    • A method and system for testing the performance of at least one electro-optical test device, comprising constructing an electro-optical system having a light source, a test target, a lens and an imaging device as required in combination with the test devices. A respective identity code of a plurality of precalibrated devices together with corresponding electro-optical performances are stored in a database and the imaging device is aligned to the test target so as to produce a focused image thereof. Pre-calibbrated devices are selected from the database and the focussed image is digitized and stored so as to produce a digitized image which is analyzed so as to determine an electro-optical performance representative of the performance of the electro-optical system which is equal to the product of component electro-optical performances of each of the electro-optical test devices and each of the additional pre-calibrated devices. This permits determination of the product of component electro-optical performances of each of the electro-optical test devices.
    • 一种用于测试至少一个电光测试装置的性能的方法和系统,包括根据需要构建具有光源,测试目标,透镜和成像装置的电光系统,结合测试装置。 将多个预校准装置的相应识别码与相应的电光性能一起存储在数据库中,并且成像装置与测试对象对准,以便产生其聚焦图像。 从数据库中选择预加工设备,并且对聚焦图像进行数字化和存储,以便产生被分析的数字化图像,以便确定代表电光学系统的性能的电光性能,其等于 每个电光测试设备和每个附加的预校准设备的分量电光性能的乘积。 这允许确定每个电光测试装置的部件电光性能的乘积。

    • Methods of operating a portable media device 100 including two onboard hardware media decoders (124, 128) operative to decode a given digital content item 148 are disclosed. In some embodiments, one of the onboard hardware media decoders 128 has a relatively high power consumption and produces a relatively ‘high quality’ media signal, and the other of the onboard hardware media decoder 124 has a relatively low power consumption and produces a relatively ‘low quality’ media signal. In one non-limiting use case: (i) when no external power is available, the relatively ‘low power’ hardware media decoder 124 may generate a relatively ‘low quality’ media signal which is presented on an onboard display screen 140a and/or onboard speaker 140b; and (ii) when external power is available, the relatively ‘high power’ hardware media decoder 128 may generate a relatively ‘high quality’ media signal which is exported out of the portable media device 100 via one or more media ports, and presented on an external host presentation device 160 (for example, a large-screen television).
    • 公开了操作便携式媒体设备100的方法,该便携式媒体设备100包括可操作以解码给定数字内容项目148的两个板上硬件媒体解码器(124,128)。 在一些实施例中,车载硬件介质解码器128中的一个具有相对高的功率消耗并产生相对“高品质”的媒体信号,并且车载硬件媒体解码器124中的另一个具有相对低的功率消耗并产生相对“ 低品质“媒体信号。 在一个非限制性使用情况下:(i)当没有外部电源可用时,相对“低功率”硬件媒体解码器124可以产生呈现在车载显示屏140a上的相对“低质量”媒体信号和/或 车载扬声器140b; 和(ii)当外部电源可用时,相对“高功率”的硬件媒体解码器128可以产生相对“高品质”的媒体信号,其通过一个或多个媒体端口从便携式媒体设备100导出, 外部主机呈现装置160(例如,大屏幕电视)。
