TiVo Awarded Two New Patents

Patents Cover Core DVR Functions and Home Networking Capabilities (December 11, 2001)
TiVo today announced it has been granted additional patents for its technology and service. The first patent protects the functions that are the core of digital recording devices. The second patent covers inventions that enable simple and reliable networking of multiple streaming media devices in the home.

The TrickPlay patent issued by the United States Patent office as number 6,327,418, describes a method of controlling streaming media in a digital device. In today's implementation of a TiVo DVR, the TrickPlay patent covers the functions that enable TiVo subscribers to pause live TV as well as rewind, fast forward, play, play faster, play slower, and play in reverse television signals cached by the DVR. Storing, editing and manipulation of video are also among the 64 claims supported by the TrickPlay patent.

Combined with TiVo's Time Warp patent [USPTO No. 6,233,389] which enables the simultaneous recording and playback of multiple streams as well as efficient and low-cost processing, synchronization, and storage of multimedia streams, the TrickPlay patent ensures that TiVo's patent portfolio covers the key functions that are essential to operate the TiVo DVR.

"The ability to pause live TV is one of the most desirable DVR functions. The combination of TiVo's TimeWarp patent issued earlier this year and the TrickPlay patent we are announcing today protects all the basic inventions that make TiVo the product our customers enjoy today and insures it will be the product of the future," said Jim Barton, Chief Technology Officer for TiVo. "These patents further bolster our licensing business and protect current and future licensees using TiVo technology."

The Home Networking patent issued as USPTO number 6,310,886 describes a simple and reliable method for connecting TiVo DVRs and other streaming media devices to a network in the home. This technology allows TiVo to extend the ease of use of its current product and service to digital entertainment that can be enjoyed throughout the home.

"Our foundation technology for DVRs is just the beginning, and we continue to extend that technology looking forward to the networked multimedia home of the future," continued Barton. "Televisions, radios, telephones and the PC are some of the products that could access media on a home network. We look forward to not only the continued proliferation of TiVo DVR's but to the future of home entertainment."
