  • Method and apparatus for improving video reproduction quality
    Patent number: 7174091
    Abstract: A delay detector detects a reproduction delay for a video signal based on a delay notification communicated from a manager to manage the reproduction delay using a state variable. A controller conducts delay recovery control by forcing an image quality improving unit to omit filtering based on the state variable or switching the type of filtering to a simpler one, while avoiding the need to omit decoding of a frame (i.e., frame skipping). This results in a reduction in a load on a processor and recovery of the reproduction delay.

  • Remote-controlled system, remote-control method
    Publication number: 20030143984
    Abstract: A remote-reservation apparatus, which is a remote-controlled one, receives reservations command for recording broadcast TV programs, from mobile telephones via the Internet. The apparatus generates reservation tables for the mobile telephones, respectively. When accessed by any mobile telephone, the remote-reservation apparatus identifies this mobile telephone and stores the reservation data transmitted from the mobile telephone, into the reservation table for the mobile telephone identified.

  • Video coding method and data processing device
    Publication number: 20020118756
    Abstract: Video data is compression-coded by an encoder. A processing state or the processing delay of the encoder is detected. The coding of the encoder is controlled based on the processing state of the coding so that a predetermined frame rate of the video data is maintained.
