Different phases shown in the flow diagrams may be combined with each other and the order of phases may be changed except where otherwise explicitly defined. Furthermore, it is to be noted that performing all phases of the flow diagram is not mandatory. n The flow diagram of Fig. 3 comprises the following phases:
N 301: Digital live content is received. The digital live content is generated in the - 25 wireless multimedia device. The digital live content may be generated in the
S application implementing various features of present disclosure or in some other z application. There may be for example a separate video application that generates
I the content that is then further processed in a different application according to 3 present disclosure.
N
302: One or more operating context parameters are determined. The operating context parameters are associated with operating context of the wireless multimedia device.
The operating context parameters may concern device context related to operation of the wireless multimedia device and/or network context related to operation of the wireless network to which the wireless multimedia device is connected.
The operating context parameters concerning the device context may comprise parameters related to one or more of the following: battery status, processor load, device temperature, humidity, device location, time, characteristics of an event related to the digital live content (such as duration, location, type).
The operating context parameters concerning the network context may comprise parameters related to one or more of the following: available resources of the wireless network, available uplink resources of the wireless network, coverage of the wireless network, type of the wireless network (e.g. 3G, 4G, 5G, Wifi, 2G/5G), — parameters related to operation of the wireless network, such as ping or jitter.
The operating context parameters may be determined based on sensors of the wireless multimedia device (e.g. temperature sensor, humidity sensor), based on tools readily available in the wireless multimedia device (e.g. GPS, clock), based on information received from the wireless network or information readily available in the wireless multimedia device for the purpose of wireless communications (e.g. available resources of the wireless network, type of the wireless network, parameters related to operation of the wireless network), based on information — available from other applications (e.g. duration of a live event from calendar or other
O tools). = 25 303: Platform identification information for multiple social media platforms is
S received. The social media platforms may include for example a selection of the = following: Facebook, YouTube, Instagram, WhatsApp, Snapchat, Twitter, TikTok,
I LinkedIn and the like. The social media platforms may be for example preselected 8 by a user.
O
N 30 304: The digital live content is processed based on the platform identification information and the operating context parameters so that live stream is generated for each of the social media platforms. The generated live steams of different social media platforms may have different properties. In some cases, live streams of at least some of the social media platforms may have equal properties. That is, the live streams are individually generated for each social media platform or properties of the live streams are individually adjusted for each social media platform.
For example, if operating context parameters indicate limited resources in the wireless multimedia device and/or in the wireless network, available resources may be focused on live streams of a subset of social media platforms, whilst live streams of some other social media platforms may receive limited resources. Alternatively, — resource use of all live streams may be limited.
In some embodiments, resolution of the live stream is adjusted in phase 304. The resolution may be different for different social media platforms for example if the operating context parameters indicate that there are not enough resources to provide the highest possible resolution for all social media platforms.
In some embodiments, phase 304 may comprise that one or more of the live streams are scheduled to temporarily stop in certain conditions and/or to resume when some other criteria are fulfilled.
In some embodiments, the multiple social media platforms may be associated with priority classes. The priority classes may be (pre) selected by a user or the social media platforms may be automatically arranged in priority order. The automatic arrangement may be based on random order or intelligent arrangement based on historical information about live stream transmissions of the associated user and/or - wireless multimedia device. The priority classes may then be taken into account in
O phase 304 in generation of the live streams of different social media platforms. For
O 25 example, the live stream of the social media platform having the highest priority may © be adjusted to have better quality than other live streams. Additionally or z alternatively, the live stream of the social media platform having a lower priority may 5 be temporarily paused if operating context parameters indicate limited resources in 3 the wireless multimedia device and/or in the wireless network.
O 30 It is to be noted that even without explicit priority classes or priority order, the live streams generated for the different social media platforms may have different properties. Depending on the implementation, each live stream may be adjusted in similar manner or different type of adjustments may be made in live streams of different social media platforms even without the priority classes. 305: The generated live streams are provided for transmission from the wireless multimedia device to the multiple social media platforms over the wireless network.
In some embodiments, the one or more operating context parameters are continuously determined and monitored and processing of the digital live content is accordingly adjusted. That is, for example resolution of one or more live streams may be adjusted during transmission of the live streams and/or one or more live streams may be temporarily paused and later resumed.
Inthe following, some non-limiting examples are discussed. In these examples three social media platforms are concerned and these are referred to as SMP1, SMP2 and SMP3. The examples list operating context parameters that are determined, platform identification information of the social media platforms that are concerned, and properties of the live streams generated for the different social media platforms.

N 20 In some further embodiments, determination of the operating context parameters 2 comprises determining duration of a live event associated with the digital live
S content. This may be obtained e.g. from calendar, from Facebook event information
E: or the like. The live streams of different social media platforms may then be adjusted
I to optimize streaming so that battery of the wireless multimedia device does not die 3 25 during the event. For example, at least one live stream may be stopped and/or
S resolution for at least one live stream may be dropped.
In some further embodiments, determination of the operating context parameters comprises determining location and movements of the wireless multimedia device and predicting future route of the movements during the time period live streaming takes place. The prediction may be based on map information for example. Based on this it is possible to predict network coverage during the live streaming. The predicted network coverage may then be used for deciding on adjustments on the live streams.
Without in any way limiting the scope, interpretation, or application of the appended claims, a technical effect of one or more of the example embodiments disclosed herein is improved live streaming of digital live content to plurality of social media platforms. By individually adjusting the live streams of different social media platforms in the source device (i.e. in the wireless multimedia device where the digital live content is being generated), one achieves that if limited resources are available, it is possible to ensure good quality live stream at least to some social — media platforms. In this way risk of failing all transmissions of live stream may be reduced. Furthermore, high quality live stream to multiple social media platforms may be automatically provided to multiple social media platforms when sufficient resources are available. In this way, the transmissions of live streams automatically adapt to operating conditions and available resources.
If desired, the different functions discussed herein may be performed in a different order and/or concurrently with each other. Furthermore, if desired, one or more of the before-described functions may be optional or may be combined.
