Media Streamer Platforms Roundupby Ganesh T S on June 13, 2010 7:00 PM EST
Devices such as the Vudu and the Roku boxes fall under this category. They aim to do one thing and do it well by restricting themselves to some VOD services and presenting their users with an environment similar to DVD renting, only online. Local media can't be played through them. Some of the SOC platforms which have found traction in this market include NXP STB 236 and Broadcom BCM7401. These SOCs were primarily designed for the IP set top boxes (Vudu and Roku may also be termed IP set top boxes, but at a more basic level compared to what these were originally designed for). These platforms do not support DTS audio, which is pretty much a pre-requisite nowadays for products geared towards the media streaming audience.
The Roku HD streamer introduced recently utilizes the NXP platform with a 320 MHz MIPS32 host processor. The STB 236 platform uses the PNX8336 at its core. H264 and VC1 seem to be supported codecs for hardware acceleration, while MPEG-2 seems to be only partially supported. The SOC has suitable connectivity options including USB, SATA and Ethernet. However, HDMI is not integrated in the SOC. The PNX8336 was released in April 2008. Since then, NXP has released video decoder chips targeted towards the TV and the DVR markets in December 2008 and March 2009. However, they seem to miss the mark as far as the features required for a media streamer device go. It will be interesting to see what Roku has in its roadmap, and whether they would shift suppliers for future products. The Roku HD-XR has a USB port, but it serves no discernible usefulness at present. The unit has an operational power consumption of 6W.

Media Streamers Based on IP Set Top Box Platforms
Vudu, on the other hand, has realized that selling a restrictive IP set top box in this market is not an easy task. It is now striving to remodel itself as a service provider of sorts by integrating their software into the next generation Blu Ray players and TVs. Still, it is interesting to take a look at the platform behind their original device. It is based on Broadcom's BCM7401 (which also happens to have a 300 MHz MIPS32 host processor), which provides support for H264, VC-1 and MPEG-2 decode. Connectivity options include the standard set of USB, SATA and Ethernet. Now classified by Broadcom as a legacy product, this SOC has probably been superseded by the BCM7400 / BCM7400B introduced around the same time. It is also puzzling as to why the BCM7400B which provides support for DivX decoding wasn't used. That would have probably made the box closer to what the media streamer market needs. Vudu, unlike Roku, also provides the ability to purchase and download movies from their collection. This necessiates a hard disk inside their unit, which puts the operational power consumption much higher than Roku's at 18W.
All said and done, the days of these types of media streamers are numbered. They have to evolve themselves to different types of products in the coming years in order to survive in this market.
