Set-top box and digital TV
The term set-top box (STB) is widely used for consumer electronic devices capable to receive video content according to DVB standard and display it on TV. The development of IP networks and broadband/ADSL made possible to deliver a video content of good quality and to appear IPTV set-top boxes.
Overview of processor (system on chip) producers for STB
Being oriented to the mass-production consumer electronics, STB chipset manufacturers are forced to integrate more peripherals in a chip and to produce lower cost single chip solutions for BOM reduction and cutting price of a final STB device. Usually, the chip inside STB consists of 3 or more cores: a general purpose application processor and additional DSP-like cores dedicated to audio and video decoding.
Let's give a short overview of major semiconductor companies which produce processors (system-on-chip) for set-top boxes:
