Problems solved by technology

However, when designing and developing the above-mentioned pipeline devices, once there are function changes (for example: newly added features), parameter changes, error corrections, etc., the current technology is to judge the changes / corrections by human eyes and ears. Whether the video output and audio output are correct, because manual inspection is time-consuming and difficult to be accurate, automatic inspection technology is really necessary

Abstract

An embodiment of the invention discloses a multimedia pipeline type device. The multimedia pipeline type device comprises a plurality of first pipeline circuits and a processor. The first pipeline circuit comprises: a first circuit which generates first data according to input data and records feature information of the input data; and a second circuit which is used for generating second data according to the first data and recording characteristic information of the first data. The processor judges whether the feature information of the input data and the feature information of the first dataare correct or not according to the first pre-stored information and the second pre-stored information. At least one part of the first pre-stored information is information recorded by the first circuit in advance according to verified input data; at least one part of the second pre-stored information is information recorded by the second circuit in advance according to verified first data, the verified first data is generated by the first circuit according to the verified input data, and the verified input data and the input data are derived from the same multimedia test file.

Description

technical field [0001] The present invention relates to a multimedia pipeline device, in particular to a multimedia pipeline device capable of automatically checking whether video output and / or audio output is correct. Background technique [0002] In order to process multimedia data, a multimedia device (such as: television) usually includes a video pipeline device (video pipeline device) and an audio pipeline device (audio pipeline device), in order to process video data and audio data in order . However, when designing and developing the above-mentioned pipeline devices, once there are function changes (for example: newly added features), parameter changes, error corrections, etc., the current technology is to judge the changes / corrections by human eyes and ears. Whether the video output and audio output are correct, because manual inspection is time-consuming and difficult to be accurate, automatic inspection technology is really necessary.
