India Latest Technology - NANO
The much awaited Tata small car, which is giving sleepless nights to its rivals, was finally unveiled at the Auto Expo 2008. The small car, which is priced at Rs100, 000 (2,500 dollars), has been named Nano. According to the Tata Motors, the Nano will hit the Indian roads later this year. Ever since the Tatas announced their intention of developing the 1 lakh car (touted as people’s car), the auto industry experts have been raising doubts over the price, features, safety and specifications of Tata Nano. Have a look at specifications and other aspects of the Tata Nano, the four door mini-hatchback.
Looks & Dimensions of Nano: Keeping in mind the young age group, the Tata Motors has strived well to give the Nano a contemporary and stylish look. The snub-nosed small car derives inspiration from Fiat 500 and Nissan Micra. As far as dimensions of the car are concerned, Nano is 3.1 metres (10.23 feet) long, 1.5 metres wide and 1.6 metres high and can accommodate four to five people.
Engine: The small car sports a two cylinder 623 cc, 33 horsepower rear mounted multi-point fuel injection (MPFi) petrol engine. Tata claims that the car can touch the top speed of 105 kms.
Fuel Efficiency: Engineers at Tata Motors have designed an efficient engine that can run 20 Kms on every litre of petrol.
Pollution: Against the criticism and concerns of the environmentalists, Nano surpasses Indian regulatory requirements and Euro IV emission norms. In fact, Tata claims that the small car is less polluting than most of the bikes on Indian roads.
Safety: Tata says that they have tested the small car extensively for front, rear and side collisions and come out with a product that exceeds current regulatory requirements. The safety features of the Nano include a strong passenger compartment, intrusion resistant doors, seat belts, sturdy seats and anchorage.
Price: The base model of the car will sport a price tag of Rs 100,000 (2,500 dollars) which excludes taxes and transport costs. The high end/deluxe models will include air-conditioning and other features to be incorporated based on suggestions of the common people
Real Time Messaging Protocol (RTMP) is a proprietary protocol developed by Adobe Systems for streaming audio, video and data over the Internet, between a Flash player and a server.
The RTMP protocol has three variations:
The "plain" protocol which works on top of TCP and uses port number 1935
RTMPT which is encapsulated within HTTP requests to traverse firewalls
RTMPS which works just like RTMPT, but over a secure HTTPS connection.
While the primary motivation for RTMP was a persistent protocol for Flash, it is also used in some other applications, such as the Adobe LiveCycle Data Services ES.
Client → Server : Sends Handshake Request. This is not a protocol packet but a single byte (0×03) followed by 1536 bytes. This content does not seem to be vital for the protocol, but is not random either. See 1)
Server → Client : Sends a Handshake Response. This is not a RTMP packet but a single byte (0×03) followed by two 1536 byte chunks (so a total of 3072 raw bytes). The second chunk of bytes is the original client request bytes sent in handshake request. The first chunk can be anything. Use null bytes it doesnt seem to matter.
Client→Server: Sends 1536 raw bytes which are the second 1536 chunk of server generated handshake.
At this time, handshake is done and further packets are RTMP ones.
Client → Server : send the Connect RTMP packet.
Server → Client : Server responds
...and so on...
