A system and method for modifying media stream based on a channel limitation are disclosed. In one embodiment, the system includes a channel analyzer, a modality of interest (MOI) identification module and an inter-modality resolution modification module. The channel analyzer determines a channel limitation. The MOI identification module receives a plurality of media streams and identifies at least one MOI. The inter-modality resolution modification module modifies a resolution of at least one of the media streams based on the channel limitation and content of the media streams. In another embodiment, the system includes a region of interest identification (ROI) module and an intra-modality resolution modification module instead of, or in addition to, the MOI identification module and inter-modality resolution modification module. The ROI identification module receives a media stream and identifies at least one ROI within the media stream.

Media stream modification based on channel limitations

A device for assembling and adjusting an optical unit of the present invention includes an adjusting device including a collimator lens, an object lens, a disk, and a signal sensing system. A light beam output from the optical unit is incident to the collimator lens. Parallel rays output from the collimator lens are incident to the object leans. Further, a spot converged by the object lens is incident to the disk. The signal sensing system receives a light beam reflected by the disk via the object lens to thereby determine a distance between the object lens and the disk and a positional relation between the spot on the disk and the groove of the disk. The device allows the position of a light emitting element to be accurately determined and therefore allows the angular deviation of the intensity distribution of the light emitting element from a designed value to be easily grasped.
