Title:
MULTI-STREAM ENCODING CONTROL DEVICE AND CAMERA SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/042701
Kind Code:
A1
Abstract:
In a multi-stream encoding control device, when each video data is encoded by two or more mutually different coding systems, an encode prediction unit (204), in the encoding by each coding system in an encoding unit (202), determines the setting in the next encoding on the basis of any one or more of an code amount and an encode parameter after encoding, the code amount and encode parameter at encoding before the encoding, the frame rate to be encoded, and the output rate of an output unit (203). Thus, the total of code amount per unit time encoded respectively by a plurality of coding systems can be controlled in accordance with the transmission rate of the output unit 203. Hereby, when code data encoded respectively by a plurality of coding systems is outputted at the same time, the deterioration of image quality is suppressed and a high-resolution image can be delivered.
