  • Publication number: 20020010390
    Abstract: A method and system (i.e., an Automated Animal Health Monitoring System—AAHMS) for automated monitoring and early warning of changes in parameters related to the health and status of animals is disclosed. The system includes implantable wireless “smart tele-sensor” elements that can be implanted within the animal where they measure, and may transmit, temperature and other parameters (e.g., blood oxygen, accelerations, vibrations, heart rate) related to the health and status of the animal being monitored. Optional relay elements may comprise simple transponders to boost the signals from the smart sensor elements and retransmit processed results. The system includes devices for alerting personnel responsible for care of the animals and identifying the animal needing attention.

  • Patent number: 5838874
    Abstract: An audiovisual encoding system using a multipass video encoder and a plurality of one-pass audio encoders. The number of audio encoders used by the system is equal to the number of audio tracks to be encoded divided by the number of passes required for the video encoding rounded up to the nearest integer, if necessary. The system allows the video encoder and audio encoders to be used at the same time so that the encoding of the video is completed at the same time as the encoding of all audio tracks is completed, using the minimum number of audio encoders.

  • Patent number: 5819004
    Abstract: A method and system in which a user manually changes the quality of portions of video frames after the frames have been previously encoded. Regions of one or more frames of video are selected to have an increased quality, a decreased quality, or a quality which should not be altered. After the regions are defined by a user, the frame of video is digitally re-encoded and inserted into the digitally encoded data stream in place of the previously encoded data. In order to easily remove a previously encoded frame from the data steam and replace it with a newly encoded frame having regions of quality defined by the user, it is preferable to have the newly encoded frame consume the same number of bits as the previously encoded frame. Accordingly, if the user desires a region of a frame to have an increased quality, the extra bits necessary to provide the increased quality must be taken from other areas of the frame. This is accomplished by an automatic process which is transparent to the user.

  • Patent number: 5684714
    Abstract: A method and system in which a user manually changes the quality of specific time periods of encoded video. After the automatic encoding of video into a compressed digital format, a person editing the encoded video reviews the quality of the video and manually indicates that the quality of specific time periods of the video is to be altered. As the digital storage medium such as an optical disc which stores the encoded video has a finite storage capacity, the total number of bits for the encoded video and the quality of the video is limited. Consequently, in order to increase the quality for one time period, bits must be taken from other time periods. After the editor assigns the qualities to different time periods, a percentage of bits is removed from the time sequences and placed into a bit pool. The new number of bits for the various time periods are calculated using an exponential function and the bits in the bit pool are proportionally distributed to the video frames.
