Siano's advanced SMS1530, which supports the Advanced Television Systems Committee (ATSC) A/153 Mobile Digital TV Standard, was developed in collaboration with LG Electronics, principal developer of the ATSC M/H (mobile/handheld) broadcast standard. Optimized for transmission to mobile and handheld devices, ATSC Mobile DTV was developed to support a variety of services including free (advertiser-supported) television and interactive services delivered in real time, subscription-based TV, and file-based content download for playback at a later time. The standard can also be used for transmission of new data broadcasting services. The SMS1530 is fully compatible with the ATSC A/153 Standard. In addition, it supports FM radio, and has the necessary on-chip provisions for conditional access for pay-TV services. The high-performance, low-power SMS1530 targets a wide range of mobile and handheld devices, including mobile phones, portable navigation devices, in-vehicle TVs and portable media players.
