    • Providing content to content receiving devices, such as digital video recorders, connected to a computer network through a content provider is described. According to one aspect, a server maintains a database correlating contact information to content receiving devices in its network. A user navigates to a web site of the content provider and selects a piece of content, which prompts the content provider to query the server for the contact information, and then transmit a request to download the piece of content to the content receiving device. The request can be a set of content identification information that automatically populates a content guide at the receiving device with an entry corresponding to the requested piece of content. This entry allows the user to confirm, interrupt, resume and cancel a download of the content as desired.

    • In one embodiment, an apparatus comprises a camera and a group of light emitting diodes configured and arranged to illuminate an object imaged by the camera. The group of LEDs comprises at least one first LED of a first type that emits light with a first spectrum profile and at least one second LED of a second type that emits light with a second spectrum profile that is substantially different than the first spectrum profile. The apparatus may further comprise an adjustment mechanism for adjusting of the relative amounts of illumination energy generated by the at least one first LED and the at least one second LED during each of a plurality of scan cycles of the camera.
    • 在一个实施例中,一种装置包括照相机和一组发光二极管,其被配置和布置成照亮由照相机成像的物体。 LED组包括发射具有第一光谱分布的光的第一类型的至少一个第一LED和第二类型的至少一个第二类型的第二LED,其具有与第一光谱分布基本不同的第二光谱分布。 该装置还可以包括调整机构,用于在相机的多个扫描周期的每一个期间调整由至少一个第一LED和至少一个第二LED产生的照明能量的相对量。
