Provided is an image data processing method. First, decoding processing designed (step S1) in such a manner that a moving picture X is singly processed and that a moving picture Y and Z having low vertical resolutions can be combined together to be subjected to decoding processing. Subsequently, each of the moving picture X, Y, and Z is encoded (step S2). Next, encoded data of the moving picture X is singly decoded, and the moving picture X is restored and displayed on a display unit of the image processing device at a predetermined timing. Meanwhile, respective pieces of encoded data of the moving picture Y and Z are combined together and are decoded depending on respective display timings, and the moving picture X and Y are restored and further separated from each other to be displayed on the display unit at the respective timings (step S3).

Systems and methods for error detection in video data is described. An encoding computing system can receive a video frame. The encoding computing system can encode and decode the video frame based on an encoding scheme. The encoding computing system can generate a frame error detection code for the decoded video frame based on an error detection code generation scheme. The encoding computing system can send the encoded video frame and the error detection code to a decoding computing system. The decoding computing system can decode the encoded video frame and generate a second error detection code using the code generation scheme. The decoding computing system can detect that the decoded video frame is corrupted by comparing the error detection code and the second error detection code.

Provided is an image data processing method for preventing decrease of a decoding processing capability of an image processing device even if the image processing device is included in a game machine on which many moving pictures having low resolutions are displayed. First, decoding processing is designed (step S1). For example, it is designed in such a manner that a moving picture X is singly processed and that a moving picture Y and a moving picture Z having low vertical resolutions can be combined together to be subjected to decoding processing. Subsequently, each of the moving picture X, the moving picture Y, and the moving picture Z is encoded (step S2). Next, encoded data of the moving picture X is singly decoded, and the moving picture X is restored and displayed on a display unit of the image processing device at a predetermined timing. Meanwhile, respective pieces of encoded data of the moving picture Y and the moving picture Z are combined together and are decoded depending on respective display timings, and the moving picture X and the moving picture Y are restored and further separated from each other to be displayed on the display unit at the respective timings (step S3).

In various embodiments, a subtitle timing application detects timing errors between subtitles and shot changes. In operation, the subtitle timing application determines that a temporal edge associated with a subtitle does not satisfy a timing guideline based on a shot change. The shot change occurs within a sequence of frames of an audiovisual program. The subtitle timing application then determines a new temporal edge that satisfies the timing guideline relative to the shot change. Subsequently, the subtitle timing application causes a modification to a temporal location of the subtitle within the sequence of frames based on the new temporal edge. Advantageously, the modification to the subtitle improves a quality of a viewing experience for a viewer. Notably, by automatically detecting timing errors, the subtitle timing application facilitates proper and efficient re-scheduling of subtitles that are not optimally timed with shot changes.

It is contemplated that the present invention can provide methods and systems for the near-simultaneous frame acquisition from multiple cameras. This can be achieved in two different ways. If the cameras are set to work in triggering mode, the triggering of a first camera and a subsequent camera are adjusted by overlapping the trigger signals and image communication control signals of each camera in order to capture near-simultaneous images from each of the cameras. If the cameras are in video mode, they will be kept synchronous by using a common clock and starting them at the same time. As each camera generates frames, individual, corresponding frames are sampled from each camera in a sequential manner upon receiving a triggering signal. In this way, near simultaneous images can be sampled and saved from multiple cameras in video mode.
