摘要： Systems and methods for voice activated commands in a digital home communication terminal are disclosed. One example method includes storing a program audio signal corresponding to a program tuned by the digital home communication terminal. The method also includes storing an incoming audio signal carrying speech and removing from the incoming audio signal a portion of the incoming audio signal that corresponds to the program audio signal, this producing an improved version of the incoming audio signal. The method also includes selecting one of a plurality of voice-activated commands that corresponds to the improved version of the incoming audio signal, and performing a function corresponding to the selected voice-activated command.

摘要： 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. Additionally, because the electronic device processes the digitized voice received from the remote control device, the electronic device can negate the effect of sounds, such as television audio, likely captured by the microphone on the remote control device. This results in a great capability of the electronic device to interpret user commands.
摘要翻译： 一种在远程控制设备麦克风处接收语音命令的方法，装置和系统，对那些输入语音命令进行数字化，压缩数字化语音命令，用压缩的数字化语音命令复用控制命令，并将压缩的数字化语音命令发送到电子设备 ，例如数字家庭通信终端（DCHT）。 电子设备解压缩和解释语音命令，以允许遥控操作员控制电子设备。 因为在电子设备而不是在遥控设备处执行语音识别，所以遥控器不必解释和发送表示用户命令的红外信号。 这简化了遥控器所需的处理和语音识别功能。 此外，由于电子设备处理从遥控设备接收的数字化声音，所以电子设备可以抵消可能由麦克风在遥控设备上捕获的诸如电视音频的声音的影响。 这导致电子设备解释用户命令的巨大能力。

摘要： 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. It further saves IP addresses by assigning a non-unique IP address to the router for use inside the LAN. When the CATV system fails, the asymmetrical network automatically begins to use the telephone line as both the up link and the down link, and when the CATV system is restored, the asymmetrical network automatically returns to using the CATV cable as the down link and the telephone line as the up link. A further feature of the asymmetrical network is that the head end components and the RF modem have IP addresses, so that standard TCP/IP protocols can be used to control the asymmetrical network.

摘要： 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.
