RECEPTION APPARATUS AND DATA PROCESSING METHOD
This technology relates to a reception apparatus and a data processing method for easily implementing circuits on the receiving side.
There is provided a reception apparatus including: a demodulation section configured to demodulate packets obtained with respect to each of multiple PLPs included in a broadcast signal; and a processing section configured to process the packets demodulated by the demodulation section. The demodulation section and the processing section are connected with each other via a single interface or interfaces fewer than the number of the PLPs. The demodulation section adds identification information to a specific packet among the packets obtained with respect to each of the PLP, the identification information identifying the PLP to which each of the packets belongs. The processing section identifies the PLP to which belongs each of the packets input from the demodulation section via the single interface or the interfaces fewer than the number of the PLPs, on the basis of the identification information obtained from the specific packet. This technology may be applied to television receivers, for example.
VIDEO PROCESSING SYSTEM FOR DEMULTIPLEXING RECEIVED COMPRESSED AND NON-COMPRESSED VIDEO SIGNALS AND TRANSMITTING DEMULTIPLEXED SIGNALS
The present invention is intended to permit both real-time display of a picture represented by a non-compressed video signal on a television and display of a picture represented by a compressed video signal at any desired time by simultaneously transmitting the compressed video signal and non-compressed video signal via one interface. An STB packetizes a compressed video signal, and multiplexes the compressed video signal and a blanking signal combined with a non-compressed video signal. Thus, both the video signals are transmitted simultaneously. A picture represented by the non-compressed video signal is displayed on a television in real time. The compressed video signal is stored in a storage medium incorporated in the television, read at any user's desired time, and decoded so that a picture represented by the compressed video signal can be viewed at the user's desired time.
Transmission method, reception method, transmitting apparatus, and receiving apparatus
A transmission method includes: dividing a picture into a plurality of regions; generating a plurality of pieces of encoded data that respectively correspond to the plurality of regions by encoding the plurality of regions such that each of the plurality of regions can be decoded independently; packetizing the generated plurality of pieces of encoded data into a plurality of packets such that pieces of encoded data for different regions are not stored in a single packet; and transmitting the plurality of packets. By this, workload for generation of decoding target data is reduced.
TRANSMISSION DEVICE, TRANSMISSION METHOD, RECEPTION DEVICE, AND RECEPTION METHOD
By a transmission method according to one aspect of the present disclosure, in a broadcasting system that generates a first broadcasting signal and a second broadcasting signal by performing multi-antenna encoding on program data, and wirelessly transmits a first broadcasting signal and a second broadcasting signal, a first transmit station transmits the first broadcasting signal, a second transmit station transmits the second broadcasting signal, the first transmit station and the second transmit station transmit the first broadcasting signal and the second broadcasting signal to an overlapping area at an identical time using an overlapping frequency band, polarized wave transmitted from the first transmit station differs from polarized wave transmitted from the second transmit station, and arrangement of the first transmit station differs from arrangement of the second transmit station.
Efficient scheme for reversing image data in a memory buffer
An apparatus comprising a plurality of image sensors configured to capture an image and a processor. The processor may comprise a buffer. The processor may be configured to (i) receive data from the image in a sequential order, (ii) perform cost calculations on the data, (iii) store the data in the buffer in a direction, (iv) when data corresponding to an end of a line of pixels of the image is stored, perform a second cost calculation on the stored data corresponding to the line and (v) reverse the direction of storing the data in the buffer. An order for the second cost calculations on the line of the data may be last in, first out. The data may be stored while the second cost calculations are performed. Data may not be removed from the buffer until the second cost calculation has been performed on the data.
USE OF SIMULTANEOUSLY RECEIVED VIDEOS BY A SYSTEM TO GENERATE A QUALITY OF EXPERIENCE VALUE
A primary video and a second instance of a reference video can be simultaneously transmitted to a system through at least a first node of a communication network, the second instance of the reference video configured to be compared to a first instance of the reference video stored by the system to generate at least one quality of experience (QoE) value that infers a perceptual quality of the primary video as received by the system. The QoE value can be received from the system. A determination can be made as to whether the QoE value is less than a threshold value. Responsive to determining that the QoE value is less than the threshold value, the perceptual quality of the primary video can be improved by allocating greater bandwidth for transmission of the primary video.

RECEPTION APPARATUS, RECEPTION METHOD, TRANSMISSION APPARATUS, AND TRANSMISSION METHOD
The present technology relates to a reception apparatus, a reception method, a transmission apparatus, and a transmission method permitting provision of an emergency warning service more suited to actual operation.
Provided is a reception apparatus including a reception section and a demodulation section. The reception section receives a physical layer frame transported as a broadcast signal on the basis of monitoring information that is included in upper layer signalling, signalling in a layer higher than a physical layer, and that is used to monitor a specific service. The demodulation section demodulates physical layer signalling acquired from the physical layer frame and monitors whether emergency warning information has been transported on the basis of emergency warning notice information acquired as a result of the demodulation. In the case where the emergency warning notice information indicates that the emergency warning information has been transported, the reception apparatus starts up automatically. The present technology is applicable, for example, to a transport system for transporting a physical layer frame compliant with the DVB-T2 standard.
Method of Operating Audio Systems, Corresponding Circuit, System and Computer Program Product
In accordance with an embodiment, a method of producing a TDM serial audio stream includes: receiving a plurality of input audio signal streams from an audio source clocked at an input clock frequency and producing therefrom a TDM serial output stream clocked at a TDM output clock frequency; obtaining the input clock frequency and the TDM output clock frequency by dividing a master clock frequency; writing audio signal samples from the input audio signal streams into a set of memory buffers at the input clock frequency; and producing the TDM serial output stream from audio signal samples buffered in the memory buffers by reading the buffered audio signal samples at the TDM output clock frequency.
Use of simultaneously received videos by a system to generate a quality of experience value
A primary video and a second instance of a reference video can be simultaneously transmitted to a system through at least a first node of a communication network, the second instance of the reference video configured to be compared to a first instance of the reference video stored by the system to generate at least one quality of experience (QoE) value that infers a perceptual quality of the primary video as received by the system. The QoE value can be received from the system. A determination can be made as to whether the QoE value is less than a threshold value. Responsive to determining that the QoE value is less than the threshold value, the perceptual quality of the primary video can be improved by re-routing transmission of the primary video to the system.
