- MEDIA indicating the type of media (s) of a content, the type of encoding (for example MPEG4) and the resolution (for example SD) supported, and a range of associated bit rates (lMbits / s at 3Mbits / s);
- a "CONNECTION" column indicating the type of connection supported by the processing device for one or more functions.
- the device supports two functions:
- NET network function
- WI-FI WI-FI
- ETH Ethernet
- a power function indicates the types of possible connections to power the device; the possible power modes are here serial (USB) or mains (SEC), and the power supply has two powers 1 and 2 (SEC1 and SEC2); by for example, the user uses a power supply that is not provided for the key (SEC1) and delivers a reduced power or the original power supply of the key (SEC) which delivers a higher power;
- MESSAGE A message column
- the terminal TA of the user connects to the TV key CTV.
- This connection is made in a conventional manner between the two devices, by a communication between a mobile application running on the terminal TA and a corresponding application on the TV key CTV.
- the terminal TA submits a request to receive a content C via the key CTV (5) and return it on its TV.
- This request is received in step E2 by the key CTV, which analyzes it.
- the request is of type "restitution of the content C in HD on the TV".
- the CAP module of the key CTV accesses during this step E2 to the description file MPD. It can download it for example on the content server (3), or on the service gateway, or access it locally, etc. It deduces the detailed characteristics of the content requested from it.
- the TV key analyzes the description file and deduces that it must provide the content C in high definition at 10Mbit / s in HEVC, corresponding to the following URL (for the first fragment) if we refer to the manifest file given as an example in Annex 1:
- the key CTV consults the file of the FCC capacities that it has in memory and acquires knowledge of the current configuration of the device corresponding to the various functions in this file.
- the CAP module of the key CTV obtains the current state of the key relative to the two functions (modes of connection ALIM and NET) concerned. For example :
- the TV key is connected in Wi-FI and connected to the mains (SEC1),
- the TV key is connected in Ethernet (ETH) and powered by USB,
- the CAP module of the CTV key analyzes the capabilities required for the requested media and compares them with the current connections of the key.
- it must deliver HD content in HEVC at a rate of 10Mbit / s (line 6 of table 1);
- it must perform the following two functions: a WiFI connection to the network and a minimum type of mains connection SEC 1.
- the comparison, or test of adequacy will be negative (the service can not be rendered in the same way). 'state') or positive (the service can be returned as is).
- the test is positive, it does not prepare a message.
- the content accesses the request. It optionally transmits an acknowledgment to the terminal in a next step E5, then requests the content from the server and begins downloading and returning the content C required during step E6 (restitution symbolized by the curved arrow).
- the Media Player (MP) receives the content from the service gateway, decodes it, formats it, makes it play as it is received and transmits it to the associated rendering device (TV).
- step E4 is followed by a step E7, during which a message is sent to the user asking him to activate, for at least one function, a connection required for playback: mains connection, Ethernet connection, etc.
- the TV key is connected in Wi-FI and connected to the mains with a power charger SEC1; if the requested content (HEVC Stream in 4K at 25Mbit / s) requires (line 7, table 1) a power supply supplied natively with the device (SEC2) and an Ethernet connection to the service gateway, the message displayed at the user is: "Connect the key to native power and Ethernet"
- a step E26 the user performs such a connection action, taken into account during a step E8 (for example, the electrical state of the key is changed from a USB power state to a state power supply since the user has plugged in his key).
- the CAP module on the key then returns to step E4 to verify that the requested action has been performed. If so, it continues with step E5 to stream the content.
- Step E10 terminates the restitution of the content.
- - display connectivity for example, the key can be connected to a rendering device in VGA or HDMI
- memory connectivity for example, the key can be connected to an external hard drive which is only useful in certain use cases, especially if the content has to be registered
