1999 aug 25 6 philips semiconductors preliminary speci?cation stb5860 (set-top box) stb concept om5730 2.2 reference design goal the philips stb concept stb5860 is a reference design of a complete hardware and software solution intended for the digital satellite receiver set-top box market. this reference design addresses the potential customer base who is targeting the new world of digital media broadcasting. the reference platform for a set-top box combines the key ics, the saa7219 transport mpeg source decoder and the saa7215 family avg decoder/video encoder and the software to run a set-top box. as in many cases a platform is a stepping stone from which evolution and specification enhancements can be launched. the first reference design of the platform contains the necessary functions which demonstrate the performance and capabilities of the system. enhancements in the ics as well as for sw modules will be released during the lifetime of the platform. the convention which has been used is that backwards compatibility is guaranteed within the platform (stb5000 range). the main objectives are: firstly providing this complete system, greatly reduces the required investments needed in scarce design resources and helps customers focus on building a position and responding quickly to the market demand secondly, an advantage of the reference design approach is that the system consisting of complex functions realized in silicon and software can be validated in tangible results thirdly, to create a stable platform from which customized solutions can be derived faster. it is expected that in the coming years the market will grow in all segments, satellite, cable and terrestrial; and that the captive broadcasters gradually open up their system, focusing more on the services rather then the contents of the box. their service role at the beginning is to create the market by having box content, then it will change towards the real core service activities bringing content and new services to the home. this changing behaviour of the service providers calls for the semiconductor providers to offer competitive solutions, enabling the future dreams of the service providers. this implies that in order to plan the evolution of the set-top box functionality, one must be positioned and in control of the whole system. 2.3 bene?ts 2.3.1 k ey system benefits stb5860 offers a good compromise between flexibility, performance and integration of functions which leads to a very attractive price/performance offer. the saa7219 performs the descrambling, demultiplexing and control of the stb while the saa7215 family performs the media processing functions such as mpeg2 audio video and graphics processing. the communication between the two ics as well as the memory partitioning and management have been designed so that a true unified memory concept can be implemented with no performance degradation. within the stb family of products, hw and sw footprints will be maintained to ensure the maximum possible reuse of resources. philips offering the most comprehensive portfolio of ics combined with our well known technological capabilities brings the best on a complete system level. this in combination with our local technical support centres gives the customer a fast and secure inroad to the new field of emerging technology. 2.3.2 k ey ic benefits saa7219 incorporates a low cost high performance 32 bits mips processor with 4 kbytes instruction cache and 1-kbyte data cache. in addition a 4-kbyte second-level cache, designed for sw optimization but can also be used for last minute cpu intensive software patches is offered to software developers, boosting application performance. a flexible hardware/software partitioning and optimization for dvb ts demultiplexing has been designed targeted to canal+ specification. this partitioning makes parsing of incoming stream in hardware, in order to off-load the processor and makes most of the processing from system memory by the mips processor, which leaves to software developers the freedom to allocate the right priority at the application level for mpeg system data handling. all required dvb/mpeg2 system services are covered by the saa7219, such as full dvb descrambling, section filtering with 32 pids handled in hardware and more if required in software, ts/pes filter for maximum flexibility in the service handling and edition (time base discontinuity)
