. Rodriguez, David A. Sedacca, Albert Garcia

Patent number: 7519999Abstract: A digital subscriber communication terminal includes an adaptive output interface having a device key set, which, along with a subscriber device coupled to the adaptive output interface, determines a “shared secret.” The adaptive output interface uses the “shared secret” to encrypt content and transmits the content to the subscriber device coupled to the adaptive output interface. The digital subscriber communications terminal includes a processor, a memory having an encrypted device key set and an encrypted device key set decryptor stored therein and a secure element having a key decryptor. The secure element is adapted to receive the encrypted device key set decryptor and use the key decryptor to decrypt the encrypted device key set decryptor. The device key set decryptor is provided to the processor, which decrypts the encrypted device key set using the device key set decryptor, and the device key set is loaded into the adaptive output interface.Type: GrantFiled: February 27, 2004Date of Patent: April 14, 2009Assignee: Scientific-Atlanta, Inc.Inventor: David A.

Patent number: 7321857Abstract: A method, apparatus and system that receives speech commands at a remote control device microphone, digitizes those input speech commands, compresses the digitized speech commands, multiplexes control commands with the compressed digitized speech commands, and transmits the compressed digitized speech commands to an electronic device, such as a digital home communication terminal (DCHT). The electronic device decompresses and interprets the speech commands to allow the remote control operator to control the electronic device. Because speech recognition is performed at the electronic device, rather than at the remote control device, the remote control does not have to interpret and transmit infrared signals that represent user commands. This simplifies the processing and voice recognition capabilities required by the remote control.Type: GrantFiled: January 10, 2005Date of Patent: January 22, 2008Assignee: Scientific-Atlanta, Inc.Inventors: Arturo A. Rodriguez, David A. Sedacca, Albert Garcia

Patent number: 6295298Abstract: An asymmetrical network for coupling customer-premises Internet hosts such as personal computers to the Internet. The head end of a CATV system has a high-bandwidth connection to the Internet. The down ink conning the personal computers to the Internet is the cables provided by the CATV system; the up link is a telephone connection to the head end. A router is connected to the down link by means of an RF modem, to the up link by means of an analog modem, and to a LAN which is connected to the Pcs. The router routes IP packets for the hosts that are received on the CATV cable to the hosts via the LAN; it routes IP packets from the hosts that are destined for the Internet to the head end via the telephone line. The asymmetrical network conserves IP addresses and addresses on the CATV cable by dynamically allocating the IP addresses for an RF modem's hosts and an address on the CATV cable for the RF modem in response to a request made by the RF modem via the telephone line.Type: GrantFiled: March 11, 1997Date of Patent: September 25, 2001Assignee: Scientific-Atlanta, Inc.Inventors: Scott E.
