Abstract
A signal processing apparatus receives a signal train including image signals of a plurality of frames and additional signals added to the image signals on a frame unit basis for controlling the processes for the image signals, delays the received image signals in accordance with the additional signals, and processes the delayed image signals in accordance with the additional signals.
Claims21
A signal processing apparatus, comprising:
- an input unit that inputs a multiplexed information signal train including image signals of a plurality of frames and additional signals for controlling a process for the image signals, the additional signals being multiplexed on the image signals on a frame unit basis in the multiplexed information signal train;
- a delay unit that delays the image signals inputted by said input unit;
- a processing unit that processes the image signals outputted from said delay unit;
- and
- a control unit that controls each of a process operation of said processing unit and a delay operation of said delay unit independently, in accordance with the additional signals inputted by said input unit.
2 more elements
A signal processing system, comprising:
- a reproduction apparatus for reproducing a digital image signal of a plurality of frames, multiplexing the reproduced digital image signal and an additional signal for controlling a process for the digital image signal to generate a multiplexed information signal train, and outputting the multiplexed information signal train, said reproduction apparatus multiplexing the additional signal and the digital image signal on a frame unit basis;
- and
- a signal processing apparatus, comprising:
- an input unit that inputs the multiplexed information signal train outputted from said reproduction apparatus;
- a delay unit that delays an inputted digital image signal from said input unit;
- a processing unit that processes the digital image signal outputted from said delay unit;
- and
- a control unit that controls each of a process operation to be executed by said processing unit and a delay operation to be executed by said delay unit independently, in accordance with the additional signal.
5 more elements
A signal processing method comprising the steps of:
- inputting a multiplexed information signal train including image signals of a plurality of frames and additional signals for controlling a process for the image signals, the additional signals being multiplexed on the image signals on a frame unit basis in the multiplexed information signal train;
- delaying the image signals inputted in said inputting step;
- processing the delayed image signals;
- and
- controlling each of a process operation in said processing step and a delay operation in said delaying step independently, in accordance with the additional signals inputted in said inputting step.
2 more elements
A signal processing apparatus for executing a plurality of kinds of processes for an image signal, comprising:
- an input unit that inputs a multiplexed information signal train including image signals of a plurality of frames and additional signals indicating a selected kind of process from the plurality of kinds of processes for the image signals, the additional signals being multiplexed on the image signals on a frame unit basis in the multiplexed information signal train;
- a delay unit that delays the image signals inputted by said input unit;
- a process unit that processes the image signals outputted from said delay unit;
- a separation unit that separates an additional signal from the multiplexed information signal train inputted by said input unit;
- and
- a control unit that controls each of said process unit to execute the selected kind of process and a delay time of said delay unit independently, in accordance with the additional signal separated by said separation unit.
