Embodiment Construction

[0037] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which specific embodiments of the invention are shown. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided by way of example so that this disclosure will be thorough and complete, and will inform the art The skilled artisan fully conveys the scope of the present invention. Like reference numerals refer to like elements throughout.

[0038] Digital images are represented by pixels. Each pixel is represented by a number of values ​​that define the appearance of that pixel. Depending on the image processing mechanism used for the image, these values ​​can represent different characteristics of the pixel. In some schemes, pixels are represented by three color values, such as RGB, CMY, etc. In other mechanisms, pixels are represented...

Abstract

The present invention relates to a method, an encoder, a computer program product, and a system for real-time encoding. The encoder (500) is arranged to receive movement information about a movement of a camera (504), the encoder (500) being arranged to encode, in real-time, a video stream acquired by the camera (504) during the movement of the camera (504), wherein the encoder (500) is arranged to encode based on said movement information. The movement information may be stored in a memory (502).

Description

technical field [0001] The present invention relates to methods, encoders, computer program products and systems for real-time encoding. Background technique [0002] Digital video systems typically deliver a series of digital images from a source like a camera to a destination like a display. The transfer can be from the camera directly to the live display, or the transfer can be delayed in time by storing the video and displaying it later. Digital images can be compressed or delivered in their native format. [0003] The problem with real-time encoding is that it is difficult to plan bitrate usage over time since there is no information about the future. Bursts in transit, high bit-rate peaks in the transmission of digital images from source to destination, are possible and difficult to predict. Therefore, there is a need for a method for real-time encoding of video that can plan bitrate usage. Contents of the invention [0004] In view of the above, it is an object ...
